Covestro L.L.C. has introduced Bayseal OCX, an open-cell spray polyurethane foam insulation.
The company said the product is formulated to meet the requirements of (AC) 377 Appendix X, meeting IBC and IRC requirements for fire resistance without an additional ignition barrier or intumescent coating when applied in service-only attics and crawl spaces.
Bayseal OCX expands in place when applied, Covestro claimed, making it a one-step air seal and insulation. It also complies with the 2012 and 2009 International Energy Conservation Code, the company said, contributing to third-party sustainability programs such as LEED and EnergyStar.
