What material is rigid ductwork manufactured from?

• Aluminium

• Galvanised low carbon steel (LCS)

• Plastics

• Copper

What shapes can the sections of rigid ductwork be?

• Circular

• Triangular

• Square or rectangular

• Hexagonal

What is the shape of spiral wound ducting in cross-section?

• Square

• Rectangular

• Circular or flat oval

• Triangular

What materials can flexible ducting be manufactured from?

• Steel and copper

• Galvanised LCS and steel

• Aluminium or plastics

• Wood and fiberglass

Can flexible ducting be insulated?

• Only uninsulated

• Only insulated

• Can be either insulated or uninsulated

• Neither insulated nor uninsulated

What type of ductwork is useful for permanent heating, ventilation and air conditioning (HVAC) systems?

• Fibreboard ductwork

• Flue gas ducts

• Aluminium ductwork

• Rigid or metal ductwork

Why is fibreboard air duct mostly preferred for heating and cooling systems?

• Because it is lightweight

• Because it is made from polyethylene

• Because it is insulated

• Because it is easy to install
