why do we choose bridge broken aluminum alloy doors and windows instead of plastic steel doors and windows

compared with plastic steel windows, aluminum alloy windows have better durability, stability and firmness. In particular, the enclosed balcony and sunshine room are large-area, and the advantage of aluminum alloy in the overall anti deformation degree is unmatched by ordinary plastic steel (the curtain walls of our common office buildings and hotels are made of aluminum alloy). The advantage of plastic steel is that the heat transfer coefficient of its profile is relatively low, and the heat preservation performance is very good, so it is used more in the north. In recent years, the bridge breaking and thermal insulation technology of aluminum alloy doors and windows has been very mature, and the thermal insulation performance is also very good, so now the mainstream market is dominated by aluminum alloy. Plastic steel mainly occupied the relatively cheap low-end market

how to choose aluminum alloy doors and windows

it is recommended to cut off the thermal insulation aluminum alloy doors and windows, which have the characteristics of thermal insulation, sound insulation and noise reduction, and good tightness

what is broken bridge insulation

in the past, ordinary doors and windows, first of all, the glass is single-sided, and the aluminum alloy frame is also integrally formed. The metal and glass itself are easy to heat transfer, so the thermal insulation performance is very poor. The current bridge breaking insulation is to add a PA66 insulation strip (black plastic in the figure below) in the middle of two aluminum alloy profiles. Because the heat transfer coefficient of plastic is very poor, the heat transfer is broken, so it is called broken bridge. At present, 5mm+15a+5mm insulating glass is commonly used. 15A is the thickness of the air layer between the two pieces of glass, so the heat transfer of the glass is also isolated by the air layer, which is a bit like the principle of a thermos. Therefore, the thermal insulation performance of the broken bridge is very good

what kind of aluminum alloy profile is better

the thickness of aluminum profile of windows should generally reach 1.4mm, and the thickness of aluminum profile of doors should reach 2.0mm. Common mainstream brands are: Central Asia, phoenix aluminum, Xingfa, Dongliang, Nanshan, Chinalco, Weiye, etc. It's right to choose these kinds

what kind of glass is better

first, the original glass (conventional ground glass) is produced by large factories, and then the processing is deepened through the processing factory. There are concave shape, coating and tempering. Normally, the glass of our aluminum alloy glass doors and floor to ceiling windows needs to be tempered within one meter from the ground, because the landing doors and windows are vulnerable to impact. Even if they are damaged after tempering, sharp small glass (see the following figure) will not be produced, resulting in scratches. As long as the glass is ordinary glass, it should be tempered below 1 meter, and the air layer thickness of double-layer glass is best 15 mm

what are accessories

accessories mainly refer to the hinges of aluminum alloy windows, handles, tracks of aluminum alloy doors, handles, etc. (see the figure below). Simple examples, such as our ordinary door hinge, handle lock, etc

is it OK to choose the right accessories, profiles and glass

no, because the right material depends on the processing level. The doors and windows of our general commercial houses are aluminum alloy doors and windows processed by large door and window manufacturers as a whole. But if we seal the balcony and find a roadside workshop to make it. There are great differences in processing equipment, management ability and processing accuracy. So the materials are the same, but the results are different. If you want to ensure the quality, find a large door and window manufacturer such as Shangzhe system door and window to do it. In this way, the quality will be relatively guaranteed

all the above are selected, is it OK

the last step is field installation. Aluminum alloy doors and windows are installed again after the house is built, so there are many different materials on site to connect with aluminum alloy, such as stone, face brick, paint, cement, etc. There will also be many irregular faces. So why our own balcony is always leaking

there are several precautions to control well

1, be sure to measure accurately, so that the gap between doors and windows and buildings will not be very large, and it is normally controlled at a gap of 2~3 cm

2, the gap between doors and windows shall be filled with foaming agent after fixing, and the foaming agent shall be filled densely and evenly

3, after filling the foaming agent, you need to apply glue finally. The interface with face bricks and stones is directly glued, and the interface with cement is plastered with cement mortar before gluing. After gluing, check whether there is missing glue and uneven glue surface
