This is a perfectly natural element of the material and absolutely nothing to be concerned about but it can cause temporary problems and difficulty with opening, closing or locking your windows and doors.
What to do if you experience these problems
Should you need to intervene, you can cool down your uPVC doors/windows by spraying the outside with water, by patting it down with a cold, damp cloth or placing a fan on the problem area. This will help the material to shrink back down to size so that it’s once again within its normal working parameters.
Normally as the air temperature cools in the evenings or overnight the material will shrink back on its own.
