Applications

K-Roc® Rainscreen Slab for rainscreen applications

Custom 100mm rainscreen façade systems support numerous construction possibilities, combining different materials with various attachment and support methods for external cladding. When fixings and supports penetrate the insulation to reach the structure, thermal bridges form, affecting overall thermal performance. Thermal isolators can reduce bridging effects, though the selection and positioning of fixings and supports influence heat transfer through the assembly and impact U-value calculations.
