Shaft wall
■
ShaftWall provides a lightweight, fire resistant structure
to protect elements in confined spaces wherever access is
limited to one side only.
■
The system provides a protective structure which can be
incorporated at an early stage of the construction without
the need for scaffolding.
■
The structure is composed of steel profiles (Gypframe)
and plasterboard (Gyproc). The Gyproc CoreBoard plas-
terboard is inserted into the profile on the side of the
shaft, and the profiles are lined with Gyproc FireLine
plasterboard on the visible side.
