Welcome to inquire! Contact: Zhu Yong. Rigid polyurethane board with low thermal conductivity, good thermal performance. When the density rigid polyurethane for 35 ~ 40kg / m3 foam insulation box when the fifth production, thermal conductivity is only 0.018g ~ 0.023w / (m.k) V foam insulation box, equivalent to about half of the fifth EPS foam insulation box processing, the insulation material is present all the lowest thermal conductivity. Because polyurethane sheet has excellent insulation properties, to achieve the same insulation under the requirements of the building can reduce the thickness of the external structure, thereby increasing the indoor area.
