The lightweight composite energy-saving wall material is a non-load-bearing lightweight composite panel formed by once-fusing a thin fiber cement or calcium silicate board as the panel with a lightweight core material in the middle. This product boasts a solid, lightweight, thin structure, high strength, impact resistance, strong hanging power, heat insulation, soundproofing, fireproofing, waterproofing, easy cutting, and the ability to be cut to any slot without the need for leveling, dry work, and environmental benefits that other wall materials cannot match. This is aimed at achieving energy conservation. It will drive the construction industry from落后的湿法施工落后的wet construction methods to advanced dry construction, thereby realizing the industrialization of residential component production, modernization of technical equipment, and intensification of mass production.
Performance and Advantages of Lightweight Composite Energy-Saving Wall Materials
Environmental and fire-resistant
The lightweight, energy-saving wall materials made of polystyrene bead core boards use raw materials free of harmful substances to humans and are non-radioactive A-grade products, complying with the national standard GB/T 169-2005. These wall materials can withstand fire for over 4 hours at a high temperature of 1000 degrees Celsius, without emitting toxic gases, and their non-combustibility meets the national A-grade standard.
2. Overall Uniformity in Usage Area
Polystyrene bead sandwich panel energy-saving wall materials typically use 75mm wall panels, which is 85mm less than the thickness of a 120 brick wall. This means that using energy-saving lightweight wall panels, every 11.8mm extension can increase 1m of usable area. Due to its prefabricated construction and integrated three-in-one structure, the panels are connected to form a whole, offering impact resistance 1.5 times that of conventional masonry. Anchored using钢结构 methods, the wall has high strength and can serve as high-rise, large-span partition walls, with overall seismic performance multiples better than that of ordinary masonry walls. The polystyrene bead sandwich panel has a dense structure, good integrity, is non-deforming, and the wall surface is not prone to disintegration, offering excellent seismic performance.
Moisture and water-resistant, sound-insulating
Laboratory tests have proven that polystyrene particle core boards can be bonded with cement to form a watertight pool without any waterproof finish. The back of the wall remains dry without any traces, and no condensation occurs even in humid weather. The wallboard's surface panel is a professional waterproof board, featuring excellent waterproof and moisture-proof properties, suitable for damp areas such as kitchens, bathrooms, and basements. The cement fiber on the surface of the polystyrene particle core board and its internal materials all offer good soundproofing. A 90mm thick wallboard achieves a soundproofing rating of 43dB, meeting the soundproofing requirements for national residential buildings and significantly outperforming the soundproofing effectiveness of other brick masonry walls.
Insulation, thermal retention
The composite materials of the polystyrene particle sandwich panels are made from pure natural vermiculite, high-purity quartz powder, inorganic fibers, and plant fibers, which are cured through high-temperature, high-pressure steam treatment. This determines their excellent thermal insulation properties, enhancing your indoor environment. The polystyrene particle sandwich panels have the ability to automatically adjust the moisture content in the indoor air according to seasonal climate changes, maintaining a constant humidity level and achieving ecological regulation effects, in line with the trend of modern residential building development.
5. Staple and hangable
Insulation particle sandwich panels can be directly nailed or bolted for hanging heavy loads such as air conditioners, with a single-point hanging capacity of over 45kg. Moreover, the panel surface is smooth and dust-free, allowing for direct application of tiles, wallpaper, wooden cladding, and other decorative materials.
6. Lightweight and Economical
The weight of 75mm thick polystyrene particle sandwich panels is equivalent to just 1/7 of the weight of 120mm thick masonry, thereby reducing structural costs and increasing usable space. Construction is simple and convenient. The cost is significantly lower; for instance, extending a wall panel by 11.8 meters can add 1 square meter of usable space (the total cost for a wall extension of 11.8 meters long and 3 meters high or less does not exceed 4,000 yuan). The polystyrene particle sandwich panel walls can be termed "free walls." If the structural design of a building starts with the consideration of using lightweight wall panels, the structural material standards can be reduced, leading to a substantial decrease in the overall cost of the building.
