Windows are a must for home life. The appearance of the window can even be traced back to the primitive society. The ancients opened holes in the natural caves to find out the most primitive window form. Since then, with the renewal of the architectural form, the form of the window has also been continuously developed. Currently, the windows that are commonly found on the market can be divided into three categories according to the material: aluminum alloy window, plastic steel window and aluminum-clad wood window. Among them, the price of aluminum-clad wood window is the most expensive. The price of aluminum-clad wood window is usually about 2,200 yuan per square meter. The quality is better and the after-sale guarantee is more than 2,500 yuan. As for the price below 2,000 yuan, it is basically "high imitation", the effect is similar to the "buyer show", it is not in our discussion. Although the price of aluminum-clad wood windows is much higher than that of aluminum alloy windows and plastic-steel windows, the share of aluminum-clad wood windows in the window market is growing. What makes everyone want to pay more for aluminum-clad wood windows? Why do the wooden windows belong to the "expensive" family? Let Xiaobian take everyone to find out today: 1. What is aluminum-clad wood window? To put it simply, the aluminum-clad wood window is based on the wooden window, and the aluminum material is attached to make the inner wood and the outer aluminum harmoniously unified. The inner wooden structure is matched with the natural style of the interior decoration, and the outer aluminum structure and the building facade complement each other. It strengthens the performance of pure wood windows, sun exposure, wind and rain, and eliminates all concerns about wood products. Need to be reminded that there is a product on the market that is very similar to the appearance of aluminum-clad wood window - wood-aluminum composite window, but its cost is far lower than aluminum-clad wood window, and the performance indicators are also far from each other. The two have the essential difference in structure: aluminum-clad wood window, the main body is wood and aluminum, which is more wood and less aluminum. The wood-aluminum composite window is less wood and more aluminum. It is actually a fake wooden window. ", is an aluminum alloy window with decorative wood panels on the inside! Consumers should pay special attention when purchasing. 2, performance advantages Insulation: Compared with aluminum alloy windows and plastic steel windows, aluminum-clad wood windows have outstanding advantages in thermal insulation performance. This is because the heat transfer coefficient of wood frame is only 1.3, which is far superior to aluminum window 3.0. And plastic window 2.2, and aluminum-clad wood window composite frame, thermal insulation performance is stronger. Environmental protection: According to the data, the energy consumption ratio of aluminum alloy window, plastic steel window and aluminum-clad wood window processing is 20:8:1, aluminum alloy window frame source is non-renewable aluminum ore, and plastic steel window source is non-renewable oil. Because wooden windows are natural living organisms, the source is renewable wood. As long as it is reasonably mined, it is an inexhaustible resource. Fire prevention: The melting point of aluminum alloy is 650 ° C, even if fire-resistant glass is used, it will lose its effect due to the glass falling off due to the disintegration of the frame; The melting point of PVC is 120-210 ° C, which will produce toxic gases in case of fire, and plastic steel windows cannot be made into fireproof windows; The wood has a burning point of 250 ° C, but due to its good heat insulation and carbonization layer formed after combustion, the high temperature is not transmitted to the other side that is not burning, causing other articles to burn. life: Plastic steel windows and aluminum alloy windows are mainly fragile accessories: casters, switches, pressed glass strips, if you buy a window made by a regular manufacturer, accessories are also high-quality products, these accessories can be used for 7 or 8 years, but It is more troublesome to replace. Another shortcoming of plastic-steel window is aging. Under the action of ultraviolet light, the polymer PVC resin breaks the macromolecular chain, causing the surface of the material to lose its luster, discoloring and pulverizing, and the mechanical properties of the profile are degraded. Plastic-steel windows are susceptible to heat deformation, cold and brittle, and poor dimensional and shape stability. They are prone to open, closed, and exposed air. Aluminum-clad wood window, high industry threshold, regular manufacturers have large-scale imported processing equipment, such as wood preferred cutting, spraying production line, aluminum CNC cutting production line, etc., high technical content, high processing precision, wood, hardware, rubber strips, etc. Most of the raw materials are imported and the quality is better, so its life span is almost as long as the building itself. In Europe, whether it is a personal villa or a protective building, the aluminum-clad wood window has gone through a hundred years, although it is somewhat outdated, the switch is still flexible and in normal use. Home Decoration The color of the plastic-steel window and the aluminum alloy window is richer than before, and can even be made into the texture of the wood. However, compared with the aluminum-clad wood window, it is cold and dull, and the visual tactile experience is poor. The interior wood of aluminum-clad wood window has natural unique texture, gentle and intimate, and complements the indoor solid wood furniture. It satisfies the psychological needs of modern people who admire nature and pursues return. Friends who like wood decoration style, as long as economic conditions allow Will not miss the aluminum-clad wooden window. After sales service Due to the low threshold of the industry and the unregulated industry development, the plastic steel window and aluminum alloy window are mostly closed, and there is no perfect after-sales service system. If you choose an imported brand, although the product quality is better, but the after-sales is beyond the reach, the quality of service depends on the management level and ability of its domestic agents. From the above points, I can probably understand why aluminum-clad wood windows are expensive. At present, due to economic constraints, plastic steel windows and aluminum alloy windows are still their preferred products among a considerable number of consumers. It is understood that China's door and window energy-saving standards lag behind Europe for 20 years, improve the energy-saving standards for doors and windows, and eliminate some small workshops without technology content, which is the focus of ensuring the interests of consumers; on the other hand, aluminum-clad wooden windows Such products, which have been targeted at high-end consumer groups, have gradually entered the homes of ordinary people as the degree of industrialization of products has increased, the cost has decreased, and the sales channels have expanded, so that more people have the ability to purchase and have the opportunity to enjoy.
