Tips for choosing window seals

1. Smell with nose. Use your nose to smell for any peculiar smell. Normal PVC material will have a mellow smell, which is almost invisible.

2. Look at the appearance of the profile and the sealing strip. Wrap the sealing strip on the profile as tightly as possible, and leave it under high temperature (roof or full sunlight) for a period of time to see if the surface of the profile and the contact surface of the sealing strip will be stained and discolored, and whether the dust on the surface of the sealing strip will appear. Yellow oozing oil, whether the hands are dirty.

3. Look at the filler for window seals. Regarding some relatively cheap sealing strips, there are many fillers and the appearance will not be very shiny, which is not desirable.
