Choose the right window type
Sliding windows are common for balconies and compact rooms. Casement windows often seal better and can be useful for bedrooms or study rooms where noise and dust control matter. Fixed windows suit areas where daylight and view are needed without opening movement.
Profile and reinforcement matter
A good uPVC window should have a stable profile, proper steel reinforcement where required, clean welding, neat corners, and compatible gaskets. Weak reinforcement can lead to shutter movement, poor locking, and long-term alignment issues.
Glass, mesh, and hardware
- Glass: select toughened, laminated, tinted, or insulated glass based on safety, heat, and noise needs.
- Mosquito mesh: check that mesh shutters slide smoothly and can be removed for cleaning.
- Locks: choose firm handles, multi-point locks where useful, and hardware that has service support.
- Drainage: confirm weep holes and sill slope before accepting installation.
Installation decides performance
Even a good uPVC system can leak or jam if measurement, fixing, leveling, sealing, and drainage are poor. Ask the vendor how they measure openings, fill gaps, seal frames, and handle service complaints after handover.
