Insulated flexible duct hoses
An insulated duct keeps warm extract air from cooling inside the duct — which prevents condensation forming, dripping back into the fan and streaking the ceiling. It also dampens fan noise on its way to the terminal.
Available in 80, 100, 125, 150 and 200 mm diameters. Recommended for any extract run that passes through a cold loft space, and essential for HRV and heat-recovery systems.
