Attach window seal with adhesive backing

The majority of window seals consist of flexible profiles that are inserted unglued into grooves on rebates and window frames. The second group of window seals are flexible adhesive strips that are subsequently glued to frames and in locking notches.

Self-adhesive rubber seals

Flexible plastic profiles adapted to the grooves are used as standard seals on windows. The press shape of the profiles develops durability created by material tension and "jams" itself. The soft, rubbery texture and the window pressure form the sealing and insulating function. When replacing the window seals, identical profile shapes must be fitted mechanically without gluing.

The other way to apply window seals is to stick on insulating tapes. The tapes with a high proportion of rubber mixed with synthetic foam are applied to smooth surfaces that meet one another. Different shapes are available for the different locations and types. In addition to fully elastic solid rubber bands, plastic foams with cavities such as p-shaped profiles or fanned and movable e-shaped profiles can also be used.

Attach additional window seals

  • Self-adhesive sealing tape
  • Degreasing detergent such as dish soap
  • water
  • Microfiber cloth
  • Cotton cloth
  • scissors

1. Clean window frames

Depending on where you want to apply the self-adhesive window seals, you need to ensure that the adhesive surface is clean, free of dust and grease. Wipe the adhesive surface with a degreasing detergent and wipe with clean water.

2. Remove window

If you want to attach a window seal to the hinge side of the window, you must remove the window sash in the same way as for replacing the profile seals in the grooves.

3. Apply seal

Peel off the beginning of the protective film from the back of the self-adhesive window seal and place the adhesive surface in a corner of the frame or the fold.

4th. Gluing process

Continue the adhesive strip on the adhesive surface with one hand and remove the protective film with the other hand. Bit by bit, press the adhesive surface of the strip straight onto the surface with your thumb.

5. Closing test

After completing the first page, do a window closing test. If the locking mechanism does not lock or jam, tape the window seals on all sides.

Tips & Tricks Bear in mind, especially in small rooms, that the waterproofing can be too tight. If all air circulation is suppressed when the windows and doors are closed, this can lead to a lack of oxygen and excessive condensation.
