The UPVC window features a high-quality locking system for enhanced security.
The aluminum reinforcement within the PVC frame ensures durability and smooth operation.
A built-in insect screen is visible, offering protection from bugs while maintaining airflow.
| Feature Comparison | WANJIA Factory Direct | Ordinary Supplier |
|---|---|---|
| Profile Quality | Thickness PVC + full-length steel | Thin wall, easy to deform |
| Hardware | German lock + SS rail | Cheap parts, short lifespan |
| Sealing Performance | Triple seal + double wool strip | Single wool, leaks easily |
| Glass Configuration | Double glazing + Low-E | Single glass, poor insulation |
| Mosquito/Insect Protection | Removable screen | No / non-removable screen |
| Usage Process | Silent roller + reinforced track | Roller easy to damage |
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.
UPVC windows offer superior thermal insulation with a lower U-value (≈ 1.30 vs 1.70), providing up to 65% energy savings. They are also corrosion and rust-free, making them optimal for humid and coastal climates.
Our UPVC profiles are structured with full-length steel/aluminum reinforcement inside the PVC frame, ensuring long-term structural stability, non-deformation, and smooth track operation.
We configure our windows with German-engineered multi-point locks and stainless steel silent rail rollers, delivering enhanced anti-theft security and whisper-quiet sliding motion.
Yes, the integrated insect screen is designed to be easily detachable for convenient maintenance and cleaning while ensuring constant airflow and reliable insect protection.
We utilize high-efficiency double glazing paired with Low-E coating, which effectively minimizes thermal transfer and maximizes indoor acoustic comfort.
Every window and door goes through an 8-step standardized process including precision cutting, corner brace assembly, glass cleaning, assembly, multi-layer sealing, rigorous performance testing, and safe export packing.
