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 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. concrete/brick wall, has equivalent fire
resistance of ‗‗‗‗‗‗‗‗‗‗(3) minutes.
Lining Boards
FOR FRL OF -/60/60
One layer of 20mm and one layer of 15mm PROMATECT®-H matrix engineered mineral boards as
manufactured by Promat International (Asia Pacific) Ltd. Stagger joints by at least 300mm at the first layer and 200mm on the second layer. Standard board
dimensions 1220mm x 2440mm x 15mm or 20mm.
FOR FRL OF -/120/120
Two layers of 25mm PROMATECT®-H matrix engineered mineral boards as manufactured by
Promat International (Asia Pacific) Ltd. Stagger joints by at least 300mm at the first layer and 200mm on the second layer. Standard board
dimensions 1220mm x 2440mm x 25mm.
Fixing
FOR FRL OF -/60/60
Galvanised steel frame made of perimeter steel angle 40mm x 40mm x 1mm thick will be fastened to the wall/floor/ceiling with 40mm x M6 masonry
anchors at 500mm centres. First layer 20mm, fixed to perimeter angle using 30mm x No.8 screws at 200mm centres. Second layer 15mm, fixed to first
layer using 30mm x No.8 screws at 300mm centres around the perimeter and down the centre of each panel.
FOR FRL OF -/120/120
Galvanised steel frame made of perimeter steel angle 50mm x 50mm x 1mm thick will be fastened to the wall/floor/ceiling with 40mm x M6 masonry
anchors at 500mm centres. First layer 20mm, fixed to perimeter angle using 32mm x No.8 screws at 200mm centres. Second layer 15mm, fixed to first
layer using 45mm x No.8 screws at 300mm centres around the perimeter and down the centre of each panel. Third layer of board must be fastened to
the previous layers at 300mm centres using 65mm x No.8 screws.
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.
