Product Information

The solution for all standard aluminium window sills

With the practical corner sealing system, all aluminium window sills can be sealed quickly, easily and inexpensively.

Drainage inner corners from gelbrot consist of one piece for left-hand fitting and one piece for right-hand installation. They are 370 x 120 mm in size and have a length dimension printed on them, which enables the system to be easily adjusted.

The prefabricated and precisely fitting corners simplify installation considerably and offer significant time savings.

They are compatible with all standard aluminium window sills and effectively compensate for material expansion caused by heat. Thanks to the specially coordinated, vapour-permeable system, the building connection joints can be ideally ventilated.

To ensure sealing of window sills in accordance with the Building Energy Act , the system from gelbrot forms a second, water-carrying and sloping sealing level. This prevents rain or condensation from penetrating under the window sill and drains the moisture to the outside. In this way, there are no cold bridges under the respective window sill.

High functionality

The drainage inner corners, which you can order with or without self-adhesive, have the best material properties and stand out for their high functionality. They are:

  • Water-resistant
  • Temperature-resistant
  • Alkali-resistant
  • ​UV-resistant
  • Driving rain-proof

The efficient capabilities of the inner corners are rounded off by an appropriate sealing membrane and an insulating wedge.

If you opt for the drainage inner corners with self-adhesive, this saves additional time and work. The use of a special drainage adhesive is recommended for gluing the variant without self-adhesive.
