ThermoSeal 500 make homes more energy efficient, quieter, healthier and more comfortable by Spray Foam Polymers
ThermoSeal 500 is the registered trademark of SprayFoamPolymers.com for its .5lb light density, open cell foam insulation.
ThermoSeal 500 is a semi-rigid, totally water blown, .5lb light density polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. ThermoSeal 500 is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal 500 is applied as a liquid spray which expands approximately 100 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal 500 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 500 specification sheet here.
