Description
Our range of plastic ducting is UK manufactured with top quality materials that will supply a durable product suitable for domestic and commercial systems
This horizontal 45 degree bend can be used to run your ductwork around obstacles, along walls and into ceilings and offers superior performance and durability over flexible alternatives.
Is designed to be low profile to fit inside ceilings, floor slabs, or to be concealed above kitchen wall units. It is best utilised as part of a ducting system for high powered cooker hood extractors and whole house ventilation systems, such as heat recovery systems or mechanical ventilation systems in offices, houses, and apartments.

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 PVC 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It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations
