What are the substrates

Cork backing made from crumb bark of cork, tightly pressed. It muffles sound well and evens out the base, serves for a long time, but requires waterproofing. There are varieties with the addition of rubber or bitumen.

Extruded polystyrene backing - issued in sheets of 3 and 5 mm thick. It holds heat well, does not rot and does not get wet. Muffles sounds, does not need additional waterproofing. There are also PPP substrates with foil coating.

Substrate Duplex - a special kind of substrates, consists of two layers of polyethylene with polystyrene granules between them. Due to the bottom film with holes it is able to ventilate, has high compressive strength, and is good for "floating" type of floors.

Foam polyethylene backing is the cheapest. It reduces noise well and is not afraid of moisture, but crumpled under heavy loads.
