The following are standard Architectural Specifications for internal partition systems using PROMATECT®-H.
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 Both Sides / Non Loadbearing
Up to ‗‗‗‗‗‗‗‗‗‗(1) minutes
of fire rating, integrity and ‗‗‗‗‗‗‗‗‗‗(2)
minutes 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 R w
‗‗‗‗‗‗‗‗‗‗(3)
Supporting Structure
Care should be taken that any structural element that the partition system is supported from, e.g. concrete/brick wall, has equivalent fire
resistance of ‗‗‗‗‗‗‗‗‗‗(4) minutes.
Lining Boards
For 60 and 120 minutes of fire resistance, single layer of 9mm PROMATECT®-H
matrix engineered mineral boards as manufactured by Promat International (Asia Pacific) Ltd. For 240 minutes of fire resistance, two layers
of 9mm PROMATECT®-H matrix engineered mineral boards as manufactured by Promat
International (Asia Pacific) Ltd; or 360 minutes of fire resistance, two layers of 12mm PROMATECT®-H
matrix engineered mineral boards as manufactured by Promat International (Asia Pacific) Ltd.
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 60mm x M6 masonry anchors at 500mm centres.
Vertical steel studs are then friction fitted into the tracks at 610mm or 900mm maximum centres for boards to be installed vertically or horizontally.
Adequate clearance for vertical expansion will be allowed at the ceiling or top track. No clearance is necessary at the bottom track. See the following
tables for steel size and clearance at top track for given partition height.

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
Plain butt joints between machined edges of boards. (5)
Joints filled in preparation for painting. (6)
Joints filled and taped in preparation for decoration. (7)
Follow-on Trades
Surface of boards to be prepared for painting/plastering/tiling(8) in accordance with manufacturer’s recommendations.
NOTES:
(1) insert required fire rating and integrity durations.
(2) insert required insulation duration.
(3) insert acoustic values.
(4) insert required fire resistance level (not exceeding 360 minutes).
(5), (6), (7), (8) delete as appropriate.
