Key Benefits of Cement Boards for UFH & Tiled Floors

Stable Tile-Ready Surface Cement and gypsum fibre boards provide a strong, stable base for ceramic, porcelain, stone and tile floor finishes.
Moisture-Resistant Performance Cement-based panels are well suited to bathrooms, kitchens, wet rooms and damp-prone areas where timber-based boards may not be ideal.
Low-Profile Dry Screed Systems Dry screed cement boards help reduce floor build-up compared with traditional screed installations while still providing strength and stability.
Efficient Heat Transfer Cementitious materials help conduct heat effectively, supporting even heat distribution from underfloor heating systems.
Routed & Flat Board Options Choose routed boards for pipe channels or flat cement boards for covering grooved boards and creating a tile-ready surface.
Trade & Domestic Use Suitable for installers, contractors and homeowners fitting underfloor heating in kitchens, bathrooms, renovations and tiled rooms.

Routed Cement Boards, Flat Cement Boards & Gypsum Fibre Panels Explained

Cement boards and gypsum fibre panels are used to create strong, stable and heat-conductive floor build-ups for underfloor heating. Routed boards include pre-cut pipe channels for UFH pipe, while flat dry screed cement boards are used as a covering or overlay layer. Gypsum fibre structural panels provide load-bearing floor support and can be used where a robust UFH-ready board is required.

Board Type What It Does Best For
Routed Dry Screed Cement Board Holds 12mm UFH pipe in pre-cut channels and creates a low-profile dry screed UFH layer. Low-build-up water UFH systems and tiled floor build-ups.
Flat Dry Screed Cement Board Creates a stable overlay or tile-ready surface above routed boards or UFH build-ups. Covering grooved boards, tiled floors and moisture-resistant floor construction.
ProTile20 Cementitious Panel Combines insulation and a cementitious tile-ready panel surface. Direct tile UFH installations, bathrooms and high-use tiled areas.
Gypsum Fibre Structural Floor Panel Provides a load-bearing floor panel suitable for UFH-ready structural floor build-ups. Structural dry floor systems, robust overlays and renovation projects.

Best Uses for Structural & Routed Cement Boards

Bathrooms & Wet Rooms Cement boards are useful in wet areas because they resist moisture and provide a stable substrate for tile floor finishes.
Kitchens & High-Traffic Areas Strong cementitious and gypsum fibre boards help create durable tiled or structural floors in busy household spaces.
Low-Profile Water UFH Routed dry screed boards and ProTile20 panels help create low-build-up water underfloor heating systems without traditional screed depth.
Tile & Stone Floor Finishes Cement boards and tile backer boards provide a suitable base for ceramic, porcelain, stone and similar hard floor finishes.

Frequently Asked Questions

What are cement boards used for in underfloor heating? Cement boards are used to create a stable, moisture-resistant and heat-conductive floor layer for underfloor heating systems, especially where tiled or stone floor finishes are being installed.
What is a routed dry screed overlay board? A routed dry screed overlay board has pre-cut channels for underfloor heating pipe, allowing a low-profile dry UFH system without a traditional wet screed pour.
Can cement boards be tiled over? Yes, selected cement boards and tile backer boards are designed to accept ceramic, porcelain or stone tiles when installed with the correct adhesive, primer and preparation.
Are cement boards suitable for bathrooms? Yes, cement-based boards are commonly used in bathrooms, kitchens and wet areas because they are stable and moisture resistant compared with timber-based floor boards.
What is the difference between routed and non-routed cement boards? Routed boards include grooves for UFH pipe. Non-routed or flat cement boards are used as cover boards or structural overlay layers to create a stable surface for the final floor finish.
