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 120 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-70-055-6-2-15-SSP-2x25(229/120).

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-70-055-6-2-15-SSP-2x25(229/120).

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.
