## Summary description

SpiroFlex double-wall duct 80/125 mm in white, length 1 m, model SX-TD80/125RB. Designed for ventilation and flue systems, the concentric 80/125 mm profile provides inner and outer conduits for combined air or exhaust flow and insulation/clearance. Suitable for residential and light commercial installations requiring a compact concentric duct section.

## Long description

SpiroFlex double-wall duct 80/125 mm in white, length 1 m (model SX-TD80/125RB) is a concentric duct section designed for ventilation and flue systems where an inner and outer conduit are required within a single compact profile. The 80/125 mm concentric arrangement provides a separate internal channel for exhaust or supply air and an external annular space that can be used for fresh air, insulation or clearance to combustible structures. The white finish makes this 1 m section suitable for visible installations in residential and light commercial interiors.
Advantages
This double-wall duct combines a concentric profile with a one-metre length for straightforward integration into stacked or linear duct runs. The concentric geometry simplifies installation where space or clearances are limited by allowing two flows within one assembly. The white surface facilitates visual integration into interiors and can be painted or covered if required. The product is designed to reduce the complexity of separate inner and outer ducts by providing both in a single component, which can cut installation time and minimize joint fittings.
Suitable for
Residential ventilation and balanced flue systems requiring a concentric 80/125 arrangement
Light commercial premises with compact duct routing or limited clearance to walls
Retrofit projects where replacing separate ducts with a concentric section reduces space needs
Installations that require a visible, finished white duct section of 1 m length
When it may not be suitable
This 1 m concentric section is not intended to replace full custom ductwork where extensive routing, bespoke bends, or multiple diameter transitions are required; complex systems may need additional fittings or sections. It is also not suitable where specific fire-rating, acoustic insulation, or chemical resistance standards beyond standard ventilation practice are mandatory, unless confirmed by project specifications.
Key specifications
Concentric diameters: inner 80 mm, outer 125 mm
Length: 1 metre
Colour/finish: white
Structure: double-wall/concentric profile providing inner and outer conduits
Typical applications: ventilation and flue/vent systems for residential and light commercial use
How to use
Position the 1 m concentric section inline with the existing duct run, ensuring correct orientation of inner and outer conduits for the intended airflows. Secure joints using compatible clamps or sealing methods recommended for ventilation and flue installations, and add flexible connectors or gasketed collars where movement or vibration is expected. Confirm clearance and sealing requirements around the outer conduit, and follow local codes for termination, support spacing and any insulation or fire-stopping where the duct passes through walls or floors.
What to consider before purchase
Confirm that the 80/125 concentric diameters match the rest of your system and any terminal devices
Check local building and flue-venting regulations for clearance, fire-stopping, and material suitability
Assess whether additional fittings (bends, reducers, supports, seals) are needed to complete the installation
Ensure the white finish and 1 m length fit the aesthetic and layout requirements of the project
Usage recommendations
Use this SpiroFlex concentric 80/125 double-wall section as part of a coordinated ventilation or flue installation. Maintain recommended support spacing, seal all joints to prevent air leakage, and verify correct airflow direction through the inner and outer conduits. For installations involving combustion appliance venting, follow appliance manufacturer guidance and local codes for safe clearances and termination.
