Ductwork insulation for commercial buildings

Armaflex purpose-engineered ductwork insulation from Armacell can provide both thermal and acoustic properties within schools, hospitals, office complexes and large public buildings. According to the company, non-insulated ductwork is subject to inevitable temperature losses, which represent more than 50 per cent of the system energy requirements. Armaflex ductwork insulation has been specifically designed to help eliminate these losses.

The distribution and continuous recirculation of ducted filtered air is subject to the gradual accumulation of general pollutants, which can lead to breathing difficulties and symptoms of ill health for the building occupants. Typical contaminants can include natural gases such as carbon dioxide, in addition to harmful volatile organic chemicals (VOCs), industrial fibres, acidic particles and general dust, mould spores and bacteria, which can all contribute towards the impact of 'sick building syndrome' identified by illnesses and lost working days.

Armaflex duct system products, however, are purpose designed to provide an easy-to-clean and efficient insulation with zero ratings for ozone depletion and global-warming potential. They provide combined thermal and acoustic properties to help maintain safe and comfortable environments within workplaces or public areas. Armaflex products are clean, efficient and free of dust and fibres, formaldehyde and other dangerous gases. They also feature a closed-cell structure with a built-in water-vapour barrier.

This eliminates the possibility of fibre migration and moisture 'wicking', with the effect that Armaflex remains dry and mould is denied the moisture it needs to grow. The incorporation of Microban anti-microbial protection enhances the inherent resistance against mould growth to ensure that the quality of the ducted air is not compromised. Highly stable thermal values are maintained, as well as excellent acoustic properties to minimise noise transmission through the ductwork. Combining these attributes reduces overall weight and minimises both material requirements and costs for system installations.
