[China Aluminum Network] Windows are essential for home life. The appearance of the window can even be traced back to the primitive society. The ancients made holes in the natural caves, which are the more primitive forms of windows.
Since then, with the renewal of architectural forms, the forms of windows have continued to develop. Currently, the windows that are commonly found on the market can be divided into three categories according to their materials: aluminum alloy windows, plastic steel windows, and aluminum-packed wooden windows.
Among them, aluminum-clad wooden windows are relatively expensive. Generally, the prices of aluminum-clad wooden windows are generally around 2,200 yuan per square meter, and the quality is better and the after-sale protection is more than 2,500 yuan. As for prices below RMB 2,000, they are basically "high imitations." The effect is similar to that of the "buyers show." It is beyond our scope of discussion. 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 wood windows in the window market continues to grow. What makes everyone willing to spend more for aluminum-clad wood windows? Why are aluminum-clad wooden windows classified as "expensive"? Let Xiaobian take you to find out today:
1, what is aluminum package window?
In simple terms, aluminum-clad wooden windows are based on wooden windows. Aluminum is externally connected, so that inner wood and outer aluminum are harmonized. The inner wood structure matches the natural style of interior decoration. The outer aluminum structure complements the outer facade of the building. Enhance the performance of pure wood windows against sun exposure, wind and rain, etc., eliminating all concerns about wood products.
What needs to be reminded is that there is a wood-aluminum composite window that has a very similar appearance to aluminum-clad wooden windows on the market. However, its cost is much lower than that of aluminum-clad wood windows, and the performance indicators are far from each other. There are essential differences between the two structures: aluminum-clad wooden windows, the main body is wood, and the external aluminum material is more wood and less aluminum; while the wood-aluminum composite window is less wood and more aluminum, which is actually a “false wood windowâ€. †is an aluminum window with a decorative plank hanging inside! Consumers should pay special attention when buying.
2. Performance advantages 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 wood frame heat transfer coefficient is only 1.3, far better than The 3.0 of the aluminum window and 2.2 of the plastic window, while the aluminum-clad wood window composite frame, the insulation performance is stronger.
Environmental protection: According to statistics, the ratio of energy consumption for aluminum alloy windows, plastic steel windows, and aluminum-clad wood windows is 20:8:1. The aluminum alloy window frame is derived from non-renewable aluminum ore, and the plastic-steel window is derived from non-renewable petroleum. Because wood windows are natural living bodies, the source is renewable wood. As long as it is properly mined, it is an inexhaustible resource.
Fire protection:
The melting point of aluminum alloy is 650 °C. Even if fireproof glass is used, the glass will lose its function due to the disintegration of the frame body.
The melting point of PVC is 120-210 °C, and it will produce toxic gases in case of fire, and the plastic window cannot be made into fireproof windows;
The ignition temperature of wood is 250°C, but because of its good thermal insulation and the formation of a carbonized layer after combustion, it does not transfer high temperatures to the other side of the non-combustion, causing other items to burn.
life:
Plastic windows and aluminum alloy windows are mainly vulnerable to attachments: casters, switches, and glass-pressed plastic strips. If you buy windows made by regular manufacturers and accessories are quality products, these accessories can be used for 7 or 8 years, but It is troublesome to replace it. Another shortcoming of plastic steel window is aging, macromolecule PVC resin under the action of ultraviolet light, macromolecular chain fracture, the surface of the material loses luster, discoloration powder, the mechanical properties of the profile is reduced. Plastic-steel windows are susceptible to thermal deformation, brittle to cold, and poor in dimensional and shape stability. They are prone to open, closed, and open air.
Aluminum-clad wooden windows, high industry threshold, regular manufacturers have large-scale import processing equipment, such as wood cutting, spraying production line, aluminum CNC cutting production line, high technology content, high precision machining, wood, hardware, plastic strips, etc. Most of the raw materials are imported and the quality is better, so its life is almost as long as the building itself. In Europe, whether it is individual villas or some protected buildings, aluminum-clad wood windows have passed through for a hundred years. Although they are somewhat old, they are still flexible in normal use.
Although the colors of the home-decorated plastic windows and aluminum alloy windows are richer than before, they can even be made to resemble the texture of the wood. However, compared with aluminum-clad wooden windows, the ice-cooled panels have poor visual tactility. The interior wood of aluminum-packed wooden window has natural special texture, gentle and warm, and it complements the interior solid wood furniture, satisfying the modern people's psychological needs of advocating nature and pursuing return, and friends who like wood decoration style, as long as the economic conditions permit Will not miss the election of aluminum package window.
After-sales service Plastic steel windows and aluminum alloy windows have low thresholds in the industry and the industry is not standardized. Most of the domestic quality is not closed, and there is no perfect after-sales service system. If you choose to import brands, although the product quality is better, but 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, we can understand why the aluminum package window is expensive. At present, due to the constraints of economic conditions, steel windows and aluminum alloy windows remain their preferred products among a considerable number of consumers. It is understood that China's energy efficiency standards for doors and windows lagging behind that of Europe for 20 years, raising the energy efficiency standards for doors and windows, and eliminating some small workshops without scientific and technological content, which are among the highest priority for ensuring the interests of consumers; on the other hand, aluminum-clad wooden windows In this way, products targeted at high-end consumer groups have gradually entered the homes of ordinary people as the degree of industrialization of products has increased, costs have been reduced, and sales channels have expanded, allowing more people to have the ability to purchase and have access to them.
