Modern commercial buildings are designed to be air-tight and can utilise a system of ducted warm air to maintain comfortable occupancy temperatures. However, un-insulated ductwork is subject to inevitable temperature losses which represent over 50% of the system energy requirements. To help eliminate these losses, Armaflex purpose engineered ductwork insulation can provide both thermal and acoustic properties. Information on these products is provided on a dedicated micro-site, forming part of the Armacell website (www.armacell.com/uk).
