Passive Purple

Passive Purple is the Intelligent Membrane that provides airtightness, vapour control, radon barrier and is even fire proof to Fire Class C – SL, d0 (internal edition) and Fire Class B – S1, d0 (external, retrofit and X edition). It is fast becoming the recognised vcl membrane used worldwide to provide residential and commercial property owners with improved efficiency. It is flexible, watertight and easy to install.

As a rule of thumb you will require 1 brush tin and an airtight tape for every 5 tins of spray that you buy! Our application brush is also designed to make your install seamless!
