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 at least R w
‗‗‗‗‗‗‗‗‗‗(2).
Supporting Structure
Care should be taken that any structural element by which the partition system is supported, e.g. steel structure, concrete/brick wall or slab, has at
least equivalent fire resistance of ‗‗‗‗‗‗‗‗‗‗(3) minutes.
Lining Boards
Single layer of 9mm 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 sheeting rails will be bolted horizontally at maximum 1800mm centres. Fix galvanised steel top hat sections vertically at 610mm centres.
External cladding will be fixed at the external part, after PROMATECT®-H boards are fixed.
9mm thick of PROMATECT®-H boards will be fixed to the steel framing at the internal and
external faces. Cover strips to back all horizontal joints between boards and to separate vertical top hats and sheeting rail.
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.
