Shelterform™ provides the second layer of insulation and a rigid support system that prevents buckling, denting and insect nesting under the vinyl siding. This combination makes Backerwrap™ the ultimate insulation system on the market today.
The R-Value for a wall system is determined by ASTM C236. the “Guard Hot Box” method, which vary by siding profile:
Double 4” = R 3.3
Double 4.5” = R 3.7
Double 5” = R 3.4
Double 4” Dutch Lap = R 3.6
Double 4.5” Dutch Lap = R 4.0
Double 5” Dutch Lap = R 4.0
Triple 3” = R 3.7
Horizontal 8” = R 3.0
Shelterwrap HD R-Values
1/4” thick = R 1.2
3/8” thick = R 1.6
1/2” thick = R 2.1
3/4” thick = R 3.1
1” thick = R 4.2
R-Values stated above are at
5 degrees F. R-Values actually increase as the temperature
