Econoboard coated insulation board

For superior floor rigidity and strength

Econoboard™ coated panels are strong and rigid to help you create the ultimate substrate for thin or thick bed tile adhesive and underfloor heating.

The boards are manufactured with a high-density extruded polystyrene core and a polymer-modified, glass fibre-reinforced cement coating on both sides to furnish superior rigidity and strength. This makes it an exceptional substrate for timber substrates.


Exceptional rigidity
and strength

Moisture and rot proof

High thermal insulation

Available in
thicknesses from
6mm to 50mm


Fix Econoboard directly to timber or metal studwork instead of plasterboard, or use them to replace ply when strengthening floors. They can also be used to cover old tiles and plaster on walls instead of removing the ‘old surface’ and re-plastering.

  • Superior tiling substrate
  • Cut heat loss by over 50%
  • Lightweight and easily cut for a fast install
  • Strengthen timber floor for tiling
  • Replaces wet finishes
  • Ideal for underfloor heating
  • Maximise underfloor heating efficiency

Using with timber floors

Timber floors generally need strengthening before they are tiled over. Even the minimum thickness of 6mm Econoboard Coated can provide this strength as long as it’s fixed with a flexible cement-based tile adhesive and mechanically fixed at 300mm centres. Thicker boards of Econoboard can be fixed with adhesive or screws and washers.

Using with concrete floors

Because solid concrete floors transmit cold and damp from below and act as a ‘heat sink’ drawing the heat away from the room, placing Econoboard between the concrete and the tiles is a smart energy-saving choice.

Ensure the floor is free of dust or loose materials before fixing Econoboard. If your adhesive manufacturer recommends it, first treat the floor with a suitable primer for maximum adhesion.
