A good floor needs a good underlay: High quality underlays guarantee you will enjoy your floor finish for a long time. We generally recommend insulating underlays for all hard substrates. They increase the elasticity of the floor and compensate for small irregularities in the substrate. They also absorb both impact sound and airborne sound in the room – good for your ears and those of your neighbours! Good for your floor, too, because the insulating underlay literally nestles between the engineered flooring planks and the hard screed.
The demands on the underlay material are as different as the underlays and the floor. Reducing footfall noise and moisture protection, as well as the operation of a hot water underfloor heating system, play a role here.
