1m interlocking grip rail can be stuck directly to insulation boards and hold 16-20mm underfloor heating pipe tightly in place prior to screeding. Grip rails slightly elevate the pipe above the insulation so no contact is made which allows the screed to flow underneath and cover the pipe completely for a better heat exchange, minimizing heat loss into the boards. Each rail can be held down in a number of ways, using the sticky strip on the back, screwed or clipped using barbed pipe clips.
The self adhesive strip on the back makes placement quick and easy without any fuss- peal off the protective strip and put in place. ‘Click’ pipe into the rail for a tight and secure hold ready for screeding.
Grip rails help shorten installation time by helping with correct and regular pipe spacing without needing to continually measure distance.
