| Message: | Insulated Polyurethane sandwich roof panel or PU/PUR/PIR sandwich composite panel is a commonly used composite building material. The same as other types of structural insulated panels, it is also made up of two layers of structural board and one insulation core.
As a green, environmental-friendly, light and high-strength new building cladding material, in order to improve the thermal insulation effect of buildings and develop low-carbon economy, Norgit has actively responded to the national requirements on energy conservation and emission reduction and launched the PU/PUR/PIR sandwich composite panels with European quality and green environmental protection. url:http://www.norgitsteel.com |
