What do you know about the difference between aluminum-wood composite doors and windows and aluminum-clad wooden doors and windows?
Aluminum-wood composite doors and windows represent the advanced level of German doors and windows technology at this stage. It gathers a variety of applicable subject technical achievements such as wood manufacturing and processing technology, metal processing technology, surface treatment technology, sealing material manufacturing technology, and material mechanics, and is popular with customers for its modern, stylish, solid and distinctive features.
The concept of aluminum-wood composite was originally introduced by Germany, and some domestic manufacturers processed this concept, and imitation of aluminum-wood composite doors and windows formally, so today's aluminum-wrapped wood is used. The real aluminum-wood composite doors and windows are the perfect combination of the excellent performance of wood and aluminum corrosion resistance, high hardness, a high-end energy-saving and environmentally friendly doors and windows. Aluminium-wood composite doors and windows have a double decoration effect. The "inner wood" style creates the warmth and comfort of the interior, and the "outer aluminum" structure of the exterior facade gives a modern, stylish aesthetic.
The main structure of aluminum-wood composite doors and windows is the same as that of solid wood. From the aspect of appearance, those who do not understand will think that there is no difference. This is also the astuteness of those manufacturers. However, the mystery is after all a mystery. The real aluminum-wood composite doors and windows not only maintain the style of solid wood doors and windows, but also have rich and colorful colors of aluminum alloy coated with fluorocarbon or electrostatic spraying, and have excellent physical properties, excellent energy-saving effect and strong weather resistance. Scientifically designed nodes increase the overall performance of doors and windows. Its excellent insulation performance and airtight performance, excellent fire performance, aluminum and wood composite doors and windows the biggest feature is insulation, energy saving, anti-wind. It is wrapped in a layer of aluminum alloy in addition to the solid wood, so that the doors and windows and the architectural style of the facade integration, and play a role of waterproof protection of the form of wood frame. When extreme heat becomes unbearable, it can block outdoor heat and reduce the loss of indoor air-conditioning. In the cold winter, it will not freeze or dew, and noise will be kept out of the window. Germany has strict requirements on the structure, standard system and connection method of aluminum-wood composite doors and windows. However, domestic aluminum wraps are usually connected by mechanical means such as screwing or welding, and the number of corners is a group or no corners. Screwing and welding have a destructive effect on wood and aluminum profiles themselves, and the stability and thermal insulation effects can be imagined.
The aluminum-wood composite doors and windows have an aluminum wall thickness of 2.2-2.4 mm, while aluminum-clad wood has an aluminum alloy wall thickness of approximately 1 mm. Aluminium wrap wood is only an imitation of aluminum and wood composites. The window strength depends on solid wood only, and the window strength of aluminum-wood composite can reach 1+1>2. That is, the strength of the window is greater than that of aluminum alloy and solid wood. with. Why can this effect be achieved? The reason is that in addition to the protection of wood, aluminum alloys increase the overall strength through a scientific combination. This cannot be imitated and surpassed.
1 Wood and aluminum alloy connection
Many domestic manufacturers stick wood directly to aluminum alloy frames. This practice is extremely wrong. It is well known that the linear expansion densities of wood and aluminum alloys are not the same. When they are affected by temperature, they will inevitably cause the connection failure between the two.
2 Effect of condensed water on aluminum alloy surface
When the indoor humidity is relatively large, the inner surface of the aluminum alloy will condense. If wood and aluminum alloy are directly bonded at this time, the wood will inevitably be corroded.
3 wood choice
The use of finger-joint materials is preferred for wood, and it is the best in both end-use performance and price. There are two main types of finger joints: vertical and flat connections or docking. The difference between these two types of connection is the difference in appearance and shape characteristics and the difference in the processing technology of the workpiece.
With vertical finger joints, where the wide face of the wood is the visible surface of its shape, the shape of the plane connection can only be seen from the side of the plate. Vertical connections are generally popular in Europe and are used for the production of structural beams, which are used extensively in the construction industry. In accordance with strict process standards, finger-joint materials applied to engineering structures should have extremely high tensile strength, and therefore have stronger properties than large-sized solid wood pieces.
4 product protection
In order to facilitate the installation of the entire window, after the timber is required to be connected to the entire frame, it will be buckled after the decoration is finally completed. This avoids the damage to the wood caused by poor crossover operations.
