Aluminum alloy window is the first product to replace steel window. Aluminum alloy extruded profile is used as frame, stile and fan material. Ordinary aluminum alloy sliding window is mainly made of aluminum alloy, which has better sealing and sound insulation effect than steel window and is easier to process than pure wood window and steel window.
Classification by opening mode
Like other materials, aluminum alloy windows can be divided into aluminum alloy casement window (open inside and outside), aluminum alloy push-pull window, aluminum alloy suspended window (upper suspension, middle suspension, lower suspension) and aluminum alloy fixed window. Aluminum alloy windows with different opening and closing modes have their own advantages and disadvantages, which are suitable for different spaces. Consumers can choose according to the actual situation.
Classification by profile
The aluminum alloy window can be divided into two types: ordinary aluminum alloy window and Bridge broken aluminum alloy window. The broken bridge aluminum alloy window is an improved window which is based on the ordinary aluminum alloy window in order to improve the thermal insulation performance of the window. The aluminum alloy is divided into two parts to enhance the heat conduction. The thermal insulation of bridge broken aluminum alloy window is superior, which completely solves the problems of fast conduction and heat dissipation and poor thermal insulation of ordinary aluminum alloy window.
Advantages of aluminum alloy window
The aluminum alloy window is made of aluminum with light weight, high strength and density of about 1 / 3 of steel.
Aluminum alloy window has good airtight performance. The airtight performance directly affects the use function and energy consumption of windows. The airtight performance includes air tightness, water tightness, heat insulation and sound insulation. The air tightness, water tightness and sound insulation of aluminum alloy windows are good.
Aluminum alloy window has good durability and is easy to use and maintain. The aluminum alloy window is not rusty, colorless, falling off, almost no maintenance, and the service life of spare parts is long.
The decorative effect of aluminum alloy window is good. The surface of aluminum alloy window has artificial oxidation film and colored to form a composite film, which is not only corrosion-resistant, wear-resistant, but also has a certain degree of fire resistance, high gloss, elegant and beautiful.
Tips for choosing aluminum alloy window
1. Look at the material
The main materials used for aluminum alloy windows generally include three aspects: aluminum profiles, glass and hardware. The wall thickness of aluminum profiles used for high-quality aluminum alloy windows should be no less than 1.2mm, and the thickness of oxide film should be about 10 μ m; tempered glass is better than ordinary glass; stainless steel five metal accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories.
2. Look at processing
High quality aluminum alloy window, fine processing, smooth tangent, consistent angle, in the splicing process should not appear more obvious gap, good sealing performance, smooth switch. Poor quality aluminum alloy window, especially aluminum alloy outdoor window products, if the processing is not qualified, there will be sealing property problems, not only air and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off.
3. Look at the appearance
There should be no obvious scratch, scratch, bruise and other defects on the window surface. There should be no obvious color difference on the colored surface of adjacent components on the window. There should be no aluminum chips, burrs, oil spots or other stains on the window surface, and there should be no adhesive overflow at the assembly joint.
The performance of aluminum alloy window usually needs to consider the following aspects: strength, reflected in the selection of aluminum alloy window profile material, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the window structure, whether the inner and outer frame structure of the window is tight; water tightness, mainly to check whether there is water accumulation and leakage phenomenon in the aluminum alloy window; Sound insulation, which mainly depends on the sound insulation effect of insulating glass and the durability of other window accessories such as opening and closing force, opening and closing durability, etc.
