Armacell UK says distribution and
continuous re-circulation 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
gases such as CO2, as well as harmful
VOCs, industrial fibres, acidic
particles and general dust, mould
spores and bacteria – which can
contribute towards the impact of
‘sick building syndrome’.

Armaflex purpose-engineered
duct system products provide an
easy-to-clean, efficient insulation
with zero ratings for ozone depletion
and global warming potential. They
combine thermal and acoustic
properties to help maintain safe and
comfortable environments within
workplaces or public areas.

Products are free of dust and fibres,
formaldehyde and other dangerous
gases. A closed-cell structure with an
in-built water vapour barrier is said
to eliminate 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.
