REFLECTIVE VAPOUR BARRIER SD > 1500 m
BARRIER ALU NET SD1500
BARRIER ALU 1500 is the aluminised vapour barrier characterised by an extraordinary Sd value.
It consists of an aluminium layer, a polyethylene film and a reinforcement grid, it is designed for application on the inner side of the building envelope of timber structures. The membrane and joint have been tested according to ISO/TS 11665-13 for radon gas protection of the entire system.

BARRIER ALU 1500, the vapour barrier that protects you against radon gas.
The BARRIER ALU 1500 vapour barrier membrane strongly limits the passage of water vapour from the hot to the cold side of timber structures, thus protecting them from the problems of interstitial condensation that can undermine the longevity of the structure.
The aluminised surface reflects heat by up to 70% when coupled with a ventilation chamber.
The membrane reduces the permeability of the building's perimeter and foundation structures, while minimising the presence of radon and eliminating health risks. Ideal for vapour flow control in very humid environments such as wellness centres, indoor swimming pools and industrial laundries, in order to safeguard stratigraphy.
