Metro Rail System uses pre-moulded retention clips. The rail is located on top of the insulation layer and is separated by a plastic membrane. The Metro Rail System allows pipes to be spaced at 50mm intervals.

The system holds the pipework into place until the screed is applied. UltraTile from Instarmac provides one of the best screeds on the market for this purpose. It is suitable for almost any floor finish and in particular where the flooring (wood, carpet or vinyl) may be replaced from time to time.
