Foaming Specialist LLC only uses the top of the line closed cell foam. “HEATLOK HFO Pro” is manufactured by Huntsman Building Solutions. This SPF system is quickly taking the market by storm, and is considered to be the best on the market. Also offers an incredible R-7.4 per 1”! Smart SPF HFO High Density Foam is also known to be more environmentally friendly than competing foams.
We prefer closed cell foam as it is much more rigid and stable than open cell foam. Closed cell spray foam is made up of cells that are pressed together, so air and moisture are unable to get inside the foam.
