Steel or timber deck
This structure is successively covered by:
A vapour control layer with a high water vapour resistance installed with cold or hot glued joints.
Insulation: mineral wool. All insulation materials have to resist a compression strenght of minimum 50kPa (0.5kg/cm²), at a maximum 10% deformation. The insulation must have the necessary approvals for use in warm roof applications.
Between the Zinc PLUS and the insulation, a breather membrane is fixed with an overlap of + 150 mm.
