Wolfin’s new “cellphone block” membrane has been specifically designed to block mobile phone transmissions in and out of sensitive buildings constructed with flat roofs– whilst still acting as a stand-alone waterproofing system.

Wolfin CB has already been installed in prisons and in defence installations.

Most cell-phone blocking systems rely on electronic blocking devices situated in the area. Wolfin CB, on the other hand, prevents transmission through the areas that are traditionally the most difficult to block; the roof. Walls are blocked using metal cladding and the windows are laminated to give an effective block with no ongoing costs.

Wolfin CB is based on Wolfin’s GWSK self-adhesive membrane system that comes complete with its own system of steel profiles and cast-in details.

Wolfin CB will be marketed in Australia by Wolfin Membranes Australia.
