Framing

Twin (double) Knauf 70 'C' (0.55) at 600 mm centres to suit maximum height.
Head channel: Knauf 72 Deep Flange 'U' Channel (0.70) (70 mm deep flange).
Floor channel: Knauf 72 'U' Channel (0.55).

Insulation

2 x 25 mm Knauf Insulation Acoustic Roll (insulation installed between each stud frame).

Linings

1 x 15 mm Knauf Soundshield Plus on the inner layer of outer side double studs.
1 x 15 mm Knauf Performance Plus on the outer layer of outer side double studs.

Fasteners

Inner layer (each side): 25 mm Knauf Performance Plus screws.
Outer layer (each side): 45 mm Knauf Performance Plus screws.

Joint treatment

Horizontal joint: Knauf Flat Fixing Plate (to be applied behind outer layer plasterboard).

Finish

System must be taped and jointed using Knauf Joint Filler (Premium) or Knauf Joint Cement Premium and Knauf Joint Tape (Paper). Or alternative Knauf jointing compounds manufactured to EN 13963.
Knauf Wallboard Primer applied once taping and jointing completed.
Prior to where paint decoration is required. For preparation for decoration of where gypsum plaster skim is required, the outer layer of plasterboard joints is required to be taped and filled, using Knauf Joint Filler (Premium) and Knauf Joint Tape (Paper) meeting quality level 1 in accordance with Eurogypsum - Drywall Jointing & Finishing - Surface quality level classification.
For application where gypsum skim finish is required, the Knauf system is to be taped and filled using Knauf jointing compounds. When using Knauf Performance Plus, the applicator of gypsum skim finish is required to check if pre-treatment is required.

Deflection head

For deflection head allowance of up to -25 mm or ±12.5 mm, use 2 x 19 mm Knauf Coreboard fillets.

Manufacturer guidance

The fire resistance performance of the system is based on tested solutions using deflection head construction.

Fire resistance

EI 90 tested in accordance with BS EN 1364-1.

Sound insulation

65 dB (Rw) when tested to BS EN 10140-2.
60 dB (Rw + Ctr) when tested to BS EN 10140-2.

Duty rating (to BS 5234-2)

Severe Duty in accordance with BS 5234-2, clause 1.6.2 & 1.6.3 of Annex B & C.

System code

EN-IC-70-055-6-2x15-SSP-2x15-PP-2x25(229/90).

Guidance for specification option:

The maximum height stated (see Partition height) is for the fire resistance of the system to meet project requirements where EN compliance is required. The stated maximum height figure is the lower value between the cold state height, calculated structurally to a limiting deflection of L/240 @ 200 Pa and the fire state height, as outlined in accordance with EN 1364-1.

BS-IC-70-055-6-2x15-SSP-2x15-PP-2x25(229/90).

Guidance for specification option:

The maximum height stated (see Partition height) is for the fire resistance of the system to meet project requirements where BS compliance (BS 476-22), is required and is accepted by the client, designers and building control. The stated maximum height figure is based on the maximum cold state height, calculated structurally to a limiting deflection of L/240 @ 200 Pa.
