Carlisle is dedicated to providing the easy-to-use products, education and technical support expected from an industry leader. The SealTite PRO spray polyurethane foam (SPF) products firmly place Carlisle at the forefront of SPF manufacturers in North America. SPF insulation is one of the most innovative and versatile developments in construction and insulation technology. In fact, it's fast becoming the insulation material of choice for builders, architects and homeowners alike. Designed for use in residential, commercial, and industrial applications, SPF is superior to other forms of insulating materials such as fiberglass, cellulose or other loose fill products. Our complete line of energy-efficient spray foam insulation products is designed to provide optimal insulation while stopping air leakage and infiltration from taking place. Additionally, spray foam may also act as a vapor barrier.
