When cold weather rolls in, everyone wants the same thing—to keep the heat inside the building, not leaking out into the chilly air. If you’re heating a metal building, shed, workshop, or garage, you may wonder: Can BlueTex insulation actually help during the winter?
Selecting the right metal building insulation determines whether your facility stays comfortable, controls condensation effectively, and operates efficiently for decades - or disappoints within seasons despite significant investment. BlueTex offers distinct insulation solutions, each optimized for specific building types, climate conditions, and usage patterns.
Understanding the differences between BlueTex Pro 2mm, Supreme 6mm, foil-only radiant barriers, and Thermal Wrap prevents purchasing products designed for different applications than yours. A warehouse in Texas has fundamentally different insulation needs than a heated workshop in Minnesota, and products that excel in one scenario underperform in another.
This comprehensive comparison examines each BlueTex product category, explaining which buildings, climates, and usage patterns each serves best. Rather than simply listing specifications, we'll explore the real-world performance differences that actually matter when choosing metal building insulation.
Before comparing specific products, identify your building's conditioning level - the single most important factor determining which insulation performs best.
Buildings never heated or cooled simply need to reach ambient outdoor temperature while blocking radiant heat from superheated metal surfaces. Storage facilities, equipment sheds, and seasonal-use structures fall into this category.
Goal: Reflect 97% of radiant heat to get the building close to ambient and utilizing ventilation to force hot air to escape.
Many facilities chose to use occasional heating or cooling during working hours or extreme weather - workshops, garages, airplane hangars, agricultural buildings, and most commercial warehouses.
Goal: "Take the edge off" temperature extremes, making spaces comfortable during occupancy without maintaining constant climate control 24/7.
Temperature-controlled facilities maintaining constant climate around the clock - barndominiums, office spaces within metal buildings, container living conversions, recreational rooms, or climate-controlled distribution centers.
Goal: Maintain consistent temperature year-round through continuous HVAC operation, requiring both radiant barriers and substantial R-value insulation.
BlueTex manufactures four distinct insulation categories serving different building types:
Foil-Only Radiant Barriers: Perforated pure aluminum (breathable, not vapor barriers)
Thermal Wrap: building wrap made from a tear-proof vapor/radiant barrier, pairs well with spray foam for a fully-conditioned building
BlueTex Pro 2mm: Foil-foam combination for warm and mixed climates
BlueTex Supreme 6mm: Thicker foil-foam for cold/wet climates and regular heating
Each product shares 97% radiant heat reflection but differs dramatically in permeability, thermal mass, and ideal applications.
Construction: Pure aluminum foil (double-sided or single-sided with white PE backing)
Key Feature: Micro-perforated (tiny holes every 1/2") making it breathable rather than a vapor barrier
Reflectivity: Blocks 97% of radiant heat
Strength: Tear-proof, puncture-resistant
Climate: Warm climates exclusively
Building type: Non-conditioned buildings never receiving heating or cooling
Primary goal: Pure radiant heat rejection without condensation control needs; the effect is like putting your building in the shade
Typical uses:
Hot, dry climate storage facilities
Well-vented structures in southern states
Equipment sheds in consistently warm regions
Buildings where moisture can escape naturally through ventilation
Perforated radiant barriers excel when you need maximum heat reflection without vapor barrier properties. The breathable construction allows moisture to pass through naturally, preventing trapped condensation in vented structures.
This product costs less than foil-foam alternatives since it eliminates the foam core entirely. For hot, dry climates where condensation never occurs and heating never happens, foil-only delivers appropriate performance without paying for capabilities you won't utilize.
All radiant barriers require a minimum 1/2" air gap on the foil side to function effectively. Without this air space, heat conducts directly through contact rather than reflecting back. It’s recommended to install a foil product on the bottom of roof purlins or wall girts to utilize the natural air gap in the cavities, rather than pressing it up directly against exterior metal.
Avoid foil-only radiant barriers if:
Your building experiences condensation or "sweating" on interior surfaces
You're in cold or mixed climates with heating seasons
You plan any heating or cooling (even occasional)
Humidity levels create moisture concerns
For these applications, choose vapor barrier products (Pro 2mm, Supreme 6mm, or Thermal Wrap) instead.
Construction: 16 mil tear-proof white non-woven slip-resistant base adhered to a heavy duty PE woven fabric laminated to a pure aluminum foil.
Key Feature: Designed for wrapping new buildings and pairing with R-value insulation for fully conditioned spaces
Reflectivity: Blocks 97% of radiant heat
Permeability: Complete vapor barrier (not perforated)
Texture: Back surface accepts spray foam directly or layers with batt insulation, foam board, etc
Climate: All climates
Building type: Fully conditioned buildings with 24/7 climate control
Heating/cooling: Continuous HVAC operation maintaining constant temperature
Typical uses:
Barndominiums (barn conversions to living spaces)
Office spaces within metal buildings
Container living conversions
Recreational/game rooms requiring year-round comfort
Climate-controlled distribution centers
Any metal building serving as primary living space
Fully conditioned spaces require both radiant barrier performance and substantial R-value to keep the conditioned air inside the space. We recommend you reference local energy codes and recommendations for the recommended R-value in your climate zone. Thermal Wrap provides the radiant/vapor barrier layer while you add the recommended R-value insulation behind it, toward the interior of the living space.
The textured white backing has a grippy surface that pairs excellently with spray foam, creating integrated systems maximizing thermal performance. Install Thermal Wrap closest to exterior metal (blocking radiant heat first) with the air gap between the sheet metal and the foil, then apply spray foam or batt insulation achieving code-required R-values. You can use hat channels, girts, or furring strips to create the air gap on the exterior before the siding or roofing goes on.
Most cold climates require R-19 to R-30 in walls and R-30 to R-49 in roofs. Consult local building codes for specific requirements in your area.
New construction: Install Thermal Wrap first (radiant barrier layer) with the air gap between the foil surface and the exterior metal, then add R-value insulation inside the cavities, during framing and finishing. It can also be laid out over roof purlins below metal roofing (with an air space).
Retrofit: For buildings with existing vapor barriers, we recommend you use a perforated foil-only radiant barrier instead. For buildings without vapor barriers, Thermal Wrap creates the vapor barrier layer before adding R-value.
Thermal Wrap alone (without added R-value) provides insufficient insulation for fully conditioned spaces. If you're not maintaining constant 24/7 climate control or not adding substantial R-value insulation, choose Pro 2mm or Supreme 6mm instead.
Construction: Three-layer system of pure reflective aluminum foil, EPE 2mm (0.08” thick) blue foam, and a PE bright glossy white woven fabric that's easy to clean.
97% reflective pure aluminum foil (exterior side)
2mm EPE foam core (lightweight, flexible)
Glossy white PE woven fabric (interior side)
Reflectivity: Blocks 97% of radiant heat when installed with air gap of ½” or more
Permeability: Complete vapor barrier when seams are sealed properly
Strength: Tear-proof, puncture-resistant construction
R-value: Approximately R-1 (honest specification, not inflated marketing)
Widths available: 50" (spans 4' framing) and 62" (spans 5' framing)
Features: 1" peel-and-stick adhesive edge on foil side for ease of installation and overlapping
Climate: Warm and mixed climates
Building type: Non-conditioned and semi-conditioned buildings
Heating/cooling frequency: 5-8 hours per week or less (occasional use)
Typical uses:
Garages receiving occasional heating during winter projects
Workshops with portable heaters or AC units used intermittently
Airplane hangars
Storage facilities needing condensation control
Agricultural buildings with minimal climate control
Equipment sheds in areas experiencing condensation
The Pro 2mm fits most customers' needs most of the time. Buildings benefiting most from Pro 2mm - garages, workshops, airplane hangars, barns - typically involve work getting done with very little supplemental heating or cooling.
The modest 2mm thickness provides appropriate thermal mass for occasional climate control via heating/cooling, without excessive cost of thicker insulation that is rarely useful. When you're heating a workshop for 4-6 hours on Saturday mornings, the Pro 2mm retains that heat adequately without justifying Supreme 6mm's premium pricing.
Pro 2mm provides basic to mild condensation control in warm and mixed climates. The foam core plus sealed seams create a vapor barrier, preventing moisture-laden air from contacting cold metal surfaces where condensation can form.
Installation requirement for vapor barrier performance: Use included 1" adhesive edge plus 3" white vapor barrier tape over all seams. Unsealed seams are weak points that allow warm-moist air to leak into the cold cavity, defeating the vapor barrier.
Hot climates: Excels at reflecting radiant heat from superheated metal panels (often reaching 150-170°F on sunny days). The white interior surface brightens spaces dramatically compared to exposed metal.
Mixed climates: Provides year-round performance - summer cooling via radiant barrier, winter condensation control via vapor barrier, adequate thermal mass for occasional heating.
Cold wet climates with minimal heating: Works adequately if you're never heating or heating very occasionally (less than 8 hours weekly). For regular heating (8+ hours weekly), Supreme 6mm performs better.
Choose Supreme 6mm over Pro 2mm if:
You're in very cold/wet climates with severe condensation issues
You heat regularly (2-4 hours daily or 8-10+ hours weekly)
Maximum moisture control matters more than cost savings
You want buildings heating faster when HVAC systems run
Construction: Three-layer system of pure reflective aluminum foil, XPE 6mm (0.24” thick) blue foam, and a PE bright glossy white woven fabric that's easy to clean and won’t rip or tear.
97% reflective pure aluminum foil (exterior side)
6mm XPE foam core (3x thicker than Pro 2mm, dense, robust)
Glossy white rip-stop PE woven fabric (interior side)
Reflectivity: Blocks 97% of radiant heat when installed with an air gap of ½” or more
Permeability: Complete vapor barrier when seams are sealed properly
Strength: Tear-proof, puncture-resistance (superior to Pro 2mm)
R-value: Approximately R-1 (honest specification, foam thickness adds thermal mass not R-value)
Foam type: XPE (cross-linked polyethylene) - denser and more durable than EPE
Widths available: 50" (spans 4' framing) and 62" (spans 5' framing)
Features: 1" peel-and-stick adhesive edge on foil side for ease of installation and overlapping
Climate: Cold climates (areas with longer cold seasons)
Building type: Non-conditioned and semi-conditioned buildings in cold regions
Heating/cooling frequency: 8-10+ hours per week or 2-4 hours daily (regular use)
Typical uses:
Heated workshops in northern states
Garages with regular heating during winter months
Barns housing temperature-sensitive equipment
Aircraft hangars requiring condensation control in cold climates
Agricultural facilities in very cold regions
Any building with severe condensation/moisture problems
Supreme 6mm provides "great condensation control in colder climates using heating." The thicker XPE foam offers superior moisture prevention compared to Pro 2mm's EPE foam.
Why this matters: Cold climate buildings face severe condensation when warm interior air (from heating) contacts frigid exterior metal. Moisture drips onto equipment, creates ice buildup, promotes rust, and damages stored items. Supreme 6mm's enhanced vapor barrier performance prevents this moisture migration more effectively than thinner alternatives.
The thicker foam core enables the building interior to more easily stay above the dew point than thinner products like the Pro 2mm. Think of your building like a refrigerator - thicker insulation retains conditioned air longer and responds faster when HVAC systems cycle on.
Practical benefit: If you're heating a workshop for 3 hours every evening after work, Supreme 6mm reaches comfortable temperature faster and maintains it better, reducing energy consumption and improving comfort during your actual working time.
XPE (Cross-Linked Polyethylene) in Supreme 6mm:
Denser, more robust construction
Superior durability
Enhanced moisture resistance
Better performance in extreme temperature swings
Justifies premium cost in demanding applications
EPE (Expanded Polyethylene) in Pro 2mm:
Lightweight, flexible construction
Sufficient for most warm and mixed climate applications
Lower cost that still provides excellent heat control (blocks 97% of radiant heat) and minimal moisture control
Appropriate when extreme conditions don't occur
Choose Supreme 6mm when:
Winter temperatures regularly drop below freezing
You're experiencing severe condensation problems Pro 2mm can't solve
You heat regularly (not just occasionally) and want buildings responding faster
Maximum durability matters and you want a premium insulation
Moisture issues threaten equipment, inventory, or building integrity
Both BlueTex Pro 2mm and Supreme 6mm deliver:
Radiant heat reflection: 97% blocking capability when installed with proper air gaps
Vapor barrier performance: Complete moisture prevention when seams are sealed
Aesthetic appeal: Glossy white interior surface creating clean, professional appearance (washable and pressure-washable)
Versatile installation: Suitable for walls, ceilings, and rooflines
Easy seaming: 1" adhesive edge on foil side for overlap connections, easy to seal with 3” vapor barrier tape
Mold/mildew resistance: Neither product promotes growth, ensuring healthier environments
Tear-proof construction: Both withstand installation wear and tear
Pure aluminum: Never use cheap Mylar alternatives that deteriorate quickly
| Feature | Pro 2mm | Supreme 6mm |
|---|---|---|
| Foam thickness | 2mm | 6mm (3x thicker) |
| Foam type | EPE (lightweight, flexible) | XPE (dense, robust) |
| Best climate | Warm & mixed | Cold |
| Heating frequency | ≤8 hours/week (occasional) | 8–10+ hours/week (regular) |
| Condensation control | Basic / mild | Maximum / great |
| Heating response | Standard | Faster temperature changes |
| Durability | Excellent | Superior |
| Cost | Lower | Premium |
| Most common use | Garages, workshops in warm areas | Heated buildings in cold climates |
Hot climates (minimal heating needs): Pro 2mm provides appropriate performance without wasting money on cold-climate capabilities you won't use.
Mixed climates (moderate winters, hot summers): Pro 2mm handles most applications unless you're heating regularly during winter.
Cold climates (extended freezing temperatures): Supreme 6mm delivers superior condensation control and faster heating response justifying its premium cost.
BlueTex explicitly encourages combining Supreme 6mm on roofs with Pro 2mm on walls in cold climates, providing excellent condensation control at lower cost with minimal effect on heating and comfort.
Why this works:
Heat rises - roof insulation matters most for heat retention
Roof surfaces experience most severe condensation from warm air rising to cold surfaces
Wall insulation still controls condensation but faces less severe conditions
Combined approach balances performance and budget effectively
Installation approach:
Install Supreme 6mm on entire roof/ceiling (maximum condensation control where it matters most)
Install Pro 2mm on all walls (adequate performance at lower cost)
Seal all seams meticulously regardless of product, connecting the 2mm to the 6mm with the vapor barrier seam tape
This hybrid approach saves 30-40% compared to Supreme 6mm throughout while delivering 90%+ of the performance benefits.
All BlueTex foil products (Pro 2mm, Supreme 6mm, Thermal Wrap, foil-only) require 1/4" to 1/2" minimum air gap between foil and exterior metal for radiant barrier function. This gap does not have to be vented, but it can be.
Installation method: Attach insulation to bottom of purlins or girts rather than pressing against roof/wall panels. This naturally creates required air space allowing radiant heat to reflect back rather than conducting through direct contact. Otherwise, if you need roof/wall cavities to insulate further, install furring strips first, then add the foil insulation and the regular R-value
Pro 2mm, Supreme 6mm, and Thermal Wrap all function as vapor barriers only when installed air-tight.
Sealing process:
Use included 1" peel-and-stick adhesive edge for initial overlap connection
Add 3" white vapor barrier tape over all seams for proper sealing, press tape firmly on seams to initiate a bond
Seal around all penetrations (HVAC, electrical, doors, windows) with tape or spray foam
Pay special attention to perimeter edges where insulation meets walls, roofs, openings, if need be, use wider tape for large areas
For cold climates: Add 3" foil tape on the exterior side during new construction for reinforced sealing.
Foil-only exception: Perforated radiant barriers don't require seam taping since they're intentionally breathable. You can tape them for finished appearance but it's not functionally necessary.
Can you install BlueTex on the roof only and skip the walls?
BlueTex's answer: It depends on your goals. If you're primarily addressing condensation on roof purlins or keeping roof radiant heat out, roof-only installation delivers significant benefits. However, comprehensive installations covering walls and roof provide maximum comfort and condensation control throughout the building.
Many customers start with roof installation (where heat transfer is most severe) then add walls later if needed.
Yes! Combining Supreme 6mm on roofs with Pro 2mm on walls saves money while providing excellent cold-climate performance. This approach balances performance and budget effectively.
The radiant barrier layer on all of our products is the same foil. When installed with the air gap on the foil side, all products will reject heat gain similarly. If you’re in an extreme climate, you may find that the Supreme 6mm's thicker foam enables faster heating inside semi-conditioned buildings.
For non-conditioned and semi-conditioned buildings: No. Pro 2mm and Supreme 6mm provide appropriate performance alone.
For fully conditioned buildings (24/7 climate control): Yes. Use Thermal Wrap paired with spray foam or batt insulation meeting local code requirements.
Warm climates: Start with Pro 2mm ensuring meticulous seam sealing. Most condensation issues resolve with proper vapor barrier installation.
Cold climates: Supreme 6mm provides maximum moisture control. If condensation persists, verify complete seam sealing and consider adding additional R-value inside to keep the surfaces above the dew point.
BlueTex products are DIY-friendly. The adhesive edges, tear-proof construction, and straightforward installation process suit both professional contractors and capable DIY builders.
Installation time: Most single-bay garages complete in one day with at least 2 helpers. Large commercial buildings may take several days depending on square footage and crew size.
Match roll width to your framing spacing:
50" wide rolls: Span 4' on-center framing with 1" overlap each side
62" wide rolls: Span 5' on-center framing with 1" overlap each side
Wider rolls reduce installation time and create fewer seams requiring taping.
Choosing the right BlueTex product depends on three primary factors:
Building conditioning level: Non-conditioned, semi-conditioned, or fully conditioned?
Climate: Hot, mixed, or cold?
Heating/cooling frequency: Never, occasionally (≤8 hrs/week), or regularly (8-10+ hrs/week)?
Decision framework:
Hot climate + no heating = Foil-only radiant barrier (if vented and dry)
Hot climate + no/minimal heating/cooling = Pro 2mm (most common choice)
Mixed climate + occasional heating/cooling = Pro 2mm (fits most needs)
Cold climate + regular heating = Supreme 6mm (maximum performance)
24/7 climate control regardless of climate = Thermal Wrap + R-value insulation

Evaluate whether stores carry products specifically designed for metal buildings versus general residential insulation. Metal building applications require:
Radiant barriers blocking 97% of heat from hot metal surfaces
Vapor barriers controlling condensation in temperature-differential situations
Wide rolls (50"-93") spanning metal building framing spacing efficiently
Pure aluminum foil (not cheap Mylar alternatives that deteriorate quickly)
Stores specialising in metal building insulation provide the right products, while general retailers may offer generalized products designed for stick-frame residential construction that perform poorly in metal building applications.
Metal building insulation involves complex considerations—conditioning levels, climate factors, moisture management, installation methods. Retailers providing building science expertise ensure successful installations rather than leaving customers guessing.
Evaluation criteria:
Do they provide detailed installation guides for metal building applications?
Can you speak with technical experts about specific project questions?
Do they offer free samples for evaluation before large orders?
Are product specifications honest (actual R-values) or exaggerated (inflated marketing claims)?
Insulation products are bulky and heavy, making shipping costs significant portions of total project expenses.
Compare carefully:
Free shipping thresholds ($100+ at BlueTex, varies elsewhere)
Shipping speeds (ships out the same-day vs. 5-7 business days)
Regional vs. nationwide availability
Store pickup options eliminating shipping entirely
Calculate total delivered cost including shipping before comparing "low" product prices that carry expensive shipping fees.
Metal building projects operate on schedules. Waiting weeks for backordered materials creates costly delays.
Prioritize retailers:
Maintaining substantial inventory for immediate shipment
Providing real-time stock status online or by phone
Offering alternative in-stock products when preferred items are unavailable
Operating as direct manufacturers controlling supply chains
Metal buildings represent long-term investments. Insulation warranties protect against premature failure requiring expensive replacement (materials plus labor).
Verify warranty terms:
Duration (limited lifetime vs. 1-5 years)
Coverage scope (material defects vs. installation errors)
Claim procedures (simple vs. bureaucratic)
Manufacturer reputation (established vs. fly-by-night)
Online purchases involve risk—products may not match expectations or suit specific applications.
Understand return terms:
Return windows (30 days vs. no returns)
Restocking fees (0% vs. 20%+)
Return shipping costs (customer pays vs. free returns)
Local return options (ship back vs. return to nearby store)
Stores with physical locations (Home Depot, Lowe's, Menards) offer easiest returns—simply bring products to local stores.
Research retailer reputation before purchasing, particularly from specialised online-only stores.
Check multiple sources:
Better Business Bureau ratings
Google reviews
Industry forums and metal building communities
Social media presence and customer interactions
Established retailers with decades of operation and thousands of positive reviews demonstrate reliability that new stores can't match.

Garage insulation transforms uncomfortable spaces into functional workshops, climate-controlled storage areas, and comfortable extensions of your home. Whether you're converting your garage into a home gym, protecting temperature-sensitive items, or simply making winter projects more bearable, selecting the right insulation rolls determines whether your investment delivers lasting results or disappoints within seasons.
Garage insulation differs fundamentally from house insulation. Garages rarely receive full-time climate control, they experience dramatic temperature swings, and their metal or minimally insulated doors create unique thermal challenges. Understanding these differences prevents purchasing products designed for residential walls that perform poorly in garage applications.
This comprehensive 2026 guide examines everything homeowners need to know about buying garage insulation rolls - from understanding product types and installation requirements to selecting solutions that actually work in real-world garage conditions.
Most garages aren't heated or cooled constantly. You might run a space heater during winter projects or a portable AC unit during summer, but garages typically exist in semi-conditioned or non-conditioned states most of the time.
Traditional fiberglass batt insulation designed for fully heated/cooled homes provides minimal benefit in garages. R-value (thermal resistance) matters primarily when maintaining constant temperature differentials - exactly what garages don't do.
Garage doors, roof panels, and walls facing direct sun absorb tremendous heat - often reaching 140-160°F on summer days. These superheated surfaces radiate heat inward, making garages feel like ovens regardless of the outside air temperature.
This radiant heat transfer dominates garage thermal dynamics far more than conductive heat flow through materials. A thin radiant barrier reflecting 97% of radiant heat delivers better cooling than thick fiberglass insulation attempting to slow conductive heat transfer.
Garages experience condensation when temperature differentials occur - warm humid air contacting cold surfaces in winter, or cool air-conditioned air meeting hot surfaces in summer. Condensation damages stored items, promotes rust on tools and vehicles, and creates unhealthy mold conditions.
Effective garage insulation must include vapor barriers preventing moisture-laden air from reaching surfaces where condensation forms or be fully vented to keep things dry.
Foil-foam insulation combines reflective aluminum foil with foam cores, creating all-in-one products addressing radiant heat, providing modest thermal resistance, and serving as vapor barriers.
BlueTex Pro 2mm exemplifies this category for garage applications. The three-layer construction includes:
97% reflective pure aluminum foil blocking radiant heat
EPE 2mm blue foam providing approximately R-1 thermal resistance
Bright glossy white PE woven fabric creating a finished interior appearance
Available in multiple widths (22", 50", and 62"), these products suit different garage applications from residential garage doors (22” wide rolls) to full wall/ceiling coverage in detached garages or workshops (larger 50” and 62” wide rolls).
The 2mm thickness provides appropriate performance for semi-conditioned garages where you occasionally heat or cool the space (5-8 hours weekly) without excessive cost for capabilities you won't fully utilize. It’s also the right thickness to add to garage doors without disrupting their ability to open and close.
BlueTex Supreme 6mm uses thicker XPE (cross-linked polyethylene) foam - three times thicker than the 2mm Pro - providing enhanced moisture control and faster heating/cooling response when you're running climate control more regularly (8-10+ hours weekly).
The Supreme 6mm particularly benefits garages in very cold climates where severe condensation becomes problematic. The tear-proof construction withstands installation challenges while providing maximum vapor barrier performance on the walls and roofline of the garage. For roll up garage doors however, we recommend the 2mm Pro.
Both products include 1" peel-and-stick adhesive edges on the foil side for easy installation and the 3” wide vapor barrier seam tape will close and seal your seams. The glossy white interior surface dramatically brightens garage spaces compared to exposed framing or dingy old insulation - an often-underappreciated benefit improving lighting and creating cleaner, more pleasant work environments.
For garages where moisture control isn't the primary concern - hot, dry climates or well-vented spaces - perforated radiant barrier foil delivers excellent heat rejection alone.
Double-Sided Radiant Barrier Foil features pure aluminum on both surfaces reflecting 97% of radiant heat. The micro-perforated construction (tiny holes every 1/2") makes it breathable rather than a vapor barrier, suitable for vented garages where moisture can escape naturally.
This heavyweight foil (28.6 lbs per 1,000 sq ft) is tear-proof and won't rip during installation. Available in 4' wide and 5’ wide rolls, it installs quickly across garage ceiling joists or wall studs.
Single-Sided Radiant Barrier Foil + White provides the same 97% reflection with a bright white PE backing for finished appearance - particularly appealing when the white side faces inward creating a clean, bright garage interior.
Both foil-only products require at least 1/2" air gap on the foil side to function effectively. The air space enables radiant heat to reflect back rather than conducting through direct contact with adjacent surfaces.
Garage doors represent the largest thermal weak point in most garages. Standard metal doors conduct tremendous heat, making garage doors painfully hot to touch on sunny days and contributing massively to garage heat gain.
BlueTex 2mm Residential Garage Door Insulation Kits are specifically designed for panel-style residential garage doors typically 7-8 feet tall.
Kit options:
Single Car Kit (8H x 10W): Covers standard single garage doors
Double Car 4-Panel Kit (7H x 18W): Covers double doors with 4 horizontal panels
Double Car 5-Panel Kit (8H x 18W): Covers double doors with 5 horizontal panels
Each kit includes:
BlueTex Pro 2mm 22" wide foil-foam insulation (appropriate length for door size)
1 roll of 1.5" x 180' double-sided tape for attaching insulation to door panels
1 roll of 2" x 196' white seam tape for securing edges and seams
12 fastener sets (screws/washers) for optional permanent attachment
Utility knife for cutting insulation to fit
The 22" width suits standard residential garage door panel heights perfectly. The thin 2mm profile allows doors to continue rolling on tracks without binding - critical for overhead door operation.
The double-sided tape attaches insulation to door interior surfaces around panel perimeters. The white seam tape covers edges creating finished appearance while providing additional adhesion. Optional screws/washers permanently secure insulation if desired.
Installation time: Most homeowners complete single door installations in 1-2 hours, double doors in 2-3 hours.
Performance benefits:
Reflects up to 97% of radiant heat from door surfaces
Reduces heat transfer making garage more comfortable
Controls basic condensation on metal door surfaces
Brightens garage interior with glossy white surface
Allows doors to operate normally without binding
BlueTex 2mm Pro Roll-Up Garage Door Kits address commercial-style roll-up doors common in workshops, equipment storage, and commercial garages.
These doors present unique challenges - they roll up into coils above door openings, so insulation must be thin enough to allow rolling while still providing thermal benefits.
The 2mm Pro products provide perfect thickness - substantial enough to block radiant heat and control condensation, yet thin enough (approximately 1/8" total thickness) to allow doors to roll up normally.
Kit options:
Single Door Kit (50” wide 150 sq ft): Covers up to a 12x12 roll up door
Double Door Kit (50” wide 210 sq ft): Covers two 10x10 roll up doors
Oversized Door Kit (50” wide 300 sq ft): Covers two 11x11 roll up doors (or a single door up to 295 sq ft)
Multi Door Kit 10’/15’ Tall (50” wide 700 sq ft): Covers from three to six 10x10 roll up doors
Multi Door Kit 8’/12’ Tall (62” wide 700 sq ft): Covers up to four 12x12 doors
Each kit includes:
BlueTex Pro 2mm foil-foam insulation (check kit for width sizes)
Double-Sided 1.5" x 180' tape for attaching insulation to door panels (number of rolls vary by kit size)
3" x 180' white seam tape for securing edges and seams (number of rolls vary by kit size)
Fastener sets (screws/washers) for optional permanent attachment
Utility knife for cutting insulation to fit
Performance for roll-up doors:
Dramatically reduces radiant heat from doors catching direct sun
Prevents condensation forming on interior door surfaces
Adds minimal weight without affecting door operation
Creates finished appearance on interior door surface
Detached garages, workshops, and pole barn garages benefit from comprehensive wall and ceiling insulation beyond just door treatment.
In summer, superheated roof surfaces radiate tremendous heat downward. In winter, any heat you generate rises toward the ceiling. Insulating your ceiling is the best place to start when trying to regulate the temperature or moisture inside a garage.
Product selection: BlueTex Pro 2mm 50" or 62" wide depending on ceiling joist spacing (typically 4' or 5' on-center in garages).
Installation approach: Attach insulation to bottom of ceiling joists/trusses, foil side facing upward toward roof with the required air gap. This positioning reflects back the radiant heat from the hot roof, while creating a vapor barrier preventing warm interior air from contacting cold roof surfaces in winter.
Screw the BlueTex™ edges into joist bottoms with screws and locking insulation washers. Seal all seams with white vapor barrier tape for condensation control.
After ceiling, wall insulation provides secondary benefits - particularly walls receiving direct sun exposure during summer when heat gain is an issue.
Product selection: BlueTex Pro 2mm products in widths matching wall stud spacing.
Installation approach: Install vertically along studs (preferred) or horizontally across studs (only when spacing doesn’t allow for vertical installation), keeping the foil side facing outward toward exterior walls. Ensure an air gap exists between foil and exterior sheathing/siding, you do not want to press the foil up against the metal panels.
For attached garages sharing walls with conditioned house spaces, prioritize insulating the garage side of shared walls - preventing garage temperature extremes from affecting adjacent house areas.
Some detached garages may have old, failing fiberglass insulation - compressed, dirty, falling down, or providing minimal benefit.
Rather than removing the old insulation (messy, time-consuming, potentially hazardous if containing mold or pests), you can install BlueTex products over the existing insulation.
The new layer creates a clean vapor barrier surface, holds up old insulation preventing further sagging, and provides radiant heat control (when you have an air gap between the foil and the old insulation) that fiberglass alone never delivered.
Attach new insulation to the bottom of joists/studs, creating a new interior air tight surface while containing old insulation behind it. For the radiant barrier benefit, ensure there’s an air gap between the foil surface and the old insulation or remove the old insulation first.
Garages in consistently warm regions face primarily cooling challenges - rejecting solar heat gain.
Priority: Radiant barrier performance. Block 97% of radiant heat from superheated surfaces.
Recommended products:
Garage doors: BlueTex 2mm Residential or Roll-Up Garage Door Kits
Ceilings: BlueTex Pro 2mm or radiant barrier foil-only
Walls: BlueTex Pro 2mm or radiant barrier foil-only; focus on sun-exposed walls first, if budget limits full coverage
Additional strategy: Pair BlueTex with ventilation. Ridge vents, gable vents, or exhaust fans evacuate hot air, while radiant barriers prevent most heat from entering initially.
Garages in consistently cold regions face heating challenges and severe condensation.
Priority: Vapor barrier integrity preventing moisture-laden warm air from contacting cold surfaces.
Recommended products:
All applications: BlueTex Pro 2mm minimum; Supreme 6mm for severe cold/condensation
Critical sealing: Use 3" white vapor barrier tape over all seams
Additional strategy: Small electric heaters make cold-climate garages tolerable during projects. Vapor barriers prevent condensation when you introduce heat, protecting tools and stored items from moisture damage.
Garages experiencing both hot summers and cold winters need products performing in both extremes.
Priority: Year-round radiant barrier plus vapor barrier for winter condensation control.
Recommended products: BlueTex Pro 2mm provides excellent balance - summer cooling via radiant barrier, winter condensation control via vapor barrier, appropriate thermal mass for occasional heating/cooling. If you live in a particularly cold and wet climate, like the PNW, we recommend using the BlueTex Supreme 6mm for maximum moisture control in your garage.
Basic tools:
Utility knife or scissors for cutting insulation
Measuring tape
Drill with a hex head driver bit
Straightedge for cutting guidelines
Additional materials to order:
Extra white vapor barrier seam tape (3" wide recommended for most projects)
Screws and large washers for secure attachment
Double-sided tape for garage door installations
Radiant barriers only work when the foil faces an air space. The air space does NOT have to be between the foil and the hot surface, it can be on the opposite side, if the foil is facing inside the garage for example. Without gaps, heat conducts directly through contact so this air gap is critical to performance; the air gap does not have to be vented either, it can be a dead air space and still work.
Critical installation detail: When installing insulation on ceiling joists or wall studs, attach insulation to the bottom of the framing members rather than pressing against roof/wall sheathing. This naturally creates about a 2”+ air gap, meeting the requirement of a 1/2" minimum air gap.
For condensation control, seal every seam, penetration, and edge. Use 3” or 4” wide vapor barrier tape reinforcing all seams. For tears in your insulation, use the 6” wide vapor barrier repair tape.
Pay special attention to perimeter edges where insulation meets walls, doors, and openings - common locations for air leakage defeating vapor barriers.
Calculate square footage carefully before ordering. Contact the insulation manufacturer if you need help calculating. Measure garage dimensions including:
Ceiling area (length x width)
Gable ends
Wall areas requiring coverage
Garage door sizes
Account for 5-10% waste from cutting and fitting around obstacles.
When insulating garages comprehensively, order all materials together:
Insulation rolls in correctly sized widths
Vapor barrier seam tape
Fasteners (screws/washers)
Garage door kits, if applicable

Selecting metal building insulation represents one of the most important decisions affecting your facility's long-term comfort, energy efficiency, and operational costs. Yet many building owners approach this decision backwards - focusing on price per square foot or impressive-sounding R-value claims rather than understanding which product characteristics actually matter for metal building applications.
Metal buildings behave fundamentally differently than conventional stick-frame construction. The physics of heat transfer, moisture dynamics, and thermal performance require different evaluation criteria than residential insulation purchases. Making uninformed decisions based on residential insulation logic leads to disappointing results and wasted investment.
This guide examines the seven essential factors that genuinely determine whether metal building insulation delivers promised performance or becomes an expensive disappointment. Understanding these factors before purchasing prevents costly mistakes and ensures your building performs optimally for decades.
The single most critical factor - yet most commonly overlooked - is how you'll actually use the building. Insulation products optimized for one conditioning level may not perform optimally in other applications.
Buildings that are never heated or cooled need insulation that reaches ambient air temperature while blocking radiant heat. Storage facilities, equipment sheds, and seasonal-use structures fall into this category.
What matters: Radiant barrier performance blocking 97% of heat from superheated metal panels. R-value contributes minimally since you're not maintaining temperature differentials.
Product selection: BlueTex Pro 2mm provides radiant barrier plus vapor barrier for condensation control. Radiant barrier foil-only products work in hot, dry climates where moisture isn't a concern.
What doesn't matter: Thick foam cores, high R-value insulation, or products designed for constant climate control. Their benefits are wasted or ineffective in non-conditioned spaces, making them a wasted investment.
Many facilities receive occasional heating or cooling during working hours or extreme weather - manufacturing facilities, workshops, airplane hangars, agricultural buildings.
What matters: Matching thermal mass to heating/cooling frequency. More frequent climate control justifies a foam core that controls moisture while the radiant barrier layer enables faster temperature changes.
Product selection:
Occasional use (5-8 hours weekly): BlueTex Pro 2mm provides heat control and basic condensation protection without excessive cost
Regular use (8-10+ hours weekly): BlueTex Supreme 6mm delivers fast heating/cooling with its radiant barrier layer and thicker foam core. It also inhibits condensation best in cold wet climates.
What doesn't matter: Expensive or thicker R-value insulations designed for 24/7 climate control. Semi-conditioned buildings don't maintain constant temperature, making traditional insulation systems unnecessary.
Temperature-controlled facilities maintaining constant climate 24/7 - distribution centers, pharmaceutical storage, office spaces within metal buildings - require a more comprehensive approach.
What matters: Combining radiant barrier with sufficient R-value insulation meeting code requirements for your climate zone.
Product selection: BlueTex Thermal Wrap (installed with the radiant/vapor barrier facing the exterior metal with an air space) paired with spray foam (or any other R-value insulation).
What doesn't matter: Claims that thin foil-foam products alone suffice for fully conditioned spaces. They don't. You need actual R-value insulation paired with radiant barriers to get the right protection and results.
Understanding your building's conditioning level before shopping prevents purchasing inappropriate products that can't deliver desired results, regardless of quality.
Your geographic location and dominant weather patterns determine which insulation characteristics provide maximum benefit.
Buildings in consistently warm regions face cooling challenges - keeping oppressive heat out.
Critical factor: Radiant barrier performance. When exterior metal panels reach 150-170°F on sunny days, blocking 97% of that radiant heat delivers immediate cooling.
Product requirements: Pure aluminum foil (97% reflective), proper air gap installation, adequate ventilation pairing.
Secondary consideration: Vapor barrier quality matters less in hot, dry climates where condensation rarely occurs.
Recommended: BlueTex Pro 2mm for most applications, radiant barrier foil-only in vented structures.
Buildings in consistently cold regions face heating challenges and severe condensation issues.
Critical factor: Vapor barrier integrity prevents moisture-laden warm air from contacting frigid exterior metal where condensation forms.
Product requirements: Tear-proof construction, thicker foam cores for enhanced moisture control, meticulous seam sealing.
Secondary consideration: Modest thermal mass & the radiant barrier layer help buildings heat faster, reducing energy consumption.
Recommended: BlueTex Supreme 6mm for maximum moisture control through tear-proof XPE foam.
Buildings experiencing both hot summers and cold winters require products performing in both extremes.
Critical factor: Identifying your primary challenge - cooling or heating - then verifying adequate secondary performance.
Product requirements: Year-round radiant barrier performance plus vapor barrier for condensation control during heating season.
Recommended: Select based on dominant concern. If cooling dominates, Pro 2mm works excellently. If severe winter condensation dominates, Supreme 6mm provides enhanced protection.
Not all reflective materials perform equally. Material composition dramatically affects both initial performance and long-term durability.
What to look for: Products using genuine pure aluminum foil providing 97% reflectivity.
What to avoid: Cheap Mylar-type materials (metallic-coated plastic films resembling potato chip bags) that deteriorate from UV exposure, temperature cycles, and age within years.
BlueTex uses pure aluminum exclusively - never cheap alternatives that look similar initially but fail prematurely. This material choice ensures decades of consistent performance rather than degradation requiring replacement.
Verification method: Request sample kits from manufacturers. Pure aluminum has distinctive weight, strength, and feel that cheap alternatives lack. Quality differences become immediately apparent when handling samples.
Radiant barriers only work when they actually reflect radiant heat. Verify manufacturers provide specific reflectivity percentages rather than vague claims. Look for data or technical specification sheets.
Industry standard: 97% reflectivity from pure aluminum surfaces when properly installed with required air gaps.
Red flags: Products without specified reflectivity percentages, claims exceeding 97% (impossible with aluminum), or reflectivity claims without air gap requirements mentioned.
Foam cores in foil-foam products serve dual purposes - modest thermal resistance and enhanced vapor barrier capability. Not all foams perform equally.
EPE (Expanded Polyethylene): Used in BlueTex Pro 2mm. Balances cost and performance for most applications. Provides approximately R-1 thermal resistance, is tear-proof, and a good vapor barrier when sealed properly.
XPE (Cross-Linked Polyethylene): Used in BlueTex Supreme 6mm. More durable, tear-proof material providing enhanced moisture resistance. The foil layer is also coated to protect it from the elements. Justifies premium cost in cold climates or severe condensation applications.
Both provide approximately R-1 thermal resistance per inch. The thickness difference (2mm vs 6mm) provides modest additional thermal mass enabling better condensation control. Both products feature a pure aluminum radiant barrier that allows for faster temperature changes when heating/cooling semi-conditioned buildings.
Critical evaluation factor: Does the manufacturer provide honest R-value specifications or make inflated claims?
BlueTex acknowledges their products provide approximately R-1 thermal resistance. Many competitors claim R-12, R-15, or even R-20 for similar thin foam products - claims that are unfounded, inflated, or outright deceptive.
Why this matters: Manufacturers making exaggerated R-value claims likely mislead about other performance characteristics as well. Honest specifications indicate trustworthy products and companies.
When R-value actually matters (fully conditioned buildings), pair foil-foam products with legitimate R-value insulation rather than believing marketing exaggerations.
Condensation causes more damage in metal buildings than inadequate insulation. Effective moisture control requires proper vapor barriers installed air-tight.
Vapor barriers: Foil-foam products like BlueTex Pro 2mm, Supreme 6mm, and Thermal Wrap prevent moisture migration when installed with sealed seams. Critical for condensation control.
Breathable products: Perforated radiant barrier foils (micro-perforated with tiny holes every 1/2") allow moisture to pass through. Suitable only for vented structures where moisture can escape naturally and the main goal is heat rejection.
Selection criteria: Buildings with any heating or cooling need vapor barriers. Only open-sided, well-vented structures in hot, dry climates can use breathable products without risk of trapping moisture.
Vapor barriers only work when installed air-tight. Unsealed seams, gaps around penetrations, or open edges allow moisture migration defeating the entire system.
What to look for: Products with integrated seam sealing solutions. BlueTex products include 1" peel-and-stick adhesive edges on the foil side for initial seam connection to ensure your install is flat and ready to seal.
Additional requirements: Manufacturers should recommend 3" vapor barrier tape reinforcing all seams. For cold climates or severe condensation, exterior foil tape provides additional protection during new construction.
Installation guidance: Quality manufacturers provide detailed seam sealing instructions rather than leaving critical details to guesswork.
Product dimensions directly impact installation labor costs - often exceeding material costs for large commercial projects.
50" wide rolls: Span 4' on-center framing with 1" overlap on each side for fastening. Perfect for buildings with 4' framing spacing.
62" wide rolls: Span 5' on-center framing with 1” overlap on each side. Ideal for buildings with 5' framing spacing.
Why this matters: Wider rolls covering your exact framing spacing reduce installation time by minimizing seams requiring taping and cutting. Calculate your building's framing spacing before ordering to select the best width.
Installation time impact: Using appropriately sized rolls can reduce installation labor by 30-40% compared to incorrectly sized rolls requiring more seams and cuts or unnecessary waste.
Many projects involve retrofitting over existing, failing insulation rather than tearing it all out or building new construction.
What to look for: Products designed for retrofit installation - flexible enough to install over existing insulation, attach to bottom of purlins or between girts, and create new vapor barrier surfaces without complete teardown.
BlueTex products excel in retrofit applications because they install over existing fiberglass without removal, creating clean new interior vapor barrier surfaces while holding up old insulation to prevent further sagging/failure.
Metal buildings represent substantial long-term investments requiring decades of reliable performance from insulation systems.
What to look for: Limited lifetime warranties demonstrating manufacturer confidence in long-term durability.
What to avoid: Short-term warranties (1-5 years), limited warranties with extensive exclusions, or products without any warranty coverage.
BlueTex products include Limited LIFETIME warranties when used inside metal buildings - demonstrating confidence that cheap alternatives can't match.
Why this matters: When insulation fails prematurely, replacement costs (materials plus labor) often exceed original installation expense. Warranty coverage protects this investment.
Evaluation criteria: Does the manufacturer provide:
Detailed installation guides for different applications
Technical support answering specific project questions
Building science expertise beyond mere product sales
Free sample kits for evaluation before large orders
BlueTex operates as building science experts rather than mere product sellers, providing genuine technical guidance helping customers select appropriate solutions rather than pushing highest-cost products regardless of needs.
Why this matters: Metal building insulation involves complex considerations - conditioning levels, climate factors, moisture management, installation methods. Manufacturers providing expert guidance ensure successful installations rather than leaving customers to guess.
Practical consideration: Commercial projects operate on schedules. Waiting weeks for materials creates costly delays.
What to look for: Manufacturers maintaining substantial inventory for immediate shipment. BlueTex keeps thousands of rolls in stock and has the capability to ship out the same day or next business day, preventing project delays.
These seven factors determine whether metal building insulation delivers promised performance or disappoints despite initial cost savings from cheap alternatives.
Evaluation checklist:
☐ Identified building conditioning level and usage pattern
☐ Understood climate zone priorities and primary thermal challenges
☐ Verified pure aluminum construction (not cheap Mylar alternatives)
☐ Confirmed honest R-value specifications without exaggerated claims
☐ Ensured appropriate vapor barrier capability for application
☐ Selected roll widths matching building framing spacing
☐ Verified comprehensive warranty coverage and manufacturer support
Prioritize these essential factors over simplistic price-per-square-foot comparisons. The cheapest material often becomes the most expensive choice when accounting for poor performance, premature failure, and replacement costs.
BlueTex manufactures and distributes metal building insulation directly, ensuring consistent quality control and immediate availability. Their commitment to pure aluminum construction, honest R-value specifications, comprehensive warranty coverage, and genuine building science expertise demonstrates why professionals trust BlueTex for commercial and residential metal building projects.
