Product List

ALPHA-PIR PANELS

ALPHA-PIR panels consist of a formaldehyde free, fiber free, high performance rigid thermoset Polyisocyanurate foam core faced on both sides with an extremely durable, protective, low vapor permeability aluminium foil. The foam core is produced using a CFC / HCFC free blowing agent having a zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) lower than 5. The aluminium foil is bonded to the foam core by heat reaction during the manufacturing process without using additional adhesives. The aluminium foil is lacquered with a factory applied corrosion and UV resistant polymer coating.
