Common Myths About Aluminium Window and Door Profile Thickness
Many buyers focus too much on profile thickness when choosing Aluminium Windows or Aluminium Doors. This article clarifies three common misunderstandings.
1. Using Thickness as the Only Selling Point
China’s 2021 national standard requires at least 1.8mm thickness for thermal break Aluminium Window profiles. Some manufacturers now use 3.0mm thickness as their main selling point. For most home balcony enclosures, 1.8mm Aluminium Door/Window profiles work well. Thicker walls don’t always mean better performance.
2. Does Thicker Mean Safer?
Aluminium Window and Door safety depends on multiple factors. Profile thickness is just one part. The design matters – like cavity structures and load-bearing capacity. Production quality matters – like raw materials and hardware. Installation matters – like proper fixing methods. Commercial And Household Glass quality also impacts safety.
3. Does Thicker Mean Better Insulation?
For balcony enclosures, 70% of thermal insulation performance comes from Commercial And Household Glass. Glass covers the largest area in Aluminium Windows. Choosing Low-E or double-glazed glass improves insulation more than thicker profiles.
