What are the differences between ventilation duct and insulation duct

The thermal insulation air duct plate is mainly made of double-sided composite protective layer of thermal insulation layer, and the thermal insulation layer is mainly divided into two categories: foam and glass wool.

Common air duct panels are aluminum foil composite phenolic foam board, aluminum foil composite polyurethane foam board, aluminum foil composite extruded polystyrene foam board, etc. This kind of air duct is ideal in terms of performance, small thermal conductivity, light weight, easy construction, clean, etc., and has been used in many public civil buildings, including high-rise buildings.

The basic functions of the ventilation pipe mainly include:

The conveying air does not produce noise, or has the function of noise reduction to ensure that the air in the air duct will not leak outside or the air outside the air duct will not intrude inside the air duct under the allowed pressure conditions.

Conveying hot and cold air to various places in the building to ensure that the air temperature, relative humidity, transmission speed and cleanliness and other technical performance unchanged At present, there are many types of air ducts in the market application, in addition to the traditional iron duct and glass fiber reinforced plastic duct, a new type of composite thermal insulation duct processing directly made with insulation board began to cause extensive concern in the building HVAC industry.
