■
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.
Gypframe 60, 70 or 92mm ‘I’ Stud framework with Gy-
proc CoreBoard between studs, secured by Gypframe
Retaining Channel. 25mm Isover Acoustic Partition Roll
(APR 1200) in cavity (optional). Lining boards to non-
shaft side, see table below. Studs at 600mm centres.
