What does the broken bridge of the aluminum profile refer to, and what is the broken bridge aluminum

Broken bridge aluminum is heat-insulated broken bridge aluminum. Thermal insulation bridge aluminum is a non-metallic low thermal conductivity separator sandwiched in the middle of the aluminum profile, which can obtain excellent thermal insulation performance of the aluminum profile, this is because the heat conduction is blocked when the heat is conducted to the non-metallic isolator through the aluminum alloy with excellent thermal conductivity, and the heat can not be transferred to the inner wall, such aluminum is called broken bridge aluminum. A broken bridge means that heat energy can be transferred indoors and outdoors.

Its principle is: the use of plastic profiles (thermal insulation is 1250 times higher than the aluminum profile) to separate the indoor and outdoor two layers of aluminum alloy and closely connect them into a whole, constituting a new thermal insulation type of aluminum profile, with this profile as a door and window, its thermal insulation and plastic (steel) windows in the same level of national standard. It completely solves the fatal shortcomings of aluminum alloy conduction and heat dissipation, which does not meet the requirements of energy saving; At the same time, some new structural cooperation forms were adopted, which was completely solved"The aluminum alloy sliding window is not tightly sealed"the old and difficult problem; The airtightness of this kind of window is better than that of any aluminum and plastic window, which can ensure that the indoor window sill and floor in the area with large wind and sand are free of dust; It can ensure that residents within 50 meters on both sides of the highway are not disturbed by noise.

Its performance is close to that of casement windows. The broken bridge aluminum-plastic composite doors and windows are made of heat-insulating aluminum profiles and insulating glass, imitating European-style structure, with beautiful appearance, and have the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproof.

Hello, broken bridge refers to a kind of thermal insulation profile made of non-metallic material. Aluminum alloy belongs to metal, so the thermal conductivity of aluminum alloy doors and windows is strong, and the indoor temperature is greatly affected by the outdoor temperature.

Broken bridge aluminum windows are windows made of broken bridge aluminum. Broken bridge aluminum is to disconnect the aluminum alloy from the middle, and then use hard plastic to connect the broken aluminum alloy as a whole, we know that the heat conduction of plastic is obviously slower than that of metal, so that the heat is not easy to pass through the whole material, and the thermal insulation performance of the material becomes better, which is the origin of the name "broken bridge aluminum (alloy)". Because aluminum alloy is a metal, the heat conduction is relatively fast, so when the indoor and outdoor temperature difference is a lot, aluminum alloy can become a "bridge" to transfer heat.

Broken bridge aluminum doors and windows do not have this shortcoming.

Answer: Broken bridge refers to the heat insulation strip in the broken bridge aluminum material, there are two main types of heat insulation strips on the market, one is polyurethane glue, it is a pouring type, most of them are cavity-free structure. The other is PA66 nylon heat insulation strip, which is a kind of strip extrusion type, for the cavity structure, at present in the Chinese market, the main popularity is the latter.

There are more and more broken bridge aluminum doors and windows products on the market, but what kind of products are called broken bridge aluminum? Let's uncover the horn together.

Broken bridge aluminum: Thermally insulated broken bridge aluminum profile.

There is little difference between broken bridge aluminum doors and windows and aluminum alloy doors and windows, they are all aluminum alloy materials, broken bridge aluminum is an improved version of ordinary aluminum alloy, the biggest difference is the process used in broken bridge aluminum - broken bridge. At present, there are two main kinds of thermal insulation strips in China's market, one is polyurethane glue, which is a kind of pouring type, most of which are cavity-free structures. The other is PA66 nylon heat insulation strip, which is a kind of strip extrusion type, which is a cavity structure, and is mainly popularized in the Chinese market.

Broken bridge aluminum is also called heat insulation broken bridge aluminum profile, heat insulation aluminum alloy profile, broken bridge aluminum alloy, cold and hot bridge profile, broken bridge aluminum-plastic composite profile. It has better performance than ordinary aluminum alloy profiles.

Broken bridge aluminum structure.

The so-called broken bridge aluminum is to use heat insulation strips to build a small bridge in the middle of the aluminum profile. The most widely available insulation strip materials are PVC, nylon strip and nylon strip with 25% glass fiber. It doesn't take up much of the entire window, but it's a very important section.

Isolation heat conduction is by it, in addition to the heat insulation strip of the broken bridge, there is also a very important sealing strip, generally plastic steel windows are two, and there will be a high-pressure sealing strip in the middle of the broken bridge window. Prevent dust and rain from entering the room.

Functional coefficients. The broken bridge aluminum door and window system has the functions of energy saving, sound insulation, noise prevention, dust prevention, and waterproof. Its thermal conductivity k value is less than 3w·k, which is half of the heat loss compared with ordinary doors and windows, reduces heating costs by about 30%, and has a sound insulation of more than 29 decibels, with good water tightness and air tightness.

The bridge of broken bridge aluminum refers to the hot and cold bridge.

The heat transfer of metal is faster than that of brick cement. In winter, when you touch the walls of your home, you may just feel cold; But if you touch a metal window frame that hasn't been broken before, it feels like ice. The metal window frames act like a bridge, transporting heat out of the house in a constant stream.

Broken bridge aluminum is to add a layer of insulating hard plastic between the two layers of metal frame, breaking the bridge, so that the heat is not so easy to escape. The material of this layer of hard plastic is generally PA66, which is not visible.

Broken bridge aluminum model

The model number of Broken Bridge Aluminum represents the width of its outer frame, which is the place where the picture below is 60mm. At present, the product models of mainstream broken bridge aluminum manufacturers on the market mainly include 60, 65, 70, 80 and other models. The larger the model, the better the thermal and sound insulation effect of the broken bridge aluminum window.

Sales data from manufacturers show that in 2017, the sales volume of different models of products accounted for 50% of the 60 models, 40% of the 70 models, and 65 models and 80 models, one accounted for 8%, and the other accounted for 2%. It seems that the 60 and 70 models of broken bridge aluminum are the mainstream products in the market.

Generally speaking, the wall thickness of the 60 model broken bridge aluminum window is 5+18a+5 in the glass hollow layer. The wall thickness is the thickness of the aluminum plate, 5+18a+5, which means that the thickness of the glass is 5mm; The 18 in the middle indicates that the distance between the two pieces of glass is 18mm.

Correspondingly, the 70 model glass insulating layer 5+27a+5 represents the glass thickness of 5mm, and the wall thickness of the glass spacing model is different, the thicker the stronger, and the more expensive.

In addition to the model, good broken bridge aluminum doors and windows also need to be selected:

Window hardware

Good hardware is relatively heavy, the switch is smooth but not slack, tight but there is no sense of blockage.

Glass

Hollow laminated glass has become the best glass combination with sound insulation effect at present, and is suitable for airports, subways, ring roads and other noisy places.

1. What is the broken bridge aluminum window?

Broken bridge aluminum is also called heat insulation broken bridge aluminum profile, heat insulation aluminum alloy profile, broken bridge aluminum alloy, broken bridge bridge profile, broken bridge aluminum-plastic composite profile. It has better performance than ordinary aluminum alloy profiles.

The "bridge" in the name "broken bridge aluminum" refers to the "hot and cold bridge" in the material sense, and the word "broken" means action, that is, "to break the hot and cold bridge". Specifically, because aluminum alloy is a metal and conducts heat relatively quickly, when the indoor and outdoor temperatures are very different, aluminum alloy can become a "bridge" for heat transfer. We know that plastic heat conduction is obviously slower than that of metal, so that the heat is not easy to pass through the whole material, and the thermal insulation performance of the material becomes better, which is the origin of the name "broken bridge aluminum window (alloy)".

What are the advantages of broken bridge aluminum?

Reduced heat conduction:The thermal conductivity of the aluminum alloy profile with thermal insulation and bridge is much lower than that of ordinary aluminum alloy.

Prevent condensation:The temperature of the inner surface of the profile with thermal insulation effect is close to the room temperature, which reduces the possibility of indoor moisture condensing to the surface of the profile due to oversaturation.

Energy saving:In winter, insulating window frames can reduce the amount of heat lost through the window frame by one-third. In the summer, when air conditioning is available, window frames with thermal insulation can reduce energy loss.

Protecting the environment:The use of thermal insulation systems reduces energy losses and reduces environmental radiation caused by air conditioning and heating.

Good for your health:The exchange of heat between the human body and the environment depends on the temperature of the air in the room, the speed at which it flows, and the temperature of the outside air. The room temperature of the doors and windows is adjusted so that it is not less than 12 to 13 degrees Celsius to achieve a very comfortable environment.

Noise Reduction:The use of insulating glass structure with different specifications and the cavity structure of broken bridge aluminum profile can effectively reduce the resonance effect of sound waves, isolate the transmission of sound, and reduce the noise by more than 30 decibels.
