VAPOUR CONTROL MEMBRANE
VAPOR 225
The VAPOR 225 vapour control membrane is the cost-effective membrane, ensuring high performance and protection against weathering. It is also suitable for installation on uneven and rough supports, which could damage lighter vapour control layers.
VAPOR 225, the most resistant vapour control membrane on the market.
Although the membrane is very thick and resistant, its composition ensures great flexibility in processing without the risk of material wear. The mass per unit area of the membrane provides mechanical strength and protection during construction; VAPOR 225 ranks among the strongest vapour control membranes on the market.
The TT version offers fast installation and professional sealing thanks to the integrated double tape. It is one of the products for which the EPD and LCA environmental declarations have been developed.
