Tella Grid System uses a wire grid to which the underfloor heating pipe is attached using plastic cable ties. The wire grid is typically used to add structural support to the subfloor where extra strength is required due to high floor loadings.

The Tella Grid System is suitable for almost any floor finish and in particular where the flooring (wood, carpet or vinyl) may be replaced from time to time.
