Head Metal SK is a breathable separation layer for ventilated and unventilated steep roofs with metal roofing. The 8 mm thick polypropylene-mono filament sheets (tangled thread mat) assures a constant Rear-ventilation for the roofing material reliably prevents the build-up of condensate and thereby corrosion of the
roofing. The sheet functions as a drainage layer and prevents moisture accumulation on the underside of the metal, as the condensate is drained off to the eaves.
The residual moisture in the boarding and rafters is drained to the exterior through the highly vapour-permeable structure.
The noise level is reduced by up to 14 dB(A) through the use of Head Metall
SK The adhesive tape applied on both sides enables an economically optimal and wind-proof result. Head Metal SK is a suitable separation layer for all convention materials on metal roofs and metal facades: e.g. Titanium zinc, stainless steel, aluminium, copper and galvanised steel.
