It has an R – 4.9 per inch which is equal or superior to R-values associated with certain rigid board products. Foam does not settle like zonolite or perlite, and completely fills all the voids in the wall – unlike pre-manufactured insulation inserts.

The higher the R-value, the better the insulation and the more effective it is at stopping heat transfer. Spray foam insulation approximately has R-6, whereas fiberglass insulation has an R-value of between R-3.8 and R-5. In general, fiberglass insulation is less effective at stopping heat transfer than spray foam insulation. This makes spray ...
