• Very durable vapor barrier that increases the long-term efficiency of the fibrous insulation
• Prevents air infiltration
• A double strapping system will allow installing all electric supplies without ever perforating the insulation.
• Also save a lot of time to the electricians

Walls

1. Be sure the fiberglass is perfectly placed between the studs.
2. Staple (FfmF), (FBF), or (FBWP) to the stud white side against the fiberglass (aluminum side inward) every 16" c/c. Do not overlap the material.
3. Seal the seams with aluminum tape.

1. Same installation as the walls, you can install insulation and strapping first. Insulation can support the attic insulation. Just install the fibrous insulation over the insulation between the rafters.
