JG Underfloor Spreader Plates (From Above) is an underfloor heating (UFH) pipe fixing system designed for use with timber suspended or floating floors, where a low height build up is required. 15mm pipe is installed into single or double grooved aluminium spreader plates that transmit heat evenly across the floor. insulation is placed in the void below the plates to minimise downward heat loss. Ideal for new builds, extensions and renovations, especially first floor levels. For existing floor structures install between battens and for new floors, fix between existing joists. If the floor can be raised, floors can also be counter-battened to make installation even easier.
