INTELLO Humidity Variable Intelligent Airtightness System

The INTELLO Humidity Variable Intelligent Airtightness System utilises synthetic membranes for use as a humidity-variable vapour control layer and as part of an air barrier system fitted to the inside face of ceilings and external walls. The INTELLO membranes consist of a polyethylene copolymer with a polypropylene fleece backing. Accessories include adhesive, tapes and penetration seals, which are supplied as part of the system.

The purpose of the system is to reduce air infiltration through the building fabric to reduce heat loss and to control the diffusion of water vapour through the building envelope.
