Huntsman Broadens its SPF Product Range for Unventilated Attics

Huntsman Building Solutions has added a new spray polyurethane foam product to its Icynene portfolio. Icynene Xpress 55 is an open-cell SPF insulation designed for use in unventilated attics and crawl spaces.

Huntsman's low-density system is an Appendix X compliant product with an elevated service and technical support package. It doesn't require an ignition barrier for utilities use and exceeds International Building Code fire test requirements. The insulation stops flame propagation once removed from spray foam.

It has good adhesion to a wide range of substrates and layers. The 0.5-pound spray foam has R-values of R-3.7 at 1" and R-13 at 3.5". It also reduces outside noise and pollution while not deteriorating or decomposing.
