Our NON AQUA anti-condensation barrier solves problems with condensation inside buildings.

Basic information

The NON AQUA anti-condensation barrier is a self-adhesive membrane implemented for roofing during the pressing process.



The use of a coating on the bottom layer of the roofing material retains moisture in a special ‘pocket’ formed in the membrane. As a result, it does not condense and do not damage the materials below the roofing. Moisture is held in the membrane until ambient conditions fall below the dew point. Then the water is evaporated as a component of ordinary moisture.


  • no more dripping from the roof
  • solidity: the barrier is resistant to tearing or spoiling in contrast to standard insulation
  • easy to clean

In order for the anti-condensation barrier to work properly, adequate roof ventilation must be ensured!
