After 100,000 opening tests, the hardware maintains stability and function. The load-bearing capacity of all hardware can reach up to 150kg. The configuration of 3-9 locking points ensures safety, sealing performance, and stability.
Glass plays a vital role in windows. You can choose between 2 and 3 layers of glass to maximize insulation performance. Tempered glass is superior to ordinary glass in terms of thickness, toughness, and safety.


Thermal break windows and doors are made of high-quality hardware and insulating materials, featuring a hidden isobaric drainage system to prevent wind pressure, rain, and backflow. PA66 insulation strips provide the best insulation available.
