fermacell Dry lining

BS 5234-2 classifies the robustness or impact require-ment of partitions as Light Duty, Medium Duty, Heavy Duty or Severe Duty. "Standard specifications, layouts and dimensions: Partitions in schools" (SSLD – published by the Department for Education) requires that all partitions are constructed to the Severe Duty standard. All fermacell solutions for schools meet this requirement, and our confidence in fermacell's ability to cope with a busy school environment leads us to offer a 20-year warranty against impact damage.

The SSLD gives a comparison between plasterboard and gypsum fibreboard (fermacell) that demonstrates the superiority in load holding that fermacell can bring to a partition. This eliminates costly plywood pattressing and allows for completely different room layouts in the future as there is no need to consider which walls have had it installed.

Effectively all the walls with fermacell have been prepared to take substantial loads, thus future-proofing whatever room layout is required. Examples of fixings and their maximum load-holding strengths are shown below – all into a single layer of 12.5 mm fermacell without plywood pattressing.

fermacell systems – impact resistance you can rely on.

fermacell delivers high levels of acoustic, fire and impact performance and removes the need for many different board types associated with traditional drywall systems. All fermacell systems for education use a 75 mm C stud as standard, thus further standardising the components required. This makes it almost impossible for costly mistakes to occur on-site.

Specifying fermacell is even easier. All levels of acoustic and fire performance can be achieved with just six fermacell systems, compared to the dozens for conventional drywall systems. In addition, all fermacell education systems are rated Severe Duty, so there is no possibility of an under-strength partition being installed.

With just SIX partition systems, specifying and using fermacell solutions couldn't be easier.

Duty rating performance criteria for fermacell walls

(1) Maximum stud centres = 50 × board thickness. Note: where fixings are less than 500 mm apart, reduce the load per fixing by 50%. If a stud support separates the fixings, then use the full load-holding strength shown above.

(2) Safety factor: 2 (static load with relative humidity of up to 85%). (3) Depth of cupboard or shelves: max. 350 mm.(4) Standard toggle bolt with > 4 mm dia. screw. (The toggle bolt manufacturer’s

instruction should be followed.)

fermacell steel stud partitions have been tested to BS 5234-2 and are rated Severe Duty*

Specifying duty rating with fermacell solutions is a simple process. In addition, fermacell has carried out a vast range of testing, which includes soft- and hard-body impact testing. Severe Duty can be achieved by using a single 75 mm DIN standard stud with a single layer of 12.5 mm fermacell on one side.

* Up to 5 metres – contact the Technical department for further details.

Sound insulation

Building Bulletin 93 (BB93) provides performance standards in terms of the level difference (DnT(Tmf,max),w) for the attenua-tion of airborne sound transmission between adjoining rooms.

The level differences must be determined in both directions as one direction may have more stringent performance criteria. These values can simply be found by using the table on the following page and tracing across to where the two room types coincide. The minimum weighted sound level difference between rooms is quoted in terms of DnT(Tmf,max),w. However, partition performances are based on laboratory airborne sound insulation data measured in terms of sound reduction index Rw. The following procedure applies a correction factor to take this difference into account, and can be used to select an appropriate partition specification.

Determine the minimum BB93 weighted standardised sound level difference between rooms in each direction and the associated reverberation time (Tmf,max) from the table on pages 6 and 7.

Estimate the required weighted sound reduction index (Rw est)

using the following formula:

Rw est = DnT(Tmf,max),w + 10 log (S × Tmf,max)

V + 8 dB

Where: S = surface area of the separating element V = volume of the receiving room Tmf,max = maximum value of the reverberation time Tmf

To account for less favourable mounting conditions and flanking noise transmission, a correction factor X is applied to the estimated value above. BB93 recommends an adjustment of 5 dB. Based on fermacell’s experience across Europe, however, we would suggest an adjustment of between 5 and 7 dB, depending on flanking details. If in doubt, an acoustic consultant should be appointed to advise in this respect. Therefore, the weighted sound reduction index Rw that should be used to select the partition based on laboratory test data is:

Rw = Rw est + X dB or Rw = Rw est + (5 or 7) dB

The “reaction to fire” regulations award the highest performance material of limited combustibility with a Class 0 or Class 1 surface spread of flame rating, which fermacell provides. In addition, fermacell is Euroclass A2-certified. However, it is the construction of the partition as a whole that matters and, in schools, both Building Regulations (Part B) and Building Bulletin 100 (BB100) are used as guides. The requirements are set for 30, 60, 90 or 120 minutes.

In order to demonstrate compliance, fermacell partitions meet the requirements of BS 476 and/or the European standard of BS EN 1364.

Sports halls:

Impact protection using

fermacell systems

The superior performance of fermacell allows it to be used as a cladding for walls in sports halls where impact protection as well as soundproofing and fire protection are paramount.

RequirementsWall constructions in sports halls must not only meet technical fireproofing and sound insulation requirements, but also provide impact resistance from balls and bodies. The lining must be able to withstand mechanical impact stresses without sustaining permanent damage.

The solutionFor wall constructions in sports halls, a double-layer lining using 12.5 mm fermacell enables higher levels of protection against hard and soft ball impact (e.g. behind a hockey or a foot-ball goal) as well as withstanding the solid impact of the players themselves. Simple ball impact protection for ceilings can easily be achieved.

Installation

Wall constructionsFor wall linings, two layers are required:

Sub structure■ Stud support centres – DIN steel studs (75 mm × 50 mm fixing face × 0.6 mm gauge steel studs) max. 300 mm centres.

First (inner) layer ■ 12.5 mm square-edged fermacell Gypsum Fibreboard.■ Board fixings – fermacell Screws (3.9 × 30 mm, fixing centres ≤ 400 mm), board jointing – dry butt joint

Second layer■ 12.5 mm thick square-edged fermacell Gypsum Fibreboards through the first layer into the substructure; ■ Board fixings – fermacell Screws (3.9 × 45 mm, fixing centres ≤ 200 mm), joints to be staggered between the two layers of fermacell by ≥ 200 mm■ Board jointing – fermacell Jointstik adhesive.

Separate wall and ceiling connectionsWhere fermacell abuts other materials such as plaster, exposed concrete, masonry, steel or wood, care must be taken as each has its own differential movement rate (expansion and contraction with environmental changes).

1) Junctions with elastic/flexible sealing material.The back of the profile being fixed to the wall must be fitted with an isolation strip (for fire and acoustic purposes). Any gaps can then be filled with a flexible sealant that has a permanent expansion of at least 20%.The gap left should normally be a minimum of 3 to 5 mm.

(2) Junctions using fermacell Joint Filler.Fit studwork and isolation material. When fixing the boards to the studs, leave a 5 to 7 mm gap and fill with fermacell Joint Filler.

For fire resistance requirements:Use a fire-rated isolation strip. Rockwool type material should be no more than 5 mm thick(1) Junctions with sealing material – fire-rated as required.(2) Junctions with fermacell Joint Filler.

Deflection head details Deflection head details are required where deflection is expected to exceed 10 mm.There are three sections which must have the same minimum distance available for the deflection head to work. These are:1. The distance from the top of the board to the soffit.2. The distance from the top of the stud to the head track.3. The distance from the bottom of the head track leg to the first fixing into the stud.A = deflection ≤ 25 mm using timber at the head fermacell partition, single-layer boarding. F-30 B/F 60-B, deflection head detail. Minimum overlap of board to timber = 25 mm.

Deflection head detail can be constructed using fermacell strips or timber sections. The total thickness of the fermacell strips or timber section must correspond to the deflection specified/expected, plus the overlap for the boarding.Minimum timber widths for F30 and F60 solutions are:F30 = minimum 50 mm wide timberF60 = minimum 70 mm wide timberFor F90 partitions, use minimum 50 mm wide fermacell strips.For F120 solution please contact the fermacell Technical department.For wall heights above 5 000 mm, the deflection head detail must be mechanically stabilised with appropriate extra measures, such as support brackets. A = deflection in ≤ 20 mm maximum for F90 and F120 partition.

Movement control joints are required in fermacell steel stud partitions. They should also be placed in linings or partitions to mirror any structural movement joints in the main shell of the building.

The spacing of movement control joints depends on the jointing method used. When using the adhesive Jointstik method, they can be placed at maximum 10 m intervals. When using the Joint Filler method or tapered-edge board method, they can be placed at maximum intervals of 8 m.

Where required, movement joints and end wall movement joints can be used together to provide the simplest solution.

Doors and windows

Door frame installation methodsThere are many different methods of fixing that can be used for securing door frames to/in fermacell partitions and fire walls. These depend on the room height (wall height), door width, weight of the door leaf, including door furniture, etc.

Please see the fermacell datasheet regarding door frame reinforcement.The guidelines for different door support types are based on the following door weights as a guide. Double door and leaf and a half doors will always require additional support.

≤ 25 kg doors – timber inserts are required for up to 2.5 m of the partition height.

25–60 kg doors – timber inserts are required for at least 3 m An L bracket is required at the head of the timber support. 60 kg + doors – steel door reinforcement kit and timber insert. When boarding around doors and openings it is imperative that joints do not run vertically from corners. The boards should be cut to allow joints to sit above the door head and offset from the edge of the door/opening by > 200 mm. Installation methods for glazingWhere glazing details are to be installed in fermacell walls, additional support will be required.

The screw-retention capabilities offermacell allows most fixtures to be fitted directly to the board (see table on page 4).

Board fittingfermacell boards come in square- or tapered-edge variants. Square-edged boards are jointed using the fermacell Joinstik adhesive and tapered-edge boards are jointed using tape and filler.

Surface finishWith fermacell FST, a skim type finish can be achieved without specialist trades and be ready to decorate within 45 minutes.

WallpaperingWith the exception of vinyl wallpapers, all types of paper can be applied to fermacell using standard trade pastes, without priming the surface. When using vinyl papers, it is recommended that wallpaper manufacturer s advice be followed.

fermacell boards are fitted and finished slightly differently to traditional plasterboard,

which speeds up the installation time by reducing drying out times and provides a

user-friendlier finishing system with our fine surface treatment (FST).
