The window is a necessary structure in the house, the window can block the wind, block the noise, and can give our home a sense of security.
A must for home life. The appearance of windows can even be traced back to primitive society. The ancients opened holes in natural caves to learn from, which is the most primitive form of windows.
Since then, with the renewal of architectural forms, the forms of windows have also continued to develop. At present, the commonly existing windows in the market can be divided into three categories according to their materials: aluminum alloy windows, plastic steel windows and aluminum-clad wood windows.
Among them, aluminum-clad wooden windows are the most expensive. Although the price of aluminum-clad wooden windows is much higher than that of aluminum alloy windows and plastic steel windows, the share of aluminum-clad wooden windows in the window market continues to grow. What makes everyone willing to spend more What about the price of aluminum-clad wooden windows? Why do aluminum-clad wooden windows belong to the "noble" family? Let me take you to find out today:
1.What is aluminum-clad wooden window
To put it simply, aluminum-clad wooden windows are based on wooden windows with external aluminum materials, so that the inner wood and the outer aluminum are harmoniously unified. The inner wood structure matches the natural style of interior decoration, and the outer aluminum structure complements the building facade. , Strengthen the performance of pure wooden windows to resist the sun, wind and rain, so as to relieve people from all worries about wooden products.
2.performance advantage
Thermal 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 the wood frame is only 1.3, which is far better than the 3.0 of aluminum windows. Compared with 2.2 of plastic windows, the composite frame of aluminum-clad wood window has stronger thermal insulation performance.
Environmental protection: According to data, the energy consumption ratio of aluminum alloy windows, plastic steel windows, and aluminum-clad wood windows is 20:8:1. The aluminum alloy window frames are derived from non-renewable bauxite soil, and plastic steel windows are derived from non-renewable petroleum. Because wooden windows are natural life forms, the source is renewable wood, as long as they are reasonably exploited, they are inexhaustible resources.
Fireproof: The melting point of aluminum alloy is 650℃. Even if fireproof glass is used, it will lose its function due to the disintegration of the frame and cause the glass to fall;
The melting point of PVC is 120-210℃, and it will produce toxic gas in case of fire, and plastic steel windows cannot be made into fireproof windows;
The ignition point of wood is 250°C, but due to its good heat insulation and the carbonized layer formed after burning, it will not transmit the high temperature to the unburned side to cause other objects to burn.
Life: Plastic steel windows and aluminum alloy windows are mainly vulnerable to accessories: casters, switches, and plastic strips for pressing glass. If you buy windows from regular manufacturers and the accessories are also high-quality products, these accessories can last for 7 or 8 years. , But it is more troublesome to replace. Another disadvantage of plastic-steel windows is aging. Under the action of ultraviolet rays, the macromolecular chains of the high-molecular-weight PVC resin will break, causing the surface of the material to lose luster, discoloration and powdering, and the mechanical properties of the profile are reduced. Plastic-steel windows are easily deformed by heat, become brittle when exposed to cold, and have poor dimensional and shape stability. They are prone to not open, close, and expose to air.
Aluminum-clad wooden windows have a high industry threshold. Regular manufacturers have large-scale imported processing equipment, such as wood optimization cutting, spraying production lines, aluminum CNC cutting production lines, etc., with high technical content, high processing accuracy, 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, regardless of individual villas (villa decoration renderings) residences or some protected buildings, aluminum-clad wooden windows have gone through a hundred years, although they are a bit old, they are still open and in normal use.
Home decoration: Although the colors of plastic steel windows and aluminum alloy windows are richer than before, they can even be made to imitate the texture of wood, but compared with aluminum-clad wooden windows, they are cold and dull, and the visual and tactile experience is poor. The interior side wood of the aluminum-clad wooden window has a unique natural texture, gentle and cordial, which complements the solid wood furniture in the interior, and meets the psychological needs of modern people who admire nature and pursue return. Friends who like wooden decoration styles , As long as economic conditions permit, we will not miss the selection of aluminum-clad wooden windows.
After-sales service: Plastic-steel windows and aluminum alloy windows due to the low industry threshold and irregular industry development, most of the domestic quality is not good enough, and there is no perfect after-sales service system. If you choose an imported brand, although the product quality is better, the after-sales service is beyond reach. The quality of service depends on the management level and ability of its domestic agents.
From the above points, we can probably understand why aluminum-clad wooden windows are expensive. At present, due to economic constraints, among a considerable number of consumers, plastic steel windows and aluminum alloy windows are still their first choice products. It is understood that my country's energy-saving standards for doors and windows (door and window decoration renderings) lag behind those of Europe for 20 years. The improvement of energy-saving standards for doors and windows and the elimination of some small workshops without technological content have become the top priority for ensuring the interests of consumers; another In terms of products, aluminum-clad wooden windows, which were once positioned as high-end consumer groups, have gradually entered the homes of ordinary people with the increase in product industrialization, cost reduction, and expansion of sales channels, so that more people have the ability to buy and have the opportunity to enjoy .
