There are two major types of spray foams available on the market. Both EXY® closed and EXY® open cell spray foam insulation can be used effectively to achieve building energy efficiency and consistent performance. When applied on the interior, open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior. It's important to understand each product and how it works. Contact a professional or certified partners who recommend product for your needs. Or do your own research.
EXY® foam is spray-applied as a liquid and expands within seconds to 30 -150 times its liquid volume, depends of what foam type you chose. The foam adheres directly to the substrate forming a seamless and permanent coverage over and around even the most difficult shapes. This seal provides superior energy efficiency and improved indoor air quality by eliminating air movement. Once in place, EXY® foam maintains its performance for the life of the building. Unlike many conventional insulations, time and temperature changes have no effect on R-value of spray foam insulation.
