Underlay Systems

Glued, nailed or floating? Parquet can be installed on most types of flooring. Choose the right underlay!
Choosing the right underlay is important. A hardwood floor underlay has to be of good quality to reduce movement and risk of squeaks. In addition, you get an underlay with very good audio characteristics.

Good to know

  • The sub-floor must be dry, level and self-supporting. Concrete sub-floors must be level and devoid of cement lumps, etc. The tolerance limit ± 3 mm per 2 running metres. For the UK: ± 3 mm over 3 running metres according to British Standard BS8204.
  • Moisture barrier: The floor must not be exposed for moisture from the sub-floor. An additional 0.2mm plastic foil has to be used on concrete floor to insulate against any remaining dampness.
  • Impact sound: Structure-borne noise inside neighboring rooms when walking on the flooring.
  • Walking sound: Noise generated inside the room itself when walking on the flooring.
  • Load resistance: An underlay with higher density or higher dynamic load reduces movement and the risk of unwanted sound both in the room itself and in neighboring rooms.
