light steel villa is mainly composed of fireproof board, light steel keel, insulation cotton, particleboard, breathing paper, insulation board (XPS extruded board), paint layer, exterior layer.

Among them, the key to the insulation is the insulation cotton and the insulation board.

one, insulation cotton

1. Rock wool

rock wool is made of natural rocks and minerals as raw materials, after high temperature fiber after adding the right amount of binder. It has good heat insulation, fire resistance, sound insulation.

2. Glass fiber cotton

glass uses a centrifugal blowing process for fiberization, spraying a filamentous material made of thermosetting resin, and heat curing to make a product. Glass wool belongs to a category of glass fiber and is a kind of man-made inorganic fiber. Glass wool is the molten glass fiber, the formation of cotton-like material, chemical composition belongs to the glass class, is a kind of inorganic fiber. With good molding, small volume density, thermal conductivity, thermal insulation, good sound absorption performance, corrosion resistance, chemical stability, usually glass wool roll felt.

two, insulation board

1.XPS Extruded Board

Extruded polystyrene plastic insulation board uses polystyrene resin as raw material and other auxiliary materials, and simultaneously injects catalyst through heating and mixing, and then extrude the formed rigid foam plastic board, which has perfect closed-cell honeycomb structure, so that XPS board has extremely low water absorption, low thermal conductivity, high pressure resistance and strong aging resistance.

2.EPS molded plate

The polystyrene foam board with closed cell structure, which is formed by heating and pre-foaming the expandable polystyrene beads in the mold, has heat preservation, waterproof and anti-aging, and its performance is slightly worse than that of XPS board.
