The product is not intended to be shortened. It can be adjusted for windows from 76 to 137 cm by sliding. Adjustment is probably still possible with manual labour. However, I would choose a different product for this case, which has to be cut to fit the window anyway.

In the pictures you can see the min/max dimensions of the product. The width can only be shortened by hand with a hacksaw... I hadn't studied this in detail and had to shorten it to 40cm. But think carefully about where to shorten which side and how... :)

Hello, if I remember correctly, this is not possible. I believe the smallest size is 80x80 cm. But it should be described on the Tesa website.
