30 Degree Temperature Barrier
Success Story: Read Here
FoilBuild and FoilTech materials have excellent insulation properties and exhibit respectable R-values. Their affect of blocking radiant heat combined with the insulating properties of the air bubble layer creates a prime temperature barrier.
One should note that ALL R-Values are determined with very specific parameters during a controlled test. Therefore, if there is indeed a claimed R-value, one must match such parameters in the installation to match the desired rating.
FoilBuild RValues
Crawl Space: RValue Est. 16.8
Walls- Post Frame: RValue Est. 19.56
Walls with masonry, RValue Est. 3.7 or better
Concrete Slabs: RValue Est. 1.1
Pipe Wrap: RValue Est. 4
Duct Insulation: RValue Est. 6
Garage Door: RValue Est. 4
Water Heater: RValue Est. 4
Wine Room: RValue Est. 3.7
FoilTech Packaging Grade Performance:
FoilTech can perform as well or better than Styrofoam insulation. It is an excellent replacement product for Styrofoam inserts.
FoilTech Box liner averaged 10 degrees cooler than Styrofoam inserts.
