PVC windows resist water, adapt for humid and coastal areas. Unlike aluminum profile material, they won’t rust or corrode.
PVC windows with double glazing offer low conductivity (U-value ≈ 1.4 W/m²·K), cutting energy consumed 60–65% vs. traditional windows.
PVC windows (U-value 1.30) outperform premium aluminum (U-value 1.70), providing superior insulation and less energy loss.
Steps of manufacturing windows and doors:
1. Cutting / 2. Open Corner Brace Hole / 3. Install Corner Brace / 4. Cleaning Glass / 5. Glass Assembly / 6. Gluing / 7. Test / 8. Packing
