anxious! Will the polyurethane sandwich panels of various parameters, plant design!
Polyurethane is a two-component AB material (isocyanate and combined polyether) mixed foam, is the thermal insulation material in the lowest thermal conductivity of 0.017 ~ 0.024 (thermal conductivity of the lower the better insulation). Polyurethane sandwich panels used in the filling process of polyurethane, pre-made pre-insulation board directly installed on-site use. If your plant area is relatively large, it is recommended that you only use the whole color plate, and then use the field of polyurethane spray foam process, this process than the infusion process is the advantage of spraying seamless, better insulation. The cost is still lower than the infusion process.
