Suitable Substrate for Cathedral Oak Plank flooring

When installed over any type of underfloor heating system it is critical that Cathedral flooring (CF) is bonded to a suitable substrate.

We do not recommend bonding (CF) direct to screed.

If the UFH system uses metal diffuser plates these must be in full contact with the overlaid floor for best efficiency.

A suitable underlay compatible with UFH should be installed between the plates and underside of the wood flooring to eliminate possible sound of the plates creaking against the flooring
