1 PARTITIONING Systems Stud & Track An economical friction-fit system to assemble frames for strong, compact, lightweight non load-bearing partitions. The metal stud partitioning is ideal for use in domestic and commercial situations, for heights up to 12m and a wide range of partition thicknesses. When installing you should ensure that electrical cables that pass through floor or ceiling are protected by grommets when installing studs. For fast and accurate installation we recommend use of an electrical or battery operated screw gun. Note: electrical wires should be protected where passing through framework Track C Stud Snipped and folded to form header Light Switch Partition Brace Benefits Quick to erect, lightweight and clean Metal Stud is dimensionally accurate and will not twist or bow Range of stud widths 48mm, 50mm, 60mm, 70mm, 73mm, 92mm and 146mm to meet different performance requirements Services are easy to install Mineral wool can easily be installed to upgrade sound insulation Easy to cut to length using tin snips Frames easily fit together Door frames simply formed Sight line in Studs for lining up with plasterboard Stud and track formed from pre-galvanised mild steel to BS EN 10327:DX

5 PARTITIONING Systems Stud & Track High Performance Walls The non-load bearing High Performance Walls, constructed from plasterboard facings on metal studs, offer considerable advantages over traditional heavy masonry construction. Ceramic Tiling If ceramic tiles are being fixed to the finished wall, to prevent cracking of the tiles, stud centres must be reduced. For all systems the centres must be reduced to 400mm. This applies to C Studs, I Studs for Independent Wall Lining and Wall Liner. Please note: Tiles should only be fitted to double layer installations up to a maximum height of 3.6 metres. Staggered I Stud system Single frame system with Resilient Bar Track Resilient bars at 400mm or 600mm horizontal centres 25mm Acoustic Partition Roll I Studs at 300mm centres, staggered in track Twin frame system Track Typical floor detail Timber sole plate if required on uneven floors Partition brace On uneven floors use timber sole plate Pairs of C Studs, braced at mid-height with partition brace Acoustic Partition Roll cavity as required Timber sole plate if required on uneven floors Track 20

6 Stud & Track Cloaking Angle Acoustic Mastic Firestrip Sealant Rock Mineral Fibre Track Track Stud Stud Partition Brace Partition Brace Deflection head When partitions are erected to span the full height between floors, structural slabs or beams, accommodation for movement may be needed. The deflection heads shown will allow for movement up to 15mm and protect the partition from damage. These details have been both tested for fire resistance to BS 476 part 20 & 22 section 5. Fix plasterboard, allowing for a 15mm deflection at the partition head; do not screw fix the plasterboard to the studs or track above the Partition Brace. Insulation 25mm Acoustic Partition Roll insulation to be installed 300mm above and 300mm below metal socket box for full width between studs Wallboard fixed to back End cut and bent to fit stud centres Electrical Services - Acoustic Insulation To ensure they do not lie back to back, electrical sockets should be offset. Use Flat Strip or Partition Brace to support outlet boxes and seal around with acoustic sealant. Two layers, either side of 12.5mm standard plasterboard, will achieve 60 minutes of fire resistance. 21

7 PARTITIONING Systems Stud & Track Clamping Strip The galvanized clamping strip is used to cover joints when building partitions. A plastic or aluminium cover section clip can be used over the clamping strip to enhance the finished appearance. 3 Clamping Strip Standard Track mm Clamping Strip x 0.5mm mm Clamping Strip x 0.5mm mm Clamping Strip x 0.5mm mm Clamping Strip x 0.5mm Resilient Bar Resilient Bar x 0.5mm Resilient Bar Where the Resilient Bar is to be fixed to timber or metal studs, the following centres apply: Single layer boarding, fix Resilient Bar at 400mm centres Double layer boarding, fix Resilient Bar at 600mm centres Fix the initial Resilient Bar 50mm down from the ceiling and the last bar 50mm from the floor. Screw fix the Resilient Bars to the Studs using 25mm Drywall Self-Tapping Screws. Screw fix the wallboard to the Resilient Bar only, ensuring the screw does not touch the metal substrate. Ceiling Resilient Bar or or 600 Floor 22

8 SHAFT ENCASEMENT SYSTEM A high performance fire protection system to enclose shafts in high rise buildings. Our Shaft Encasement System allows installation to take place from the landing side only. This system is non load bearing and designed to fit between structural floors. Benefits Fast and simple to erect Cost effective Good Impact resistance and stiffness Lighter in weight than masonry High level of Fire Protection Allows any thickness of coreboard to be used Construction The Shaft Encasement System is installed from the non shaft side using I Stud framing. Fix long leg track to ceiling with suitable fixings spaced at 600mm maximum centres. Fix either standard or deep track along the floor with suitable fixings spaced at 600mm maximum centres. For 94mm and 148mm tracks we recommend two rows of staggered fixings at 600mm maximum centres. Coreboard nominally 595mm wide by either 19mm or 25mm thick is cut to length 25mm less than the overall height for standard track and 32mm for deep track. The Coreboard is located between the I Studs and secured using shaft encasement brackets spaced at 600mm maximum centres. The 25mm or 32mm gap is left at the top of the partition. Fire Resistant plasterboard packers 100mm deep are screw fixed to the coreboard at the head of the partition. It is important that the packers are tight against the head track and that the packers fill the full width of the track. Intumescent acoustic sealant must be used :- On all metal to structure surfaces On all metal to Coreboard surfaces Between plasterboard packers and coreboard at the head detail. Corner and Junction information is detailed separately. Fire Resistant plasterboard is fixed to the outside of the framework on the non shaft side of the partition. Single Layer Installations Fire Resistant plasterboard must be fixed at 300mm maximum centres to the metal framework with the appropriate length screw. Double Layer Installations Inner layer of Fire Resistant plasterboard can be fixed at 600mm maximum centres but outer layer must be fixed at 300mm maximum centres to the metal framework with the appropriate screw. The second layer of Fire Resistant plasterboard should be fixed with all joints staggered in relation to the inner layer. 23

11 PARTITIONING Systems ACOUSTIC STUD A cost-effective way to achieve improved acoustic performance in both domestic and commercial situations our Acoustic Stud has built in discontinuity which results in improved sound insulation. Acoustic Stud is designed to offer better sound insulation in the key speech frequency bands (250 to 1000 Hz) whilst maintaining structural strength and integrity. This enables slimmer partitions to be constructed, maximising floor space but still satisfying high acoustic requirements. Track Acoustic Stud Snipped and folded to form header Light Switch Partition Brace Benefits Extremely cost-effective Ideal for domestic and commercial use Reduced installation time Slimmer partitions maximise floor space Quieter living spaces Greater sound insulating performance Reduces the transfer of common noise 26

13 PARTITIONING Systems ACOUSTIC STUD Flanking Noise Flanking Transmission occurs when sound travels along elements shared by adjacent structures. Sound does not always travel straight through the building element. If the wall, floor or partition concerned has good sound-reducing capabilities, the sound will travel from A to B by the easiest route, often around the sides or over the top. You should bear in mind that flanking transmission can exceed direct transmission and damage the overall capabilities of the construction if flanking constructions are not correctly specified and constructed. To overcome this problem of flanking, any gaps in the installation must be filled with acoustic sealant on all edges and on both sides of the partition. Acoustic Mastic Track Acoustic Stud Construction Partitions built using Acoustic Stud are constructed in exactly the same way as those built using standard C Studs. All existing track sections can be utilised with Acoustic Studs and plasterboard-fixing centres will be exactly the same. Attention to detail is essential. Care must be taken in construction to ensure a soundproof structure performs to its maximum capability. As sound - like water, light or air will find the smallest crack and expose it as a weak point, your structure should be built as if it needs to be waterproofed. A single 25mm hole in an otherwise acoustically sound partition can reduce performance by up to an incredible 15 db. Although a 25mm hole should be visible a crack 1mm x 1m will not always be obvious and, if not treated with an acoustic sealant, will be detrimental to the structure. An acoustic construction is only as good as its weakest point. Acoustic Stud slot details

Staggered by half a board length, end joints must occur at the centre of the ceiling furring channel, leaving a gap of up to 3mm between ends of boards. The plasterboard is screw-fixed to the ceiling furring sections of the appropriate length. When using dual layer plasterboard, the first layer is fixed as shown. The second layer should be fixed with all joints staggered in relation to the first layer and screwed to the ceiling furring and edge channels, avoiding the screws used to fix the first layer.

20 MF SYSTEM MF Ceiling Installations MF Ceiling Installations are becoming increasingly common in the domestic market, primarily in houses and apartments. When they are installed in small rooms with low ceiling voids particularly where rooms have been well sealed and are airtight - in a minority of cases, movement of the metal components in the ceiling has caused unacceptable noise, typically when doors are opened and closed. To overcome this problem, in all domestic situations we recommend that the SMF5 Ceiling Furring Section is attached to the SMF7 Primary Channel using two self-drilling dry wall pan head screws per connection. Fire Resistance Our MF Ceiling System was tested at the Building Research Establishment to BS 476; part 23: The test was conducted under steel beams that supported pre-cast concrete slabs, using one layer of 12.5mm fire resistant wallboard. Minimum board mass must be 10.0 kg/m 2. The result achieved in test number is 75 minutes duration of effective protection. A further test has also been conducted to EN 136-2:2000 under a loaded timber floor using 2 layers of 12.5mm fire resistant wallboard with minimum board mass of 10kg/m 2. The result achieved in test no is 88 minutes duration of effective protection. Sound Insulation The MF Ceiling System offers excellent acoustic performance for airborne sound (Rw) and impact (Lnw) and will improve the sound insulation of both timber and concrete floors. Results are variable and mainly dependent on the depth of the ceiling void and the type of structure to which the system is fixed. Acoustic Hangers The important factors in maximising the improvements are cavity depth, insulation and acoustic hangers. Considerable sound improvement can be achieved by suspending an MF System using acoustic hangers - 35mm (232922) or 70mm (232929) which de-couple the floor from the ceiling. To join primary channels with nuts and bolts the minimum overlap is 150mm To join furring sections overlap by at least 150mm and either crimp or screw fix both sides in two places Partition Head Primary Channel SMF7 Ceiling Channel SMF5 Track 35

21 CEILING SYSTEMS CEILING LINING SYSTEM Insulation if required Concrete Slab Perimeter Channel Ceiling Liner Bracket Concrete Floor Slabs Often used in commercial and domestic situations and suited to both new-build and refurbishment projects, the Ceiling Lining System is suitable for most internal applications. It can be used under timber or concrete flooring with any proprietary Gypsum plasterboard and cavities can contain an insulation material. Construction Fix perimeter channel at 600mm centres maximum and - depending on the length of plasterboard being used - support the Ceiling Liner at centres of between 400mm and 600mm. Position fixing brackets - 75mm leg or 125mm leg - to timber joists or concrete. For large areas of ceiling use Ceiling Liner connector to join the Ceiling Liner together. Fix plasterboards with long edges at right angles to Ceiling Liner and fix to framing with drywall screws at 230mm maximum centres and, at perimeter ends of plasterboard, at 150mm maximum centres. Ensure drywall screws penetrate the section by a minimum of 10mm and, if a dual layer system is used, that all joints in the second board layer are staggered in relation to those of the first layer. Joists may be uneven in new buildings and such problems are commonly encountered in renovation work, particularly in older properties. To compensate for any unevenness, the Ceiling Lining System uses adjustable metal brackets that make it much easier to achieve a true flat surface. The system offers improved sound and fire performance and avoids the risk of cracking due to boards being directly fixed to timbers which may be subject to movement. The Ceiling Lining System provides an extremely convenient means of creating a cavity to accommodate services, without potentially weakening the overall structure by drilling joists. 36

23 CEILING SYSTEMS CEILING LINING SYSTEM UNDER TIMBER Fire Resistance The latest test carried out at the Warrington Fire Research Establishment was tested to the new European Standard - BS EN : Fire Resistance Tests for Load Bearing Elements/part 2:Floors and Ceilings. This test is more stringent than the previous British Standard. The test was conducted under a wooden floor with weights loaded above, using one layer of 12.5mm fire resistant wallboard. Minimum board mass must be 10.0 kg/m 2. Result achieved from test number WARRES is 60 minutes load bearing capacity, integrity and insulation. Sound Insulation The Ceiling Lining System gives good acoustic performance for airborne sound (Rw) and impact (Lnw). This system will improve the sound insulation of both timber and concrete floors. Results are variable mainly dependant on the depth of the ceiling void and the type of structure to which the system is fixed. The important factors in maximising the improvements are:- 1 Cavity depth 1 Cavity insulation 1 Acoustic hangers Acoustic Hangers By suspending a Ceiling Lining System using acoustic hangers which de-couple the floor from the ceiling, considerable sound improvement can be achieved.

29 CEILING SYSTEMS RESILIENT BAR UNDER TIMBER The sound insulation performance of some ceiling systems is dependent upon the attachment of a Resilient Bar to the underside of the joists and perimeter noggins on all four sides of a room. The Resilient Bar is fixed at right angles to the joists at 450mm maximum centres for single or double applications. When 2400mm board is being used the Resilient Bar will need to reduce to 400mm centres. Bars are jointed by overlapping directly over joists with a minimum overlap of 200mm. Plasterboards are fixed with long edges at right angles to Resilient Bars at 230mm centres using Drywall self-tapping screws which should penetrate the Resilient Bar by a minimum of 10mm. Timber Joists Resilient Bar Plasterboard Recommendations for maximum loadings for Resilient Bars Centres Uniformed distributed (mm) load (kg/m 2 ) mm centres for single or double board applications (max) Resilient Bar Resilient Bar x 0.5mm The Resilient Bar is designed to offer improved acoustic insulation when constructing a conventional ceiling under timber joists. Mineral wool insulation can be included in the floor cavity to improve acoustic performance. To ensure maximum sound insulation performance, screws fixing the plasterboard must not be in contact with the joists. When installing a dual layer of boards, all joints in the second layer must be staggered in relation to those of the first layer. 45 Resilient Bar 17 The following were tested as floor applications under timber beams 235mm x 50mm spaced at 450mm centres with 15mm OSB fixed to the top of the joists. Each ceiling was boarded with an inner layer of 19mm standard plasterboard (plank) and an outer layer of 12.5mm sound resistant wallboard. 100mm Acoustic Joist Roll was infilled into the joist cavities.

31 CEILING SYSTEMS FLOATING FLOORS timber flooring Acoustic Floating Floor 19mm plank resilient raft tape floor zed FF mm Acoustic Joist Roll 1 layer of 12.5mm sound resistant plasterboard resilient bar at 450mm maximum centres Ceiling: 1 layer of 19mm plank Our floating floor system offers excellent acoustic improvement for both airborne and impact sound transfer. This system is ideal for residential conversions and refurbishments of older properties to upgrade existing timber floors. It can also be used to improve sound insulation from upper floors in new build projects. Benefits 1 Minimal increase in floor depth 1 Floor floats independent of original structure 1 Ideal for conversion work & refurbishment 1 Fast and simple to fit 1 Suitable for any size timber joist 1 Cost effective 1 Improvement of sound insulation Construction Flooring Fit self adhesive resilient tape along the length of each joist. On top of the resilient raft tape place a floor zed section each side of the joist with the large flange on top of the beam. For smaller joists it may be necessary to overlap the flanges of the floor zed section. On larger joists there can be a gap between the sections. To help installation it may help to secure floor joist sections into place by fixing with an occasional temporary screw. 19mm plank is cut neat (not tight) to fit between the floor zed sections. The next board should be butted tightly to the previous board. The timber flooring is then laid across the top at 90º to the floor zed sections and screw fixed through the plank and into the bottom flange of the floor zed section using suitable screws. It is important to ensure that any temporary screws are removed from the floor zed sections before fitting the timber flooring and that no fixings are allowed to connect the floor zed section to the timber joist through the timber flooring. A 5mm clearance gap must be left at perimeter walls which must be fully filled with acoustic mastic. By following this procedure a completely free floating floor has been created. 46

32 FLOATING FLOORS Ceilings Resilient bar RB565 is fixed at right angles to the joists at maximum 450mm centres for single or double board applications. Bars are joined by butting together under the timber joist. Plasterboards are fixed with long edges at right angles to resilient bars at 230mm centres using drywall self tapping screws which should penetrate the resilient bar by a minimum of 10mm. To ensure maximum sound insulation performance, screws fixing the plasterboard must not be in contact with the joists. When installing double layers of plasterboard, all joints in the second layer must be staggered in relation to those of the first layer. Small joist Large joist Premier joist The addition of glass mineral wool insulation within the floor cavity will improve the acoustic performance.

35 WALL Lining Systems WALL LINER Construction Establish the depth of the cavity and fix wall liner track at 600mm centres to the floor and ceiling with the shallow leg towards the wall. At every 600mm centre, fix brackets to the wall. Only one bracket is required for heights up to 2.4 metres, though brackets must not exceed 800mm centres on walls more than 2.4 metres high. Cut Wall Liner Section to length and slot it into the top and bottom track. Adjust brackets to suit board tolerances before final tightening, then fix with self-drilling screws to the side of the Wall Liner Section. If a bracket protrudes beyond the face, simply bend the overhang over. Fix 1200mm wide plasterboard at suitable centres using 25mm drywall screws. Fixtures Heavy or medium fixtures - such as heating units, radiators, cupboards and washbasins - must be fixed with proprietary anchors which are long enough to pass through the cavity and penetrate the masonry background to a suitable depth.
