What is ThermoSeal OCX?

ThermoSeal OCX is a two component, semi-rigid, totally water blown, .5lb light density polyurethane foam insula- tion system which simultaneously insulates and air-seals your building structure. Thermoseal OCX 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 OCX is designed to make homes more energy ecient, quieter, healthier and more comfortable. ThermoSeal OCX is applied as a liquid spray which expands approximately 100 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal OCX 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.
