The key to energy-saving of doors and windows is to have high thermal insulation and thermal insulation performance on the premise of meeting their use functions. The most important thing of energy-saving of doors and windows is to solve the problem of heat cut-off of door and window profiles and the selection of glass with small thermal resistance value, so that doors and windows have high strength, high air tightness, high water tightness, high precision, excellent heat insulation and sound insulation performance. So, how to improve the energy-saving effect of doors and windows?
There is a problem of opening doors and windows, so the sealing treatment of the gap is a weak link, because the sealing is not good, the heat loss caused by convection is produced. Therefore, it is necessary to solve the problem of sealing performance after taking effective measures to reduce K value for both frame and glass.
1、 Improve sealing
1. Sealing top
The main factor that affects the sealing performance of the door and window sash is the sealing force between the door and window sash, and the main factor affecting the sealing performance of the door and window sash.
2. Hardware accessories
Doors and windows rely on hardware accessories to complete the function of opening and closing. They are the most easily worn and continuous part of building doors and windows. The effectiveness of their functions not only directly leads to safety problems, but also affects the thermal insulation performance, water tightness and air tightness of building doors and windows. Without high-performance hardware accessories as a guarantee, it is impossible to produce high-performance energy-saving doors and windows.
2. Optimize the section structure of door and window frame profiles
If there is no corresponding structural coordination after the emergence of new materials, its role will be limited. Different structures of the same materials have great difference in performance. For example, multi cavity heat insulation strip is used for frame, multi-channel seal is used for sealing, and matching with glass and accessories, K value is greatly reduced.
Glass with small thermal resistance
The movable sunshade is a good barrier to block the solar radiation. The movable sunshade shutter device is installed inside the open aluminum panel curtain wall, which can control the elevation and fall of the louver for reasonable sunshade in the room, and the louver can rise into the inner surface of the curtain wall when not in use.
Fourth, improve the level of manufacturing and installation
Installation is an important part of the window structure. The installation of the window plays a decisive role in whether the window can obtain good quality.
