White Paper: Multi-layered Walls Weatherproofing for Rear Ventilated Facades by HVG Facades

Rear ventilated facades (RVFs) are gaining in popularity with design and construction professionals. There is growing awareness of the advantages of RVF systems, particularly the extra layers of weather protection they provide to external walls. While understanding of the design principles of RVFs is improving, there is still some confusion as to the relevant weatherproofing requirements and the corresponding testing procedures used to verify compliance. In this whitepaper, we take a closer look at RVF systems, their benefits in modern building design, and outline the key performance requirements and testing procedures relevant to weatherproofing such systems.
