Short answer
Drilling holes in a PVC frame spoils its look and can damage its waterproofing. A hook-and-loop insect screen removes this problem completely.
Why hook-and-loop tape?
- No holes: No drill or screws needed.
- Quick: If the size is ready, it goes on in a few minutes.
- Removable: To clean the filter, just peel it off the tape.
- Flexible: It can be applied on any line that does not stop the sash opening.
Made to measure: hook-and-loop or roll
