Replace window seals in parts

Sometimes only individual corners or portions of the window seals are damaged. Not always a complete renewal must be. With careful replacement and gluing of the damaged portions, the tightness and insulation is completely given.

Restore the endless tape

Window seals usually consist of a continuous circulating profile tape. If portions are to be replaced, the continuity must be restored by sticking the bands. Any interruption of the window seal is a potential vulnerability and can massively influence the effect of residual seal. The adhesive may only connect the profile tape to one another and not run into the fastening grooves.

In contrast to the complete replacement of the window seals, partial work is required. With a sharp knife or cutter, the damaged piece must be separated from the remaining tape with clean cuts. The individual pieces that have been cut out can be levered out with a spatula without moving the remaining tape out of the joint. The prerequisite for a successful replacement is the accuracy of fit of the replacement profile pieces.

How to replace window seals
