What is the difference between Ekoboard and Construction boards?

Both Ekoboard and Construction board (Marmox) have the same high insulation and compression properties, the difference is that a construction board has a cements/mesh layer either side of an inner insulation board, making it more ridge than an ekoboard.  This means it is perfect to be installed on top of uneven non solid floor such as old floor boards.

If you have a solid floor such as concrete, plywood, chipboard or similar Ekoboards are perfect as you will get the rigidity needed from the existing floor base.

Uheat supplies many different thickness of insulation boards supplied as Ekoboards 6mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm.

Construction board as Marmox 6mm, 10mm, 20mm, 30mm, 40mm, 50mm and 60mm  all have a very high compression strength, a good indication of this strength is that you will be able to push your nail into the board but you will not ever be able to dent any of the boards pushing you whole hand into it as a spread weight.
