The purpose of air duct panels in heating, ventilation and air conditioning systems is to remove and deliver air. Without a good duct system, it would be difficult to achieve thermal comfort as well as ensuring that you have good quality air for your indoor environment. Over the years, several designs have been used to craft ductwork with the aim of improving thermal efficiency and the quality of air which goes through them. Below are the most recently developed options which as you will note, are categorized using production material as the major factor.

Phenolic foam (pre-insulated)

Conventionally, air ductwork was made using a sheet of metal which was first installed and then lagged with insulation afterwards. Today, manufacturers prefer fabricating the galvanized steel duct with its duct wrap so that the panel will be installed in a single step. Phenolic foam ducts which are pre-insulated are manufactured using the above described technique too albeit phenolic foam is used in the place of galvanized steel and aluminum. Preference for phenolic foam is for obvious reasons which would be affordability and functional advantage in that phenolic foam is lighter than either aluminum or galvanized steel.

Fiberglass ducts

Fiberglass ductwork is regarded as the most advanced option due to their superior properties. For one, they come with built-in thermal insulation and additionally, such a panel's interior surface absorbs sound implying that operational noise from the FIVAC will be trapped for very quiet interiors. This is by far the best option but not the most popular noting that its convenience and superiority makes it the most costly of all.

Polyurethane foam ducts

Polyurethane foam ductwork is similar to phenolic ducts only that polyurethane foam is used in the place of phenolic foam. Within this type, there are various types of polyurethane foam duct including the water formulated panel whose foaming process results from the use of water and carbon dioxide instead of conventionally used gasses like CFC and F1FC. Note that both polyurethane and phenolic panels are designed to have factory lagged aluminum facings on both sides. The thickness of the aluminum foil depends on the application for which the air ductwork is intended. It could vary from 25 micrometers if the panel is intended for indoor use up to 200 micrometers for outdoor applications.

Due to the lightweight property and affordable prices, polyurethane and phenolic foam air duct panels have become the most popular option for both commercial and residential home applications. Fabric duct system
