Sandwich board, composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the polymer core insulation composition, easy to install, light and efficient. Filling system is also used to close the molecular structure, Sandwich Panel you can put an end to the condensation of water vapor. Sandwich board is a common product in the current building materials, not only good flame retardant and environmentally friendly and efficient.
The current classification of sandwich panels are: polystyrene sandwich board that is EPS sandwich panels (currently on the market, the most widely used varieties); extruded polystyrene sandwich panels that XPS sandwich panels; rigid polyurethane sandwich panels that PU sandwich panels; Sandwich Panel Polyester sandwich board that is PIR sandwich board; phenolic sandwich board that is PF sandwich board; rock wool sandwich board that is sand sandwich panels.
What are the characteristics of sandwich panels?
1, the quality of light: sandwich panels per square meter weight less than 24kg, can fully reduce the structural cost.
2, the installation of fast: sandwich board light weight, plug, Sandwich Panel install and can cut the characteristics of arbitrary, to determine the ease of installation, can improve efficiency and save time.
3, fire: sandwich board surface material and insulation materials for non-flammable or flame retardant materials, to meet the fire safety requirements.
4, fire: the special coating of the sandwich board to protect the new 10-15 years, after every ten years spraying anti-corrosion coating, sheet life of 35 years or more
5, beautiful: sandwich plate clear lines up to dozens of colors, with any style of the building needs
6, thermal insulation: commonly used insulation materials are rock wool, Sandwich Panel glass fiber cotton, polystyrene, polyurethane, thermal conductivity is low, with a good thermal insulation effect.
7, environmental protection noise: sandwich board sound intensity up to 40-50 dB, Sandwich Panel is a very effective sound insulation material.
8, plasticity: sandwich panels can be arbitrarily cut, enough to meet the needs of special design.
9, high strength: the use of high-strength steel plate as the substrate, tensile strength of 5600 (kg / cm2), coupled with the most advanced design and roll forming, with excellent structural characteristics.
