Knauf Shaftwall: Shaftwall SW3/13
Knauf Shaftwall is our innovative system to form enclosures around service and lift shafts while working from one side.
Knauf Shaftwall is suitable for situations where access from one side is restricted, giving a high fire performance whilst being simple to construct.
Features and benefits:
- Quickly constructed from one side.
- Up to two hours fire resistance.
- Robust.
- Proven in tall buildings across the UK.
- Uses unique Knauf ‘C-T’ Stud.
To be installed in accordance with Knauf’s recommendations and British standards BS 8212-1995 and BS 8000-8:1994.
