Polyurethane board is produced by integrating nonwoven fabric and aluminum foil on both sides of rigid polyurethane board, and there are two types of PUR Board made of general polyurethane and PIR Board of which stability feature against fire is enhanced.
The polyurethane has the lowest thermal conductivity (0.020w/m·k) among the building insulation materials, and this is the best insulation performance among insulation materials which are currently commercialized. The PIR Board with flame retardant performance meets both the energy saving and fire safety of buildings by solving the problem of combustibility which is the problem of the existing organic insulation.

PIR Foam, as an abbreviation of polyisocyanurate, is an excellent insulation that removes the characteristics of high-temperature which damage and deform the characteristics of the insulation, and reduces the ductility.
PUR, as an abbreviation of polyurethane, is a high molecular substance that is a combination state of a large amount of urethane (-NHCOO) generated by the combination of isocyanate and polyol. Panel Tech corporation’s board maintains anti-condensation effect as it is due to the excellent thermal insulation, and there is almost no shrinkage and expansion at low temperature, so, it demonstrates excellent performance in freezing and low temperature warehouse and so forth.
