Product Information

Reliable, weather-tested seals

In order to seal aluminium window sills in accordance with RAL regulations, there must be a second sealing level. The slope of this level drains the rainwater, which protects the window sill on the underside from driving rain or condensation. This technology also complies with GEG regulations.

The vapour permeable waterproofing membrane (SD≤0.5) from gelbrot ensures that humidity is dissipated, and it can also be used as avapour barrier .

The waterproofing membrane is self-adhesive on both sides and is attached to the substrate with the help of tried-and-tested Power-Haft technology and, thanks to additional plaster perforations, is absolutely secure.

In order to withstand wind and general weather, the membrane is equipped with a UV stabilizer and is also optimally protected against heavy driving rain.

Thus, the special drainage sealing sheet from gelbrot guarantees controlled water drainage from ungrounded floors , regardless of the weather. Gelbrot's drainage sealing membrane is packed in rolls and is generally available in the following dimensions:

Length in metres 50 50 50 50 50 50 50 50
Width in millimetres 150 180 210 240 280 320 360 400

Due to the different widths, it can be attached to components of different sizes. In addition, the sealing membranes are very thin, and can be easily cut to size from the roll with a cutter knife.
