ZJT lightweight sandwich wall panels is a kind of energy saving light weight compound board, which can apply to interior wall, exterior wall, floor, roof and fence systems for house and buildings. It can replace construction materials like red brick, clay solid brick, air brick, color-coated steel sandwich wall board, gypsum block, wire spatial grid structure perlite board and perlite porous board.
1. The columns are inside the sandwich panel which makes it more beautiful and reality.
2. Compared with the earth building, the price is much lower and the installation time is much shorter.
3. Fire rate partition: 4 hours, reach to A level
4. Sound insulation: 38-46db
5. Thermal Conductivity: 0.221w/mk
6. Anti-earthquake: depend on the strength of steel structure (8 grade)
7. The using life is around 40-70 years.Environmental protection and economy.
8. Each worker can assemble 30~40 square meters every day, easy and fast installation.
9. Loading: 250-650square meters can be loaded in one 40 feet shipping container, it will depends on the size you need.
