In Screed Cable 180W/M²

Product Overview

The In-Screed Heating Cable is a versatile underfloor heating (UFH) solution designed for new builds and extension projects.

It is installed within a screed substrate to provide efficient and even heating under any type of floor finish.

• Suitable for any room or zone regardless of size
• Installed within 50–100mm cement or sand-and-cement screed
• Compatible with most floor coverings (Tile, Stone, Engineered Wood, Laminate, LVT and even Carpet)

Installation Recommendations

For maximum efficiency and quicker response times:

• Lay directly onto Celotex or Kingspan insulation boards
• Alternatively install on:
  • Cement-Coated Tile Backer Boards
  • XPS Insulation Boards

Fixing Options:

• Use In-Screed Cable Clips for insulation layers 50mm+
• Use Decoupling Mats to space the cable evenly before screeding
• Kit includes high-adhesion fixing tape and step-by-step installation instructions

Performance & Efficiency

• Can act as a comfort/secondary heat source alongside radiators
• Can serve as primary heating if 90–100% floor coverage is achieved
• Cable spacing dictates output:
  • 70mm spacing → approx. 260W/m²
• Controlled by a floor sensor thermostat for best efficiency
• Faster heat-up times compared to water-based UFH

Electric vs Water UFH

• Electric UFH is highly efficient when correctly installed and controlled
• Electric control: Floor sensor probe
• Water system control: Air sensor thermostat
• Electric UFH provides faster response and more accurate floor heating control
