Pre-Insulated HDPE Semi-Rigid Radial Ducting

Pre-Insulated HDPE Semi-Rigid Radial Ducting — Coiled Insulated Fresh Air Pipe

Pre-insulated HDPE semi-rigid radial ducting supplied in coils. The semi-rigid core holds its shape while still bending by hand, so long radial runs can be pulled from a manifold to each room with very few joints. A factory-applied insulation layer removes the need to lag the pipe on site, which saves both labour and the risk of a section being missed.

Key Features

• Factory insulated — consistent insulation coverage along the whole coil
• Semi-rigid core — holds shape yet bends around obstacles without fittings
• Coiled supply — long uninterrupted runs mean fewer joints and less leakage
• Radial layout friendly — designed for manifold-to-room topology
• Fast installation — unroll, route, connect

Technical Specifications

Typical Applications

• Radial (home-run) fresh air layouts from a distribution manifold
• Long concealed runs through ceiling voids and service shafts
• Projects where site labour for lagging must be minimised

System Matching

Designed to work with our EPP air distribution boxes and ABS distribution boxes, plus straight couplings and reducers.

FAQ

Q: Why radial layout rather than trunk and branch?
A: Radial runs are individually ducted to each terminal, which makes balancing easier and reduces cross-talk between rooms.

Q: How long are the coils?
A: Please confirm the coil length required for your project with our sales team.

Q: Can it be used for exhaust as well as supply?
A: Yes, the ducting is suitable for both.
