To adapt to local conditions. The application of different doors and windows should be comprehensively considered according to factors such as the location of the building and the function of doors and windows. For example, in the north, use doors and windows with better thermal insulation performance; in the south, use doors and windows with better shading and waterproof performance.

Different regions have different requirements for door and window functions. The south generally needs heat insulation, the north generally needs heat preservation, and the south is windy and rainy, and the doors and windows need to have good waterproof performance.

To improve the energy saving of doors and windows, we must first improve the quality of the doors and windows themselves. It is necessary to improve the energy-saving design indicators of doors and windows, strengthen the thermal insulation and thermal insulation properties of door and window materials; improve the structure of doors and windows (double-layer, multi-layer glass, internal and external shading systems); improve their airtight performance from the structural design, production and installation of doors and windows.

The core of which is to improve the sealing performance of doors and windows. To improve the sealing performance, it depends on the sealing strip. The window sash and the window frame press the sealing strip to achieve the sealing effect, and this pressure is realized by hardware. The combination of lock point and lock block can improve the sealing performance of doors and windows. The more locking points of doors and windows, the better the sealing performance. Of course, the premise is that other materials of doors and windows are of high quality. Under the same quality, multi-point locks are better than single-point locks.

The door and window design should not only consider the material, but also the deformation of the profile and the elasticity of the sealing strip. The door and window with a single-point lock will only have the lock point. The sealing performance will be improved, while the other sides cannot achieve better sealing performance. Good sealing effect. Therefore, a good material may not achieve a good sealing effect, and must be used with high-quality door and window hardware.

German hardware is currently recognized as the better quality door and window hardware worldwide. Many doors and windows series products all use German hardware, so that owners can rest assured and comfortable in the purchase of doors and windows.
