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 magnesitic composite, PVC and so on have been developed as alternatives to the galvanized sheet metal used traditionally, pre-insulated duct is a fresh blood of duct systems. It is a sandwich panel that is made of a layer-silicate modified fireproof rigid 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.
