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.

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.
