1 Maximum heights and fire resistance:
Calculated based on a limiting deflection of L/500 at 200 Pascals (0.2kN/m2).
Relate to the fire resistance of system in accordance with BS 476: Part 22: 1987 only.
2 Acoustic sound reduction dB (Rw)
Systems tested in accordance with BS EN ISO 10140-1:2010+A2:2014.
3 Period in minutes: inclusive of Integrity & Insulation
Note: System performances for both fire resistance and sound insulation performances are for imperforate partitions, incorporating plasterboard/AQUAPANEL® Indoor with all outer joints taped and filled, in accordance with Knauf recommendations.
1 Maximum heights and fire resistance:
Maximum heights – calculated based on a limiting deflection of L/240 at 200 Pascals (0.2kN/m2).
The maximum heights related above is for fire resistance of system to meet project requirements of BS 476: Part 22: 1987 only.
For maximum heights in relation to meeting project requirements of BS EN 1364-1:2015, please consult Technical Services.
The fire resistance rating for system using Knauf Wallboard in this column can also support fire resistance rating of system when
replaced with Knauf Moisture Panel.
2 Period in minutes: inclusive of Integrity & Insulation
Note: Systems for fire resistance performances are for imperforate partitions, incorporating plasterboard with all outer joints taped and filled, in accordance with Knauf recommendations.

* Knauf Insulation Acoustic Roll in stud cavity
**Knauf Insulation Acoustic Roll in central cavity
† Bracing metal studs using Knauf Flat Fixing Plate or Knauf Fixing Channel at 1500mm. Note bracing using metal sections can reduce the sound reduction insulation by approximately 2dB (Rw) to overall system.
Note: Systems for both fire resistance and sound insulation performances are for imperforate partitions, incorporating plasterboard with all outer joints taped and filled, in accordance with Knauf recommendations.
