Aluminium are the most common materials for sheet metal ducts since they areleast likely to har-
bour dangerous moulds or growths because they have non-porous surfaces. Ducts are conduits or
passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The
needed airflows includesupply air, return air and exhaust air. Ducts commonly also deliver ventilation
air as part of the supply air. 22G aluminium ducting provide an ideal ducting solution and long life.
HVAC ductwork and systems require external thermal insulation to keep air temperature and sys-
tems running as designed. Investing in a fully adapted external insulation solution also has numerous
benefits for project owners (reduced energy consumption), installers (lightweight and easy to
handle) and occupants (improved comfort). Reduce the amount of heat (or cold) energy needed to
maintain the air temperature as designed, while also preventing the formation of condensation. Sig-
nificantly reduce the amount of noise transmitted through the ductwork and pipework in the HVAC
system. To protect building users and occupants with our non-combustible insulation materials, with
no contribution of toxic smoke or flaming droplets. 13 & 19mm thick class ‘o’ nitrile rubber with
aluminium foil is ideally preferred.
