Basic Use: Designed for use in exposed wood framing, below panel deck roof systems and other special constructions where a 25 Flame Spread rating (Class A, Class 1) for exposed applications is required. The extended flange permits use in applications where a wider flange is required.

Benefits: CertaPro Extended Flange Batts deliver thermal performance that saves energy and helps control building operating costs. The excellent acoustical properties improve sound control performance in commercial panel decks. The product resists fungal growth and will not rot or deteriorate. CertaPro Thermal Extended Flange Batts are lightweight and will not settle or sag.

The FSK- and white PSK-faced products reduce lighting requirements when exposed, due to their light-reflective surfaces. The black PSK-faced product is light absorbing for low light reflection applications. The low permeance facings are also effective in resisting water vapor transmission.
