PolyisocyanurateRoof Insulated Panel
PIR is typically produced as a foam and used as rigid thermal
insulation.Its thermal conductivity has a typical value of 0.16
BTU*in/hr*ft*°F (0.023 W/(m·K)) depending on the perimeter:area
ratio.PIR foam panels laminated with pure embossed aluminium foil
are used for fabrication of pre-insulated duct that is used for
heating, ventilation and air conditioning systems.
