Bradford Enviroseal® CW Wall Wrap
Bradford Enviroseal CW Wall Wrap is a light wall duty, Class 4 vapour-permeable wall wrap, suitable for BAL fire regions. The triple-layer spun bond membrane helps manage condensation by letting water vapour escape, while adding a tough, lightweight layer to the exterior side of the frame. Short-term weather cover can let internal trades commence work before external cladding is installed.
With a slightly higher GSM (grams per square metre) than Enviroseal RW Plus, it adds extra robustness for commercial facades and larger projects, yet remains easy to handle on site. Compatible with brick veneer, timber or steel framing, fibre-cement cladding and AAC (autoclaved aerated concrete).
Features and Benefits
Bradford Enviroseal CW helps keep the wall dry by letting water vapour escape, supporting bulk-insulation performance and reducing draughts for better comfort and efficiency. When laps and penetrations are taped and sealed, the membrane forms a continuous air and water barrier that helps block moisture and draughts during construction, allowing internal trades to rough-in before cladding, and continues to protect behind the facade once the wall is clad. The higher-GSM weight improves tear and puncture resistance and reduces wind flutter while staying easy to handle, and the printed 150 mm lap line keeps overlaps neat.
