wittenberg 4.0 Serie

Concrete installation case

The concrete installation case made of Fermacell turns our wittenberg surface-mounted spotlight wi4-ab-1e-hb into a built-in concrete spotlight.

The Fermacell case made of 18 mm thick gypsum fiberboard is suitable for casting in concrete or for installation in plasterboard structures. The edges are chamfered on 4 sides.


Not suitable for exposed concrete! The installation housing must be fixed to the formwork by means of a base plate (internal dimension of the Fermacell case) to prevent it from slipping and the cavity must be filled with hard foam to relieve pressure.
