How to improve the thermal insulation of broken bridge aluminum doors and windows?
No matter in the ice and snow, or the hot summer, doors and windows are one of important building envelope structures. They can play the functions of wind and rain protection, heat and sound insulation, lighting and ventilation, etc., and they also have a great impact on people's working and living environment. important role. It is believed here that if you want to improve the thermal insulation performance of broken bridge aluminum doors and windows, you must solve technical problems.
1. The thermal insulation performance and air permeability performance of broken bridge aluminum doors and windows meet the current energy-saving building design standards. It is a building energy-saving product that is currently strongly advocated and promoted in our country. Broken bridge aluminum doors and windows are separated by materials with low thermal conductivity (insulation strips) in the middle of the aluminum profile to artificially block the heat transfer path of the aluminum profile. At the same time, technical measures such as insulating glass are installed to greatly improve the thermal insulation of broken bridge aluminum doors and windows. Thermal insulation and energy saving effect.
2. Promote the use of double-channel sealing and insulating glass made of polysulfide hollow proportional glue. Insulating glass spacers should adopt a continuous angle structure. If a four-corner plug-in type is used, butyl rubber must be used for sealing the joints. deal with. Single-pass sealed insulating glass is not available, and it is not advisable to use silicone structural adhesive for secondary sealing of insulating glass because their service life is relatively short.
3. Insulating glass should be used according to the different needs of the North and the South, and the use of Low-E type (low-radiation) insulating glass should be promoted in the North. In the south, where solar radiation heat dominates, the use of solar-coated glass should be promoted. In foreign developed countries, single glass and white glass are no longer used because they are not conducive to energy saving and improving the living environment.
4. Some so-called double-glass ones are not available either. To reduce the heat transfer coefficient and keep the price low, some window types use double glass. That is, the two layers of glass are separated or glued to the window with ordinary sealant. No molecular sieve is used to absorb moisture, and it is only a single-pass seal. Even if the insulating glass is made of polysulfide insulating glass glue, if only a single seal is used, the sealing life will be very short, which is not allowed to be used in the glass curtain wall regulations. What's more, if it is sealed with ordinary sealant, its service life will be very short. Shorter.
5. It is also worth noting that during building construction, it is not advisable to use 5mm thick glass for broken bridge aluminum windows and doors. Because 5mm thick glass is used in windows with larger partition areas, safety is also a worrying issue. If it is to be used, it should be used after strength calculation and on the premise of ensuring safety. It must not be used indiscriminately. Accessories must be durable, easy to use, and beautiful.
