Characteristics:

• Energy-saving, lightweight, and environmental protection
• Polyphenyl granule in Vanjoin board has good heat-insulation effect and heat lost ratio is far below the other brick wall building
• Energy-saving effects of the building is greatly improved
• Raw materials do not include harmful substances
• Environmental products, it is highly recommended by the government
• Capacity: 650kg/m³, just one sixth of the brick building
• Comparison of inner wall panel 75 and 120mm it will increase 12m practical area, for 100m² house, it will increase 4.16m²
• Waterproof and damp resistant
• With fireproof feature
