Protan G Membrane for Wet Rooms

The Protan G membrane is used for wet room walls and floor.Waterproofing helps protect from damages caused due to humidity and seepage.

We recommend the Protan G membrane for wet rooms both for new construction and renovation projects. Protan G membrane is a 1.5 mm thick waterproofing membrane that can be hot air welded, and used both on the floor and walls in the wet zone.

Humidity causes more damage on buildings than anything else. Humidity damage costs home owners and society at large several billion NOK every year. Health problems caused by bacteria and fungus growth in the building materials come in addition to the costs. Small leakages with “insignificant” amounts of water can quickly cause serious damage to the building.
