For a new metal frame building the basic application is to wrap the metal frame on the exterior with the reflective foil facing outward. Then create a required airspace between the foil and the exterior surface (metal, wood, siding etc.) using some type of girt or hat channel.
Below is the BASIC install guide for smaller metal buildings like garages, sheds, barns, mini-storage, etc. Because we know there are many variations for these type buildings, these instructions are meant to be a general guide that can be tweaked or adjusted to apply to all. However, if you have a specific question on how to use BlueTex™ in your building contact us. If you have pictures and/or drawings, you can send those to us too.
*For larger non-conditioned or semi-conditioned building using red Iron steel construction contact us here.
How do you attach BlueTex™ to metal framing? You are basically going to WRAP the metal frame with the BlueTex™ Insulation. So, you need a way for the BlueTex™ to stay on the metal just long enough until you install hat channels (later on in construction) which will secure the BlueTex™ to the metal frame. We suggest you use either double sided tape or use self-tapping screws with a wide head to attach the insulation.
A self-tapping screw is a screw that taps its own hole as it is driven into the material.
WRAP IT: Run BlueTex™ Insulation along the bottom edge of building. Put the tape tab on the top inside against the framing with the peel off paper facing towards the outside. *DO NOT PEEL OFF THE PAPER TAB YET.*
Use double-sided tape or pan-head screws to attach BlueTex™ to the metal frame while keeping it tight. If using the tape, just remember you're not looking for a permanent seal, you just need it to stay in place long enough to get the exterior sheathing attached. When you're putting the BlueTex™ on, you can even wrap it around the corners and continue down next side. If your roll ends, it’s best to cut at edge of the framing, and then start new piece a few inches back to keep going.
KEEP GOING: Install the next run above the first run. *DO NOT REMOVE THE PAPER BACKING ON THE TAPE EDGE YET!* Attach the top ¾ of the second run. For now, DO NOT staple/attach the bottom 12”. Next, lift up the bottom 12” of your second run and begin to remove the tape tab's paper backing, while you're attaching the second run to the tape edge. Gently press on the tape seam from inside to secure the seam.
FINISH WRAPPING THE WALLS: At this point you want to continue with all the walls. Once you're done with the walls, move on to the roofline.
DO THE ROOF: Start at the bottom edge and work up toward the ridge, using the same technique in steps 1 & 2 for the walls.
Roof Ridge: Overlap the insulation 6” on the ridge of the roof.
Roof Edge: Run BlueTex™ insulation 3" to 4” over the edge of the roof and onto both the side walls and gable ends. Then, screw or tape the insulation onto the frame. If needed, use tape to secure the edges.
This next step is optional and it will not change the reflectivity or performance at all, but it looks nice and some people prefer to do it. Tape the foil seams on the outside. This will “clean up” the installation if you have any loose flaps, edges, seams, etc.
The main benefit from taping the seams is that it will reduce the possibility of moisture or condensation from occurring on the inside of the building at the seams, which if it did form, would be minimal, thus the reason this is an optional step.
INSTALL HORIZONTAL HAT CHANNELS OR GIRTS: Use metal hat channels (these are typically installed 2' to 4’ apart from one another) on the exterior, over the BlueTex™ insulation.
We suggest you check the manufacturers recommendations for the metal/siding/etc. that you're using on your building. This will create the required airspace for a radiant barrier to work between the metal skin and the reflective foil layer on the BlueTex™.
INSTALL EXTERIOR CLADDING (METAL / SIDING): Finish the install by adding metal, wood or siding onto the girts to finish your outer layer or “cladding" using the screws recommended by the metal manufacturer.
Then, finish with any trim pieces on your corners, the ridge, around the doors, windows etc.
