Frequently Asked Questions

R-value is the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.

2 lb is R6/inch

1/2 lb is R3.7/inch

Spray foam insulation is not affected by wind and/or pressure changes whereas batt and poly allow air infiltration under these conditions.

2 lb (closed cell) is more dense and provides a higher R-value. After 2 inches of 2 lb foam, it is a vapor barrier. 2 lb foam also is rigid and adds to the racking strength of the structure. (Racking strength pertains to the structures ability to withstand wind load).
1/2 lb (open cell) is less dense while still providing good R-value. While poly is still required by code, 1/2 lb is an air barrier - meaning the air barrier is still intact after staples and screws in the poly.

Most brands of foam are essentially the same. They all have similar R-values, are air and vapor barrier materials, and significantly increase the “tightness” of the building envelope (it doesn’t leak air).
However, our 2lb spray foam contains a revolutionary new blowing agent, which is the ingredient in spray foam that gives it such a high R-value. The blowing agent in our spray foam is called Solstice. It has a Global Warming Potential (GWP) of 1. All other spray foam manufacturers in Canada use the 245fa blowing agent which has a GWP of nearly 1000.
