Every floor needs a good foundation. Before you start installing your new Pergo commercial grade wood floor, you must select an underlay. It will add not only walking comfort, but also functionality to your floor. A great floor requires an underlay that will retain its properties over time.
Impact sound is the sound heard in the room below when someone walks on the floor. All Pergo underlays either meet or exceed requirements for impact sound insulation.
When installing a floor in combination with an underlay over underfloor heating, the thermal resistance of the total installation should ideally not exceed 0,15 m² K/W. If exceeded, the effect of the underfloor heating might be slightly reduced.
Walking noise is the sound heard in the room from walking on the floor. The higher the emitted walking noise reduction value, the better the sound reducing property of the underlay.
Pergo wood floors must be protected from moisture rising up from below. A vapour barrier offers resistance against passage of water vapour, which is necessary when the wood floor is installed on a mineral subfloor, such as concrete.
