Plafotherm DS Tabs ceiling element

Name: Plafotherm DS Tabs ceiling element
Brand: Lindner Group

Description

Metal ceiling raft for buildings with concrete core activation, with acoustic fleece and an optional acoustic insert. The raft is connected to the activated structural concrete ceiling in a thermally conductive manner. The efficiency is 94 to 98 per cent when the raft area occupies 30 per cent of the room area, and 90 to 97 per cent at 50 per cent coverage.
