What the TÜV seal says about our underlays

The sign for tested quality applies to products that have been tested by TÜV Rheinland and offer good performance in three essential areas: quality, functionality and usabilityt.

Our underlays in the series SELITPRO® TwinFoam™, SELITAC®, SELITFLEX® and SELITBLOC® are the first TÜV-tested underlays in the world.
