PUF Insulated Panels

Frick makes PUF insulated panels that will be clad on both sides with 0.5 mm thick (TCT) pre-coated GI sheet in an off-white colour (RAL 9002), having a minimum 240 MPa steel grade confirming to IS 12436:1995 and a zinc coating of at least 120 gsm as per IS 277:1992, 5-7 microns of epoxy primer on both sides of the sheet, and a polyester top coat of 15 to 18 microns. The external surface of the sheet will be pre-painted with a minimum 25-micron-thick regular modified polyester coating. Our PPGI sheets have a plastic protective film of at least 25 microns to make them scratch-proof. The panels will be provided with cam locks and vertically joined together by a tongue-and-groove jointing system for leak-proof joints. The thermal conductivity of PUF will be (0.023 + 5%) w/m°k. The blowing agent used in the process is R-141b, which is CFC-free. The PU foam will be self-extinguishing and fire-retardant, with a PUF density of 42 kg/cu m (+ 2 kg/m3).
