This flexible duct has thermal insulation to prevent condensation in Heat Recovery Systems or where there is a temperature differential, for example where warm air is extracted through a cold void.

It will retain heat when taking warm air to a heat recovery system and back to the rooms when the heat exchanger is in a cold void such as the loft.

• Maximum air velocity 30 m/sec.
• Maximum pressure 2,500 Pa.
• Available in diameters - 100mm - 400mm
• Supplied in 10m lengths which can be cut on-site
