A quick and easy to fit system of semi-rigid ducting (Ø75mm (OD) 63mm (ID) x 50M roll in red) 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 pipes 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
• The round 75mm pipe takes 10 Kilonewton’s per square metre of pressure to crush it, therefore will stand most household items that are thrown onto it in loft spaces. It can even be buried in up to 3 metres of concrete
• 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 blue, to distinguish between supply and extract air on mechanical heat recovery ventilation systems. See part number: 90001379
