Demilec Spray Foam Insulation for Unvented Attics

Demilec’s Sealection 500 open-cell spray foam insulation is now third-party approved for use in unvented attics without the need to apply a secondary ignition barrier. In addition to labor savings for installers, the material is designed to help homeowners save money by reducing heating and cooling costs by up to 50%. The Sealection 500 formula expands to 120 times its liquid volume to insulate and seal all cracks, gaps, and joints with a single application, at an R-value of 3.81 for 1 inch. Forumlated without CFCs, HCFCs, or ozone-depleting chemicals, Sealection 500 will retain its shape and half-pound density over time without settling or compacting.
