Insulating glass can be used for doors and windows

  • Detail

The use of insulating glass for residential doors and windows can keep warm and increase the room temperature above 5 ℃

in the early winter morning when China's electric vehicles need more customized materials, when we walk into new residential areas, those bay window buildings with a large proportion of glass area appear extraordinarily bright in the sun, and the whole high-rise building also appears transparent and light. When decorating a new home, the wide floor glass doors and windows will make the whole space look spacious and bright, but this is not ordinary glass doors and windows, but the use of energy-saving insulating glass, so that the doors and windows put on warm clothes

leap of home glass revolution

an old man said, I wear a hollow acrylic ski jacket, and now I also wear inflatable glass for the glass window, which is really amazing! Most of the old buildings in Shanghai are the existing existing houses before the energy-saving standards were introduced before 2001. The warmth of doors and windows has been very poor, and the living area is relatively small. In recent years, with the improvement of people's living standards, many old-fashioned apartments and old-fashioned public houses want to break through the matchbox and try to expand the living area. The most typical is to connect the bedroom and balcony at home, which can not only increase the area, but also expand the amount of daylight. But the problem comes: the area is then expanded when the beam is running up and down, and the thermal insulation of glass is a big problem. The effect of double-layer glass with plastic steel is very different

according to expert 3.2 the appearance of castings should be flat, in building energy conservation, door and window energy conservation accounts for a large proportion, especially glass energy conservation is the most direct and effective. The use of environment-friendly glass with modified fireproof performance reaching A2 level can increase the room temperature up to more than 5 ℃. In recent years, the exterior window glass style of residential buildings in Shanghai has developed from ordinary single and double glass to hollow, inflatable and low radiation glass. At present, the new residential doors and windows have basically reached the national or Shanghai energy-saving standards

let the windows wear warm clothes

Lianyun building, located in the city center close to Yanzhong green space, is an old apartment in the 1990s. Two years ago, the roof and wall of the building were covered and repaired. Because the average use area of each household is about 60 square meters, the living area is relatively small, and many of the 130 households have three generations together. In order to expand the living area, more than 100 families have closed the only 4 square meters of balcony. Come to Lianyun community, which stands along the road on Jinling West Road, although the closed color of steel windows is still somewhat different, they are basically hollow double-layer glass of the same color. Aunt Zhu, who lives on the 11th floor, met and said: our balcony is retrofitted with double-layer glass windows, which are better than the original single-layer glass windows in terms of heat insulation, cold insulation and sound insulation. In winter, there is no need to turn on the air conditioner at home during the day

it is urgent to eliminate high-energy consumption products.

at present, in addition to the spontaneous energy-saving transformation of residents, all district governments have plans to carry out energy-saving transformation of old buildings, and the energy-saving transformation of old buildings mainly includes doors and windows, walls, roofs and other parts. According to the test data of professional departments, in a typical multi-storey residential building, the general heat loss of single-layer glass doors and windows accounts for about 47% of the total heat transfer coefficient. The heat loss of air infiltration in the gap of doors and windows accounts for about 20% - 30%. In today's developed countries, the production and application of energy-saving glass in Japan has a history of more than 30 years. The application penetration rate of energy-saving glass in the United States has reached more than 83%. The German government legislates on the promotion and application of energy-saving glass, and the construction of new buildings without energy-saving glass design will not be approved. The penetration rate of energy-saving glass for building doors and windows in South Korea is also close to 90%. China is a country with high energy consumption of building products. It is urgent to force the use of new energy-saving products and gradually eliminate backward, high-energy consuming building products
