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 an 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 reflect radiant heat before it enters the interior of the building.
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 and don't feel like we give you enough information in these directions, please email us pictures and/or drawings and we will be glad to help you.
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 tabs up and facing the OUTSIDE of the building.
First, you will need to decide which method you want to use to attach the BlueTex™ insulation to the metal framing. Self-tapping screws with nylon washers are the most popular option or you can use the same screws for attaching the exterior metal panels. Another option is to use a high-temperature rated heavy duty double sided tape. *See notes below for other methods. Remember, you can easily cover the screws with our matching tape to make them disappear.
Continue with this around the entire perimeter of the building until you're done with the first run. Let the tape tabs fold back into the inside of the building for now so they're easier to grab later.
*DO NOT PEEL OFF THE PAPER TAB YET* This will be done AFTER you install the next run above it.
*Notes: Here are a few other tips on how you can attach BlueTex™ to metal framing:
- Double Sided Tape – There are many heavy-duty high temperature resistant tapes on the market. Many customers have used this method successfully with just a few self tapping screws on the tops of the walls and the bottom of the roof for reinforcement.
- Wood Strips - Attach wood strips to metal and then staple the BlueTex to the wood. You can use strips of OSB, plywood, or 1x2”s. Typically, the wood strips are attached to the metal using self tapping screws. The wood strips can be run vertically or horizontally, it does not matter and will not affect the outcome of how the product works. One install method for taller building is to install wood strips horizontally, and then run BlueTex vertically (up and down) by stapling it to the wood, kind of similar to how wall paper is installed.
- Come up with an idea! If you have an idea you think might work that we haven't suggested here, feel free to send us a couple of photos and some basic details of your building and we're glad to offer our opinion and suggestions for your install!
Note: When using either the Foil/Foil or the Foil/White for retrofit applications. On the Foil/Foil style, the tape tabs can face either in or out, depending on how you want to install it. If you face it inward, we'd recommend you tape the seam for the cleanest seam.
For Foil/White style with the white facing in, the tab *must* face outward to properly seam the insulation.
FINISH WALLS: Move up to the second run. Start by positioning the bottom of the second piece so that it is butted up against the top edge of the bottom piece.
Before you attach the insulation into the metal studs, pull it tight across the wall to make sure the seam between pieces is tight and level. Once it's straight, attach it along the bottom of the piece of insulation, just above the seam to secure it all in place. Then secure it in a few (2 - 3) places across the 4 foot span, all the way up the metal frame.
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.
THE ROOFLINE: Keep running the insulation up the wall and stop continue onto the bottom of the roofline. Fasten/attach securely along the way, remembering to keep it as tight as possible for the best finished look.
Roof Ridge: Overlap the insulation 6” on the ridge of the roof and use tape to secure it.
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. Tape is also a good way to cover up any cap nails or other fastener heads.
*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 or drywall to secure shelving, signage, racks, etc.
