Flooring over underfloor heating in Crayford
Underfloor heating only works if the floor above it is spec'd correctly. Wrong underlay, wrong plank thickness or a sealed perimeter and the room stays cold. In Crayford we fit LVT, laminate and engineered wood rated for UFH, on underlay under 1.0 tog, with a proper expansion gap so the boards can move through the heating cycle.
