First, choose the right window frame. Considering the large window area in most houses (such as enclosed balconies) and the prevalence of high-rise buildings, the frame thickness should be greater than 2.5 mm, with a three-cavity structure including a closed drainage cavity, an isolation cavity, and a reinforcement cavity. This ensures the window won't deform for decades. Additionally, such frames are less prone to discoloration and aging.
Second, observe the surface smoothness of the PVC windows and doors, checking for obvious scratches, cracks at the welds, and whether the corners are neatly and evenly finished.
Third, choose high-performance hardware that opens and closes smoothly.
High-quality PVC windows and doors should be combined with advanced window design for lifelong benefits. For example, for residences with high levels of outdoor noise, PVC windows with double-glazed windows are ideal, offering excellent sealing and sound insulation. Furthermore, from a design perspective, different window types can be designed to meet various needs. For instance, higher-end windows are inward-opening top-hung windows, suitable for master bedrooms; outward-opening casement windows are suitable for studies and living rooms; and sliding windows are suitable for enclosed balconies. For windows with larger openings, combination windows or similar designs can be used.
Windows are an integral part of a building and should have the same lifespan as the building itself. Choosing good doors and windows is a significant guarantee of the quality of your home.
