To gain an accurate comparison, measure the cost of installation per square metre of floor rather than the cost of material per tonne or metre cubed. Because you can lay, Gypsol screeds are much thinner than conventional sand cement screeds more square metres of the floor is covered. For example, a sand/cement floor screed without underfloor heating laid on insulation should be at least 65mm deep. In this example, it means that you can only cover 15 square metres with one cubic metre of material. However, the same floor laid using a Gypsol floor screed at 40mm deep would cover 25 square metres. This also allows the potential to change insulation types to more cost-effective options, offering significant cost savings for your floor.
