ThermoSeal FG500 is a semi-rigid, totally water blown, .5lb light density highly fire resistant polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. ThermoSeal FG500 is designed to make homes safer, more energy efficient, quieter, healthier and more comfortable. ThermoSeal FG500 is applied as a liquid spray which expands approximately 80 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal FG500 fills all building cavities completely sealing all cracks, crevices, and voids where air loss and infiltration are most common. If needed, excess material is easily trimmed off leaving a surface ready for drywall.Download the ThermoSeal FG500 specification sheet here.
