SEALECTION® 500 is an insulation breakthrough. Spray-applied as a liquid, it expands within seconds to 120 times its volume to fill every nook and cranny providing superior energy efficiency and improved indoor air quality by eliminating air movement through walls. SEALECTION® 500 is a non-toxic spray foam.


Based in renewable natural resources, SEALECTION Agribalance® creates more energy-efficient buildings by expanding to seal cracks, gaps and voids in attics, walls and ceilings. As a result, builders and owners can use smaller, more energy-efficient heating and cooling units to achieve the same level of comfort.


HEATLOK SOY®, a closed cell Spray Polyurethane Foam Insulation uniquely recycles plastic waste into a Rigid Spray Polyurethane Foam. HEATLOK SOY® can reduce excess waste and energy consumption in buildings by up to 50%. Excellent for use in areas where relative humidity levels exceed 55%.
