Quadratische Schindeln

Fully supported zinc cladding composed of elZinc Square tiles 400 x 400mm. The tiles are made of elZinc titanium zinc, 0,65 or 0,7mm thick rolled to EN988 and ASTM B69-13.

Centre to centre joint width is 342mm. Cladding weight is 7kgs/m2 with 0,7mm thick tiles.

The tiles are fixed directly to the wooden substrate (softwood boarding or plywood or OSB sheathing) using three stainless A2 grade fasteners. For buildings that require a non-combustible substrate for the zinc, trapezoidal metal sheet panels are used as a substitute for the wooden sheathing / boarding.

Façade application: The cladding is normally rear-vented behind the supporting sheathing / boarding with a ventilating space of at least 20mm (some countries require more). A simple breather membrane is normally installed between the zinc and the substrate to act as a separating layer. 

Roofing application: The roof is either ventilated with a ventilating space of between 50 and 100mm (depending on rafter length) under the substrate, or installed in an unventilated (warm) roof design which includes suitable methods for condensation control. A structural underlay (and draining membrane) is often required under the zinc to ensure air circulation to its underside.
