How to choose the material of doors and windows?

Doors and windows are an important part of home space. In addition to ventilation, doors and windows can also play a role in decoration, privacy protection, and property safety, so we must not take it lightly when purchasing doors and windows. However, there are many types and styles of doors and windows on the market, so how to choose the most suitable doors and windows?

Aluminum wood doors and windows

Aluminum-wood doors and windows are actually combined doors and windows of aluminum and wood, and a layer of broken bridge aluminum alloy is wrapped outside the solid wood material, so it has the advantages of solid wood doors and windows and broken bridge aluminum doors and windows at the same time, which is both beautiful and practical. The airtightness of aluminum-wood doors and windows is better than that of broken bridge aluminum of ordinary aluminum alloy profiles, and there will be no water mist on the glass and window sills.

Aluminum-wood doors and windows are made of solid wood, which can better absorb the vibration of sound waves than aluminum alloy or plastic steel. Tests have shown that top-quality aluminum-wood windows can block 35 decibels of outdoor noise.

However, aluminum-wood doors and windows have the disadvantage of being easy to deform—wood is easy to deform, and it is easy to cause inconvenient opening and closing of doors and windows when thermal expansion and contraction occur, and it is easy to be mothed and cracked, and there is even a certain fire hazard. Therefore, from the perspective of safety and durability, It is not recommended to use aluminum wood doors and windows.

Steel windows and doors

Steel doors and windows can be divided into ordinary carbon steel doors and windows, color plate doors and windows, stainless steel doors and windows, high-grade heat-insulating steel doors and windows, etc. according to the material. Steel doors and windows are generally durable, high-strength, and have the characteristics of fire resistance and moisture resistance. However, in order to ensure the strength, the light transmittance of steel doors and windows is generally low, and the cost performance is not high. In addition, steel doors and windows have a large thermal conductivity, do not have strong heat preservation and sealing, and have problems such as easy corrosion and high energy consumption in production.

Plastic doors and windows

Plastic doors and windows are doors and windows made of U-PVC plastic profiles. Among all kinds of building windows, plastic doors and windows have outstanding advantages in saving energy consumption in profile production, reusing recycled materials and using energy consumption, and have excellent performance-price ratio.

Plastic doors and windows have good heat insulation performance due to the multi-cavity structure of plastic profiles. Its heat transfer coefficient is extremely low, which is only 1/357 of steel and 1/1250 of aluminum. The relevant departments have obtained through experiments and comparisons: the indoor temperature of the room with plastic doors and windows is 4-5 ℃ higher in winter than that of wooden windows.

Plastic doors and windows have independent drainage chambers, and the accumulated water in both the frame and the fan can be effectively discharged. In addition, when the plastic doors and windows are installed, all the gaps are equipped with sealing strips and wool strips, so their airtightness is extremely high. The watertightness of plastic casement windows is higher than that of sliding windows. Generally, the watertightness of casement windows can reach level 5, and that of sliding windows can reach level 3 to level 4.

The profiles of plastic doors and windows can not only ensure the rigidity, strength, and wind pressure resistance of doors and windows, but also overcome the shortcomings of steel materials such as poor corrosion resistance, low thermal insulation performance (high thermal conductivity), and complicated manufacturing and installation. In addition, plastic doors and windows also have good corrosion resistance and sound insulation effects. In addition, the price is relatively cheap, and the materials are relatively environmentally friendly and low-carbon, and will not release excess indoor pollutant gases, so they are becoming more and more popular.

Fiberglass doors and windows

FRP is glass fiber reinforced material, which is a new type of composite material developed in the early 20th century abroad. It has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, and sound insulation. Fiberglass doors and windows use medium-alkali glass fiber roving and its fabric as reinforcing materials, and unsaturated resin as the matrix material. The two materials are compounded through a special process, and other mineral fillers are added, and then cured by heating. It is processed into various hollow profiles of different cross-sections.

The fasting abdominal cavity of FRP profiles does not use steel plates as the inner lining, does not require any single material for auxiliary reinforcement, and relies entirely on its own structural support. Because glass fiber and its fabric are used as reinforcing materials, there is no exposed hair after bonding with resin, and it is formed by mechanical pultrusion and thermosetting, so FRP doors and windows are resistant to bending, bending and deformation.

FRP is a high-quality composite material, so when exposed to various corrosive media such as acid, alkali, salt, oil, etc., FRP doors and windows will not rust. The life of ordinary PVC is 15 years, while the life of FRP is 50 years, which is basically the same as that of buildings. Therefore, the use of FRP doors and windows can reduce the trouble of replacing doors and windows and save money.

Aluminum alloy doors and windows

Aluminum alloy doors and windows are the first products to replace steel doors and windows. They are made of aluminum alloy extruded profiles as frames, stiles, and fan materials. Ordinary aluminum alloy sliding doors and windows use aluminum alloy as the main material, and their sealing and sound insulation effects are better than steel windows. , and are easier to process. Broken bridge aluminum alloy doors and windows are improved products based on ordinary aluminum alloy windows in order to improve the thermal insulation performance of windows.

The aluminum alloy profiles are divided into inner and outer parts by reinforced nylon spacers to block the heat conduction of aluminum, so the aluminum alloy doors and windows with broken bridges have excellent heat insulation, and completely solve the problems of ordinary aluminum alloy doors and windows with fast conduction and heat dissipation and poor heat preservation.

Aluminum alloy doors and windows, like doors and windows made of other materials, can be divided into several methods such as casement opening (inward opening, outward opening), sliding, hanging windows (top hanging, middle hanging, bottom hanging), and fixing. Aluminum alloy doors and windows with different opening and closing methods have their own advantages and disadvantages, and are suitable for different spaces.

Aluminum alloy doors and windows are one of the most popular door and window materials in the market at present. Because the production process of aluminum alloy doors and windows is relatively mature and the performance is good in all aspects, it has become the first choice of doors and windows for consumers.

Only by choosing the material of doors and windows, can the living comfort be doubled, and the subsequent use will not feel bad. Therefore, when purchasing doors and windows, you can comprehensively consider the advantages and disadvantages of the above door and window categories, and choose reliable brands and styles.
