We spray both open and closed cell spray foam insulation Open cell foams are softer, more flexible, and more diffusible than closed cell foams. Open cell foams are excellent air barriers and are highly recommended for sound attenuation. Open cell foams are less expensive than closed cell foams due to their light densities. Closed cell foams are superior insulators and vapor barriers. Due to the light weight to strength ratio of closed cell foams, structural integrity of the building is increased. Closed cell foams exhibit higher insulation properties and greater compression strength than open cell foams. Examples of where we typically spray: Existing Attics Remodels and Add-Ons New Home Construction Metal Buildings Other traditional forms of insulation also available.
