Characteristics of high grade thermal insulation broken bridge aluminum doors and windows
09:00-09:00

Thermal insulation (heat insulation broken bridge) aluminum alloy door and window is a new product introduced into China from abroad in recent years. It is made of heat insulation aluminum alloy profiles. The thermal insulation aluminum alloy profiles are divided into two categories: one is the strip type, the other is the glue injection type. At present, more than 80% of the thermal insulation aluminum doors and windows in the market are made of through bar heat insulation aluminum alloy profiles. Therefore, this kind of thermal insulation aluminum alloy doors and windows is the leading product in the market.

The principle of bridge broken aluminum doors and windows is to use plastic profiles (heat insulation is 1250 times higher than aluminum profiles) to separate and connect two layers of aluminum alloy Indoor and outdoor into a whole, forming a new type of thermal insulation aluminum profiles. Using this profile as doors and windows, its thermal insulation is in the same level as plastic (steel) windows - national standard level, which completely solves the problem of fast conduction and heat dissipation of aluminum alloy At the same time, some new structure matching forms are adopted to solve the old and difficult problem of "the aluminum alloy sliding window is not tightly sealed". The two sides of the product are aluminum, and the middle is made of plastic profile cavity. This innovative structural design takes into account the advantages of plastic and aluminum alloy, and meets the requirements of decoration effect, strength and aging resistance of doors and windows. The super bridge broken aluminum-plastic profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully realize the gas water isobaric balance, and significantly improve the water tightness and air tightness of doors and windows. The air tightness of this kind of window is better than that of any aluminum or plastic window. It can ensure that there is no dust on the windowsill and floor in the windy and sandy area, and the residents within 50 meters on both sides of the expressway are not disturbed by noise, and its performance is close to that of the casement window.

This kind of window combines the advantages of aluminum and plastic windows, and eliminates their respective shortcomings, thus becoming an ideal choice for users. At present, the price of this kind of window is about 360-400 yuan / m2. Although it is slightly higher than the ordinary aluminum and plastic sliding window in the market, the comprehensive use effect of this window is much better than that of ordinary aluminum and plastic composite window, and even better than double-layer aluminum sliding window. In this sense, it is worthwhile to spend 30-50 yuan more 50% of the heating and air conditioning electricity costs can be saved, and the three-year energy-saving cost is enough to make up for the initial investment.

Through the bar type heat insulation aluminum alloy profile is to divide the traditional integrated aluminum profile into two parts, and then use two low thermal conductivity heat insulation strips to connect the separate aluminum profiles by mechanical composite means, so as to solve the problem of heat conduction energy consumption of aluminum door and window profiles. This kind of thermal insulation aluminum doors and windows has been used for more than 30 years in Europe. In particular, it has accumulated mature experience in the material selection, structure, stress, connection, sealing and other quality control of aluminum doors and windows special insulation strips, and has formulated a set of technical standards. Referring to the relevant European standards, China has formulated and promulgated the national technical standards for thermal insulation aluminum profiles. However, there are still many unsatisfactory aspects in the production and use of thermal insulation aluminum doors and windows in China. Among all kinds of information fed back by the market, the quality problem of poor quality aluminum doors and windows products, especially the profile heat insulation strip, is the most prominent. This not only causes market confusion and often causes disputes, but also makes the engineering quality not guaranteed and damages the interests of consumers.
