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 8 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
