This 80mm SR/CW Phenolic Partial Fill Insulation Board is engineered to help you meet building regulation U-Values while keeping a residual cavity to guard against wind-driven rain. Partial fill masonry walls remain the standard construction approach for period properties, and 80mm SR/CW phenolic insulation provides an effective route when you need to achieve lower U-Values.
The excellent performance-to-thickness balance of 80mm SR/CW cavity wall insulation makes it possible to reach superior U-Values in period buildings without substantially widening the wall structure. By choosing 80mm SR/CW, you maintain the residual cavity, which acts as a reliable defence against moisture penetration.
