The Warmup Metro System is designed for use within either a floating or a bonded screed floor. The Metro Rail allows for quick, consistently spaced installation of the pipework prior to laying either a standard or a proprietary screed. The Metro Rails have integral clips spaced at 50mm intervals which provide a level of installation precision which is difficult to achieve with the Clypso System. They offer a robust fixing mechanism that is resistant to disruption from site traffic ensuring that the finished system matches the design and performs as it should. For bonded screed floors they are simply laid over the primed pre-insulated subfloor before applying the screed. The rails are laid perpendicular to the planned pipe direction, their backing is peeled off and they adhere to the floor, starting 200mm off the wall and then laid parallel at 1m intervals. The pipe is then clipped into place.
