Question about tesa Insect screen COMFORT for windows, with Velcro tape, self-adhesive, without drilling

I would rather not try it, as I can't imagine that it will hold well (if at all) at the connection point due to the tension.

The net is attached with self-adhesive Velcro tape. It would work but you would have a 1.5 cm wide strip where the connection is or you would make the connection differently. Since the Velcro tape is stuck to the window frame, you can build up good pressure when attaching the net to press the net into the Velcro holder. If the tape hangs in the air, it will be difficult to press the net into the Velcro.
