How to Buy High-Quality Aluminum Alloy Doors and Windows?
Aluminum alloy doors and windows are popular due to their excellent sound and heat insulation, lightweight, high plasticity, and fire resistance. They are often the first choice for doors and windows during home renovations. So, how can you buy high-quality aluminum alloy doors and windows?
Generally, high-quality aluminum alloy doors and windows have a bluish-white surface. If the surface is snow-white and glaring, it indicates poor sun protection. This material contains too much calcium, which can easily age, deform, and crack over time. If the profile has bubbles, dents, or cracks, it is a low-quality profile. For example, pits or wavy edges indicate a short lifespan and aesthetic issues; such profiles are not recommended.
High-quality aluminum alloy doors and windows use metal hardware that is strong, has a smooth appearance, and is durable. When purchasing aluminum alloy doors and windows, carefully check whether the welded corners are firm, neat, and aesthetically pleasing, whether the hardware is complete, and whether there is steel reinforcement, etc.
03 Check the Sealing Performance
The sealing performance of aluminum alloy doors and windows is particularly important. Poor-quality doors and windows have poor sealing performance, allowing rainwater to seep into the room and cause mold on the interior walls.
HENGYIN's thermally broken aluminum doors and windows use materials with a special formula. The material itself has a water absorption rate of less than 0.1%. Double-layer sealing is used between the frame and sash, and high-quality sealing strips are installed in all gaps. Drainage holes are opened at appropriate locations in the door and window frame. The corners are also mechanically welded, resulting in excellent sealing performance, preventing water leakage, and providing moisture, sound insulation, and heat insulation, naturally leading to a longer service life.
04 Check Brand Qualifications
Qualified merchants provide more reliable service. When purchasing aluminum alloy doors and windows, do not be tempted by low prices and choose unqualified merchants. If quality problems arise with the doors and windows, you will only have yourself to blame.
