What is the "R" Value? 

 Here at Scranton Spray Foam, we understand that some terminology can be quite confusing. Have no fear, we are here to help. When insulation contractors talk about R-Value, they are referring to “resistance to flow”. In other words; how resistant a type of insulation is to air escaping through. The higher the R-Value, the better the insulation. Although brands of spray foam insulation may differ, the R-Value number will remain constant across insulation brands. In any case, Spray foam is lightyears above traditional fiber glass.
