Description
Galvanised spiral metal, available in different sizes, and available in 1-meter lengths.
Duct length can be joined using Metal Male Duct Connectors.
Compatibility
Compatible with most other leading 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) 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 the 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It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations
