Polypipe UFH Clip Rail 1m Length | Pipe Positioning Rail for 16–18mm Underfloor Heating
CLIPRL 1m Length Fits 16–18mm Pipe Solid / Screeded Floors
The Polypipe UFH Clip Rail (CLIPRL) is a 1m length black plastic track used in the Polypipe clip rail solid floor underfloor heating system. Rows of clip rail are fixed across the insulation layer at 1m intervals using PB02911 pipe clips, creating a grid of tracks that the UFH pipe is clipped into at 200mm centres. The clip rail holds the pipe in its serpentine layout at the correct spacing and slightly elevates it above the insulation, ensuring full screed encapsulation for optimum heat transfer. Each 1m length can be clipped to adjacent lengths to extend runs, and can be cut to fit at room perimeters. Suitable for 16mm and 18mm UFH barrier pipe. Use approximately 1 clip rail per m² of floor area.
The Clip Rail System — Overview
The clip rail system is one of Polypipe's two methods for solid floor underfloor heating — the other being the Red Floor Panel system (PB08576). Whereas the Red Floor Panel uses a pre-formed castellated grid to position the pipe, the clip rail system uses slim plastic strips (the clip rails) fixed to the insulation at regular intervals, with the pipe clipped into the notches in the rail surface. This approach is generally considered the more traditional of the two methods, and offers some practical advantages: the clip rail system uses less material on site than floor panels, stores more compactly, and is slightly faster to install in regular rectangular rooms where the serpentine routing is straightforward.
Clip rails are laid perpendicular to the intended pipe run direction, at 1m spacing across the insulation. The UFH pipe is then laid in a continuous serpentine pattern, clipped into the rail notches at 200mm spacing for 15–16mm pipe (200mm or 300mm for 18mm pipe), and bent through 180° at circuit ends using PB02911 clips to secure the bends. A screed is then poured over the assembly.
Key Features & Benefits
Installation Guide — Clip Rail System
Begin by installing rigid insulation boards across the full floor area and fitting edge expansion strip around the room perimeter. Lay clip rail strips across the insulation perpendicular to the intended pipe run, at 1m intervals — i.e. parallel rows of clip rail spaced 1m apart across the full room width. Use PB02911 pipe clips to anchor each rail strip at 200mm intervals along its length, pressing the clips through the rail into the insulation. Continue laying rails until the full floor area is covered. Leave sufficient clearance at the room perimeter (typically 150–200mm) to accommodate pipe return bends.
Unroll the UFH pipe coil from the outside of the coil and begin laying at the manifold connection point. Route the pipe through the conduit sleeve (CPC1525) at the manifold tail position and across the floor in a serpentine pattern, clicking the pipe into the rail notches at 200mm centres. At each circuit end, bend the pipe through 180° — keeping the bend edge parallel to the adjacent circuit — and secure with PB02911 clips through the insulation. Return the pipe along the adjacent rail row in the opposite direction. Continue until the circuit is complete. Connect circuit tails back to the manifold. Pressure test before screeding. Screed to optimum depth of 65mm from insulation surface (40mm above pipe top).
📐 Quantity Calculation
Use approximately 1 clip rail length per m² of floor area. For example: a 25m² room requires approximately 25 CLIPRL lengths. Additionally order 1 pack of PB02911 pipe clips (250) per 50m² of floor area — the same clips fix both the rail to the insulation and the pipe within the rail. Add 10–15% to both quantities to allow for cuts, pipe bends, and perimeter runs.

Frequently Asked Questions
Can I use this clip rail with 15mm Polypipe UFH pipe?
The CLIPRL clip rail is specified for 16mm and 18mm pipe. Polypipe's 15mm UFH barrier pipe (UFH5015B etc.) can also be used in the clip rail system — the pipe will clip into the rail notches, which are sized to hold 15–18mm pipe securely. For 15mm pipe, use 200mm pipe centres. The important distinction is that if you are using 15mm pipe with the clip rail system, you are following the standard clip rail installation method — the Red Floor Panel (PB08576) is an alternative that provides 100mm spacing capability for higher-output applications.
How do I fix the clip rail to the insulation if it doesn't have its own adhesive?
The CLIPRL clip rail is fixed to the insulation using PB02911 standard UFCH pipe clips — the same clips used to subsequently secure the UFH pipe within the rail. Push one clip through the clip rail body into the insulation at 200mm intervals along each rail length. The clip anchors the rail flat against the insulation and also creates the fixing point for the pipe when laid. No additional adhesive or fixings are required.
Can the clip rail be used with the Red Floor Panel system in the same installation?
The two systems are alternative methods for the same application and are generally not mixed in the same floor area. However, in practice, clip rail can be used in irregular or awkward areas of a floor (around columns, in narrow alcoves) where cutting floor panels would be wasteful, while panels are used in the main open floor area. This is an installer preference decision and does not affect system performance provided pipe spacing and circuit lengths remain within the specified limits.
