- Variation of temperature and extreme temperatures can cause the seals to shrink.
- Not using high-quality seals will also result in shrinking.

Now, run the tape on the outside so that you can place the windows again. The seal tapes are in the exact size that won’t leave any gaps. Hence, you won’t have to trim them again. Moreover, they have great temperature resistance against harsh weather.
On the other hand, overlap and mold the tapes on the corners of the windows.
