There are many kinds of window opening methods on the market, such as sliding windows, casement windows, and swinging windows. According to the reporter's understanding, the difference in the way of opening the window, the price difference is also very large, especially the flat hanging window is the most expensive. But these kinds of windows also have their own characteristics. Which opening method is more suitable in different rooms and usage requirements?
The casement window is generally divided into two types: inner flat opening and outer flat opening. The wind pressure resistance, sealing performance and heat preservation are good, but the inner opening window needs to occupy the indoor space when opening; and for safety reasons, seven Outside the floor is not allowed to use the open window. The flat hanging window is a high-grade window with a lower hanging function on the basis of the casement window. The profiles and glass used are the same as the casement window, but the hardware is different. The sliding window is the most common opening method. Although the wind pressure resistance and sound insulation effect are not as good as the casement window, the cost is low, and it does not occupy space when it is opened, and it is convenient to manufacture and install than the casement window.
When choosing the windowing method, consumers need to make decisions based on their own needs. For example, in the balcony area, if the balcony itself is not insulated or the door is connected to the window, you don't need to consider the insulation performance too much, you can directly choose the sliding window; the kitchen is small and needs to be ventilated smoothly, you can also choose the sliding window. If you choose the way to open, consumers should also consider whether to open it completely and whether the hand is enough; in addition, in places where people such as balconies, walkways, etc. often walk, it is best not to install the inner window to avoid the window. An accident occurred after the opening. In addition, according to the relevant regulations of the state, houses with more than 7 floors cannot be opened outside.
In the heat loss of the outer protective structure of the entire room, the heat dissipation of the doors and windows accounts for about 50%. If energy is to be saved, the doors and windows are an aspect that cannot be ignored. The plastic steel window that people often say should be called plastic window. It is a building energy-saving product promoted by the state. It can maintain the thermal environment of the living room and achieve the effect of less heating in winter and room temperature in summer.
But there are also fake products in plastic windows. Since 2002, many small enterprises that have failed to meet the standards have launched plastic window projects, resulting in uneven products in the market. There are many products with poor quality. Consumers need to pay attention to screening when choosing.
So what should consumers pay attention to when they buy? They will not be "fudged"? Experts have introduced some problems and methods of identification of products in the market.
Selection articles: vigilance low quality products
Profile: mainly look at flexibility
Among the materials of the profile, calcium carbonate is relatively cheap, and some small manufacturers use calcium carbonate in large quantities, which makes the profile very brittle, cold and easy to crack, and even tear. Some profiles are small and thin, which also leads to a decrease in stiffness and affects wind resistance and Other properties. When choosing, consumers can take a look at their hand to see how flexible they are.
Accessories: thickness not less than 1.5mm
Using inferior hardware may result in poor switching within a year. The price difference of the sealing strip can reach more than 10,000 yuan per ton. The use of quality products will lead to shrinkage, hardening and cracking of the strip within one year. Some manufacturers do not even add reinforced steel bars to the profiles, or the thickness of the steel bars is insufficient, which will lead to a significant reduction in the life of the profiles. Reinforced steel is used to improve the wind pressure resistance of windows, and the thickness should be no less than 1.5mm. Plastic windows with steel added have a certain weight, which consumers can use as a criterion.
Glass: requires two layers of glue
