Thermal Break aluminum profile
Thermal Break insulation Window and Door Aluminum Profile
Heavy-duty sliding door aluminum profile purchase notes:
1, the purchase of heavy-duty sliding doors should pay attention to the thickness of the profile, the national standard aluminum alloy profile wall thickness cannot be less than 1.2 mm. The high quality heavy sliding doors reach 1.8mm-2.5mm.
2, pulleys, good pulleys with strong gravity, push and pull times up to 100,000 times, smooth sliding, no noise. Recommended glass pulley or imported stainless steel pulley, strong wear resistance, smooth sliding feel, durable. And pay attention to the design of the upper pulley block, check whether the pulley of the same material is used, and whether there is a bearing.
Pay special attention to these two points when purchasing.
The aluminum door and window of the broken bridge are similar in appearance to the aluminum alloy, and this is also a door and window made of aluminum alloy material. In fact, it is an upgraded and improved version of the aluminum alloy door and window. The biggest difference lies in its "broken bridge". The craft is gone.
The most important part of this "broken bridge" process is the insulation strip in the broken bridge aluminum. There are two kinds of materials currently used for the insulation strip. One is PA66 nylon insulation strip (European, strip-squeezed, cavity), and the other is polyurethane injection (American, cast, most without cavity) .
It is made of a material with poor thermal conductivity in the middle part of the aluminum alloy profile for thermal conduction blocking, thereby achieving the effects of heat insulation and heat preservation. The so-called "bridge" refers to the cold and hot bridge in architecture. The cold and heat will spread rapidly through the metal, and the function of the broken bridge is to use different materials to break the cold and heat and block the circulation of heat insulation.
Simply put, the traditional aluminum alloy doors and windows due to metal heat conduction is relatively fast, the indoor and outdoor temperature difference is large, aluminum alloy has become the "bridge" of heat transfer. The broken bridge is to disconnect the aluminum alloy from the middle, and the separator with low thermal conductivity is connected with the aluminum alloy on both sides, so that the heat is not easily transmitted, so it is called bridge aluminum.
With the heat insulation strip, the aluminum door and window of the broken bridge can play the role of heat insulation, fire prevention, heat preservation, etc., and the glass tempered insulating glass is used, which has remarkable effect on the sound insulation and noise reduction effect, and the air sound insulation reaches the sound insulation 30- -40db, even if you live on the side of the road, you can have a quiet and comfortable living place.
Of course, a good door and window, not only look at profiles, hardware and glass. The most important thing is to look at the overall process. Only the strict production process and the standard installation process can truly realize the value of the broken aluminum doors and windows.
The characteristics of aluminum alloy doors and windows compared with steel doors and windows, aluminum alloy doors and windows have the following advantages:
l) Light weight and high strength. The density is only l/3 of the steel.
2) Good sealing performance. The sealing performance directly affects the use of windows and doors and energy consumption. The sealing performance includes four aspects: airtightness, watertightness, heat insulation and sound insulation.
3) Good durability and easy maintenance. Aluminum alloy doors and windows are not rusted, fading, non-shedding, almost no maintenance, and spare parts have a very long service life.
4) The decorative effect is elegant. The surface of the aluminum alloy door and window has an artificial oxide film and is colored to form a composite film layer. The composite film not only has corrosion resistance, wear resistance, but also has certain fireproofing power, and the gloss is extremely high. Due to its light weight and precise and accurate machining, the aluminum alloy doors and windows are light and flexible, and no noise.
What is a broken bridge: the broken bridge in the door and window is only available in aluminum alloy doors and windows. The aluminum door and window of the broken bridge is also called the heat-insulating aluminum alloy door and window, and the doors and windows made of broken aluminum and insulating glass. There are two kinds of production methods: one uses heat insulation strip material and aluminum profile, and forms a heat insulation bridge through mechanical toothing, rolling, wearing strips, etc., and another heat insulation material is poured into the aluminum alloy profile. In the body, after cooling and solidification, removing the bridge and other processes to form a heat insulation bridge, it is called a cast type heat insulation profile.
The two sides of the heat-insulating profile can be different profile or different colors on different surfaces. However, due to the influence of geography and climate, in order to avoid the excessive gap between the coefficient of linear expansion of the heat insulating material and the aluminum profile, the heat expansion and contraction is a large stress and gap between the two, and the heat insulating material and aluminum are required. The profiles are integrated into one, and in the structure of doors, windows and curtain walls, they are also subjected to the same force as aluminum. Therefore, the insulation material must also have tensile strength and bending strength similar to those of the aluminum alloy profile, otherwise the insulation bridge will be damaged. Therefore, the choice of insulation is very important.
The importance of broken bridge doors and windows for environmental protection: energy conservation, recycling, no harmful substances in the production process, in line with the concept of sustainable development, rich colors and exquisite style, can meet the needs of people in many aspects, create a pleasant space.
