AireBarrier Green Spray Sealants from Sealant Technologies, Inc expands during installation to fill cavities, gaps, cracks and penetrations throughout the building envelope. Polysealants help block air infiltration, enhance thermal performance and manage moisture on insulation jobs of all sizes. When these air sealants are sprayed, they create an airtight and moisture-resistant seal using two components that quickly bond to common building substrates for a flexible, long-lasting seal. Using a spray on insulation to bridge the gaps in a home or other type of building can bring significant heating and cooling savings through reduced energy usage which makes them a leading aeroseal technology for the emerging air barrier market.

Air Pneumatic Technology

So what is an air sealant? An air sealant is an elastomeric material that allows for 25% - 50% movement. Sealants are used to fill gaps, to keep water and air at bay, to allow for expansion and contraction of building materials and to enhance aesthetics. Silicone and polyurethane are two popular types of sealants. Despite their common purpose, there are major differences between them.

The primary difference is at the chemical level. Polyurethane is an organic material. Silicone is an inorganic material. The effects of breakdown of silicone and polyurethane depend on the sealant’s chemical makeup.
