PRE INSULATED HVAC DUCT PANEL

Duct is a key part of central air-conditioning system. It plays a very important role in adjusting air condition in buildings. The air condition and appearance of buildings are related with duct quality. The material used for duct is constantly evolving in order to satisfy the demand for higher and higher quality, greater respect for the environment, and increased savings in energy. Many different materials and systems such as magnetite composite, PVC and so on have been developed as alternatives to the galvanized sheet metal used traditionally, but pre-insulated duct is a fresh blood of duct systems. It is a sandwich panel that is made with PIR (Polyisocyanurate) foam faced with aluminum foil. It seemed to be a trend to use AIR pre-insulated duct on world duct market instead of traditional duct systems. AIR pre-insulated duct has been steadily developed and spread around the world, as its application has been gradually extended to every type of air distribution system: industrial, civil and commercial.

For construction of air ducting in heating, ventilation and air-conditioning systems (HVAC), the Polyisocyanurate (PIR) foam panel with 45kg/m3 density, coated with 80/80µm thick embossed aluminum foil have two panel types:

Dernook PI-20: 20mm thickness - Indoor
Dernook PI-30: 30mm thickness - Outdoor


  • PA80E20: Dernook PUR Panel of 20mm Thickness with 80 micron embossed Aluminum foil on both sides
  • PA60E20: Dernook PUR Panel of 20mm Thickness with 60 micron embossed Aluminum foil on both sides
  • PA80SE20: Dernook PUR Panel of 20 mm thickness with one side 80 mic Aluminum smooth and another side 80 mic Aluminum embossed
  • PA200E30: Dernook Panel of 30 mm thickness with 200 mic Aluminum embossed on both sides
  • PA6200E30: Dernook Panel of 30 mm thickness with one side 60 mic Aluminum and the other side 200 mic Aluminum embossed.
