Aluminum alloy doors and windows as home decoration process supplies, related to the safety of the family, so the purchase of aluminum alloy doors and windows must be careful! We must know that the market of aluminum alloy doors and windows is uneven. If we choose the inferior aluminum alloy doors and windows carelessly, it will be very troublesome. It is not as good as our common quality problems such as air leakage and water mixing in doors and windows.
So what do we need to know about the purchase of aluminum alloy doors and windows? How to choose high quality aluminum alloy doors and windows? What should be considered?
1、 Energy saving of heat preservation
Choose and buy aluminum alloy doors and windows must choose thermal insulation energy-saving aluminum alloy doors and windows, how to choose? There are so many aluminum alloy doors and windows companies. Try to choose brand system aluminum alloy doors and windows. Generally speaking, the thermal insulation and energy saving of aluminum alloy doors and windows mainly depends on the following points:
The heat conduction coefficient K of aluminum aluminum alloy doors and windows with broken bridge made of Al Si Mg alloy is less than 3W / m2. K, which reduces the heat loss by half and reduces the heating cost by about 30%. Low quality profiles on the market use recycled aluminum materials, reprocessing, mixed with impurities, low price, not only can not play a role in heat preservation and energy saving, but also has a short life.
Compared with single glass, insulating glass has lower conductivity, which effectively reduces the heat conduction through aluminum alloy doors and windows.
3. Sealing strip
The service life and sealing performance of high-quality sealing strip are naturally higher than that of ordinary sealing strip.
2、 Water resistance
When it comes to rainstorm and typhoon weather, windows have to undergo a test of fear. The so-called good-looking aluminum alloy doors and windows are the same, and the poor quality aluminum alloy doors and windows are leaking air and rain. Choose a good aluminum alloy doors and windows, not only in price, quality is excellent, in the process also need to meet the standard. The waterproof principle of aluminum alloy doors and windows is to use the principle of pressure balance to design the structural drainage system, the sliding design of the inclined ladder type, with a drain outlet, the drainage is smooth and the water tightness is good. Therefore, Aowei doors and windows think that when selecting doors and windows, we should choose the brand aluminum alloy doors and windows with good sealing and waterproof technology, and more importantly, we should select windows with scientific drainage, so as to successfully keep the rain out of the window and enjoy the rain with peace of mind.
3、 Fire resistance
For high-rise residents, it is recommended to choose aluminum alloy doors and windows with fire-proof characteristics made of glass and window frames. They are not afraid of 10000, but afraid of emergency. In case of fire, the fire-proof windows can reserve at least one hour for rescue workers, and the fire-resistant windows can last for half an hour. These precious time is equivalent to borrowing one's life from heaven, leaving no regrets at the critical moment.
4、 Sound insulation effect
When selecting aluminum alloy doors and windows, hollow glass or three glass should be selected as far as possible, the inner and outer channels should be sealed, and EPDM sealant strip should be used at the joint of frame glass and profile to strengthen the sealing of windows, so as to achieve the purpose of sound insulation. Generally, when the sound insulation loss reaches 30-40db, the residents within 50 meters on both sides of the expressway will not be disturbed by noise, and the surrounding downtown can also ensure the indoor quiet and warm.
5、 Price of aluminum alloy doors and windows
Look at the price of aluminum alloy doors and windows, high-quality aluminum alloy doors and windows prices are generally more expensive, the so-called expensive value for money. No one wants to buy back the things will soon be treated as garbage, choose doors and windows must choose the formal aluminum alloy doors and windows manufacturers, to prevent the purchase of shoddy, big hidden danger products.
