Metl-Span’s ThermalSafe® panel is the latest development in fire resistant wall construction technology.

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 panel has superior structural characteristics and span capability. Metl-Span has created this panel to achieve a one-, two- or three-hour fire resistance rating under the most demanding condtions. In additon 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® fire resistant insulated panels are ideal for industrial buildings such as manufacturing plants, auxillary buildings at refineries, and other at-risk for fire building installations. Warehouses of all types are excellent structures for mineral wool panels – 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 mutliple steps associated with installation of concreate 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® 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 archieved with ThermalSafe® 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.

  • Based on TS panel with 26 Ga. exterior & 26 Ga. interior face (min Fy = 33 ksi) for single span condition.
  • Allowable span is the lowest value of panel bending strength, shear strength, deflection limit and connection strength.
  • The spans based on panel stress and deflection design criteria are derived from ASTM E-72 structural testing. The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively, and deflection limitation of L/240.
  • The connection strengths are derived from ASTM E-72 structural testing and the allowable loads are calculated with a factor of safety of 2.5.
  • Based on attachment with 14 Ga. steel girt with fastener spacing 3″-18″-18″-3″ across panel width.
  • The structural capacity of the girts are not considered and must be examined independently.
