What do I have to observe when installing a toilet with a SupraFix 2.0 fastening in combination with a soundproofing mat?

First of all the SupraFix 2.0 fastening brackets are mounted on the wall and then the soundproofing mat is fitted. The mat should not exceed a material thickness of 5mm. We recommend the Villeroy & Boch soundproofing set 9222 87 00 as it meets these requirements. Furthermore, it is made of exceptionally high-quality material with a high restoring force and has a practical SupraFix pre-perforation so that no time-consuming cutting is required.
