Multi Layer Aluminum Flexible HVAC Duct , Ventilation Fire
Resistant Flexible Ducting
Air ventilation system insulated pipe manufacture for HVAC system
is perforated along its entire length with micro perforations to
enhance acoustic performance. Using insulated ducting keeps the
noise from air movement down and also helps to keep your grow room
cooler when used with air cooled lights.
This is a range of fully flexible thermally insulated and Acoustic
ducting, which has been specially designed for the HVAC market and
hydroponic market , It has been developed to minimise the heat gain
or loss resulting from the temperature differential between the
airflow and the surrounding ambient air. The vapor barrier prevents
condensation forming on the outside of ducts carrying air at lower
temperatures than the surrounding air.
It is constructed with an inner duct with either 25mm fiberglass
insulation and covered with an outer jacket, which acts as a vapor
barrier. The jacket is a spirally produced multi-layer
Aluminum/Polyester laminated fabric reinforced with a fiberglass
yarn, which provides an outstanding combination of strength and
Commonly used for heat recovery units and when ducting through
attics to avoid condensation building up as hot, moisture laden air
