Instantor Rail-PRO™
Why Instantor Rail-PRO
The Rail System is a quick, easy to install UFH system embedded within the floor screed. Ideal for use in New Builds & Extensions where a solid floor construction is to be used.
The Rails come with an adhesive strip and are secured into position above the slip membrane/separating layer by removing the protective backing strip and laying the rail in position. It is recommended that rails are fixed at 1m intervals across the floor with pipe staples used every 500mm (in between rails) and where the pipe turns in any radii exceeding 45° to further secure the pipework to the insulation
For added fixing integrity pipe staples can be pushed through eyelets within the rail to ensure an enhanced fix to the insulation.
Once the rails are secured in position the underfloor heating pipework can be laid and affixed into the rails. The rail enables UFH circuit pipework to be spaced at a minimum of 150mm centres and UFH connection pipework to be spaced at 50mm centres.
It is recommended that all pipework is pressure tested prior to the laying of the screed. Where a liquid type screed is to be installed the slip membrane/separating layer should be sealed to ensure a watertight base is achieved.
