recently, most places in the South continue to be hot, but the northern region continues to suffer from snowstorms, and the temperature continues to drop. Many places began to supply heating very early. It's cold outside the window, but it's warm inside. Poor window insulation will affect the temperature in the house. Improving its heat insulation and energy-saving functions is the key technical problem to be dealt with in the future for aluminum alloy doors and windows. To improve the structural mode and complete the diversified system planning, we should improve the functions and levels of existing doors and windows, change the low-level structure that used to only seek labor-saving, material-saving and low price, and complete the transition from sliding windows to casement windows with better functions

window sound insulation

1. The general requirements of frame materials should be good strength, good heat insulation function, easy to make into various shapes, easy to recover and conducive to environmental protection. In order to improve its heat insulation function, aluminum alloy window frames should be made of broken bridges or composite ones

2. Insulating glass should be promoted and used, and Low-E type (low radiation) insulating glass should be promoted and used in the north. In the south, the use of solar coated glass should be promoted in areas dominated by solar radiant heat. Foreign developed countries have basically no need for single glass and white glass, because they are not conducive to energy conservation and improving the living environment. 3. Promote the use of double sealing and insulating glass made of polysulfide insulating glass glue. The insulating glass distance strip should choose the continuous angle structure. If the four corner plug-in type is used, the joint must be sealed with butyl rubber. Single sealed insulating glass cannot be used, and the insulating glass with silicone structural adhesive as secondary seal cannot be taken, because their service life is relatively short

4. Other so-called double glasses are also useless. In order to reduce the heat transfer coefficient and reduce the price, some window types choose double glass, that is, separate the two layers of glass or install it on the window with general sealing adhesive. There is no need for molecular sieve to absorb moisture, but only a single seal. Generally, the sealant is not resistant to aging. After a short time, it will be dusty and cannot be scrubbed, which will affect the vision and is extremely unsightly. Because the insulating glass made of polysulfide insulating glass adhesive, if only a single seal is used, the sealing life is only five years, which is expressly prohibited in the glass curtain wall standard. Moreover, if it is sealed with general sealant, its life is shorter. One of the most crucial aspects of the construction project is the service life, that is, durability. Using this kind of double glass is only a temporary expedient, which is very useless

5. Moreover, 5mm thick glass cannot be used on the doors and windows of high-rise buildings. As 5mm thick glass is used on windows with large partition area, safety is also a concern. If you want to use it, you should also use it on the premise of ensuring safety after strength accounting. Don't use it indiscriminately. All kinds of accessories must be durable, easy to use and beautiful. Accessories have an important impact on the functions of doors and windows, and together they play an important decoration effect, so they cannot be ignored
