Demilec APX® 1.2

A Revolutionary New Standard for Fire Safety

Demilec APX® 1.2 is a revolutionary, open-cell spray foam insulation applied in attics and crawl spaces. It is compliant with the stringent fire test requirements of the International Building Code, and can be used in attics and crawlspaces without additional fire protection. Demilec APX 1.2 has an R-value of 3.7 at 1 inch, and is a half-pound density foam. In case of a fire, once the flame is removed from the spray foam insulation, the insulation will not propagate a flame. This superior fire performance eliminates the need for additional protection materials and provides a new standard for fire safety.
