Polypipe Conduit Pipe Coil 15mm | Black Polypropylene UFH Pipe Sleeve | 25m & 50m
22mm Conduit CPC2225 / CPC2250 Black Polypropylene
The Polypipe 22mm Conduit Pipe Coil is a flexible black polypropylene sleeve designed to protect 15mm UFH barrier pipe where it passes through critical areas of the floor installation — including screed expansion joints, wall penetrations, and the transition from the insulated floor area to the manifold position. The 22mm internal bore provides the clearance needed to sleeve a single 15mm UFH pipe run, allowing the pipe to move freely within the conduit at thermal expansion joints rather than bearing directly against the screed edge — which would cause localised stress and potential pipe damage over time. Available in 25m (CPC2225) and 50m (CPC2250) coil lengths.
Available Variants — Select Length Above
| Coil Length | MPN | Inner bore | Best For |
|---|---|---|---|
| 25m | CPC2225 | 22mm | Smaller installations — fewer circuits, shorter manifold-to-floor runs |
| 50m | CPC2250 | 22mm | Trade size for larger systems with multiple circuits and expansion joint coverage |
What is Conduit Pipe and Why Is It Required?
In all water underfloor heating systems installed in solid or screeded floors, the UFH pipe must be protected in two specific situations.
1. Expansion joints: Screed floors contract and expand with temperature changes. Where a screed contains a structural expansion joint — a deliberate break in the screed to accommodate movement — any UFH pipe crossing the joint must be sleeved in conduit. The conduit allows the screed panels on either side of the joint to move independently without applying shear force to the bare UFH pipe. Without conduit at expansion joints, the pipe may be cut or crimped by repeated screed movement, causing eventual failure at the joint.
2. Wall penetrations and manifold tails: Where UFH pipe exits the floor area and rises to the manifold position — typically through the edge insulation strip and into a manifold cabinet or alcove — the pipe should be sleeved in conduit to protect it from contact with masonry, the screed edge, and any sharp edges at the floor perimeter. This conduit sleeve also makes the pipe replaceable in future without breaking out the floor structure.
Key Features
- Black flexible polypropylene — durable, flexible, and chemically resistant; compatible with screed, concrete, and standard construction environments
- 22mm internal bore — correct sizing to sleeve a single 15mm UFH barrier pipe with clearance for free movement
- Flexible coil format — easy to handle and cut to length on site; can be routed around corners in the floor construction if required
- Push-fit compatible — the conduit slides over 15mm UFH pipe for straightforward threading at the manifold connection point
- Available in 25m and 50m — choose the quantity appropriate for the project size
