Manufacturer's standard.

Guidance for specification option:

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

Consult manufacturer for details.

System code

BS-ICB-70-055-6-2-15-SSP-2x25(229/90).

Guidance for specification option:

The maximum height stated under Partition height (see below) 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.

Partition height

Manufacturer guidance

Insert requirements, maximum 7000 mm.

See System code for further details.

Partition thickness

229 mm.
