What kind of windows are of good quality?
Solid wood window
Solid wood window refers to the window with wood as the frame material, which has good sound insulation effect, but it has high cost and is easy to deform. Now there are some wood-aluminum composite windows and wood-plastic composite windows on the market, which have improved these shortcomings to some extent.
aluminium alloy window
There are 70 series and 90 series of aluminum alloy sliding frames, and the aluminum alloy sliding window used to close the balcony should be no less than 70 series. Aluminum alloy has high hardness, not easy to scratch, smooth surface, dirt resistance and easy cleaning. But at the same time, its thermal conductivity is too strong and its thermal insulation performance is poor.
Plastic steel window
The middle is a steel structure, and the outside is a plastic extrusion profile, which is generally white. Sticking PVC film on the surface can change color, but the film will change color and fall off after a long time; It has good sound insulation, heat insulation, fire prevention and heat preservation functions, good air tightness, water tightness and corrosion resistance, and low price. The disadvantage is that its cross section is larger and its lighting performance is slightly worse than that of aluminum alloy windows.
Broken Bridge Aluminum
Broken bridge aluminum is a kind of aluminum alloy, but it improves the defect of poor heat insulation of ordinary aluminum alloy. However, due to its complicated design, the construction and production costs have greatly increased. At present, the commonly used aluminum alloy window frames are not as good as the traditional steel window frames. Of course, broken bridge aluminum has replaced aluminum alloy, aluminum-magnesium alloy and plastic steel because of its good thermal insulation and sound insulation performance and strong formability, and has become the mainstream choice in the current home improvement market.
