Selection of UPVC profiles

To choose high-quality plastic-steel doors and windows, you must first understand the PVC profiles used.

PVC profiles are a key factor in determining the quality and grade of plastic-steel windows. High-quality PVC profiles feature a multi-cavity structure designed according to a template, typically with a wall thickness of 2.2/2.5 Mm. The formula contains anti-aging and UV-resistant additives, resulting in a smooth, ivory-white appearance.

Nach einigen Jahren der Nutzung, mid- and low-end profiles will become increasingly yellow, eventually aging, deforming, and becoming brittle. This is due to excessive calcium content in the profile formula or the use of recycled materials. Considering that most homes have large windows (wie geschlossene Balkone) and are common in high-rise buildings, profiles should have a wall thickness greater than 2.5 mm and a three-cavity structure (with an enclosed drainage chamber, an isolation chamber, and a reinforcement chamber) to ensure that the window will not deform for decades. Furthermore, this type of profile is resistant to discoloration and aging.

The above is a detailed introduction to plastic-steel profiles.
