Application of Insulated Flexible Duct SM 131
SM#131 is a range of fully flexible ducting, which has been specially designed for
the HVAC Market. The SM#131 series has been developed to minimize the heat
gain or loss resulting from the temperature difference between the air flowing in a
duct and the surrounding air. The vapor barrier prevents condensation forming on
the outside of ducts carrying air at lower temperatures than the surrounding air.
