How we use Thermalrock® B Blanket in steel buildings

On World Steel pre-engineered and structural steel buildings, ROCKWOOL Thermalrock® B Blanket is laid under the metal roof sheeting on the purlins, held by wire mesh and foil where specified – cutting solar heat gain and rain noise while keeping the roof non-combustible. We size the thickness with the roof design, take quantities from the same 3D model as the purlins and sheeting, and ship the insulation with the steel package.

01Specified with the structure – thickness, density and facing matched to the roof, wall and fire design.
02Quantities taken from the same 3D model as the steel, purlins and cladding.
03Packed and shipped with the steel package – one delivery schedule to site.
