Cost-efficiency, smooth laying and unique aesthetics – these are the requirements of modern architecture against high insulated, ventilated façades. The symmetrical cladding is an innovative façade system developed by Rathscheck, which corresponds with these requirements and defines the natural slate façade completely new.Owing to the low square meter weight the symmetrical cladding is ideal for façade design of big building bodies, where high cost-efficiency is essentialThe natural slate stones will be suspended simply with stainless steel clips into an aluminium substructure. The system is construed in a manner, that thermal expansions will be absorbed. Any slate forms up to a size of 60 x 60 cm with only 1 cm thickness allow the perfect adjustment to the building geometry.Three natural slate colours (blue-grey, polar green and dark green) in different surfaces (natural split and polished) of the brands InterSIN® and ColorSIN® offer the designers freedom for extravagant façade designs.
