Phenolic Foam Pre-insulated HVAC Duct  

phenolic foam pre-insulated hvac duct phenolic foam pre-insulated hvac duct is an excellent alternative to traditional galvanised iron(sheet metal) ductwork and is ideal for specifications where space or weight is restricted. compared with heavy galvanised sheet metal ducting that requires a second step to its installation process to both vapour seal and thermally insulate the ductwork, phenolic foam air duct offers a high performance, lightweight and robust ductwork system that requires only a single fix installation process. this not only makes it a high speed operation for projects on which time is critical but also provides the advantage of a considerable saving in space. the duct is fabricated from phenolic foam pre-insulated duct panels and accessories by a set of special tools. the panels consist of 20mm thickness phenolic foam insulation faced on both sides with 80micron thickness aluminum foil. we can also supply the full set of accessories and tools required to fabricate the duct. specification and technical data size 3900*1200*20mm foam density 50-60kg/m3 thickness of aluminum foil 80micron thermal conductivity(at 10°c mean temp) jis a1412(1994) 0.02w/m.k fire test classifications bs 476 class 0 astm e-84 class a ul94-1998 94v-0 closed cell content >90% water vapor transmission astm e96-05 0.05g/hr/sq m (at 23?, 50% r. h., 8.26mm thickness, 12 days) water absorption(% by volume) astm c209-98 0.25% compressive strength astm d1621-00 137.7psi tensile strength astm d1623-00 61.4psi dimension stability astm d 2121-99 0.3% maximum allowable wind velocity 12m/s continuous running maximum temperature 150? cfcs and hcfcs test headspace gc/ms not detected
