ThermalSafe® NEF Fastener Fire Resistant Panel

Metl-Span’s ThermalSafe® Non-Exposed Fastener (NEF) mineral wool panel is the latest development in fire resistant wall construction technology and provides a flush appearance.

ThermalSafe® combines advanced panel design with Metl-Span’s sophisticated manufacturing expertise to create a composite panel with a core made from non-combustible structural mineral wool boards that are processed in the factory to maximize compressive strength. The resulting fire rated panel has superior structural characteristics and span capability. Metl-Span has created this mineral wool panel to achieve a one-, two- or three-hour fire resistance rating under the most demanding conditions. In addition to its fire resistance characteristics, the panel provides good thermal performance and protection from the elements. The unique LockGuard® interlocking side joint further enhances the fire resistant performance of the panel with its tongue and groove engagement of the mineral wool core.
