A quick and easy to fit system of semi-rigid ducting (Ø75mm (OD) 63mm (ID) x 50M roll in blue) that can result in up to 70% time saving during the on-site installation process, compared to rigid or spiral duct methods.

KEY FEATURES:

• The duct lining is made from new raw material (not recycled) and is anti-static, non-porous and odourless, this lining helps reduce dirt deposits and has other characteristics such as low air-flow resistance and has high sound absorption
• Access panels on the distribution boxes so that the ducting system can be easily cleaned out. (As required and stated in the 2010 Domestic Ventilation Compliance Guide)
• No noise transfer (talking, music etc) between rooms (As required and stated in the 2010 Domestic Ventilation Compliance Guide)
• No noise generated by high volumes of air being pushed or sucked down ducting (common with branch systems)
• No joins in ducting so it cannot become dislodged if knocked or disturbed e.g., in loft spaces
• Quicker and easier to install compared to traditional branch systems
• Bespoke insulation available for unheated areas
• Metal attenuated (noise absorbing) distribution boxes – very robust and durable, various sizes
• Also available in red, to distinguish between supply and extract air on mechanical heat recovery ventilation systems. See part number: 9041130
