The following are standard Architectural Specifications for internal partition systems using PROMATECT®-100.
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 & Loadbearing
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 R w 39.
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 at
least fire resistance of 120 minutes.
Lining Boards
Single layer each side 20mm PROMATECT®-100 matrix engineered mineral boards as manufactured
by Promat International (Asia Pacific) Ltd. All joints to be coincident with steel framing. Standard board dimensions 1200mm x 2500mm x 20mm.
Fixing
Softwood timber, 90mm deep x 45mm wide will be fixed to the perimeter of the opening where the partition system is to be installed using M6 expanding
anchors at 600mm maximum centres.
Where the boards are to be installed with their long edges vertical, the studs are located at 600mm maximum centres with cross noggings at 1250mm centres.
Where the boards are to be installed with their long edges horizontal, the studs are located at 625mm centres with cross noggings at 600mm centres.
The PROMATECT®-100 boards are fixed to the framework using 100mm x No.8 woodscrews at
maximum 250mm centres, a minimum of 12mm from the board edge.
Where there is a requirement for loadbearing, the required size of the timber stud will be calculated by a qualified structural engineer who should allow
for the depth of the stud to be reduced by 50mm and the width by 10mm through charring.
Tests & Standards
Along with all material tests the complete system along with the framing is tested in accordance with the criteria of BS476: Part 22 and AS1530: Part 4.
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.
