What is ThermoSeal 800?
ThermoSeal 800 is a two component, semi-rigid, totally water blown, .75lb light density polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. Thermoseal 800 requires the use of an “A” component (ISO) and a blended “B” component (RESIN), which contains ZERO ozone depleting blowing agents, catalysts, polyols and fire retarding materials. ThermoSeal 800 is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal 800 is applied as a liquid spray which expands approximately 75 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal 800 fills all building cavities completely, sealing all cracks, crevices, and voids where air loss and in ltration are most common. If needed, excess material is easily trimmed o leaving a surface ready for drywall.
