Joist tape

Gelbrot joist tape lays the foundation for professional drainage when sealing window sills. Thanks to its material composition, it is able to flexibly compensate for any unevenness and thus decouples adjacent building materials from each other. Contact between the materials, which leads to long-term wear, is thus prevented. In addition, the joist tape's noise reduction effect has a soundproofing effect that minimises wind noise to a comfortable level. The tape is 100% bitumen-free and scores with its highly flexible and crack-bridging properties as well as highcompression hardness. It is extremely weather-resistant and prevents the sealing from being worn down by UV radiation or frost. As opposed to bitumen-based seals, wear and tear from outside water pressure is just half as high.

Watertight window sills are essential for a healthy moisture balance within your home. As an interface between external weather conditions and the inside of your house, the window is prone to absorbing water if the seal is not clean.

Damp walls can cause significant damage to the masonry and, in the worst case, lead to the formation of stubborn mould.

Proper drainage of window sills can avoid both annoying problems and unnecessary costs.

Sealing prevents water from penetrating into the masonry and allows it to drain at an optimal angle.
