Don\’t choose the window again! 2025 Alcohol System Window Selection and Pit Avoidance Guide

In 2025, the decoration trends continue to change, and the windows of aluminum alloy systems have become the best place for many home decorations with their excellent performance. However, the quality of the windows of aluminum alloy system on the market is quite different. If you are not careful, you may fall into various \”pits\”. Today, I will present a super practical guide to purchasing pit avoidance for your master, so that you can easily choose a high-quality aluminum alloy system window.

As the \”bone\” of a door window, the quality of the profile directly relates to the durability and stability of the door window. When choosing, you must divide ordinary aluminum alloy and bridge aluminum alloy. The bridge aluminum alloy adopts heat-separation technology to open the aluminum alloy profile, greatly reducing the heat-separation. Whether it is a hot summer or a cold winter, it can effectively maintain the indoor temperature and greatly reduce the energy consumption of air conditioning and heating. Currently, the mainstream heat insulation material on the market is PA66 Nilong, with the number GB/T 23615.1-2009. This material has good heat insulation, sound insulation and weather resistance.

Especially when living in high-level areas or areas with higher requirements for door and window strength, you must strictly control the thickness of the profile, otherwise the door and window will easily deform and shake in the future, which will be extremely jeopardized.

Profile wall thickness

Glass is the \”eye\” of the door and window, not only affects the lighting, but also plays an important role in sound insulation, heat insulation, etc. Currently, common glass types on the market include steel glass, LOW-E glass, and clamped glass. You must choose steel glass with 3C certification marks first. This glass will become small particles after it is broken, which can effectively avoid serious damage to the human body. Generally speaking, the thickness of the glass original sheet must reach at least 5mm. If the budget is sufficient, three-layer hollow glass is highly recommended, which can better isolate external noise and heat, creating a peaceful and comfortable living environment for you. If you pursue heat insulation and temperature protection, it may be a good ideaConsider LOW-E glass, which can effectively block UV and red external lines and reduce indoor heat transmission. Clamping glass has excellent safety and will not cause damage even if it is broken. It is suitable for places with high safety requirements. When installing, you must carefully check whether the glass is flat and firm. The outer surface of the double-layer hollow glass must be cleaned. There must be no dust or water vapor in the trunk, otherwise it will seriously affect the visual effect and heat and sound insulation performance.

Severe hardware accessories are small, they play an important role in the opening and closing process of doors and windows, directly affecting the use experience and sealing of doors and windows. Because the doors need to be opened and closed frequently, poor quality hardware accessories can easily get damaged. For accessories such as screws, joints, handles, and sliders, it is recommended to choose products from well-known brands, which are more guaranteed in quality and after-sales. When purchasing, carefully observe the appearance of hardware accessories, whether it is exquisite, whether it is fine, whether it is smooth when it is opened, and whether it has a feeling of caulking or rawness. These details can reflect the quality of hardware accessories.

Sealing is also an important standard for measuring the quality of windows of aluminum alloy systems. Sealing strips are the key to achieving good sealing. Currently, the mainstream sealing strips on the market are EPDM, which has excellent aging resistance, high and low temperature resistance and chemical corrosion resistance. The sealing strip must be flat when it contacts the glass and the notches, and there must be no curling or groove removal. When the door and window are half closed, there should be no clear gap between the fan and the frame, and the sealing strips on the sealing surface should be in a compressive state. Only in this way can the penetration of rainwater, dust and cold air be effectively blocked. In addition, during the installation process of doors and windows, the sealing treatment between doors and walls cannot be ignored. It is recommended to use silicone sealing glue, which has good adhesion, weather resistance and water resistance, and can effectively avoid the problems of wind and water leakage.

Lastly, when choosing an aluminum alloy system window, the selection of materials is important, but what is more important is the equipment and technical level of the production factory. In order to reduce costs, some bad businesses not only cut off materials in key areas such as profiles, glass, hardware, etc., and use inferior products as good ones, but their production equipment and technology are often backward, resulting in poor product quality. This makes it seem like a big advantage, but in fact, the future is insignificant. The repair cost in the later stage will not only be high, but may also affect the safety and comfort of the living room. It is recommended that Dali choose brand products with good market reputation and complete after-sales system as much as possible. These brands have advanced production equipment and mature technical craftsmanship, and are more precise in profile quality control, production process specifications, and quality standard review, which can provide you with better products and services.

Master these key points for purchasing. I believe that when you choose the door window of the aluminum alloy system in 2025, you will definitely be able to avoid various \”pits\” and choose beautiful and practical doors for your own products, and enjoy a high-quality living life.
