Alternate Method for Repairing / Covering Old, Torn Wall Insulation in

If your building has old, damaged, or deteriorating insulation, BlueTex™ Pro provides an effective solution for covering it while creating a clean, bright, and durable interior finish.

Engineered for superior performance, BlueTex™ Pro is tear-proof, puncture-resistant, and easy to maintain—offering a significant upgrade over traditional vinyl-faced insulation. In fact, it is more durable than the original insulation facing found in most metal buildings. The key advantage of this installation method is that you don’t need to remove the existing insulation; BlueTex™ can be installed directly over it.

If you’d like to evaluate the product before making a larger purchase, we recommend ordering a Cover/Repair Insulation Sample Box.

This is a sample box of larger materials to test and try out for use in a Cover/Repair Install where the girts are still visible.

A main benefit of the sample box is that you can show tenants/owners/management/etc. how this system works, and preview it on their building before committing to a large order.

The full price of the sample kit is redeemable toward any future order over $500, so it's basically free to try!

There are two primary methods for covering old warehouse wall insulation, with the preferred approach being an interior installation inside the wall girts. This guide offers and alternative option to cover your wall girts inside of the building, encapsulating everything behind a layer of BlueTex™.

If you have any questions about this installation method, feel free to email us with pictures of your building and your specific goals. Our team will be happy to recommend the best solution for repairing or covering your old, damaged, or dirty metal building insulation.

Supplies Needed for Installation

Installing Your Insulation Cover Over the Wall Girts

This installation is done across the face of the walls, fastened to the girts (horizontal wall supports), from the inside of the building, without removing the exterior wall screws on the outside of the building. If you are looking for an option to tuck the insulation behind the wall girts, see below at the bottom of this page.

You can use multiple pieces of BlueTex™ over the wall cavities, or one single piece for the entire height of the wall. Whether you have 1 piece or 100 pieces, it will have no impact on how well it's going to work.
The building has horizontal supports that you can screw the BlueTex™ into.
BlueTex™ will hang down like a curtain during installation, so you can easily screw it into the girts all the way down the walls to the floor.

Step 1: Start at the top of the wall, or the top most girt you plan to cover.

Start by measuring the height from the top of the wall down to the floor.
Cut a piece of BlueTex™ off your roll to the height measured, plus an extra 2"-4".
Hold your BlueTex™ up to top of the wall and secure the BlueTex™ to the frame by screwing it into the metal, allowing the BlueTex™ to be secured at the top and hanging down to the floor (or the next girt). Optional: use an aluminum term bar to hold the insulation against the metal, cinching your BlueTex™ between the frame and the bar.
If you are going from the top of the wall down to the floor, you should use a screw every 12" (4 total for the 50" wide or 5 total for the 62" wide) for the top of the wall, since this is holding the whole piece.
If you're just doing a small section (maybe the top of the walls down to a different finish, use about 3 screws to secure the top piece, like this:

Step 2: Secure your BlueTex™ to the next girt below

Move down to the next horizontal girt support and have a helper pull the BlueTex™ tight.
Screw the BlueTex™ into the girts, spacing your screws about 2' apart (so 3 screws) and keeping the insulation pulled taught so you don't have any ripples.

Step 3: Continue moving down the wall until you reach the floor

There are a couple of ways to secure your BlueTex™ at the floor. Choose one of the options below that works best for your building.

Option #1 - Tuck BlueTex™ insulation between the old insulation and L bracket.
You might have to cut the facing if your original insulation was taped to the L-bracket.

Cut BlueTex™ straight for bottom edge.
Use drywall taping knife or 6” putty knife to push BlueTex™ in between the old insulation and your L-bracket.
Re-use screws from outside to purlins to secure; the screws should line up.
OPTIONAL: Use a thin piece of metal or something like a coat hanger to line up the screw holes if needed. Push from outside and get help putting through original holes. Once one is in, the rest should line up easily.

Option #2 - Push BlueTex™ insulation ON TO existing screws through the floor L-bracket.

If you have screws coming through the L-brackets you should be able to use our insulation washers and push on to secure.
A ½" deep socket works great and use either a hammer to tap on or if you have a hammer drill with hammer only or chisel mode works great to push it on.

Option #3 - Screw BlueTex™ insulation into metal panel rib cavities.

This is similar to the push on screw method except you use our ¾" self-drilling screws and insulation washers to secure the BlueTex™ to the bottom L-bracket.
The KEY here is you can only put the screws where the ribs are in your panel. Otherwise, the screws will penetrate the exterior metal.
Depending on your metal panel type the ribs are usually 9-12 inches apart. The good thing is they are very consistent, so double check the center to center rib distance on the outside of building.
Cut into the old insulation to find a rib, or use a screwdriver to poke through the insulation and find the center of a rib. Then, you can precisely make marks on the L-bracket (or ground) for where the screws will go.

Step 4: Repeat Steps 1-3

Once your first piece is installed from ceiling (or whatever height you're going to) to the floor, time to do the next column.

Align your BlueTex™ at the top of the wall so that it overlaps the previous piece by about 1".
Secure your BlueTex™ to the top of the wall and continue moving down the wall as described in Steps 2 -3 until you reach the floor.
Repeat this until the entire wall has been covered.

Step 5: Seal Your Seams

Once the wall has been covered up, it's time to seal your vertical seams with the 3" wide white vapor barrier seam tape. It's important to press the tape firmly so that it can bond well to the BlueTex™ to permanently seal the seam.

Cut off a few feet of tape at a time and hold over your seams.
Press it firmly onto your seams - the better you press it, the better it will bond!

That's it! You're all done now and you've covered up your old wall insulation with a bright layer of BlueTex™.
