Today, let's talk about the three mainstream door and window products in today's society:
The first aluminum clad plastic, the second broken bridge aluminum, the third aluminum clad wood
1. Aluminum-coated plastic products are the latest products on the market. This product comes from the upgrade and improvement of plastic steel (popular products in foreign markets are slowly introduced into China for upgrading and transformation). The weather resistance of aluminum, the thermal insulation of plastic, and the structural strength of steel are adopted. These doors and windows are designed with a multi-chamber structure, which can better block noise and alternation of heat and cold. The K value of the basic product is about 1.4, and the sound insulation is 40-45 points. At the same time, such products use aluminum as the outer coat, which prevents direct sunlight and eliminates the problem of photoaging from another level. At the same time, the hot-melt peritoneal film technology is used on the indoor side, and the substrate is wrapped again for double protection. , so fundamentally solve our so-called plastic steel aging problem. At the same time, the frame connection of such products has also realized the bare connection technology. The internal steel lining is connected in a 360-degree closed manner to form an overall structure. The interior is made of 2.0 square steel, and the construction site passes through the steel lining through expansion bolts. It is fixed to the wall, which greatly increases the wind pressure resistance and safety performance of doors and windows. Such aluminum-coated plastic doors and windows are slowly being recognized and sold by people in the door and window industry in China.
2. Broken bridge aluminum doors and windows, these products are upgraded and transformed on the basis of previous aluminum alloy doors and windows. By using nylon strips or UPVC insulation strips as the middle insulation bridge connection, the convection of heat is blocked to achieve the effect of heat insulation. It is generally represented by the wide-type broken bridge window, which adopts 108, 120 and other profile structures, and generally adopts a 3-cavity structure design. The surface treatment process is mainly spraying or fluorocarbon spraying, and the process is relatively simple. The products represented by the broken bridge of the northern system are basically 70, 75, and 85 profile structures. By widening and enlarging the intermediate nylon and UPVC profiles, and at the same time, the thermal insulation profiles are designed with multiple cavities to achieve better thermal insulation effect. Generally, the K value of such products is about 2.0, and the sound insulation is about 30-35 points. In order to achieve better thermal insulation effect and reduce the K value, some manufacturers will fill the cavity with foaming materials, but the cost will be higher. increased accordingly. This type of product is currently the most popular product on the market, but the products are mixed and uneven. It is recommended that you do not be deceived.
3. Aluminum-clad wood products, which are designed using the weather resistance of aluminum and the heat insulation and thermal insulation properties of wood (similar to "roujiamo" with less meat in the first place, aluminum-clad wood and aluminum in the first place). This type of product is evolved from the previous solid wood window. These products are basically 68, 86, and 90 profiles, and the width of profiles from different manufacturers is slightly different. Such products are mainly in the north and less in the south, because most of these products are mainly pine, and some expensive woods will use some oak, teak, etc. Due to the characteristics of the wood itself, there is a lot of rain in the south, which leads to the maintenance of the wood. Maintenance costs will be higher. However, aluminum-clad wood products have won the favor of more groups due to their superior performance. The thermal insulation effect of such products is quite good, and the K value is around 1.6. Such doors and windows are generally expensive, and the really better aluminum-clad wood products are even more expensive. It is recommended that you make more comparisons when purchasing such products.
We have basically analyzed the three types of products. From the evolution of these three types of products, we can find a common point. The development of doors and windows is seeking a higher performance parameter (K value), which also returns When it comes to the essence of a door and window, the door and window is a strong light-transmitting side, and it is a very important part of the outer structure of our house. It should not only play the role of lighting and ventilation, but also have the thermal insulation of the wall. In 2020, In 2021 and 2022, the requirements and testing of engineering doors and windows will become more and more strict, and the k-value requirements of doors and windows will also become higher and higher. At present, as the best energy-saving passive house building, it is also more and more favored by people. The design of the structure of the house itself should also be matched with better energy-saving doors and windows (passive doors and windows require K≤0.8) to achieve the effect of not actively relying on energy and through the structure of the house itself to achieve the effect of being warm in winter and cool in summer. Therefore, as a door and window, it is particularly important, after all, it is the weakest link of the house.
The three types of doors and windows have their own advantages. I hope today’s sharing can bring you more inspiration for choosing doors and windows. Doors and windows are used for a lifetime and focus on performance.
