Internal Membranes

The Pro Clima award winning range of airtight membranes includes the best selling and unique  Intello Plus an 'Intelligent' vapour control membrane. This is different from conventional vapour barriers and vapour checks as an 'Intelligent' membrane is designed to become more vapour open if required. The membrane can alter its diffusion resistance depending on the average relative humidity so ensuring that interstitial condensation risk is minimised, with no structural damage from moisture, mould, rot and damp.
