Round Metal Ducting

Round Metal Ducting Galvanised spiral metal, available in different sizes, and available in 1 meter lengths. Duct length can be joined using Metal Male Duct Connectors. Manufactured in the UK Key Features Pipe ends are female and will accept male fittings such as bends and grilles. Lengths of duct channel can be joined together using a male connector. Easy to install and durable, just push-fit duct and fittings together. Compatible with most other manufactures Extensive range of fittings, outlets, and grilles available Galvanised male coupling, used to join circular ducts or other female fittings Fittings are produced in accordance with DW144 with a zinc coating weight of 275g/m2, and have a rolled edge for safer handling and improved alignment Compatibility Compatible with most other lead manufacturers for galvanised metal ducting  Performance Solid rigid ducting is suitable for use in all buildings to provide superior airflow performance vs. comparative size rectangular or flexible pvc or aluminium duct. Suitable to use in compliance with Part F Building Regulations. Installation To provide the best performance in airtightness and durability we recommend You provide greater mechanical strength to a joint by using a combination of plastic ducting sealant and aluminium duct sealing tape Apply duct sealant to the male fitting Push together Apply aluminium duct sealing tape over joint Alternatively, you can use self-sealing fittings that speed up the time taken by up to 70% and can be easily dismantled Insulation of Ductwork It is important that any ducting located in a cold area (e.g. loft space) to be insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/(m.k) or less. This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space. If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm rockwool It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations Sizes Round metal ducting is available in 100mm,125mm,150mm, 180mm & 200mm, and can one in one meter and two metre lengths.
