Isover Duplex Barrier Roll 40m X 1.5m

Product Code

Vario is an intelligent membrane, designed to adapt to the climate and protect your building, inside and out. It’s also designed with an uncompromising commitment to superior airtightness. Vario will improve your BER (building energy rating), save money, increase comfort and help to combat climate change.
Vario meets and exceeds industry standards, while making a substantial contribution to your BER and environmental footprint. Developed in Germany and available exclusively from ISOVER, Vario membrane is as sophisticated as human skin - altering its structure according to relative humidity.

Vario vapour control membrane offers superior performance, facilitating the drying of the building structure whilst delivering superior levels of airtightness within the building envelope. Just how good is it? Vario’s performance is truly outstanding, it has an excellent variable sd-value: it diffuses 25 times more moisture in summer than the structure absorbs during winter.


Vario features exceptional tear strength, tensile strength three times stronger than polythene, and less likely to be damaged during installation.
Vario is supplied in roll dimensions compatible with modern construction methods, easy and accurate cutting and installation is possible due to markings printed 0n the membrane.
Vario features UV protection for longer shelf life - and for protection during construction where structures are exposed to the sun.
Vario is storm tested up to 150km.
The Vario system is patented worldwide.
