May we introduce: Dichtungsklick!
High-quality real wood blends unobtrusively into old building wooden frames.
The core component is a modern silicone seal, similar to those used in modern windows. The seal can be replaced at any time.
Even with the window open, the strip is barely noticeable.
Thanks to adhesive technology, no drilling is necessary and the window frame is not damaged.
The Dichtungsklick strips are installed and the window is insulated in just a few minutes.

More comfort, less consumption – without changing your windows.
Dichtungsklick is the professional solution for sealing old wooden windows – without any screws or drilling.
Why Dichtungsklick?
Old windows lend an apartment its typical charm – at the same time, they are often drafty and offer little protection against cold, noise, and fine dust. Dichtungsklick was developed precisely for this challenge: a simple and effective solution for retrofitting historic windows with a seal.
