Flexible ductwork comes in plain, lagged, and acoustic specifications. It is available in 10m lengths, and in a range of diameters from 100mm to 450mm. All our flexible ducting corresponds with EN 13180 specifications for flexible ducts. If junctions are needed this flexible ducting can be combined with our spiral fittings range, which also means it can also be  used in conjunction with regular spiral ducting should only a short flexible section be required.
