How to choose aluminum alloy doors and Windows correctly

For a long time, there are two directions for door and window products. One is a single aluminum alloy material as the main body, emphasizing the design-oriented "decorator", the other is the upgrade of wood aluminum, aluminum wood, aluminum-plastic process "technology flow", hoping to manufacture products through the system concept, to achieve temperature insulation noise reduction, energy saving and environmental protection comprehensive upgrade. In general, we divide the doors and Windows plate into system doors and Windows and aluminum alloy doors and Windows for easy comparison and selection. Today, we mainly talk about aluminum alloy doors and Windows.
Aluminum alloy doors and Windows are the most basic configuration of general housing, and they are also the most important factors affecting lighting, ventilation and comfort. With the development of The Times, house decoration, home installation of aluminum alloy doors and Windows is the trend of The Times, but the installation of aluminum alloy doors and Windows is more disputes, for example, in the installation, only to find that the aluminum alloy profile is not up to standard, the thickness is not enough and other problems, so in the decoration, to spend more thought to choose aluminum alloy doors and Windows, do not spend money! First of all, let's look at what problems will occur in ordinary aluminum doors and Windows?

1, doors and Windows are not level
After the doors and Windows are installed, there is a high and a low, uneven gap between the fan and the frame, and sometimes there is a problem that the upper width is narrow or the lower width is narrow.
2, welding feet open welding, profile fracture
Mainly because the installation personnel in the handling, loading and unloading, installation process does not pay attention to the result, serious will appear welding Angle welding, profile fracture and other consequences.
3, the seal is not tight
The middle or lower part of the door and window is not well glued, which will cause water to leak into the room.
4. Water leakage
There are dripping eaves at the door and window openings, and when transforming the balcony, some owners will move the doors and Windows outside and press onto the dripping eaves, and the rain will enter the gap between the window frame and the wall, and seep water from the upper part of the door and window.
5. The drainage hole is blocked
Plastic Steel Doors and Windows are equipped with drainage holes at the bottom, but the device will be blocked if you do not pay attention to it, once there is heavy rain, the water in the window frame will leak from the expansion plug of the device.

Basis for purchase: aluminum window purchase tips
1. Look at the material
The main materials of aluminum alloy doors and Windows generally include three aspects: aluminum profiles, glass, hardware, high-quality aluminum alloy doors and Windows are used to pay attention to the profile: only in terms of individual quality, tempered glass is better than ordinary glass.
In addition, regular or production license manufacturers, in the obvious parts of their aluminum alloy products are marked with product signs, including: manufacturer name or trademark, product name, product model or mark, manufacturing date or number. The words "Keep away from moisture", "Handle with care" and "upward" should be clearly marked on the packing case.
2, look at the processing
High-quality aluminum alloy doors and Windows, fine processing, smooth tangent, consistent Angle, there should be no obvious gaps in the splicing process, good sealing performance, smooth switching. Poor quality aluminum alloy doors and Windows, especially aluminum alloy outdoor doors and Windows products if the processing is not qualified, there will be sealing nature problems, not only air leakage and rain, but also under the action of strong winds and large external forces, the glass will burst and fall off.
3. Look at the appearance
There should be no obvious scratches, scratches, bruises and other defects on the surface of doors and Windows. There should be no obvious color difference on the coloring surface of adjacent components on doors and Windows. There should be no aluminum chips, burrs, oil spots or other stains on the surface of the window, and there should be no spilled adhesive at the assembly joints.

4. Look at performance
The performance of aluminum alloy doors and Windows usually needs to consider the following aspects: strength, reflected in the material selection of profiles, whether it can withstand ultra-high pressure; Air tightness, mainly reflected in the structure, doors and Windows of the inner fan and outer frame structure is tight; Water tightness, the main assessment of aluminum alloy doors and Windows whether there is water, leakage phenomenon; Sound insulation, which mainly depends on the sound insulation effect of insulating glass and other special sound insulation air-tight strip structure and the durability of other window Accessories such as opening and closing force, opening and closing durability.
5. Look at the price
Under normal circumstances, the price of high-quality aluminum alloy is about 30% higher than that of inferior aluminum alloy doors and Windows, inferior aluminum alloy doors and Windows usually use recycled aluminum extruded aluminum profiles containing a lot of impurities, the wall thickness of the aluminum profiles used is not up to standard, whether from the tensile strength or yield are much lower than the relevant national regulations, such aluminum alloy doors and Windows, In particular, aluminum alloy outdoor doors and Windows are very unsafe, so don't try to buy cheap and underestimate the personal safety of yourself and others.
There is little difference between the same grade broken bridge aluminum casement window and broken bridge aluminum sliding window in price, and the casement window is slightly higher than the sliding window.
