1 sound insulation: the average sound insulation shall not be less than 35dB;
2 high absorption coefficient: the average sound absorption coefficient should not be less than 0.84;
3 residential sound barrier durability: the product should have water resistance, heat resistance, UV resistance, not due to changes in the temperature of the rain caused by reduced performance or quality anomalies. The products are made of aluminum alloy coil, galvanized coil, glass wool and H steel column, and the corrosion resistance of galvanized steel is more than 15 years.
4 beautiful: you can choose a variety of colors and combinations of shapes, with the surrounding environment, the formation of beautiful scenery line.
5 economy: assembly construction, improve work efficiency, shorten the construction time, can save construction costs and labor costs.
6 convenience: parallel with other products, easy maintenance, easy to update.
7 sound barrier. Light: sound barrier products with light weight characteristics, can reduce the foundation, the foundation load bearing capacity, can reduce the cost of the structure.
8 fire prevention: the use of ultra-fine glass wool, because of its high melting point, non combustible, fully meet the requirements of environmental protection and fire safety requirements.
9 high strength: according to different climatic conditions in different regions of China, the wind load is fully considered in structural design. Increase strength by pressing grooves on the production line.
10 waterproof, dustproof: when the material is designed to fully consider waterproof, dustproof, dust or rain in the environment, the sound absorption performance is not affected, the structure has been set up dust drainage measures to avoid internal water.
