 UPVC doors, made of a heat-resistant plastic, still experience some expansion when exposed to sunlight or high temperatures. The absorption of heat from sunlight causes the molecules in the door to move more vigorously, increasing their kinetic energy. Consequently, the molecules push against each other, leading to slight expansion in the door's dimensions, such as length, width, or height. In simpler terms, as the temperature rises, UPVC doors expand. In most cases, when you leave y …
