ThermoSeal MAX Medium Density • Closed Cell Spray Foam Insulation System

What is ThermoSeal MAX?

ThermoSeal MAX is a two component, semi-rigid, medium density, 1.7 lb closed cell polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. Thermoseal MAX 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 MAX is designed for residential, commercial, and industrial building applications to make structures more energy efficient, quieter, healthier and more comfortable. ThermoSeal MAX is applied as a liquid spray and fills all building cavities completely sealing all cracks, crevices, and voids where air loss and inltration are most common.
