Doors and windows, as an important part of building space, not only bear the functions of lighting, ventilation, and safety protection, but their service life also directly affects the long-term use cost and experience of homes or buildings. The core of determining the durability of doors and windows is the choice of their materials. From metal to wood, from traditional materials to new composite materials, different materials have their own advantages and disadvantages. In-depth analysis of durable door and window materials can provide consumers and construction practitioners with a scientific basis for material selection, and effectively extend the service life of doors and windows. ​

Metal material: a representative of sturdiness and durability ​

Aluminum alloy material ​

Aluminum alloy is one of the most widely used metal materials in modern doors and windows. It is based on aluminum, with alloy elements such as copper, magnesium, and silicon added, and is made through processes such as smelting and extrusion. Aluminum alloy has low density, light weight, easy processing and installation, and high strength. It can withstand large loads without deformation. Its surface can be treated by anodizing, powder coating, electrophoretic painting and other processes to form a solid oxide film or coating, which effectively resists the erosion of ultraviolet rays, rain, acid and alkali substances, and is not easy to rust and fade. Whether in the hot and rainy south or the cold and dry north, aluminum alloy doors and windows can maintain good use status, with a normal service life of 20-30 years, and are a common choice for residential and commercial buildings. ​

Broken bridge aluminum material

Broken bridge aluminum material is an "upgraded version" of aluminum alloy. It embeds a heat insulation strip in the middle of the aluminum alloy profile, breaks the metal profile to form a "broken bridge" structure, which not only retains the advantages of high strength and corrosion resistance of aluminum alloy, but also significantly improves the thermal insulation performance of doors and windows. The heat insulation strip is usually made of PA66GF25 nylon, which has an extremely low thermal conductivity and can effectively block heat conduction. In addition, the broken bridge aluminum doors and windows are more sophisticated in sealing structure and hardware accessories. The use of multiple sealing strips and high-quality hardware makes it waterproof, dustproof and windproof. It is not easy to deform and seal failure after long-term use. The service life can reach more than 30 years. It is often used in mid-to-high-end construction projects with high quality and performance requirements.​

Steel​

Steel has extremely high strength and hardness, and can withstand strong impact and load. Steel doors and windows are the first choice in places with extremely high security requirements, such as banks, warehouses, industrial plants, etc. Steel has greatly improved its anti-rust ability after being treated by hot-dip galvanizing, spraying anti-corrosion paint and other processes. However, steel has high density and weight, is difficult to process and install, and has relatively high cost, so it is rarely used in home decoration. But with its strong and durable characteristics, the service life of steel doors and windows can be as long as 30-50 years. ​

Wood: A fusion of nature and durability​

High-quality wood such as mahogany, walnut, oak, etc. has a hard texture, beautiful texture, good toughness and stability. After drying, anti-corrosion treatment and surface coating, the wood's resistance to deformation and corrosion is significantly enhanced. For example, wood treated with vacuum pressure anti-corrosion can effectively prevent the invasion of fungi and termites; the surface is painted with environmentally friendly wood paint to form a protective film to isolate moisture and ultraviolet rays. Although wood may be slightly deformed due to changes in environmental humidity during long-term use, through careful care and regular maintenance, the service life of solid wood doors and windows can reach 20-30 years, and over time, it will form a unique texture and charm, adding a natural atmosphere to the space. ​

New composite materials: innovative and durable choice ​

Aluminum-clad wood composite materials ​

Aluminum-clad wood doors and windows combine wood with aluminum alloy. Natural wood is used on the inside to show the warm texture and decorativeness of wood, and aluminum alloy is wrapped on the outside to enhance the weather resistance and impact resistance of doors and windows. This material not only retains the beauty of solid wood doors and windows, but also solves the problem that wood is easily affected by the external environment. The outside of the aluminum alloy can be treated with a variety of colors and surface treatments to adapt to different architectural styles. At the same time, the wood part can be painted according to preference to achieve a perfect fusion of beauty and durability, and the service life can reach 25-35 years. ​

Plastic steel material ​

Plastic steel doors and windows are made of polyvinyl chloride resin as the main raw material, adding a certain proportion of stabilizers, colorants, fillers, etc., and are made by extrusion molding. It has good heat insulation and sound insulation properties, and the price is relatively affordable. At the same time, plastic steel is not easy to rust, corrosion-resistant, and has strong weather resistance. It can also be used stably in humid, acidic and alkaline environments. However, as the service life increases, plastic steel doors and windows may have problems such as aging and discoloration. However, by selecting high-quality products and using and maintaining them correctly, their service life can reach 15-20 years, which is an ideal choice for economical construction projects. ​

The choice of door and window material is a key factor in determining its service life. Different materials have their own advantages and are suitable for different building scenes and needs. When purchasing doors and windows, consumers and practitioners should comprehensively consider factors such as the use environment, budget cost, and performance requirements, choose suitable materials, and pay attention to the processing technology and installation quality of doors and windows, and cooperate with regular maintenance, so as to give full play to the durability of door and window materials, extend their service life, and achieve long-term practical value and economic benefits.
