Knauf Insulation has launched Rocksilk® RainScreen Cavity Systems, a range of complete tested systems designed to simplify specification and support compliance in cladding and masonry façades. The systems consist of sheathing insulation, fixings, and cavity barriers.

Textbooks overlook a commonly-occurring design consideration that arises where some horizontal and some sloping roofs abut a cavity wall. Consequently, despite construction observing guidelines and regulations, the building suffers wet ingress.
