First of all, it can be seen from the literal meaning that aluminium wraping wooden window is wrapped with aluminum alloy, while wood composite aluminum alloy is a combination of wood and aluminum alloy.
Aluminum clad wood doors and windows aluminum part is in the outdoor Road, which is used to resist ultraviolet rays and various natural corrosion. Wood can have heat preservation, sound insulation and other effects indoors.
Wood composite aluminum alloy has less wood materials, so the insulation effect is worse than that of aluminum-clad doors and windows, and the sound insulation effect is also like this.
When buying doors and windows, we must be cautious about the combination of wood and aluminum, and choose suitable doors and windows according to personal actual needs.
There are two types of aluminum-Wood combined doors and windows, one is aluminum clad wood doors and windows, the other is wood-clad aluminum doors and windows, each of which has a hundred of its value, although they are aluminum-Wood combined doors and windows, but there are also some differences. Today, I will introduce these differences to you. 1. The concept of senying aluminum-wood composite was originally introduced by Germany, and domestic manufacturers processed this concept, so there was aluminum-clad wood for today. 2. From the appearance and form, people who don't know how to do it will think there is no difference, which is also the shrewdness of domestic manufacturers. But mystery is mystery after all. If you don't answer the instructions of the insiders, it's hard for you to understand what's going on. Aluminum and wood composite recommend liangmu Road and Huaxing. 3. Aluminum clad wood doors and windows is a window with Wood as the main profile, that is, wood and aluminum are good; Wood-clad aluminum window is a window with aluminum inner material as the main profile, that is, more aluminum and less wood. 4. Aluminum is a good conductor of heat, so the effect of Wood-coated aluminum window on thermal insulation is slightly worse; The main profile of aluminium wraping wooden window is wood, so its thermal insulation sealing effect is much better.
Aluminum-wood composite doors and windows, aluminum clad wood doors and windows and wood-pasted aluminum doors and windows are the combination of aluminum and wood profiles, but the three are by no means the same grade of doors and windows products, so what are the essential differences between the three?
The first is the conceptual difference. The concept of aluminum-wood composite doors and windows was originally introduced from Germany. In Germany, this form of doors and windows has a strict standard system and related supporting facilities. Domestic manufacturers simply imitated it in appearance form and named it "Aluminum clad wood doors and windows". There seems to be no difference between the two, but in fact, there is a big difference in many aspects such as technology, details and performance. Without the guidance of professionals, it is difficult for you to understand the concept of aluminum-wood composite.
The second is the difference between the system standards. The aluminum-wood composite doors and windows adopt the German IV68 standard system, and IV68 is the standard of the German doors and windows Association. He has strict regulations on the standards of doors and windows. Many domestic manufacturers have not really understood the connotation of IV68, so they simply think that as long as the cross-section thickness is 68mm, it is in line with iv68. In fact, it is not. Since it is a door and window system, it must have many interrelated factors. In Germany, IV68 can only be called if these factors are available at the same time. In addition, since IV68 is a German standard, only German door and window manufacturers should meet this standard. Other countries can only refer to or learn from this standard, formulate a standard system that conforms to the national conditions of the country. However, at present, China has not issued relevant standards for doors and windows in the form of combination of aluminum and wood. Each manufacturer only has its own system according to its simple understanding of IV68. So you can find that there are many so-called IV68 doors and windows in the domestic market, but each one is different.
Finally, there are differences in technology, such as degreasing technology and water-based paint process. In addition, Germany has strict requirements on the structure and connection mode of aluminum-wood composite doors and windows.
1. Aluminum-wood composite doors and windows are composed of aluminum and wood profiles. All wood is treated by anti-corrosion degreasing, which has the characteristics of high strength, difficult deformation, clear texture, etc, all wood adopts water-based paint and dipping process, and the wood surface is smooth, flexible and elastic. At present, the best degreasing technology is in Europe and Germany, while there is no degreasing kiln in China, so there is no degreasing technology, so there is no way to use water-based paint or dip paint, there will be color difference when using paint for wood without degreasing.
2. The connection mode between aluminum and wood. Aluminum-wood composite doors and windows adopt plastic racket buckle and aluminum suspension buckle, and adopt three sets of angle codes for scientific connection. However, domestic aluminum clad wood doors and windows usually adopt mechanical connection methods such as screw connection or welding, and the number of angle codes is one group or no angle codes. Screw joint and welding have destructive effect on wood and aluminum profile itself, and the stability and heat preservation effect can be imagined.
3. Window strength. 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 doors and windows is only an imitation of the form of aluminum-wood composite doors and windows, the strength of window forming depends only on solid wood; Wood-pasted aluminum doors and windows take aluminum alloy as the main body, and wood only has the decorative effect of appearance, while the strength of window forming of aluminum-wood composite doors and windows can reach 1 1>2. The so-called "1 1>2" means that the strength of the 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 something that domestic manufacturers cannot imitate and surpass.
