ISOMASTER A 23/20; 34/30; 45/40 sound insulation boards
Field of application As an impact sound insulation on intermediate ceiling in floated
screed structure.

Installation
The load-bearing capacity of the boards has to be taken into consideration at planning. After laying of the boards, a separating PE foil layer is necessary, if it will be covered by concrete. The thickness of this rigid screed above should be at least half as big as the insulation. In order to avoid sound bridges, along the connecting walls and around floor penetrations (e.g. pipes), minimum 5 mm thick ISOFOAM® border strip has to be installed.
Marking green line
