In our store you will find a variety of seals for wooden windows and wooden front doors of different systems. These are also known as "sash rebate seals". The seals are important for effectively sealing the windows against draughts and noise.
These rubber seals are installed in a milled groove with a width of 4 or 5 mm in the window sash. When the window is closed, the window sash is pressed against the window frame using the window handle to ensure complete sealing. The seals ensure that there is no exchange of air or moisture between the inside and outside, which contributes to the energy efficiency of the building.

To find the right seal, the following features are crucial:
Groove width (possibly also check the groove depth)
Rebate height (usually 10 or 12 mm)
Clearance (the distance between the sash and frame)
In the 1960s, wooden windows and doors were still manufactured entirely without seals. At that time, adhesive seals were mainly used to seal leaking windows. At the time, these were a popular solution to stop draughts, as there were no other alternatives to seal windows. Tesa Moll, known from advertising, has been internalized by many hobby craftsmen to this day. Adhesive seals in any form are still used today for leaking wooden windows without a sealing groove (often older box-type windows in old buildings, primarily in Berlin).
Are adhesive seals useful? No, adhesive seals are not recommended for all windows manufactured in accordance with the DIN standard, regardless of whether they are PVC or timber windows with a factory-fitted window seal. Improper use of an adhesive seal can lead to damage or even breakage of the window fittings.
It was not until the mid-1960s that wooden windows were fitted with soft rubber profiles in Germany. Originally, this was only for noise insulation when closing the window (wood on wood). Over time, wooden windows and doors were also manufactured in accordance with DIN standard 18101, which led to standardized dimensions for windows and doors.
