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.ThermalSafe NEF

Uses and Applications

ThermalSafe® fire resistant mineral wool panels are ideal for industrial buildings such as manufacturing plants, auxiliary buildings at refineries, and other at-risk for fire building installations.  Warehouses of all types are excellent structures for this fire resistant panel – either where they can be installed as exterior separation walls or as demising walls inside tilt-up warehouses with multiple tenant leased space.

Compare the Features and Benefits

Non-Combustible Core resists high temperatures and will not burn, providing excellent fire resistant qualities.

One-Step Construction process assures rapid completion of the wall system.  Factory fabricated composite panels are attached directly to the supporting structure and multiple steps associated with installation of concrete blocks or numerous layers of gypsum wallboard are eliminated.

Superior Thermal Performance and protection from the elements across the entire wall area is assured with Metl-Span ThermalSafe® fire resistant mineral wool panels.  The advanced mineral wool core provides enhanced insulated values that significantly lower heating and cooling costs.

Reusable Panels can be disassembled, moved and reinstalled rather than having to be demolished, the waste materials disposed of and the walls completely rebuilt.

Better Sound Absorption acoustical properties are achieved with ThermalSafe® fire resistant mineral wool panels compared to foam insulated metal panels.

Aesthetic Profile facing can be combined with Metl-Span CF Light Mesa foam insulated wall panels for consistency in profile, texture and color.
