Panel advantages
☆It has excellent thermal insulation.The thermal insulation coefficient of polyurethane sandwich panels is 0.022 W/m.K.
☆If coating type is selected properly,according to local weather,the PIR panels can have excellent protection against weather conditions.
☆The joint of cold room panels is with excellent tightness,because it's seamless with polyurethane sealing together.
☆The cold room panels can be installed quickly;
☆Wide range of panel colors for choices,the PUR panels can be used widely for various profile types of claddings.
