7 CI/SfB (59) X (K2) pril 2009 (replaces September 2008 issue) pplication type Construction type Fire Penetration Void Fillers blative Coated Batt Firestop solution for large voids in walls and floors s part of the comprehensive FirePro range of fire protection products, the Rockwool blative Coated Batt is used to provide fire and acoustic barriers for voids created by the passage of services in both dry wall systems and masonry walls and floors. Such services include pipes made from steel, copper, PVC, BS and HDPE together with sheathed cables supported on both trays and ladders. The Batts can also be used to from a blank seal, up to 1200mm x 600mm, in such wall and floor voids. In response to this growing and increasingly important market, Rockwool has re-designed and tested the product to the dedicated fire resistance standard for penetration seals - pren Due to its specific nature, this document is intended to supersede the traditional BS 476: Parts 20 and 22 previously used for fire seal testing in the UK construction market. The tests have proved the capability of a single 60mm Batt to provide up to 4 hours fire resistance integrity and up to 2 hours insulation when used with all of the services listed above and also as a blank seal. Even for extreme requirements, where 4 hours integrity and insulation are required to maintain the performance of a masonry wall, a solution can also be accomplished with a double Batt solution. General benefits: Excellent fire resistance from single thickness Batt Standard size: 1200 x 600 x60mm Suitable for sealing large wall and floor voids containing most commonly used services Can be used as a blank seal Tested for use in masonry and dry wall constructions Lightweight and simple installation Maintenance free 180kg density base material provides additional benefits of a smoke and acoustic seal Rockwool supports FIRS accredited installers The following NBS Plus clauses include blative Coated Batt : P12-335, P12-345, P

8 Description, performance and properties The Batt is not intended for maintaining the loadbearing capability of the floor and suitable precautions, such as an adequate safety rail and signage, should be adopted to prevent access and potential accidents. SFETY RIL ROCKWOOL INSULTED FIRE SLEEVE ROCKWOOL COTED BTT CONLIT BNDGE CBLE LDDER ROCKWOOL FIRE TUBE Installation Health and safety FirePro Coated Batts are manufactured by spraying specially produced, high density Rockwool insulation with an additional fire protection ablative coating. To install, the Batts are simply cut and friction fitted between the services and the edges of the wall or floor void to completely seal the void. Where but joints are required between cut sections of adjacent Batts, the fire rated coating is applied to both mating edges in order to form a fire tight bond between the individual pieces of insulation. ll joints, including those around the perimeter of the Batt, are then ROCKWOOL COTED BTT pointed with FirePro coustic Intumescent Sealant to complete the seal. It must be noted that plastic pipes (PVC, BS and HDPE etc.) must be sleeved with FirePro Insulated Fire Sleeves at the point at which they pass through the blative Coated Batt. Similarly to achieve fire resistance insulation (I) with metal pipes such as steel and copper, the pipes must be fully insulated along their length and, for a minimum distance of 500mm either side of the coated batt, this insulation must be Rockwool FirePro FireTube. The joint between the Batt and Fire Sleeve or Fire Tube must be pointed with the FirePro Sealant. Load-Bearing seals FirePro blative Coated Batts are not intended for use as load-bearing seals. Where a load-bearing seal is required, Rockwool FireStop Compound should be considered. Fire performance Current HSE CHIP Regulations and EU directive 97/69/EC confirm the safety of Rockwool mineral wool; Rockwool fibres are not classified as a possible human carcinogen. The maximum exposure limit for mineral wool is 5mg/m 3, 8 hour time-weighted average.

10 Estimating quantities The chart below indicates the usage of ccess Floor FireStop Slabs of dimension 1200 x 1000mm. ccurate site cutting practices are assumed. Cavity Size (mm) Linear metres per slab (LM) F 30 Slab LM per pack F 60 Slab LM per pack NOTE: Fixing brackets are NOT required for voids up to and including 400mm. For voids greater than 400mm, F 60 should be used for both 30 and 60 minute fire resistance requirements together with brackets. (See Sitework) Sitework ccess Floor FireStops are designed for cutting on site with a sharp knife or saw and a straight edge. The access floor cavity to be firestopped should be measured and the ccess Floor FireStop cut to suit the dimension. Pieces cut to required depth are also available. Cutting should be along the 1000mm xis only. The fixing sequence is as follows: 1. Cut the ccess Floor FireStops allowing an additional 7 10mm for compression when fitted. 2. The product should be fitted vertically into the void, tightly butted and aligned to the adjacent ccess Floor FireStop. 3. The vertical joints between individual F 30 or F 60 ccess Floor FireStops should be sealed with self adhesive class O aluminium foil tape. If required, this can also be used to totally enclose the unfaced surfaces. VOIDS UP TO 400mm F 30 and F 60 ccess Floor FireStops do not require any fixing to the access floor or the structural floor. VOIDS FROM 401 TO 600mm For voids above 400mm, F 60 ccess Floor FireStops should be used for both 30 and 60 minute fire resistance requirements. Rockwool SP/L fixing brackets are required for additional stability of the assembly. The fixing brackets are bent 90 o to form an L shape, the leg with the angled point being approximately 300mm long. This leg is then impaled centrally into the base of the fire stop, with alternate brackets protruding either side. The brackets are required at a maximum centre frequency of 500mm and each bracket should be mechanically fixed to the structural floor using steel fixings. Service Penetrations CBLE TRYS/TRUNKING Services must be supported on either side of the ccess Floor FireStops at points of penetration. If gaps are created by inaccurate cutting offcuts of ccess Floor FireStop must be inserted. This material must be tightly compressed around the penetration. For protection of the services themselves, please refer to the Rockwool FirePro range of solutions. Reference should be made to the requirements of Section 10 of pproved Document B of the Building Regulations which may require the use of additional sleeving to the trunking or trays. Reference should be made to the requirements of the current IEE Wiring Regulations governing the rating of cables enclosed within insulation.

21 BeamClad glued noggin or stud welded pin glued joint board systems The following two systems are well established having been used for many years. The application of FirePro Glue (previously Conlit glue) enhances the fire performance over the Dry Joint Systems for the 2, 3 and 4 hour periods. The Glue Joint Systems are capable of providing up to 4 hours fire protection. Fixing boards to noggins Wherever three or four-sided protection is required, fixing to noggins is a practical option. No power supply is required. Fixing boards with stud welded pins Situations will always occur where noggins do not afford a practical choice, e.g. for two-sided box constructions or diverse perimeter bracketing. 3-sided box noggins to project slightly beyond flange Fixing pattern Min. recommended thickness 50mm If greater than 500mm Min. 120mm width Full depth noggin or Tee-noggin for web depths greater than 500mm Stud welded pins allow the installer a simple, tested alternative to noggins. min. 120mm wide noggins Installation sequence (noggin fix) 1 Fixing noggins Cut 120mm wide noggins to suit web depth, using same thickness material as the cover protection. For web depths of 500mm and above use either solid noggins or T shaped noggins. For stability purposes, it is recommended that the face of the T noggin is made from the same thickness as the cover board but the thickness of the return into the web should be at least 50mm. These are then glued into position at 1000mm centres. 2 Fixing boards a pply FirePro Glue liberally to face of noggins. Quickly apply vertical boards and secure with nails long enough to pierce full thickness of noggins before FirePro glue forms a hardened surface. b pply glue continuously and liberally to all board interfaces.

Where practical, stagger the joints between each layer. For welded pin applications, each layer should be retained using seperate non-return washer, i.e. one washer per layer. For glued noggin applications, attach the first layer to the noggins as previously detailed, then apply a 120mm wide band of glue to the outside face of the first layer at locations corresponding to the noggins. pply the outer layer of BeamClad, supporting the boards until the glue sets by using nails of sufficient length to penetrate completely through the noggins Fire resistance period (hours) Fire resistance period (hours) Fire resistance period (hours) BeamClad thicknesses to be read with Tables 7, 8 & 9 The following key provides the required minimum thicknesses of BeamClad for the Section Factors given in the tables. The boards can be applied in either one or two layers. General notes Board jointing Butted corner joints Butted corner joints are made with square edge boards and depending on the system emplyed, use either a dry joint with pigtail screws at 150mm or 200mm centres, or FirePro Glue and nails at 400mm centres. Butted corner joints (with pigtail screws) xial joints ll axial joints are made with square butt edges, without nails. Glue is only required for glued board systems. Joints must be tightly butted. For foil faced products, joints can be finished with Class O foil tape. Noggins BeamClad boards can be fixed to noggins, cut from BeamClad offcuts. The edges of the noggins are glued where they contact the steelwork. Once the noggins have set firmly, the cover boards are fixed in position with either pigtail screws or FirePro Glue and nails. The thickness of the noggin is to be the same as that of the cover board used. 16 Dry joint Firepro glue Pigtail screws at 150 or 200mm nominal centres (see system options, page 1) Screw length = minimum 2 thickness of cover board - 5mm = 25mm B = 30mm C = 35mm D = 40mm Welded steel pins Boards are secured to stud welded pins with non-return washers. Glue E = 45mm F = 50mm G = 60mm H = 70mm FirePro Glue (previously Conlit glue) is required between all board-toboard and board-to-noggin joints for glued systems, but only between noggin-to- steel joints for dry systems. pplying FirePro Glue on the external face of joints is bad practice. Whatever noggin system is employed, the glue between noggin and steel must be allowed to set hard before cover boards are applied to the noggins. This will normally take about 4 hours at 20 C ambient temperature. FirePro Glue is supplied pre-mixed in 17 kg tubs. I = 80mm J = 90mm K = 100mm L = 110mm Coverage rate will depend on the linear length of the joints, width of joint (board thickness) and joint depth. ssuming total, effective useage of the glue on site, the following table provides an approximate weight (kg) of glue per linear metre of joint, based on a glue depth of 1mm. BeamClad thickness (mm) Square butt joint 45 mitre joint In practice, a degree of wastage would be expected and as such, it would be prudent to make an allowance for this when placing an order. s a very approximate guide, the coverage rate of a 17kg tub of FirePro glue would be 35m 2 of applied board

24 General notes for systems a Ensure steel is free from grease, dust or loose particles where noggins are to be glued, pins welded or clips applied. b Dry off steelwork where large water droplets are present. Steel damp to the touch is acceptable. c Ensure that all noggins have the correct friction fit. void excessive interference that may cause noggins to bend. d Fix additional noggins (if required) at beam ends, beam-to-beam joints and large penetrations. For stud welded pin and clip systems it may be necessary to introduce soldier noggins into webs behind board to board joints to increase stability of the system on steelwork with large web depths. e For glued system options ensure that all noggin-to-beam, nogginto-board and board-to-board surfaces are glued, and that the required setting time is allowed. f Remove any excess glue for neatness. g ny localised board shaping to be made at the point of installation should be carried out with a sharp knife or fine-toothed saw. h void nuisance dust from cutting operations lying on boards prior to installation. i lways use sharp-edged cutting tools. j The length of all nails used should be at least twice the thickness of the board being fixed. k Pigtail screw length should be twice the thickness of the board being fixed, less 5mm. l ll board to board joints must be tightly butted. Vapour barriers Glass-reinforced aluminium foil-faced BeamClad /F provides an excellent vapour seal. For integrity of the foil, all edges should be taped (with a minimum 75mm wide) plain foil tape. Idenden T 303 tape is recommended as being suitable. Taped joints also prevent damage to foil edges during construction. Board joints (glued) No glue is required where boards meet wall or soffit surfaces, except in cases where a temporary fix to flange faces may be advantageous to the work sequence. Close contact between boards at joints is always essential. Painted steel Painting of structural steelwork is not always essential for corrosion protection. BS 8202: Part 1: 1995 permits the use of unpainted steel which is both interior to the building and in an area which will be constantly heated. BeamClad thickness In selecting BeamClad thicknesses, due consideration must be given to the required period of fire resistance and the Hp/ value of the steel sections concerned. Technical advice Unquestionably, some situations will arise which will not be covered in this guide. In such circumstances contact Rockwool for advice, especially where composite concrete floors require fire resistance upgrading.

Description Rockwool Fire Barrier has a 25mm galvanised wire mesh stitched with wire to one face to produce a flexible Fire Barrier with optional aluminium foil faces. Rockwool Fire Barrier Slab has a factory applied foil finish to both faces. Rockwool Fire Barrier and Fire Barrier Slab achieve a reaction to fire classification of 1 as defined in BS EN 13501:1 Rockwool Fire Barrier systems have been developed to inhibit the spread of flames, heat and smoke through concealed spaces in buildings and improve sound reduction. The fixing solutions described in this data sheet have been designed to simplify detailing and incorporate, where possible, commonly available building fasteners and components. pplications and design Rockwool Fire Barrier solutions can be applied as a hanging curtain or as a friction fitted slab. The barrier is continuously supported and secured to the soffit at its head. t the base it is preferable in a cavity barrier situation to wire the barrier to the ceiling grid although it is acceptable to let it drape freely, turned back across the ceiling. If the Fire Barrier is to form a continuation within a void of a fireresistant wall/partition, it is essential to fix the barrier to the wall/partition head to maintain integrity.

27 1 2 hour Cavity Barrier Typical fixing methods Figures 1 6 show typical details for Fire Barrier applied to a timber truss construction as a half hour cavity barrier within the roof space to satisfy the requirements of Building Regulation B3 (4). If the truss is constructed from a minimum timber size of 35 to 49mm thick, both sides of all truss members/bracing require protection from fire in order to minimise charring. Figure 3 shows strips of 50mm Fire Barrier used on the reverse side of the truss for this purpose. lternatively, a second layer of Fire Barrier may be applied to provide 1 hour fire rating (see Fig 17). Nail plate fixings may fail prematurely in fire unless protected (see Fig 6). The new Rockwool fixing system incorporates an angle support and clamping plate. For fixing to timber, the Rockwool clamping plate is used, compressing the barrier to the timber, fixed at 450mm centres using No. 10 woodscrews. For fixing to concrete soffits, the pre-punched angle support is fixed using Hilti DBZ or Ejot ECL 35 hammer set anchors at max. 750mm centres. For fixing to steel purlins, use Hilti SMD 02Z (5.5 70mm) self-tapping screws at max. 450mm centres. To use the patented Rockwool angle support system, bend tongues out to 90 and impale barrier onto them. The slotted clamping plate is then fitted by pushing the tongues through the slots and these are then bent over the face of the clamping plate completing the process. Rockwool ngle Support The tongue has two positions for bending.

28 1 2 hour Cavity Barrier Typical fixing methods continued Fire Barrier If 30 minutes insulation is required, use 1 layer of 60mm foil faced fire barrier with 100mm vertical over lapped joints (Fig 13). The barrier is otherwise fixed as previously shown for timber construction on page 31. Common details Extended drops Rockwool 50mm Fire Barrier single and double layers can be extended from a 3.5m drop to a maximum 6m drop by fixing an additional 2.5m section stitched with overlapped joints as per Figure 14. For drops over 6m in length please refer to Figure 30 (back page). Wire stitching of butt joints in Rockwool Fire Barriers djacent barriers must be closely butt jointed, or overlapped, and through stitched with 0.9mm galvanised annealed wire. It is essential that the barrier provides a good seal at its head, perimeter and at all joints. Where the barrier abuts a profile such as a trapezoidal deck, the material must be cut to suit and secured to fire stop the gap (see Fig.10). For extended drops 1.5mm width galvanised, annealed wire is used. Penetration details It is regarded as good practice to adequately support or reinforce -- services penetrating compartment walls and cavity barriers to prevent displacement. It is recommended that such supports should be no greater than 500mm from each face of the Fire Barrier. To maintain the integrity of the Fire/Cavity Barrier when penetrated by services with a high melting point such as steel or copper pipes, beams or trusses etc., the barrier is first cut locally to accommodate the service or structural member and then re-stitched as neatly as possible. The penetration is then lightly sleeved each side of the barrier to a minimum length of 300mm, using the same barrier material. Each sleeve should be securely stitched to the main barrier to produce a tight seal and prevent future detachment (see figures 14 and 16). Where access is only available from one side, the double seal solution may be replaced by a single collar detail please contact Rockwool for further advice. If the penetrating service is manufactured from low melting point materials such as plastic or aluminium, then sleeving should be extended to at least 1000mm either side of the barrier. This guidance applies to services such as pipes, sheathed cables and conduits, including those carried on steel trays. For protected steel ductwork with a tested fire resistance performance (stability, integrity and insulation) at least the same as the Fire Barrier, 300mm sleeves should be applied either side of the main barrier, as for high melting point services above. For information on achieving fire protection to steel ductwork, please refer to the Rockwool Fire Duct System data sheet. For non-fire protected ductwork, or that with a fire resistance performance less than the barrier, two sleeves should be applied to each side of the barrier. n inner sleeve of 1000mm and an outer sleeve of 300mm. ll sleeves should be stitched to the main barrier. The duct should also include an independently supported fire damper, located in the line of the main barrier. Reference should also be made to pproved Document B of England & Wales Building Regulations Volume 1, Requirement B3, Section 7 and Volume 2, Requirements B3, Section 10.

29 1 hour Fire Barrier Typical fixing methods The unique, patented Rockwool support angle and clamping plate is used to fasten two 50mm Fire Barrier curtains with one support angle without the need for an airspace. The Rockwool support angle has tongues that are pushed out from opposite sides at 300mm max. centres. The Rockwool Fire Barriers are then impaled on the tongues on both sides and clamped using the Rockwool clamping plates. The tongues are finally bent over the clamping plates, completing the system. The system uses 50mm Fire Barrier in a double layer with joints staggered. Note that wire reinforced sides should be placed outwards. Fixing to timber structure (1 hour) When a 1 hour Fire Barrier is supported on structural timber (for example a trussed rafter), and the thickness of timber is 35 49mm, one layer of 60mm Rockwool Fire Barrier must be placed on each side of the timber (see Figure 18). Where timber thickness is 50mm or greater, 2 layers of 50mm Fire Barrier are sufficient.

31 Fire Barrier Slab Fire Barrier Slab offers a new solution to this typical application for up to 4 hours integrity. Rockwool Fire Barrier Slab is an aluminium foil faced slab used to close voids up to 1m in height and 20m in length supported by a masonary wall (minimum density of 400 kg/m 3 ) offering the same fire performance. The slabs are cut to height and friction fitted within the opening. coustic Intumescent Sealant is applied to the butt joints and perimeter of the barrier. Service penetrations The Rockwool Fire Barrier Slab can be penetrated by steel pipes of up to 33mm external diameter or smaller, and steel cable trays of mm or smaller. These penetrating services must be independently supported a maximum of 150mm from the face of the slabs. coustic Intumescent Sealant is applied to form a tight bond where the penetration passes through the face of the slab, as shown in Figure 29.

34 Fire Duct Systems overview and standards The requirements for ductwork fire protection Three performance criteria; stability, integrity and insulation, are required in equal measure for all ducts which pass through fire-rated walls or floors. BS , Clause requires that, for fire-resisting ductwork: The fire resistance of the ductwork, when tested from either side, should not be less than the fire resistance required for the elements of construction in the area through which it passes BS , Clause 9.1 states that: The fire resistance of test specimens shall be the duration in minutes, of heating in accordance with until failure occurs according to one or more of the performance criteria, ie, stability, insulation, integrity, or until the test is terminated, whichever is the shortest time Fire Duct System test data The Fire Duct products have been tested and assessed by BRE LPC in accordance with BS , Fire tests on building materials and structures Methods for determination of the fire resistance of ventilation ducts. Fire Duct products can be used to provide fire protection to horizontal, vertical, rectangular, circular, ventilation and smoke extract steel ductwork fully in accordance with BS , ducts Type and Type B, Fire outside duct and Fire inside duct. The 1 2, 1, 1 1 2, and 2 hour periods of fire resistance stated in this manual are for stability, integrity and insulation in equal measure. For example, the 60 minutes duct constructions shown are certified for 60 mins stability, 60 mins integrity and 60 mins insulation. Kitchen extract ducts These are subject to separate BS requirements, and are additionally covered for 1 2 and 1 hour protection periods. Fire Duct Systems are third party approved by the Loss Prevention Council Certification board (LPCB) for performance and quality and are listed in the "Red Book" - certificate no. 022f. Certificates can be accessed online at or System options rectangular ducts Welded pin fixing method ttachment by welded pins allows extremely rapid installation with slab joints simply butted together. Welded pins are generally spaced at 350mm maximum centres along the length of the duct and at at 500mm maximum centres across the width and depth of the duct. Pins are required on all four sides of vertical ducts, but may be omitted from the top face of horizontal ducts (see page 41). Longitudinal corner joints fixed with pigtail screws at 250mm maximum centres (screw length to be 2 slab thickness). Side wall slabs must overlap top and bottom slabs (as shown). Cross joints bonded with FirePro Glue. lternative joint methods Instead of pigtail screws, longitudinal joints can be fixed with FirePro Glue and nails, at 500mm max. centres. Instead of glue, cross joints can be protected with centrally positioned, 100mm wide Fire Duct strips fixed along both edges with pigtail screws at 250mm max. centres. Mitre-joint fixing methods The use of mitre-joints at slab corners allows installation in situations where welding may not be practicable. Nails are generally spaced at 500mm maximum centres (see page 31). See Fire resistance table on page 30 for limitations on duct sizes. Mitre-joint method ll joints bonded with FirePro Glue. Longitudinal corner joints secured with nails while FirePro Glue cures. 28

35 System options circular ducts Fire Duct Section Circular steel ducts of between 60mm and 356mm diameter may be protected using Fire Duct Section. Fire Duct Section must be glued with FirePro Glue at the joints and in the grooves. Steel bands or wires must be fitted circumferentially to the system at 300mm nominal centres to hold all joints and grooves tightly closed while the glue cures. Figure 1 Fire Duct Section applied to circular duct Where required, cover strips and bearer protection pieces are to be cut from Fire Duct Section (or Fire Duct PSM) of the appropriate diameter. The foil covering is to be removed from the area of Fire Duct Section immediately beneath the cover strips prior to gluing into position and securing with steel nails or pins. Self adhesive aluminium foil tape may be used to seal the joints where a vapour barrier is required. The hanger system is as described on page 40, with the angle bearer formed into a circular shape to suit the diameter of the duct or the Fire Duct Section (depending on whether the hanger is located inside or outside the protection). Fire Duct Section is used to protect the drop rods as described on page 40. General installation principles are as otherwise described in this manual for Fire Duct Slab Fire Duct PSM Circular steel ducts of 406mm and greater diameter may also be protected using Fire Duct PSM. Fire Duct PSM must be glued at the joints and in the grooves with FirePro Glue.

Where there are constructional options within DW/144 and DW/142, these are expanded upon below. These details are primarily concerned with duct joint types and the suspension method. DW/142 flanged cross joint types J3, J4, J5 and J6 are acceptable for use with the Fire Duct System, without modification. Dimensions Item Duct size (mm) Up to Up to Up to * Maximum hanger centres (mm) Minimum drop rod size M10 M10 M12 Minimum angle bearer (mm) * DW/144 and DW/142 do not specifically cover ducts larger than 3 m wide. Please contact Rockwool for details. Fire Duct Slab, Fire Duct Section or Fire Duct PSM may be installed either outside or inside the hanger system. Bearers will require additional protection only when positioned outside the Fire Duct layer. Drop rods will normally be protected with Fire Duct Section or with Fire Duct Slab blocks (see Figure 4). lternatively, the support steelwork may be sized so that separate protection is not required. Design of this unprotected support method is independent of the Fire Duct System. Protection of hangers outside Fire Duct System Hangers outside the Fire Duct System are protected by cutting a rebate into a block of Fire Duct Slab, Fire Duct PSM or Fire Duct Section. The rebate should be no larger than necessary to accommodate the bearer. The block should be glued and pinned in position (see Figure 3, Option ) or secured using pigtail screws.

43 pril 2009 (replaces September 2008 issue) Construction type Structural Steelwork FirePro Glue (previously Conlit glue) Fire resistant adhesive for FirePro fire protection systems s part of the comprehensive FirePro range of fire protection products, FirePro glue has been specially developed for fixing Rockwool fire protection systems. It is also suitable for glue fixing other suitable Rockwool products where a fire resistant adhesive is needed. Description FirePro glue is a waterbased product with an approximate ph 11, supplied in 17 kg plastic tubs. FirePro glue must always be stirred before use to ensure a uniform product consistency. Generally storage should be made in frost free conditions. Should frost exposure occur, the glue should be thawed out followed by thorough stirring. Frost exposure does not remove curing ability. The use of FirePro glue is not limited to particular temperatures and has been tested when applied to surfaces with temperatures of -10 C and upwards but the curing rate insitu can be affected by: temperature (see Table 1 and 3.2) air humidity thickness of glue layer in a joint air access to glued joint (i.e. not sealed off) Please note that the temperature of FirePro glue must be 5 C or more when being applied to surfaces at lower temperatures.

Fixing boards together is supplemented by nails, pins or staples through noggin board joints, and board board joints. Whilst steel surfaces may be acceptable when just moist to the touch, heavy water droplets, grease, scale oxide, dust etc., should be removed prior to the application of FirePro glue. Testing has shown that even if glued joints are immediately subjected to heavy frost exposure, the final glued joint strength is not threatened, but curing is retarded. Effects of ambient conditions 1. For all year round working, noggins should be cut to provide approximately 0.5mm interference fit into steelwork. Some friction in the fitting is required to satisfy LL conditions and to provide a sensible limit to glue thickness. 2. In typical dry summer conditions of 20 C, curing of the basic glue will occur in approximately 4 hours before cover boards should be added onto the noggins. 3. The setting times of glue in moist air conditions is approximately 6-8 hours if the temperature is above freezing point, or in approximately 1 hour at 20 C. Table 1 Setting times for different conditions Conditions FirePro Glue pprox 20 C dry conditions approx. 4 hours pprox 3 C+ with greater than 24 hours expected moist air conditions -10 C to 0 C Noggins to Steelwork dequate bond forms within 1 hour but full cure may be delayed over 24 hours when temperatures 0 6 C FirePro Glue curing data 3.1 Glue fixed noggins must be allowed to set fully before any attempt is made to fix cover boards. The above TBLE 1 suggests minimum times to allow such setting to occur between BeamClad noggins and steelwork. 3.2 Sub Zero Temperatures: It should be noted that when friction fitted glued joints are exposed to sub zero temperatures either immediately, or at some time during the curing process, an adequate bond stability will form in approximately 1 hour. This bond will be sufficient for cover boards to be applied. Full setting will continue as in TBLE 1 when frost free conditions return, but stability will be provided by the supplementary pins or nails.the final strength of the glued joints will not be affected by exposure to sub zero temperatures during the curing process. 3.3 FirePro glue may be used to attach cover boards onto cured noggins (and in glued board joints) provided that a 24 hour interval is acceptable before further trades work on such protected steelwork. Health and safety Material Safety Datasheet is available from Rockwool Customer Support ( ) to assist in the preparation of risk assessments as required by the Control of Substances Hazardazous to Health Regulations (COSHH). Exhaustive testing has been made under various application conditions. LL noggins fitted into steelwork should be cut to provide an interference friction fit of approximately 0.5mm. Excessive oversizing causing the noggins to bend should be avoided. (Fig 1.) The noggins should be installed so as to be just proud of the flange tips. For web depths greater than 500mm solid noggins or T noggins of BeamClad must be used. gain a nominal 0.5mm interference fit is recommended for LL ambient conditions, but particularly for winter working. i or More information For further details visit our website at phone Customer Support ll noggin edges in contact with steelwork must be glued.

Slab size: mm Cavity Linear metres Linear metres No of fixings width per slab per pack required (mm) (m) (m) per pack Typical specifications Curtain Walling The cavity fire stop between the edge of the concrete floor slab and curtain walling is to be Rockwool SP 60 or SP 120 Firestop Slab as manufactured by Rockwool Limited, Pencoed, Bridgend CF35 6NY to provide 1 hour or 2 hour fire resistance for both integrity and insulation criteria (LPC assessment CC89697). Fixings are to be Rockwool SP/S or SP/L Fixing Brackets, fixed in accordance with the details given in the this data sheet. Slabs should be cut to suit the width of the as-built cavity, allowing an additional 3 5mm for compression, and securely fitted into the void. ll joints are to be tightly butted. (Please see *Curtain Walling and External Cladding Systems, below). Masonry wall cavity The cavity barrier is to be Rockwool SP 60 or SP 120 Firestop Slab as manufactured by Rockwool Limited, Pencoed, Bridgend CF35 6NY to provide 1 hour or 2 hour fire resistance for both integrity and insulation criteria (LPC assessment CC89697). Fixings are to be Rockwool SP/S or SP/L Fixing Brackets, fixed in accordance with the details given in this data sheet. *Curtain walling and external cladding systems Rockwool SP FireStop Slabs will provide fire stopping in conjunction with a stable, external façade system. If, during a fire, the behaviour of the facade panel or its fixing is such that a gap develops between the Rockwool SP FireStop Slab and the panel allowing fire to pass through, Rockwool Limited cannot accept liability for failure. Specifiers should ensure that the choice of the curtain walling components will not diminish fire-stopping requirements. Curtain walling systems are manufactured from a wide range of materials which react differently in fire. Large scale independent UK investigations have shown that some glazed or aluminium external cladding systems are liable to integrity failure under fire attack within short periods of time 5 and 20 minutes respectively. Steel faced composite panels filled with combustible insulation can be unstable under fire attack. Curtain walling systems incorporating fire-sensitive panels may suffer severe movement and buckling, resulting in gaps forming between the panel and the Rockwool SP FireStop Slab. Ordering There are 4 slabs per standard pack. Please quote Rockwool SP 60 or SP 120 Firestop Slab and the number of packs and brackets required. The chart opposite may assist estimators. Health and safety Current HSE CHIP Regulations and EU directive 97/69/EC confirm the safety of Rockwool mineral wool; Rockwool fibres are not classified as a possible human carcinogen. The maximum exposure limit for mineral wool is 5mg/m 3, 8 hour time-weighted average. Material Safety Data Sheet is available from Rockwool Customer Support ( ) to assist in the preparation of risk assessments, as required by the Control of Substances Hazardous to Health Regulations (COSHH). Environment Relying on entrapped air for its thermal properties, Rockwool insulation does not contain (and has never contained) gases that have Ozone Depleting Potential (ODP) or Global Warming Potential (GWP). Rockwool therefore complies with the relatively modest threshold of GWPL5 included in documents such as the Code for Sustainable Homes. Rockwool Ltd is increasingly involved in recycling waste Rockwool material that may be generated during installation or at the end of life disposal. We are happy to discuss the individual requirements of contractors and users considering returning Rockwool materials to our factory for recycling.
