Spray Foam Basement - Fairfax, VA

Monday, May 13th, 2019 by Justin Dobson

Challenge

This homeowner in Fairfax, VA wanted the best insulation possible for their newly framed basement renovation. They were looking for no drafts, great insulation thermal value, and a good sound barrier.

Solution

Comfenergy suggested closed cell foam spray as a solution and the homeowner loved the idea. Closed cell foam spray MUST be used in a subterranian area like a basement below grade. Closed cell foam spray creates a vapor barrier at just one inch of thickness, while open cell allows vapor and air to travel through until there is a thickness of about 5" or more. These walls are now air tight, structurally sound, and have an approximate R20 value.
