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 system can also be built horizontally to provide a fire-rated membrane. StairWall is a derivative of the ShaftWall system, which is used to protect stairwells.

INSTALLATION OVERVIEW
1-floor-ceiling-and-starter-channels

Gypframe Channel is fixed to the structure and Gypframe Starter Channel to vertical abutments. (Please reference to the relevant performance tables for head channels) 

2-insert-i-studs

Gypframe "C" Studs are fitted vertically to friction-fit within the channel sections and to abutments, to form the framework. 

3-insert-coreboard-between-i-studs

Gyproc FireStop board linings are fixed to the non-shaft side of the frame.

4-insert-retaining-channel

Gyproc FireStrip is used in a continuous line to seal at the head.

5-apply-sealant-to-perimeter.

Pressurised shafts and service ducts are also sealed using Gyproc Sealant. This is applied to all board-to-metal junctions.

6-fixing-plasterboard

Deflection is accommodated at the head by incorporating plasterboard fire-stops cut on site.
