At present, there are many kinds of window opening methods on the market, such as sliding windows, casement windows, flat hanging windows, and the like. According to the reporter's understanding, the difference in the way of opening the window is quite different from the price, especially the most expensive of the hanging windows. But these kinds of windows also have their own characteristics. Which opening methods are more suitable for different rooms and usage requirements? Casement windows are generally divided into inner and outer flat open, the wind pressure strength, sealing, and heat insulation are all better, but the open windows need to occupy the interior space when open; and for security reasons, seven Above the floor is not allowed to use outside the window. Swing lower hanging window is a high-grade window with hanging function added on the basis of the flat window. The used profile and glass are the same as the casement window, but the hardware is different. Sliding window is the most common way to open, although the wind pressure strength, sound insulation effect is not as good as flat windows, but the cost is low, does not take up space when opening, and its production and installation than the open window to facilitate. When choosing a windowing method, consumers need to make decisions based on their own needs. For example, in the balcony area, if the balcony itself does not do insulation or the interior is a door with a window type, you do not have to consider too much of its insulation properties, you can directly select the sliding window; kitchen due to the narrow space and the need for smooth ventilation, you can also choose sliding window If you choose to open the way outside, consumers still need to consider whether it is fully open, whether the hand is available; In addition, in the balcony, walkways and other people often walk position, it is best not to install the internal window, avoid windows Accidents occurred after the opening. In addition, according to the relevant regulations of the country, houses over 7 floors cannot be opened outside. In the heat loss of the external protection structure of the whole room, the heat dissipation of the doors and windows accounts for about 50%. If energy is to be saved, doors and windows are not to be neglected. The Plastic Window that people often say should be called a plastic window. It is a building energy-saving product promoted and used by the country. It can maintain the thermal environment of the house, achieve less heating in the winter and be suitable for the room temperature in the summer. However, there are fake and inferior products in plastic windows. Since 2002, many small enterprises that have failed to meet the standard have launched plastic window projects. As a result, the market products are mixed, and there are many products with poor quality. Consumers need to be careful when choosing. So what should consumers pay attention to when they buy? It's an expert who introduced some of the problems that may exist in some products in the market and how to identify them. Choice articles: alert price low quality product Profiles: mainly see the flexibility In the material of the profile, calcium carbonate is relatively cheap, and some small manufacturers will use calcium carbonate in large quantities, resulting in the profile being brittle, cold and easy to crack, and even tearable. Some profiles are small and thin, which can also lead to reduced stiffness and affect wind pressure resistance and other properties. At the time of selection, consumers can take a sip and see how flexible it is. Accessories: thickness not less than 1.5mm Using inferior hardware may result in poor switching within one year. The spread of sealant strips can reach more than 10,000 yuan per ton. The use of quality products will cause shrinkage, hardening and cracking of the strips within one year. Some manufacturers do not even add reinforced steel bars in the profiles, or the thickness of the steel bars may lead to a significant reduction in the life of the profiles. Reinforced steel is used to improve the wind resistance performance of the window. The thickness should not be less than 1.5mm. After adding steel, the plastic window has a certain weight, and consumers can use this as a criterion. Glass: Two layers of glue required In general, glass requires two layers of glue: one for bonding glass and a frame, and the other for sealing between glass and insulating water vapor and air. However, some manufacturers only made a layer of seals, which caused the windows to leak soon after use, and the insulation effect was greatly reduced. This link requires the manufacturer of the window to have the appropriate machinery and equipment. When selecting the window manufacturer, consumers can ask the manufacturer whether the glass is customized by a professional manufacturer or produced by oneself. If it is produced by oneself, it needs to have an insulating glass production line and a machine wiper. And so on, as far as possible do not choose artificial wipe, through these issues to determine whether the manufacturers have the appropriate production capacity. Safeguarding equity through contracts Because ordinary consumers can not accurately identify the quality of the window profiles and other aspects, and the assembly and installation of the windows will affect the quality of the latter period, Xiaobian recommends that consumers choose the window assembly factory with a certain production capacity. The assembly plant should have dedicated equipment and tools for each major process. At present, there are many plastic window manufacturers in the market, and some manual workshops use manual welding machines to produce, and cannot guarantee product quality. When choosing a manufacturer, it is best to be sure that it has the corresponding production equipment, such as automatic welding machine, clearing machine, glass bead saw and so on. Consumers should detail the relevant content when they sign a contract with the assembly manufacturer to safeguard their own rights and interests. Such as in the one-year warranty period: 1. Profiles can not appear discoloration, chalking phenomenon (hand touch profiles, white powder on the profile); 2. Switch function will not change, the switch is still flexible, not blocked; 3 The glass can not appear condensation, ash, atomization and other phenomena.
