PhoneStar - Ceiling

The detailed PhoneStar Installation Instructions must be observed before you can install the boards.


To improve impact and airborne sound insulation PhoneStar should be screwed onto a substructure. The substructure (lathing of wood or better resilient bars) has to be screwed at a distance of 31.5 cm to wooden beams or solid ceiling. Spaces are filled in with mineral wool. PhoneStar is screwed into the substructure and is planked with plasterboard.
The direct attachment of the PhoneStar on the ceiling is possible.
