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.
Available Sizes
✔ 110x54mm

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