TremLock ThermalRib:

TremLock® ThermalRib™

Insulated Metal Panel Versatile Enough For Use In Multiple Applications

The TremLock ThermalRib is our most popular panel, particularly in cold storage and commercial/industrial applications.  It can be used as an exterior wall, partition wall, liner wall, and ceiling. TremLock ThermalRib’s lined profile provides strength, facilitates foam adhesion and helps minimize natural imperfections in the steel faces. The shallow rib and unique side joint help ensure a high-performance vapor seal.


TremLock ThermalRib panels are designed with a 42” coverage width. Available lengths of 8’-0” to 53’- 0”.  Panel thickness options are 2, 2.5, 3, 4, 5, and 6 inch. Exterior gauge availability of 22, 24, and 26, interior gauge of 26. Both the exterior substrate and interior substrate are Galvalume®, G90, stainless steel. The joint is Green-lock, offset double tongue-and-groove. The core is continuously poured-in-place polyisocyanurate insulating foam. The R-Value is R-8 per inch of thickness (nominal.)
