Installation Guide

For optimal airtightness & durability:
Apply plastic ducting sealant to the male fitting.
Push fittings together.
Secure with aluminium duct sealing tape.
Alternatively, self-sealing fittings can be used – reducing installation time by up to 70%.

Insulation of Ductwork

If installed in a cold area (e.g. loft space), insulation is required.
Required insulation: 25mm thickness & thermal conductivity of 0.04W/(m.k) or lower.
How to insulate ducting: Wrap with 25mm duct wrap (silver foil face) & Use 25mm rockwool.
Bubble wrap insulation is no longer compliant with building control regulations.

For larger ducting, we recommend using metal spiral ducting and fittings due to their superior strength.
