Demilec APX is a revolutionary new open cell spray foam that can be sprayed in attics and crawl spaces without an ignition barrier or coating. Demilec APX is one of the few products that is compliant with the stringent test requirements of the International Code Council, without the use of additional fire protection products. Additionally, Demilec APX provides all of the traditional benefits you expect from spray foam including air sealing, lowering heating and cooling bills, helping reduce dust and allergens and contributing to a quieter indoor environment.

Just wanted to express our thanks for the wonderful work that you did on the addition to our home. The work was done timely, on budget, and of high quality.
