This Macclesfield extension needed underfloor heating without a deep screed. We supplied cement-faced XPS overlay boards with 16mm pipe, routed back to a new manifold, with Heatmiser thermostats so every zone runs from the app.

The system

  • Floor system: Cement-faced XPS overlay boards
  • Pipe: 16mm pipe
  • Controls: Heatmiser app-controlled thermostats

Why cement-faced overlay

Cement-faced boards give a hard, flat surface that tiles or flooring can go straight onto, and they add far less height than a screed. The XPS core insulates below the pipe, so the heat goes up into the room.
