This 100mm Unilin SR/CW Phenolic Partial Fill Insulation Board is the go-to option for meeting building regulation U-Values whilst maintaining a protective residual cavity against wind-driven rain. Partial fill masonry walls remain the standard construction approach for period properties, and this 100mm SR/CW phenolic insulation delivers an effective answer when you need improved U-Values.
The outstanding performance-to-thickness balance of 100mm SR/CW cavity wall insulation makes it easy to reach impressive U-Values in traditional buildings without making walls substantially thicker. Using 100mm SR/CW lets you keep the residual cavity, which acts as a reliable defence against moisture ingress.
