Description

The KOROK® 51 mm Wall System and KOROK® KIT Wall Systems are used to construct fire and acoustically rated walls and partitions within building envelopes.

The KOROK® panels are made from aerated concrete encased in profiled galvanised steel sheet formwork and are non-loadbearing, whilst the structural elements of the wall system can be loadbearing.

Scope

1. The KOROK® 51 mm Wall System and KOROK® 51 mm Wall System and KOROK® KIT Wall Systems have been appraised for use as non-loadbearing fire and acoustically rated internally located walls and partitions for all buildings of all importance levels as defined by AS/NZS 1170.

2. The KOROK® KIT Wall System panels are installed in vertical orientation. For the intertenancy wall systems the panels are fixed to the timber or steel framing with aluminium brackets at the panel face or joints at maximum 3.5 m intervals vertically and 0.6 m intervals horizontally. The total height of the KOROK® panels in a single wall must not exceed 14 m.

3. For the KOROK® 51 mm plain wall panel the maximum unsupported span for the panels between structural supports is 8 m. The overall height or length of a KOROK® 51 mm plain wall will be determined by the structural support. When used as part of a fire rated system, the maximum unsupported span of the KOROK® panels is 6 m for vertical orientation and 4 m for horizontal orientation. Greater spans are subject to specific engineering design and/or fire engineering assessment and are outside the scope of this Appraisal.

4 The KOROK® 51 mm Wall System and KOROK® KIT Wall Systems have been appraised for use in intertenancy walls when used with the wall framing, wall insulation and wall lining specified in this Appraisal.
