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. \u003cstrong\u003eUse approximately 1 clip rail per m² of floor area.\u003c\/strong\u003e\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pp-stat-bar\"\u003e\n    \u003cdiv class=\"pp-stat\"\u003e\n\u003cdiv class=\"num\"\u003e1m\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eLength per Rail\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"pp-stat\"\u003e\n\u003cdiv class=\"num\"\u003e~1 per m²\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eCoverage Guide\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"pp-stat\"\u003e\n\u003cdiv class=\"num\"\u003e200mm\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003ePipe Centres (15–16mm)\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"pp-stat\"\u003e\n\u003cdiv class=\"num\"\u003e16–18mm\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eCompatible Pipe Sizes\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eThe Clip Rail System — Overview\u003c\/h2\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n  \u003cp\u003eClip 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.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n  \u003cdiv class=\"pp-grid\"\u003e\n    \u003cdiv class=\"pp-card\"\u003e\n\u003cstrong\u003e📏 Accurate 200mm Pipe Spacing\u003c\/strong\u003eThe clip notches in the rail are pre-spaced at 200mm centres for 15\/16mm pipe, eliminating the need to measure and mark pipe spacing on site.

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.\u003c\/p\u003e\n  \u003cp\u003eUnroll 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).\u003c\/p\u003e\n\n  \u003cdiv class=\"pp-callout\"\u003e\n    \u003ch3\u003e📐 Quantity Calculation\u003c\/h3\u003e\n    \u003cp\u003eUse \u003cstrong\u003eapproximately 1 clip rail length per m² of floor area\u003c\/strong\u003e.

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.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"pp-faq-item\"\u003e\n    \u003ch3\u003eHow do I fix the clip rail to the insulation if it doesn't have its own adhesive?\u003c\/h3\u003e\n    \u003cp\u003eThe CLIPRL clip rail is fixed to the insulation using \u003cstrong\u003ePB02911 standard UFCH pipe clips\u003c\/strong\u003e — the same clips used to subsequently secure the UFH pipe within the rail.

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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pp-infobox\"\u003e\n    \u003cstrong\u003eℹ️ Related clip rail system products:\u003c\/strong\u003e \u003cstrong\u003ePB02911\u003c\/strong\u003e Standard UFCH Pipe Clip Pack of 250 (fixes rail to insulation and pipe to rail) · \u003cstrong\u003eUFH5015B–UFH15015B\u003c\/strong\u003e 15mm UFH Barrier Pipe Coils · \u003cstrong\u003eCPC1525\u003c\/strong\u003e 15mm Conduit Pipe Coil (manifold tails and bend former) · \u003cstrong\u003eCPC2225\u003c\/strong\u003e 22mm Conduit Pipe Coil (expansion joints) · \u003cstrong\u003ePB08576\u003c\/strong\u003e Red Floor Panel (alternative pipe positioning system for 100mm spacing or spiral layouts)\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Polypipe","offers":[{"title":"Default Title","offer_id":63633884152157,"sku":"CLIPRL","price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/1mtrLengthClipRailtofit16mm-18mmForUnderfloorHeating.jpg?v=1772129979","url":"https:\/\/qualityheating.co.uk\/products\/polypipe-ufh-clip-rail-1m-length-pipe-positioning-rail-for-16-18mm-underfloor-heating","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
