Made to measure: hook-and-loop or roll
Short answer
The right size is the most important step for a gap-free fit. By following a few simple rules you can measure without mistakes.
Common mistakes
| Mistake | The right way |
|---|---|
| Measuring the glass | Measure the frame or screen frame where the filter will sit |
| Measuring at one point | Measure at the top, middle and bottom |
| Forgetting the sash | Open and close the sash to check the tape line |
| Leaving no allowance | In the hook-and-loop kit, the filter should overlap the tape |
| Mixing up width and height | Width first (left to right), then height (top to bottom) |
