Metal Roof Deck Section With 7 mm Sheet and 80 mm Rock Wool.

This drawing shows a metal roof deck section with layered construction prepared in AutoCAD files for roof structural detailing. The deck system illustrates a corrugated metal sheet base supporting multiple insulation and protective layers used in modern roof assemblies. The section includes a corrugated steel deck profile that forms the structural base of the roofing system. Above the metal deck, a rigid insulation layer and 80 mm rock wool insulation are installed to improve thermal and acoustic performance. The drawing also shows a 1.5 mm PVC protective membrane placed above the insulation layer, which acts as a waterproof barrier protecting the roof structure from moisture penetration.
