Sandwich Panel

Color steel sandwich panel
The composition of the color steel sandwich panel includes colored steel tiles on both sides and an insulation layer in the middle. There are four types, foam sandwich panel, glass wool sandwich panel, rock wool sandwich panel, and polyurethane sandwich panel.

　　Foam sandwich panel

parameters
Foam sandwich panel is an economical building material, which has the advantages of being lightweight, having good thermal insulation performance, and low water absorption, and can be used in low-temperature environments. It is very convenient to install and replace and is widely used as wall panels and roof panels.

performance description
Energy-saving and thermal insulation: the thermal insulation performance is superior, and the thermal insulation effect of the same thickness is twice that of EPS boards.
Flame retardant and fireproof: The product has passed the "National Fixed Fire Extinguishing System and Fire-resistant Component Quality Supervision Center Inspection", and the combustion level has reached the GB8624 B2 standard.
Airtight sound insulation: good sound absorption, and can reduce the sound caused by the impact of rain, hail, etc.
Waterproof and antirust: large span, fast drainage, good waterproof effect; hidden screws, not easy to rust, prolonging the service life of the board.
Beautiful and economical: beautiful appearance and rich colors; reduce material loss, save construction time and project costs.
Fast construction: Polyurethane panels are produced in a highly controlled and constant temperature environment in the factory, with stable quality; fast construction, and have been used for more than 35 years.
