There are two kinds of terms in the domestic market, one is called "aluminum wood composite", the other is called "aluminum clad wood", and the latter is the title of domestic doors and windows.
There are essential differences between them
1. The concept of aluminum wood composite was first introduced from Germany, and domestic manufacturers processed the concept and imitated the aluminum wood composite doors and windows in form, so the aluminum clad wood today is produced. The main structure of aluminum wood composite doors and windows is consistent with that of solid wood doors and windows, which has all the advantages of solid wood doors and windows. The anti-aging performance of the exterior aluminum doors and windows is further enhanced through the design of the exterior aluminum doors and windows.
Aluminum wood composite doors and windows are the perfect combination of the excellent performance of wood and the characteristics of aluminum corrosion resistance and high hardness.
Aluminum wood composite doors and windows have double decorative effect, the "interior wood" style produces the warmth and comfort of the interior, while the "exterior aluminum" structure of the facade gives people a modern and fashionable aesthetic feeling. At the same time, its structure and performance have been greatly improved. It is a high-grade energy-saving and environmental protection door and window.
2. In terms of appearance and form, people who don't know the trade will think that there is no difference, which is also the smart point of domestic manufacturers. But mystery is mystery after all, if you have not been instructed by the industry, you are very difficult to understand what is going on. The aluminum doors and windows have excellent color and color of aluminum alloy and wood, which have excellent color and durability. Scientific design of the node, improve the overall performance of doors and windows. Its heat preservation performance and air tightness performance are excellent, and fire resistance is excellent. The biggest characteristics of aluminum wood composite doors and windows are heat preservation, energy saving and wind sand resistance. It is wrapped with a layer of aluminum alloy in addition to the solid wood, so that the doors and windows and the facade architectural style are integrated, and plays the role of waterproof and protecting the wood frame of the window. When the heat is unbearable, it can block the outdoor dry heat, reduce the loss of indoor air conditioning; in the cold winter, it will not freeze, condensation, but also keep the noise out of the window.
3. Germany has strict requirements on the structure, standard system and connection mode of aluminum wood composite doors and windows. For example, the connection of aluminum and wood, aluminum wood composite doors and windows use plastic snap buckle and aluminum suspension buckle, and use three groups of corner codes for scientific connection. It is usually welded with the same amount of angle wood in China. Screw joint and welding have destructive effect on wood and aluminum profile itself, stability and thermal insulation effect can be imagined.
4. The wall thickness of aluminum alloy of aluminum wood composite doors and windows is 2.2-2.4mm, while the wall thickness of aluminum alloy of aluminum clad wood is usually about 1mm. Aluminum clad wood is only the imitation of aluminum wood composite form, and the window forming strength only depends on solid wood, while the window forming strength of aluminum wood composite can reach 1 + 1 > 2. The so-called "1 + 1 > 2" means that the strength of the finished window is greater than the sum of the strength of aluminum alloy and solid wood. Why can this effect be achieved? The reason is that aluminum alloy profiles not only protect wood, but also increase the overall strength through scientific combination. This is what domestic manufacturers cannot imitate and surpass.
