The following are standard Architectural Specifications for internal partition systems using ®-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 Either Side / Non Loadbearing
Up to ‗‗‗‗‗‗‗‗‗‗(1) 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 R w
‗‗‗‗‗‗‗‗‗‗(2)
Supporting Structure
Care should be taken that any structural element that the partition system is supported from, e.g. steel stud or perimeter steel channel, has equivalent fire
resistance of ‗‗‗‗‗‗‗‗‗‗(3) minutes.
Lining Boards
Single layer of 6mm and 9mm PROMATECT®-H matrix engineered mineral boards as manufactured by Promat
International (Asia Pacific) Ltd. All joints to be coincident with steel framing or PROMATECT®-H
board strip. Standard board dimensions 1220mm x 2440mm.
Fixing
Softwood timber, 63mm deep x 50mm wide will be fixed to the perimeter of the opening where the partition system is to be installed using M6 expanding
anchors at 610mm centres.
Where the board are to be installed with their long edges vertical, the studs are located at 610mm maximum centres with cross noggings at 2440mm centres.
Where the boards are to be installed with their long edges horizontal, the studs are located at 610mm centres with cross noggings at 1220mm centres.
The PROMATECT®-H board are fixed to the framework using wire head nails of an appropriate
length, not less than 50mm, or No.8 screws of an appropriate length at nominal 300mm centres, a minimum of 12mm from the board edge.
Mineral wool will be contained within the cavity.
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. (4)
Joints filled in preparation for painting. (5)
Joints filled and taped in preparation for decoration. (6)
Follow-on Trades
Surface of boards to be prepared for painting/plastering/tiling(7) in accordance with manufacturer’s recommendations.
NOTES:
(1) insert required fire rating, integrity and insulation durations.
(2) insert acoustic values by reference to Marshall Day assessment.
(3) insert required fire resistance level (not exceeding
120 minutes).
(4), (5), (6), (7) delete as appropriate.
Perimeter gaps will be filled with fire resistant PROMASEAL® AN Acrylic Sealant.
