Protan Waterproofing Membrane for wetrooms, top membrane
This solution has a very low profile height, and is suitable for both renovated and new buildings. The top membrane is glued onto a stable surface just below the tiles or slabs. This is a typical solution for the renovation of wetrooms, as it avoids drilling up the old concrete.
Byggebransjens våtromsnorm, BVN, (the building industry's wetroom standard) is a voluntary standard for the construction of both new and renovated wetrooms. A training course is required as the qualification for undertaking construction work according to this standard, which sets stricter requirements than the technical regulations in planning and building legislation.
Protan top membranes present several advantages
- Even thickness of 1.5 mm
- Good elongation at break
- Documented long lifetime
- Moisture-proof Sd = 20 m
- No waiting time
- Can be laid straight onto the floor - ready for tiling
