When the bulk density of rigid polyurethane is35～40kg/m3When the thermal conductivity is only0.018g~0.023w/（m2．k）, approximately equivalent toEPSHalf of it is the thermal conductivity of all insulation materials currently available.
Hard polyurethane has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is90%The above belongs to hydrophobic materials, which will not increase thermal conductivity due to moisture absorption, and the wall will not leak water.
Hard polyurethane is fire-resistant, flame-retardant, and heat-resistant. Polyurethane, after adding flame retardants, is a flame-retardant self extinguishing material, and its softening point can reach250If the temperature is higher than Celsius, it will decompose only at a higher temperature. In addition, the polyurethane will form ash on its foam surface when burning, which helps to isolate the foam below. Can effectively prevent the spread of fire. Moreover, polyurethane does not produce harmful gases at high temperatures.
Due to the excellent thermal insulation performance of polyurethane panels, they can reduce the thickness of building envelope structures and increase indoor usable area while meeting the same insulation requirements.

Strong deformation resistance, not easy to crack, stable and safe finish.
Polyurethane materials have a stable porosity structure, basically a closed cell structure, which not only has excellent insulation performance, but also has good frost resistance and sound absorption. The average lifespan of the rigid polyurethane insulation structure can reach under normal use and maintenance conditions30Years or more. It can achieve normal use conditions during the service life of the structure, without being damaged by dry, humid, or electrochemical corrosion, as well as external factors such as insect, fungal, or algal growth or rodent damage.
Low overall cost-effectiveness. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by the substantial reduction of heating and cooling costs.
