The wall materials of light steel villas are diverse and mainly consist of a variety of materials with different functions. They are combined to meet various requirements of the building, such as structure, insulation, heat preservation, sound insulation, moisture prevention, and aesthetics. Here is a detailed introduction for you:

　　•Light steel keel: As the framework of the light steel villa wall, the light steel keel is synthesized from hot-dip galvanized steel strips through cold rolling technology. It features high strength, light weight, and corrosion resistance. It provides a stable support structure for the wall, ensuring the stability and load-bearing capacity of the wall. Its wall thickness usually ranges from 0.84 to 2 millimeters, and the spacing between wall columns is generally 400 •600 millimeters. This design can effectively bear and reliably transfer vertical loads.

　　•Insulation and heat insulation materials:

　　•Glass fiber wool: It is a commonly used insulation filling material for light steel villa walls. It is made by spinning glass into fine filaments and then weaving them into a cotton-like product. The internal fibers of glass fiber wool are intertwined, forming numerous small cavities filled with air. Due to the poor thermal conductivity of air, it has good insulation and heat insulation properties. At the same time, it can absorb noise generated in daily life and production, playing a certain role in sound insulation.

　　•Extruded polystyrene board (XPS): This is a closed-cell insulation material with extremely low thermal conductivity and excellent insulation performance. It is usually installed on the outside of the light steel keel to further enhance the insulation and heat insulation effect of the wall, effectively preventing the exchange of heat between indoors and outdoors.

　　•Structural panels:

　　•Oriented strand board (OSB): It is a commonly used board internationally. It has excellent environmental protection performance, is stable and does not deform easily. It has good overall uniformity and is convenient for processing. Its porous network structure gives it good sound absorption and noise reduction performance as well as insulation effects. It is generally fixed to the outside of the main structure of the light steel keel with self-tapping and self-drilling screws.

　　•Cement fiberboard: It is made from natural fiber materials and silicon substances. It has the characteristics of heat insulation, environmental protection, heat preservation, fire prevention, and is not prone to deformation. It also has a good decorative effect and can be used as an exterior wall panel.

　　•Calcium silicate board: It is made with inorganic mineral fibers or cellulose nanofibers and other loose short fibers as reinforcing materials and siliceous-calcareous materials as the main body through cementing materials. It not only has the functions of traditional gypsum boards but also has good fire resistance, moisture resistance, noise reduction, and a long service life. It is non-combustible during a fire and does not produce toxic smoke.

　　•Moisture-proof materials: Breathable paper is a moisture-proof material made of a special new type of polymer material. Its surface has extremely fine microporous structures. According to the principle of diffusion of concentration gradient difference, water vapor can freely pass through the micropores, but liquid water and water droplets cannot pass through due to surface tension. It tightly wraps the building perimeter, effectively preventing rainwater erosion and ensuring the service life of the building.

　　•Exterior wall decoration materials:

　　•Metal embossed panels: They come in a variety of styles and rich colors. They are beautiful and durable. At the same time, they also have certain insulation, heat insulation, and sound insulation properties. They can be directly installed on the outside of the wall to enhance the overall aesthetics of the villa.

　　•Cultured stone: It can create a natural and ancient architectural style, adding a sense of art and cultural atmosphere to the building, making the light steel villa more distinctive.

　　•PVC siding: It is relatively low in price and easy to install. It has good waterproof and moisture-proof properties, and its bright colors can meet different aesthetic needs.

　　The selection and combination of light steel villa wall materials fully consider various performance requirements of the building, providing a comfortable, safe, and beautiful living environment for residents.
