Polypipe UFH Ultra Flexible Barrier Pipe Coil 15mm | Underfloor Heating Pipe | 50m–150m
15mm Barrier Pipe UFH Only — Not for Plumbing EN ISO 15876 / EN ISO 21003
The Polypipe UFH 15mm Ultra Flexible Barrier Pipe Coil is the standard pipe for all Polypipe solid floor underfloor heating installations — panel system, clip rail system, and staple systems. Made from highly flexible polybutylene with an integral oxygen barrier layer, it is significantly more flexible than standard plumbing barrier pipe, reducing installation effort and enabling tight routing in complex floor layouts. Available in five coil lengths — 50m, 80m, 100m, 120m, and 150m — allowing exact sizing to the circuit requirement. This pipe is for underfloor heating use only and must not be used for potable water, domestic hot water, or gas pipework.
Available Variants — Select Length Above
| Coil Length | MPN | Typical Circuit Coverage | Best For |
|---|---|---|---|
| 50m | UFH5015B | Up to 11m² @ 100mm / 22m² @ 200mm | Single rooms, bathrooms, single circuits in smaller zones |
| 80m | UFH8015B | Up to 18m² @ 100mm / 35m² @ 200mm | Medium rooms, one to two circuits, avoids excess waste on smaller projects |
| 100m | UFH10015B | Up to 22m² @ 100mm / 44m² @ 200mm | Most common trade size — single long circuit or two shorter circuits |
| 120m | UFH12015B | Up to 26m² @ 100mm / 53m² @ 200mm | Larger rooms requiring up to two full-length circuits |
| 150m | UFH15015B | Up to 33m² @ 100mm / 66m² @ 200mm | Large open-plan areas, multi-circuit zones, best per-metre value |
Maximum single circuit length: 100m (inclusive of connection tails to and from the manifold). Do not exceed 100m per circuit — longer circuits cause excessive pressure drop and uneven flow distribution across the manifold. For areas exceeding 100m of pipe, split into multiple circuits on the manifold.
Why Ultra Flexible?
Standard polybutylene barrier pipe — as used in conventional plumbing — is designed to be self-supporting and relatively rigid. This makes it easy to run in straight lines but difficult to route through tight bends and complex patterns. Underfloor heating requires the opposite: pipe needs to be laid in continuous serpentine or spiral patterns with small-radius bends repeated dozens of times across the floor area.
Polypipe's UFH Ultra Flex pipe is specifically formulated for this application. It is significantly more flexible than standard plumbing grade barrier pipe, allowing easy routing through the castellations of the Red Floor Panel (PB08576), over the clip rail (CLIPRL), or across the floor with a staple gun, with minimal effort and without the pipe trying to spring back. When unrolling, take the pipe from the outside of the coil and unroll in the direction of travel — this prevents twisting and kinking. The Red Floor Panel guides ensure the minimum bend radius is automatically maintained, eliminating the risk of pipe deformation at bends.
Key Features & Benefits
Coverage Calculation Guide
Use the following material requirements to estimate pipe quantities:
| Pipe Centres | Pipe Required | Max Coverage per 100m Circuit |
|---|---|---|
| 100mm | 8.2m of pipe per m² | Approx 11m² (plus tails) |
| 200mm | 4.5m of pipe per m² | Approx 22m² (plus tails) |
| 300mm (18mm pipe only) | 3.3m of pipe per m² | Approx 30m² (plus tails) |
Always add 5–10m per circuit for connection tails (manifold to floor entry and exit, via conduit pipe CPC1525). Do not plan circuits longer than 100m inclusive of tails.

⚠️ Important — UFH Pipe is Not for Plumbing
This pipe is engineered specifically for underfloor heating circuits. It must not be used for potable cold water supply, domestic hot water, gas or oil supply, or compressed air pipework. These applications require differently rated pipe materials. UFH barrier pipe used in plumbing applications may not comply with WRAS requirements for drinking water contact and could present a safety risk. Always use appropriate pipe for each application.
Frequently Asked Questions
How do I choose the right coil length?
Calculate the pipe required for your circuit area (floor area in m² × pipe density per m²) and add 5–10m for connection tails. Choose the next coil size up. For example: a 15m² floor at 200mm centres needs 15 × 4.5 = 67.5m of pipe, plus 8m of tails = 75.5m total — specify the 80m coil. Avoid over-specifying; excess pipe that has been unrolled cannot be re-used in the system as a partial circuit of reduced length would create flow imbalance.
Can I join two coils together in one circuit?
No. UFH circuits must be continuous runs of pipe with no joints within the floor structure. Joints in buried pipe create an unacceptable risk of leaks after screeding, which would require breaking out the screed to repair. Each circuit should be a single unjoined coil from manifold to manifold. The maximum circuit length of 100m prevents the need for any mid-circuit joints in practice.
Can I use this pipe with the Polypipe Overlay system?
No. The Overlay system uses 12mm barrier pipe (UFH5012B / UFH8012B). The Overlay floor panels and end returns are grooved for 12mm pipe only. The 15mm pipe is for solid screeded floor applications (panel system and clip rail system) where 15mm and 18mm pipe sizes are used. Using 15mm pipe in Overlay panels would prevent correct installation and panel joints from seating.
