The following are standard Architectural Specifications for internal partition systems using PROMINA®-60.
The designer must determine the suitability of the design to the application and requirements before undertaking or constructing any works relating to
the specifications and where in doubt should obtain the advice of a suitably qualified engineer.
Fire Attack From Either Side / Non Loadbearing
Up to 120 minutes of fire rating, integrity and insulation in accordance with the criteria of BS476: Part 22: 1987 and AS1530: Part 4: 2005.
Acoustic Performance
The partition system shall have a Weighted Sound Reduction Index of at least R w 45.
Supporting Structure
Care should be taken that any structural element that the partition system is supported from, e.g. concrete/brick wall or slab, has
at least an equivalent fire resistance.
Lining Boards
Single layer of 15mm gypsum wall board.
Single layer of 9mm PROMINA®-60 matrix engineered mineral boards as manufactured by Promat
International (Asia Pacific) Ltd. All joints to be coincident with PROMATECT®-H board strip.
Standard board dimensions 1220mm x 2440mm x 9mm.
Fixing
Galvanised steel frame made of ceiling and floor tracks will be secured to the floor, ceiling and walls with 40mm x M6 masonry anchors at 500mm centres.
Vertical steel studs are then friction fitted into the tracks at 610mm maximum centres for boards to be installed vertically.

Tests & Standards
The complete system along with the material and framing is tested in accordance with BS476: Part 22: 1987. The partition system should meet the
requirements as specified under Clause 5.
Jointing
