Indoor installation

Compact design and small footprint, top connections via double lips circular connectors (except size 52) for an easy, quick, airtight and cost-efficient installation (no adapters).

Insulation of Ductwork

We recommend you use Metal Spiral ducting and fittings due to superior strength

To provide the best performance in airtightness and durability we recommend You provide greater mechanical strength to a joint by using self-sealing fittings or a combination of Ducting Sealant and Aluminium Duct Sealing Tape

  1. Apply Duct sealant to the male fitting
  2. Push together
  3. Apply Aluminium Duct Sealing Tape over joint 

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It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations


In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.
