Bradford Enviroseal CW is the commercial weight Class 4 vapour permeable wall wrap: a higher GSM triple layer spun bond with more tear and puncture resistance than the RW grades, while still being light to handle.
Where the extra weight pays
Commercial walls stand wrapped longer, take more traffic from other trades, and sit higher in the wind. The failure mode is almost always mechanical damage before cladding, not a performance shortfall. A tougher membrane survives that stage, which is the practical reason to specify CW over the lighter grades.
Two options
CW Wall Wrap and CW-IT with integrated tape, both 1500 mm x 50 m covering 75 m². The IT version carries its own tape strip, which speeds up sealing and takes one consumable off the site list.
Still a breather
Class 4 permeability, so the wall can dry outward while the membrane blocks liquid water and draughts once taped and sealed. Non-reflective, so no air gap is required in front of it.
Suitable for BAL 12.5 through to Flame Zone when installed to specification. Sizes and CSR product codes are in the table below.
