With the great improvement of social living standard and the rising of technological level, aluminum alloy windows are no longer products without styles. A variety of aluminum alloy windows appear in the market, which are widely used in home decoration due to their strong decorative characteristics. If consumers want to choose high-quality aluminum alloy windows, they need to have a certain understanding of them.

Learn the classification and advantages of aluminum alloy windows before purchasing

Aluminum alloy window is the first product to replace steel windows. It is made of aluminum alloy extruded profiles for frames, stiles and fans. Ordinary aluminum alloy sliding windows are mainly made of aluminum alloy, with better sealing and sound insulation than steel windows, and easier to process than pure wood windows and steel windows.

1. Classification of aluminum alloy windows

Classification by opening mode: aluminum alloy windows can be divided into aluminum alloy casement windows (internal opening, external opening), aluminum alloy sliding windows, aluminum alloy suspension windows (upper suspension, middle suspension, lower suspension) and aluminum alloy fixed windows as well as other materials. Different ways of opening and closing aluminum alloy windows have their own advantages and disadvantages. They are suitable for different spaces. Consumers can choose them according to the actual situation.

According to profile classification: aluminum alloy window can be divided into ordinary aluminum alloy window and broken bridge aluminum alloy window. The broken bridge aluminum alloy window is an improved window based on the ordinary aluminum alloy window in order to improve the thermal insulation performance of the window. Aluminum alloy profiles are divided into inner and outer parts by reinforced nylon strips to block the heat conduction of aluminum. The bridge cutoff aluminum alloy window has superior thermal insulation, which completely solves the problems of fast conduction and heat dissipation and poor thermal insulation of ordinary aluminum alloy window.

2. Advantages of aluminum alloy windows

Compared with other material windows, the biggest disadvantage of aluminum alloy is the fast conduction and heat dissipation. But aluminum alloy windows also have many advantages worth choosing.

Aluminum alloy window is made of aluminum with light weight, high strength and density only 1 / 3 of steel.

Aluminum alloy windows have good airtight performance. Airtight performance directly affects the use function and energy consumption of windows. Airtight performance includes airtightness, water tightness, heat insulation and sound insulation. Aluminum alloy windows have good air tightness, water tightness and sound insulation.

Aluminum alloy window has good durability and is easy to use and maintain. Aluminum alloy windows are not rusted, discolored, peeled off, almost maintenance free, and the service life of spare parts is very long.

The decorative effect of aluminum alloy window is good. The surface of aluminum alloy window has artificial oxide film and colored to form a composite film. It is not only corrosion-resistant, wear-resistant, but also has a certain fire resistance. Moreover, it has high glossiness and elegant appearance.

How to choose aluminum alloy window

When consumers choose aluminum alloy windows, how to judge the quality of products. In order to facilitate the selection of products with good quality and appropriate price, please refer to some methods listed below.

Look at the material.

The main materials used for aluminum alloy windows generally include three aspects: aluminum profile, glass and hardware. The wall thickness of aluminum profile used for high-quality aluminum alloy windows shall be no less than 1.2mm, and the thickness of oxide film shall be 10 microns; toughened glass is better than ordinary glass; hardware accessories made of stainless steel (such as screws, hinges, handles, etc.) are better than aluminum accessories.

Two look at processing

High quality aluminum alloy window, with fine processing, smooth tangent and consistent angle (the main frame material is usually 45 or 90 degrees), should not have obvious gap in the splicing process, with good sealing performance and smooth switch. If the processing of poor quality aluminum alloy windows, especially the outdoor aluminum alloy windows is not qualified, there will be sealing property problems, not only air leakage and rain leakage, but also under the action of strong wind and large external force, the glass will crack and fall off.

Three look at the appearance.

There shall be no obvious scratch, scratch, bump and other defects on the window surface. There shall be no obvious color difference on the colored surface of adjacent components on the window. The window surface shall be free of aluminum chips, burrs, oil spots or other stains, and the assembly joints shall be free of overflowing adhesive.

Four look at performance

The performance of aluminum alloy windows usually needs to consider the following aspects: strength, which is reflected in the selection of profiles of aluminum alloy windows, whether they can withstand ultra-high pressure; air tightness, which is mainly reflected in the window structure, whether the inner leaf and outer frame structure of windows are tight, etc.; water tightness, which is mainly to check whether there is water accumulation and leakage in aluminum alloy windows; sound insulation, which is mainly determined by the sound insulation effect of hollow glass And other special sound insulation airtight strip structure as well as the durability of opening and closing force, opening and locking durability and other window accessories.

Five look at the price.

In general, the price of high-quality aluminum alloy windows is 30% higher than that of low-quality aluminum alloy windows. The low-quality aluminum alloy windows usually use recycled aluminum extruded profiles with a lot of impurities. Some of the aluminum profiles used are only 0.6-0.8mm thick, which are much lower than the relevant national regulations in terms of tensile strength and yield. Such aluminum alloy windows, especially the aluminum alloy outdoor windows, are very unsafe , so don't look down upon personal safety of yourself and others with a view to temporary cheapness.
