      One of the challenges in metal buildings is how you're going to attach insulation to the inside of the metal framing. We will cover that on this page, but just remember that for this application, the basic goal is to create an “envelope” inside the frame, made from BlueTex™ insulation that is attached securely to the inside of the framing.

      The objective is to create a NEW interior air barrier, vapor barrier and thermal barrier with the foil side facing the exterior of the building and utilizing the gap created by the framing as the required airspace the foil side needs in order to act as a radiant barrier and reflect 97% of radiant heat BEFORE it enters the interior of the building. This will basically put the building “in the shade” from the heat, almost like it was instantly under a giant tree.

      Because not all buildings are identical, you may have to get creative with your installation when you have an existing building you're trying to retrofit for insulation. If you have a specific question about how to install BlueTex™ in your building, please email us pictures and/or drawings and we will be glad to help you. We do this everyday and have seen just about everything when it comes to installations and applications. Let our experts give you some advice: contact us by email or give us a call at 800-595-8772.

      PREP: HOW TO ATTACH TO THE METAL

      Before you begin your install, you need to determine how you're going to attach the product to your metal framing. As mentioned above, you may have to get creative if you have special circumstances, but we've got 3 great options that should work for most of our customers. The video below goes over the methods we suggest, and you can read below to get more detail on them as well as complete installation information.

      Choose the Best Way To Attach the Insulation

      You can find all of the supplies mentioned below on our Resources Page.

      OPTION 1: Using self-drilling screws

      For this method you'll attach the BlueTex™ by using a screw gun/drill (cordless works great) to attach round insulation washers with self-drilling screws into the framing.

      We recommend using some double-sided tape to hold the BlueTex™ up just until the screws are in place. Long-term the double-sided tape may not be strong enough to keep the insulation up on the bottom of the roof, but the addition of the screws (quick and easy!) will make this a strong, permanent hold. No pre-drilling is required when using these screws.

      For this approach, we recommend ¾" (5/8" will work too) screws with hex-shaped heads (as opposed to phillips heads). It's super easy if you get a magnetic nut-driver attachment for your drill to help hold and drive the screws into the metal. 

       

      OPTION 2: Using a pin system (2 methods)

      This is the absolute best option because it's simple, fast, and very effective.

      You attach pins to the framing, then push the BlueTex™ so the pins poke through, and secure them with locking washers.

      We have two options for using a pin system: self-adhesive pins and glue-attached perforated pins.

       

      OPTION 2A: Using self-adhesive (peel-and-stick) pins *BEST INSTALL METHOD*

      *BEST METHOD OVERALL* These pins are easy to use, just peel off the backing, stick them to the metal and then push the pin through the BlueTex™ before securing it with a locking washer.

      Note: the recommended maximum temperature for the adhesive on these pins is 140F. An easy solution to make sure they stay is to use a self-drilling screw to permanently attach the square base of the pin to the metal framing.

       

      OPTION 2B: Glue-attached perforated pins (Recommended for Quonset-style buildings)

      *We really only recommend this application for Quonset style buildings that have no framing, or a unique applications where you cannot use a screw to attach the pin into the metal.

      The base of this pin is perforated so you can use any adhesive (specifically one rated for higher temps) and attach it to the metal frame.

      To use these pins, you just apply a small dab of glue to the middle of the perforated base, apply the base to the metal and then let it harden over about 24 hours. 

      Pins can be attached and spaced about 24" apart. Once the pins have dried, then come in and install the insulation and "lock" it in place with the washers.

      You can find all of the supplies mentioned above on our Resources Page.

      Now that you know which method you're using to attach the product to the metal, let's get started with installation.

      Begin Your Installation

      STEP 1

      START AT THE BOTTOM: Use the floor of the building and the bottom part of the framing as your guide to start the first run. Install BlueTex™ so that the foil side is facing out of the building (away from you) with the tape tab facing DOWN (you actually will NOT use the tape tab on the first run of insulation). The easiest thing to do is remove the paper backing and fold the tap tab over the edge and stick to the back side of the insulation, basically, you are hiding the tape tab. 

      First, you will need to decide which method you want to use to attach the BlueTex™ insulation to the inside of the metal framing. 

      For SMALLER buildings using the double sided tape with washers and self-drilling screws works great. For LARGER buildings we recommend moving to the pin system and using NO tape.  

      Remember, you can easily cover the screws with our matching tape to make them disappear. Continue with this approach around the entire perimeter of the building until you're done with the first run across all of the bottom of the building. 

      STEP 2

      FINISH WALLS: Move up to the second run. At this point, you need to decide if you are going to 1) butt up the BlueTex™ insulation seams edge-to-edge or 2) overlap the seams a couple of inches (this is the BEST option of the two!).

      Depending on the install method you're using (explained up top), attach either pins or double sided tape to the framing.

      If you're going to butt the pieces up against one another, go ahead and begin that on this run. Start by positioning the bottom of the second piece so that it is butted up against the top edge of the bottom piece. Once it's attached to the frame, go back and peel the tape tab and securely seal the seam.

      If you're using pins and overlapping, you can use ONE pin for both layers with either one or two washers. Then attach the next piece of BlueTex™ and overlap the second piece over this one and through the pin as well.  

      At this point (or later at the end of the install) you can fold up the tape tabs and lay them on top of the above piece, pressing down to secure the hold. If needed, we can provide extra tape to help you make the seam look finished and extra clean.  

      After you finish the second run, REPEAT with the next run of foil and continue following steps 1 and 2 until you reach the top of your wall. 

      STEP 3

      THE ROOFLINE: Ideally, you want to keep a continuous new interior surface and connect the walls to the bottom of the roofline. Usually, you can just keep going without any difficulties, but if this is a challenge, please send us some pictures and we can offer some technical advice to help you.

      If you have square tubing connecting your gable end to the roof, be sure to watch the video on how to attach pins in the corners.  

      Connecting the gable ends to the roofline may also require some insulation tape to get a good airtight seal. Continue up the roofline until both sides meet in the middle. Here you have to decide: are you going to vent the building, or not vent it?

      VENTED VS. NON-VENTED

      NON-VENTED BUILDINGS: If you are not venting the building, then overlap the sides at the center ridge about 6" - 10" inches and secure with pins/washers or screws/washers. Taping the top seam is optional.

      VENTED BUILDINGS: If the building is ventilated, then leave a 3-6” slit/gap at the top of the roof, regardless of whether you have ridge vent or not! If you do not have ridge vents, but you do have other types of vents (ex. wind turbines, static vents, gable vents etc.), you will still leave the slit on the top ridge, AND you will also want cut holes in the BlueTex™ insulation directly below the vent in the roof. Basically, if you have a hole in the roof, you want a matching hole in the insulation directly below the vent.

      STEP 4

      FINISH UP: Finish closing/taping all the seams on the walls and roofline. Use extra tape to “clean up” any exposed seams or loose pieces from cutting. 

      We realize that retrofitting an existing building can be a challenging project. However, we can confidently say that both the improved comfort and eliminating sweating/condensation is absolutely worth it!

      We have thousands of customers who have installed a radiant barrier in their building and they are consistently amazed at what a difference it makes. 

      We also offer REAL customer support/technical advice with real people. We are NOT here just to SELL you something. We are here to SERVE you!!  If you need help planning or installing your project, please contact our experts. It’s best to send a few pictures and a short summary of your questions. Then, our experts will call you back to discuss solutions for your building.

      STEP 5*

      *This step is optional INTERIOR FINISH: You can leave the interior layer of BlueTex™ exposed (regardless of if you're using the foil finish or the white finish) and the install will be done. If you want a completely finished look however, you can cover the BlueTex™ with just about anything for an interior finish! Depending on your application and what you use the building for, the most common interior finishes are OSB, plywood, tongue and groove or drywall to secure shelving, signage, racks, etc.
