Applications

K-Roc® Rainscreen Slab for rainscreen applications

Custom-designed 30mm rainscreen façade systems accommodate numerous system configurations, combining various materials with different methods for securing and supporting external cladding to the structural wall. When fixings and supports penetrate the insulation layer to reach the structure, they create thermal bridges that can reduce overall façade thermal performance. Thermal isolators can help minimise these effects, though the choice and positioning of fixings and supports may increase heat transfer through the façade assembly, affecting the U-value calculation.
