Trend development of building doors and windows with energy saving and environmental protection
With the development of China's housing construction to industrialization, people have put forward higher requirements for the quality of residential function. In particular, the voice of the renovation of the traditional doors and windows is the highest, and the functional quality of the doors and windows has been paid more and more attention. At present, the material of door and window in our country has developed from simple wood and steel to composite material, and it develops from single function to multi function. Some people in the industry put forward constructive suggestions for the future development of residential doors and windows in China through the investigation of the doors and windows industry abroad and the analysis of the status quo of China's doors and windows industry. Experts in the industry believe that the nature and function of the window will be mainly to the energy saving development of airtight, thermal insulation and heat insulation. This requires that the window product should have a considerable strength, not warp. In the gap treatment of the window sash, the North window in the North should have double glass facilities. China is a country with a lack of energy, and the energy consumption is equal to two times that of the developed countries. According to the requirements of energy saving planning in China, the energy saving will reach 50% during the "fifteen" period. It can be predicted that the energy saving doors and windows will be paid more attention.
In the opening direction of the window is mainly to develop push and pull doors and windows, the development of new type of suspension and upper hanging window, in the room with energy saving and air conditioning requirements for the room. The development of window type tends to be miniaturized and active, in order to meet the requirements of modern small bedroom. Push and pull window, easy to open, flexible, no space, is conducive to the treatment of window sill, such as setting floughs and so on. In the development of the window, the experts suggest that the balcony window be pushed to the ground. The new type of well-off residential design emphasizes the role of the hall and expands the depth of the balcony. Use the floor window, not only indoor brightness and sunshine, but also to strengthen the indoor and outdoor contact, expand the field of vision, so that the indoor and external connection into a piece. The south area needs the floor door and window more, favorable ventilation. The roof window is another kind of new product to be developed. The slope roof structure is a good form of heat preservation, heat proof and leakage prevention, and it is a good form of rational use of space and increasing the living area. At present, there are almost no windows, such as lighting windows, ventilation windows, etc., which are suitable for sloping roofs in China.
The kitchen window to window strip development, located between the kitchen hanging cabinet and console. The toilet mainly develops the ventilation window, which has two functions of preventing sight and ventilation. For the development of residential doors, experts suggest that the development of housing push and pull and folding doors should be emphasized. These two products, especially for the small area of kitchen, toilet use, can play a role in the development of small space. This part of the key lies in the hardware, connection technology, light, low noise, tight, easy to clean, such products in foreign housing in a large number of use. With the improvement of the residential level in our country, the prospect of its development is very broad. Secondly, the safety door should be developed, which requires anti-theft, fire protection, sound insulation and insulation. It is suggested that the development of the outside of the size fan type with anti-theft, heat insulation, sound insulation three in one door. This is beneficial to save room space, open doors, strip shoes and change space. The setting of the small door fan provides convenient conditions for the daily entry and departure and the handling of large objects. The key technology lies in the anti-theft measures of the hinge, the fixing of the small fan and the sealing technology of the door seam.
At present, the unit gate has developed the intelligent form, which has the function of burglarproof, safety, intercom and automatic opening and closing. It has been applied in the south area. This technology is of high level, but has a reliable security function, convenient unit households, high-grade residential apartments will be welcome.
According to the above analysis, the experts in the industry suggest that the house doors and windows should be developed from the following aspects: high quality and high quality development. In particular, it should be emphasized that the doors and windows have the requirements of heat preservation and energy saving, and have the beauty and strength. The light plastic doors and windows should be developed to increase the variety.
We should vigorously develop new doors and windows, hardware products, and improve the function and quality of hardware.
