Installation of plasterboard cover ELS-PB

The ELS-PB plasterboard cover is used for covering gaps in case of casing cut-outs which have been uncleanly
plastered, tiled or if they are too large, which cannot be completely covered by the inner facade.
The plaster cover is fixed between the wall/ceiling and ELS inner facade.
