What is ThermoSeal CCX?

ThermoSeal CCX is a two component, semi-rigid, medium density, 2 lb closed cell polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. Thermoseal CCX requires the use of an “A” component (ISO) and a blended “B” component (RESIN), which contains ZERO ozone depleting catalysts, polyols and fire retarding materials. ThermoSeal CCX is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal CCX is applied as a liquid spray which expands approximately 15 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal CCX fills all building cavities completely sealing all cracks, crevices, and voids where air loss and infiltration are most common.
