Product Description

Advantages of DG polyurethane sandwich board

1, Energy-saving and thermal insulation:
Hole-closing rate of core material is ≥ 97% and thermal insulation performance is excellent.

2, Flame retardant and fireproof:
The product has passed the inspection of China National Center for Quality Supervision and Test of Fixed Fire-fighting Systems and Fire-resisting Building Components and the combustion grade reaches corresponding standard of GB8624-2006.

3, Air tightness and sound insulation:
Good sound absorption, with the function of reduction for the sound caused by rainwater and hailstone

4, Environment-friendly:
Without containing formaldehyde, free from invasion by microorganism, recycling

5, Beautiful and economic:
Surface types are many and colors are rich; Reducing material wastage and saving construction time and cost.

6, Fast in construction:
Polyurethane board is to be produced under height controlled and temperature constant conditions of the plant, and the quality is stable.

7, Rapid in construction:
The application has exceeded 35 years.

Board type:

System composition:
Upper profiled sheet, polyurethane thermal insulation material, and lower profiled sheet

Connection way:
Polyurethane roof board is to be connected onto the purline with tapping screws and to be connected with the other board through lapping (the upper laps with the lower).

Product features:
DG polyurethane roof board uses concealed nail for connection and boards are lapped together tightly.
Unique waterproof groove design, effectively preventing rainwater leakage and avoiding cold bridge phenomenon
40mm corrugation height, greatly improving bearing capacity of roof board and also effectively lowering customer construction cost while ensuring building thermal insulation effect; Minimum roof slope can reach 3%

Scope of application:
No-bearing roof enclosure of various industrial workshops, civil buildings, public buildings and steel structure buildings
