FOAMETIX® offers both open and closed cell spray-applied insulation systems. 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.
