10 Ductwork Heated and cooled air is distributed using ductwork including warm air return, supply, and exhaust systems. Rectangular ductwork is used for the main supply of heating and cooling systems, with circular ductwork and flexible hose sections used to branch off supply and return ducts to specific rooms. The large surface areas of ducted heating, ventilation and air-conditioning systems are subject to significant heat losses/gains and subsequent problems with condensation and mould growth. To address these risks and maintain the desired temperature of heated or cooled air, the rectangular and circular ductwork requires insulating. Ductwork can also be a source of unwanted noise and air pollutants that can contribute towards ‘sick building’ syndrome, causing problems such as viral infections, fatigue and a wider loss of productivity. The wrong choice of insulation can contribute to these problems in terms of condensation damage and pollutants in the form of dust, fibres and mould growth. ArmaFlex provides a dust and fibre free, and formaldehyde free duct insulation option. Pairing excellent thermal values with a closed cell structure, ArmaFlex can meet the energy efficiency targets for ductwork without any risk of impacting upon the indoor air quality or contributing towards sick building syndrome. ArmaFlex has added Microban® anti-bacterial protection to restrict mould growth, making it an obvious choice for improved air quality in schools, hospitals and offices. The fibre free materials are also easy to handle and work with, with no dust mask or gloves required. In addition flexible closed cell foams have excellent acoustic properties and can be used as a combined thermal and acoustic insulation solution. MARKET DESTINATION & APPLICATIONS HEATING, VENTILATION & AIR-CONDITIONING APPLICATIONS Air conditioning systems Air conditioning pipework for split, VRV and VRF systems is one of the most common applications for ArmaFlex tube insulation, offering high performance thermal properties and condensation control at reduced insulation thicknesses. ArmaFlex coils can be used at low line temperatures to -50˚C and in high humidity applications with product variants available to meet low smoke, non halogen and high process temperature requirements.
