Between the zinc plus and the insulation the vmzinc breather membrane link to 8 1 vmzinc membrane is fixed with an overlap depending on the pitch. Non vented warm roof build ups as well as on vented cold roof build ups. For a pitch lower than 14º the joints must be taped between 14º 22 there must be an overlap of 200mm just steeper than 22 or unless it changes above 40º there must be an overlap of 150mm. Products typically used are warmfast and thermoseam and the setting out of the fixed sliding clips is to specific manufacture guidelines.

Zinc panels are installed to the prepared deck using fixed sliding clips with plugs and screws specific for warm roofing. All wall cladding should be ventilated. In order to keep the integrity of the roof it is recommended to install vmzinc breather membrane on the cold side of the insulation and a vapour control layer adapted to the internal humidity load of the building on the warm side of the insulation. With this warm roof system vmzinc plus standing seam can be installed on metdeck composite panels without ventilating the underside of the vmzinc plus.
