Each Floorwise underlay has unique performance characteristics, for which we have created a usage recommendation table to make comparing the underlays easier.
Please note that generally the thicker the underlay, the better the underfoot comfort, whilst the greater the density the better the underlay will perform over time.
The table includes a classification column which rates the usage of underlays according to guidance provided in the BS EN 14499 standard for underlays.
LD/U Light Domestic Use (Not Suitable for Stairs)
GD/U General Domestic Use
L/U Luxury Use
GC/U General Contract Use
HC/U Heavy Contract Use
Also included in the table are tog ratings, with some underlays being better insulators than others. Finally, there is an impact sound rating which is a guide to how well the underlay suppresses noise from the room above.
