Sprayed Polyurethane Foam
Demilec USA offers both open as well as closed cell sprayed polyurethane foams for both residential and commercial construction. Our open cell products, Sealection 500 (.5 lbs density) and Sealection Agribalance (.8 lbs density) are water blown products which exceed the government standards for renewable content. Both products provide excellent thermal, air barrier and sound barrier protection.
Both our Heat Lok Soy 200+ and Heat Lok XT closed cell foams can be used in both commercial and residential construction. Due to their closed cell nature they are used in environments not suitable for open cell foams. Cavity wall installations, back of precast, parking garages, etc. are all environments where both Heat Lok Soy 200+ and Heat Lok XT will provide the long term durability, thermal insulation, moisture/vapor barrier as well as air barrier protection required in these environments.
A growing use of the closed cell foam is on the typical cavity wall installation. The typical cavity wall installation includes a spray applied air barrier or sheet applied membrane covered by Dow Blue board. Another method used on installations is to apply the Dow Blue Board directly to the substrate with the seams taped. Neither of these systems can match the monolithic single application of either Heat Lok Soy 200+ or Heat Lok XT. The penetrations around the masonry ties, long term durability of the taping of the seams, cutting around openings etc leave opportunites for heat loss and air penetration etc that are eliminated with the use of a closed cell spray applied polyurethane foam.
