SIP/sandwich panel/EPS sandwich board for prefabricated buidling

It is a composite building material. It consists of a sandwich of two layers of structural board with an insulating foam in between. Panel skins are magnesium oxide boards. Insulation core can be Expanded Polystyrene(EPS), Extruded Polystyrene(XPS).

Performance:

1. Fire protection

2. Energy efficient

3. Water resistant

4. Mould resistant

5. Structural integrity

6. Environmentally Friendly

Specification

1. MGO board thickness: 3-20mm

2. EPS core thickness: 20-250mm

3. XPS core thickness: 50-120mm

4. Max width: 550mm

5. Max length: 3660mm

6. Connection can be Tongue & Groove, Camlock, two or four sides closed.

Other pattens can be designed by clients' requirements.
