Modern home decoration, in order to ensure the beauty and practicability of loving home, aluminum alloy doors and windows are generally used for exterior wall window decoration. However, there are many brands of doors and windows in the market, and the price and quality are uneven. How can we choose high-quality aluminum alloy doors and windows?
Aluminum alloy doors and windows it can be divided into ordinary types aluminum alloy doors and windows and energy-saving aluminum alloy doors and windows . Energy saving aluminum alloy doors and windows it is made of insulated aluminum alloy profiles and energy-saving glass( hollow glass, LOW-E glass, heat absorbing glass, coated glass, vacuum glass, etc.) made.
1. High quality insulation broken bridge aluminum alloy doors and windows what are the characteristics
good atmospheric corrosion resistance, high comprehensive performance, long service life and good decorative effect are the preferred products for high-grade building windows.
2. What is heat insulation broken bridge aluminum alloy doors and windows ?
Heat insulation broken bridge aluminum alloy doors and windows is in the old aluminum alloy doors and windows on the basis, the improved Windows introduced to improve the thermal insulation performance of doors and windows mainly divide aluminum alloy materials into two different parts inside and outside through enhanced nylon barrier, thus playing the role of blocking heat conduction.
3. How to choose insulation broken bridge aluminum alloy doors and windows ?
Want to choose the best insulation broken bridge aluminum alloy doors and windows , must start from the following two aspects
material: high quality aluminum alloy doors and windows the thickness, strength and oxide film of the aluminum profile used shall conform to the relevant national standards, which are generally wall thickness.1.2 above mm, tensile strength per square mm157 cattle, yield strength per square millimeter 108 cow, oxide film thick10 micron.
4. How to check various aluminum alloy doors and windows the quality of the material?
4.1 the window frame should be clean, smooth and smooth, with no scratches or bumps on the large surface, and the profile is broken by five-opening welding.
4.2 complete hardware, correct location, firm installation and flexible use.
4.3 the contact between the glass sealing strip and the glass and the glazing rebate should be flat, and no curling or grooving should be allowed.
4.4 when the doors and windows are half closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.
4.5 the glass should be flat, installed firmly, and there should be no looseness. Single-layer glass should not directly contact the profile. The inner and outer surfaces of double-layer glass should be clean, without dust and water vapor, and the barrier should not be tilted.
4.5 the bead with sealing strip must be tightly attached to the glass, there should be no obvious gap at the joint between the bead and the profile, and the joint gap should be less than or equal1 MM.
4.6 the splicing materials should be closely connected with the window frame, and sealed with caulking paste at the same time, without shaking. The inner layer of reinforced steel should be fixed firmly with the opening at both ends.
4.7 the windows should be closed tightly.
4.8 the position of the drain hole should be correct, and it should be normal at the same time.
By learning the above 4 point, I believe everyone has a deeper understanding of how to choose high-quality aluminum alloy doors and windows. When buying doors and windows in home decoration in the future, they will choose aluminum alloy doors and windows with excellent brands.
