Uncoated Insulation Board For Concrete Substrates


Regular price $199.00 Sale

Uncoated Econoboard provides the perfect, insulated substrate for Underfloor Heating

Uncoated Econoboard provides the perfect, insulated substrate for tile adhesive and Underfloor Heating and dramatically improves efficiency of Underfloor Heating systems.

Econoboard has a very high compressive strength coupled with minimal height build up, making this unique board perfectly suited for use with our Underfloor Heating systems on concrete substrates.

Econoboard has a specially prepared surface to provide an ultra-strong bond to the concrete substrate using a flexible tile adhesive.

    How much do you need?
    To work out how much Econoboard is required the total floor area of the room needs to be calculated. This number is likely to be higher than the square meters of the floor heating as the Econoboard needs to cover the entire floor. 

    The Econoboard insulation boards are 1.2x0.6 meters and cover an area of 0.72m² therefore divide the total floor area by 0.72 to calculate the number of sheets required.

    As the insulation boards come in boxes of 10 divide the number of sheets required by 10 and then round this up to determine the number of boxes required.

    Econoboard & Concrete Floors

    • Before fixing Econoboard to any floor make sure the surface is free from dust or any loose materials.
    • Econoboard should be adhered using a single part, flexible cement-based adhesive. If your adhesive manufacturer recommends it, treat the floor with a suitable primer to ensure good adhesion.
    • Solid concrete floors transfer the cold and damp from below, so Insulation Boards should be used before tiling to take advantage of its excellent thermal properties. It is particularly beneficial when installing underfloor heating onto a concrete substrate, as heat travels equally in every direction until it reaches a barrier.

    Boost Efficiency by up to 50%
    The thermal properties of Insulation Boards minimise the amount of heat lost through the substrate, making your underfloor heating system up to 50% more efficient.
