The strong thermal qualities of Econoboard help to prevent heat loss through the substrate, making it perfect for increasing the insulation of concrete and screed substrates.
Econoboard has a high compressive strength as well. When you combine this with minimum height build-up, you have the ideal board for installing underfloor heating systems on solid substrates.
When utilizing a flexible tile adhesive like Econofix, Econoboard has a specially prepared surface that provides an exceptionally strong bind to the substrate.

Frequently Asked Questions

Because heat flows evenly in all directions until it encounters a layer of thermal resistance, installing a layer of Econoboard Insulation Boards beneath the Underfloor Heating to act as a thermal resistance layer and prevent downward heat loss is highly recommended. Stopping this downward heat loss reduces the time it takes for the Underfloor Heating to heat up and can improve its efficiency by up to 50%. However, if this is not taken into account during the height construction, the heating will still work, but it will be less efficient and take longer to warm up.

Uncoated boards have an extruded polystyrene core with a fibre reinforced cement coating on both sides, whereas coated boards have an extruded polystyrene core with a fibre reinforced cement coating on both sides. The Coated Econoboard is designed to be used on a wooden substrate to offer lateral stability, whilst the Uncoated Econoboard is designed to be used on concrete.
