SELECTION & SPECIFICATION
SYSTEM DESCRIPTION:
The Stramit Uniguard™ fire-resisting wall system is a superior fire-rated wall cladding solution combining a single layer of specialist Promina®60 board with profiled steel wall cladding. The system offers a choice of Stramit® Corrugated, Stramit® Monoclad or Stramit Longspan® wall cladding.
The Stramit Uniguard™ fire-resisting wall system provides a simple, economical means of constructing fire-resisting walls on site boundaries, saving on installation time and costs and providing superior external fire protection.
The Stramit Uniguard™ fire-resisting wall system can easily be substituted for systems using multiple fireboards or other firewall systems. Contact Stramit Building Products for further information.

- Versatile cladding options - Choice of Stramit® cladding profiles and rib orientation.
- Additional benefits - Acoustic insulation; uniform internal wall appearance; easily painted if required; all system components can be repaired or replaced if damaged by fire.
APPLICATIONS:
The combined strength and thermal protection properties of the Stramit Uniguard™ fire-resisting wall system make it the ideal boundary wall solution for industrial and commercial buildings. The simplicity of the system significantly reduces firewall building procedures and construction times.
The Promina®60 board is very durable and is resistant to fire, water and vermin.
The Stramit Uniguard™ fire-resisting wall system is to be used as an external wall system for single-storey Class 7b and 8 buildings of type C construction as defined in the Building Code of Australia (BSA2004).
The Stramit Uniguard™ fire-resisting wall system is suitable for use in both non-cyclonic and cyclonic regions. However be advised that in the event of a cyclone the system, as with all metal cladding systems may lose functionality and need replacement.
Note: The Stramit Uniguard™ fire-resisting wall system is intended only for commerical and industrial wall cladding applications. Do not use for any other purpose.
BCA FIRE RESISTANCE:
The Stramit Uniguard™ fire-resisting wall system provides a solution to the BCA requirements for external walls of buildings with floor area less than 2000m2 in Class 7b and Class 8 buildings (factories and warehouses) of type C construction. The system conforms to the BCA requirements for an 'alternative solution' (i.e. that can be demonstrated to be equivalent to the Deemed-to-Satisfy provisions). Testing has shown that the Stramit Uniguard™ system can meet the radiant heat flux exposure limits of Verification Method CV1;
Full details of the testing, BCA alternative solution verification and system constraints and limitations are provided in Warrington Fire Research Report No.40981B and subsequent appended opinions. Copies of the report are available from Stramit Building Products.
To meet BCA alternative solution requirements, it is essential that the details provided in this technical manual and the WFRA report are fully adhered to. It is recommended to submit the report to the relevant regulatory authorities to gain approval of the proposed alternative solution.
CARE IN USE:
To preserve the fire resistance qualities of the Promina®60 board, no holes should be created in the boards with nails, poster pins, etc.
MATERIALS:
The Promina®60 board is manufactured from calcium silicate, which looks and feels like conventional fibrous cement board.
Promina®60 boards are supplied in a standard size of 2400 x 1200mm with a thickness of 15mm and a mass of approximately 41kg per board.
Stramit® cladding is manufactured from hi-tensile G550 COLORBOND® or ZINCALUME® steel. In some locations COLORBOND® Ultra steel may be available by arrangement or galvanised steel available for special service environments. COLORBOND® and COLORBOND® Ultra steel is in accordance with AS2728-Category 3 and, for the substrate, AS1397. ZINCALUME® AZ150 and galvanised Z450 steel conform to AS1397. Spacing batterns are made from Z350 GALVASPAN® coated steel.
Stramit Building Products has a comprehensive range of COLORBOND® colours as standard. Refer to the COLORBOND® colour chart available from Stramit Building Products and refer to the nearest Stramit Building Products location for colour availability.
ADVERSE CONDITIONS:
Stramit Uniguard™ fire-resisting wall system is suitable for most non-coastal conditions; check external cladding technical manual for material selection.
COMPATIBILITY:
All building products should be checked for compatibility with adjacent materials. Check for direct contact between materials, as well as where water runs from one material to another.
COLORBOND® and ZINCALUME® cladding must not be in contact with concrete surface and must have a free drip edge.
Note: Direct contact between the Promina®60 board and the steel cladding must be avoided by the use of spacing batterns. See Design:Spans section for details.
TESTING:
The Stramit Uniguard™ fire-resisting wall system has been tested by Warrington Fire Research, Victoria. Copies of the report can be obtained from Stramit Building Products. Stramit cladding profiles have been comprehensively tested, including independent tests at the Cyclone Testing Station.
ARCHITECTURAL SPECIFICATION:
To ensure products of appropriate quality are used in construction of the firewall, use a specification similar to the following.
The walling shall be the Stramit Uniguard™ fire-resisting wall system where the external cladding is 0.42 or 0.48mm bmt Stramit® Corrugated, Monoclad® or Longspan® steel cladding. Design and installation must be in accordance with the manufacturer's published recommendations.
ACOUSTIC PROPERTIES:
While formal data is not currently available, the Stramit Uniguard™ system has intrinsic acoustic properties that aid noise attenuation.
WATER TOLERANCE:
The Promina®60 board is water tolerant; if it becomes wet it will not rot, deteriorate or lose strength once dry.
WATER ABSORPTION:
Absorption of water through the Promina®60 boards will not produce a detrimental effect to the boards themselves, however, items in contact with a damp board may react, cardboard boxes/fasteners/purlins and girts. The long performance of purlins and girts may be adversely affected if in contact with damp Promina®60 boards and any warranties previously granted by the supplier may be void. Hence, avoidance of water exposure to the boards is highly recommended.
