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 Board Side / Non Loadbearing
Up to 120/240* minutes of fire rating, integrity only in accordance with the criteria of BS476: Part 22: 1987.
Acoustic Performance
The partition system shall have a Weighted Sound Reduction Index of R w 27.
Supporting Structure
Care should be taken that any structural element to which the partition system is affixed, e.g. structural steel or concrete/brick wall, has
equivalent fire resistance of 120/240* minutes.
Lining Boards
Single layer of 9mm PROMATECT®-H* matrix engineered mineral boards as manufactured
by Promat International (Asia Pacific) Ltd. All joints to be coincident with steel framing sections. Standard board dimensions 1220mm x 2440mm x 9mm.
Double layer of 9mm PROMATECT®-H* matrix engineered mineral boards as manufactured
by Promat International (Asia Pacific) Ltd. Stagger joints by at least 300mm at both layers. 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 or horizontally.

at nominal 200mm centres, 25mm long for first layer board and 35mm long for second layer.
*For heights above 10000mm, back-to-back channels are fastened together with minimum M6 steel bolts and nuts at maximum 400mm centres.
Tests & Standards
The complete system along with the material and framing and approval for a performance is tested in accordance with the relevant criteria of 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. (1)
Joints filled in preparation for painting. (2)
Joints filled and taped in preparation for decoration. (3)
Follow-on Trades
Surface of boards to be prepared for painting/plastering/tiling(4) in accordance with manufacturer’s recommendations.
NOTES:
(1), (2), (3), (4), * delete as appropriate.
Perimeter gaps will be filled with fire resistant PROMASEAL® AN Acrylic Sealant.
