X(59) (K2)CI/SfB

Rockwool supports FIRAS

accredited installers

2Description

Ablative Coated Batts are manufactured by spraying high-density

Rockwool with a fire rated ablative coating.

The Ablative Coated Batts are simply cut and friction fitted between

the services and the edges of the structure.* The fire rated coating is

used as an adhesive to bond sections of batt together into a barrier

and to the surrounding structure. All joints in the batt are pointed in

with Acoustic Intumescent Sealant to form a monolithic layer.

* Plastic pipework needs to be sleeved with Rockwool Corofil Firestop

Pipe Collars prior to installation of the Intumescent Coated Batts.

These must be mechanically fixed with steel angles, min 30mm

30mm 1.6mm, or similar to the surrounding substrate.

For large floor openings we would advise using Rockwool Corofil

Firestop Compound (see data sheet).

3Construction type Cavity Barriers

Access Floor FireStop Cavity re stop solution for voids below access oors

Patent app. 97304156.9


protection products, Rockwool Access Floor FireStop

is a specifically developed product, designed to

provide cavity fire stops for use in voids between

raised access floors and the floor slabs.

The product has been designed as a one-piece system

and affords easy cutting and installation. It offers

unique lateral compression to allow tightness of fit.

The product is available in two versions:

AF 30; giving 30 minutes fire resistance.

AF 60; giving 60 minutes fire resistance.

Advantages

Easy to cut and install. Ensures site tolerances are accommodated. Tested over 60 minutes fire resistance. Excellent acoustic performance. Resists the passage of smoke aluminium foil faced on both sides. Provides excellent lateral compression. Suitable for cavity heights up to 600mm. Available in slabs or strips.

Description, performanceand propertiesDimensions

Rockwool AF 30 FireStop1200 x 1000 x 100mm thickness

Rockwool AF 60 FireStop1200 x 1000 x 120mm thickness

The products are faced on both sides with reinforced aluminium foil

to give Class O rating and excellent smoke resistance.

The slabs are designed to be cut on site to produce cavity fire stops of

1000mm length and in widths to suit individual floor void depths

between 50 and 600mm.

Standards and approvals

Rockwool AF 30 and AF 60 Access Floor FireStops have been tested and

assessed in accordance with BS 476: Part 20 1987 and have achieved 30

minutes and 60 minutes fire insulation and integrity respectively. LPC

Test Report TE 91727 and Assessment number CC91988 refers.

Performance

FIREThe base stone wool of Rockwool Access Floor FireStop is inherently

non-combustible. Rockwool products will withstand temperatures in

excess of 1000C.

ACOUSTICWhen used below access floors Rockwool Access Floor FireStops will

reduce appreciably the levels of airborne sound transmission through

the floor cavity.

RESISTANCE TO MOISTURERockwool Access Floor FireStops are water repellent.

GENERALFor the chemical and physical characteristics of Rockwool materials

see Data Sheet 001 Performance and properties.

Access Floor FireStop installed below a typical access floor

Rm1(23) (K2)CI/SfB



4Sitework

Access 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 Access Floor FireStop cut to

suit the dimension.

Pieces cut to required depth are also available.

Cutting should be along the 1000mm Axis only.

The fixing sequence is as follows:

1. Cut the Access 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 Access Floor FireStop.

3. The vertical joints between individual AF 30 or AF 60 Access Floor

FireStops should be sealed with self adhesive class O aluminium

foil tape. This can be used to totally enclose the unfaced surfaces

if required.

VOIDS UP TO 400mmAF 30 and AF 60 Access Floor FireStops do not require any fixing to the

access floor or the structural floor.

VOIDS FROM 401 TO 600mmFor voids above 400mm, AF 60 Access 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 impaled centrally into the base of the

FireStops from alternative sides at 500mm centres. The brackets should

be mechanically fixed to the structural floor using metal fixings.

Service Penetrations

CABLE TRAYS/TRUNKINGServices must be supported on either side of the Access Floor FireStops

at points of penetration. If gaps are created by inaccurate cutting

offcuts of Access 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

Approved 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.

Supply

Please contact the Rockwool Customer Services Department for

6Description

Acoustic Intumescent Sealant is a high specification, one part water

based acrylic sealant, extruded from a cartridge loaded into a

standard sealant gun. The depth of the joint will depend on the gap to

be filled and the fire rating required. (See Fire Rating)

All surfaces must be thoroughly clean and free of bond breaking

contaminants prior to application of the sealant. No priming is

required for most construction substrates; however, it is

recommended that a small area be tested on substrates.

The sealant should not be applied if the ambient temperature is below

5C as adhesion will be impaired.

The sealant is fast curing, approximately 15 minute tack free time.

When fully cured the sealant can be overpainted.

Standards

Rockwool BeamClad fire protection materials have been assessed to

BS 476: Part 21: 1987 for the fire protection of loadbearing steelwork

for up to 4 hours protection, based on tests carried out to BS 476: Part

8: 1972 and BS 476: Part 21: 1987.

High air f low situationsUnfaced BeamClad systems have been evaluated for use in return air

plenums, by the Institute of Occupational Medicine to World Health

Organisation test standards and for use in subways, for train speeds

up to 150 km per hour.

Performance and properties

Fire performanceUp to 4 hours fire resistance for structural steelwork, assessed at

550C and 620C failure criteria. Thicknesses to suit other steel fail

temperatures available on request. The unfaced, foil and tissue faced

products achieve reaction to fire Euro Class A1 in accordance with

BSEN13501-1.

MoistureThe rock wool fibres of BeamClad boards are randomly oriented,

avoiding any tendency to promote capillary action or hygroscopic

moisture absorption.

Moisture content0% in air-dried state.

Moisture absorption0.004% by volume at 20C and 90% relative humidity.

Water absorptionMaximum 60 g/m2 after 24 hour total water immersion testing (i.e.

approximately 1.5% by weight for 25mm plain board).

Construction and installation guidanceA comprehensive range of practical systems is available to meet a

variety of site requirements.

BeamClad dry joint systemsThese use either purpose-made clips, glued mineral wool noggins or

stud welded pins to secure the insulation to structural steel sections. All

board-to-board joints are straight butt joints, without the need for glue.

Pigtail screws (minimum twice the insulation thickness, less 5mm) are

used to secure the insulation boards to each other and/or to the noggins.

BeamClad glued joint systemsThese use an inorganic and non-toxic glue to bind board-to-board joints

and/or to the noggins. Standard flat head nails, twice the thickness of

the insulation, are used as initial supports.

9Installation options

Dry board joint systems:a) Clip fix application

A quick and user-friendly dry joint board system featuring Rockwools

push-fit clips.

The spring action of the clip creates a vice-like grip on the steelwork

flange. The BeamClad board is impaled on to the clip pins and held in

place with spring steel non-return washers. Supplementary pigtail

screws fixed through the side boards into the soffit boards complete

this system.

The clips are located at max. 600mm centres to top flange and max.900mm centres to bottom flange, with pigtail screws for board toboard joints at 150mm centres.

Combined clip and stud welded pin dry joint systemWhere it is not possible to clip fix, eg beneath concrete soffits, stud

welded pins (at the same fixing centres) are used in lieu of the clip fixing.

Hp/A limit for 2 hours = 200

b) Glued noggins application

A fast, easy to apply, dry joint board system where noggins are glued

into position between the steelwork flanges using FirePro Glue

(previously Conlit Glue). Noggins are fixed at 1000mm nominal

centres. The BeamClad boards are then retained by means of pigtail

screws, fixed at 100mm nominal centres to the noggins and 200mm

centres for board-to-board joints.

For beam depths over 500mm a Tee-noggin or full depth solid noggin

is used to provide the support for the cover boards.

C) Stud welded pin application

A dry joint system employing steel welded pins.

The steelwork is cleaned in the area where the welded pin is to be

positioned. The pin is then welded to the steel flange.

The BeamClad board is then impaled on to the stud welded pins and

held in place with spring steel non-return washers.

The stud welded pins are fixed at max. 600mm centres to top flangeand max. 900mm centres to bottom flange. The BeamClad board-to-board joints are then secured by means of pigtail screws fixed at

nominal 150mm centres.

Glued board systems:a) Glue-fixed noggins and board-to-board glued joints

BeamClad noggins (at 1000mm nominal centres) are glued between

the steelwork flanges, and the BeamClad side boards are glued to the

noggins. The BeamClad side boards are also glued at all vertical joints

and horizontal board-to-board joints.

Round head nails (length 2 thickness of board) are fixed through

the side boards into the noggins (min 2) and soffit boards (at 400mm

nominal centres) to consolidate the glued joints.

b) Stud welded pins and board-to-board glued jointsPins are stud welded at max. 600mm centres to top flange and max.900mm centres to bottom flange. All board-to-board joints are gluedand nailed.

The above applications do not necessarily represent an exhaustive list of applications for BeamClad. Rockwool Limited does not accept responsibility for the consequences of using BeamClad inapplications different from those described above. Expert advice should be sought where such different applications are contemplated, or where the extent of any listed application is in doubt.

Board jointing

Butted corner jointsButted corner joints are made with square edge boards using either a

dry joint with pigtail screws as below, or FirePro Glue and nails at

400mm centres.

Axial jointsAll axial joints are made with square butt edges, without nails. Glue is

only required for glued board systems.

For Foil faced products, joints can be finished with Class O foil tape.

NogginsBeamClad boards can be fixed to noggins, cut from BeamClad offcuts

of at least the same thickness as the facia and soffit boards.

The edges of the noggins are glued where they contact the steelwork,

then, once the glue has set firmly, the cover boards are fixed in

position with either pigtail screws or FirePro Glue and nails.

Welded steel pinsBoards are impaled onto stud welded pins and secured with non-

return washers.

Joints and glue

FirePro Glue is an inorganic, non-toxic product with a pH of 11.

FirePro Glue is supplied pre-mixed in 17 kg tubs. A variety of joint

types can be used (see previous page).

Coverage rate will depend on the linear length of the joints, width of

joint (board thickness) and joint depth. Assuming 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.

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. As a very approximate guide, the coverage rate of a 17kg tub of

FirePro glue would be 35m2 of applied board

Supply

BeamClad slabs are supplied on pallets, shrink-wrapped in

polyethylene, 26 pallets per 40 ft container.

A noggin solution which removes the necessity for

glue to board-to-board and board-to-noggin joints.

The board-to-board edge joints are fixed with pigtail

screws at 200mm centres. The glued noggins are at

1000mm fixing centres. This fixing solution can be used

for 2, 3 and 4-sided beam protection for up to 2

hours.

Installation sequence

1 Cut 120mm wide noggins (C) 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

made from cover board thickness. These are then glued into

position at 1000mm centres (D).

2 Cut the BeamClad boards to suit the depth of the beam whilst

allowing for the additional flange cover board thickness.

3 Push board tight to deck soffit and fix pigtail screws through the

coverboards and into the noggins at maximum 100mm centres (B).

4 Fix all board-to-board joints using pigtail screws at

200mm maximum centres (A). Minimum screw length must be

2 cover board thickness 5mm.

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 nogginsWherever three or four-sided protection is required, fixing to noggins

is a practical option. No power supply is required.

Fixing boards with stud welded pinsSituations will always occur where noggins do not afford a

practical choice, e.g. for two-sided box constructions or diverse

perimeter bracketing.

Stud welded pins allow the installer a simple, tested alternative

to noggins.

Installation sequence (noggin fix)

1 Fixing nogginsCut 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 boardsa Apply 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 Apply glue continuously and liberally to all board interfaces.

Tightly butt to adjoining boards and nail through edge joints

with same length nails as for noggins, at 400mm maximum

centres.

Installation sequence (stud welded pin fix)

1 Fit stud welded pins (3mm diameter) as indicated opposite.

2 A selection of pins should be mechanically tested by bending from

the vertical and returning it to the original position.

3 sprung steel non-return washers to secure boards.

4 Apply FirePro glue to all board-to-board joints.

5 Offer up flange boards and nail through glued corner joints at

400mm maximum centres.

6 If using faced boards, apply foil or scrim tape over joints for

uniformity of appearance.

General notesBoard jointing

Butted corner jointsButted 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.

Axial jointsAll 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.

NogginsBeamClad 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.

Welded steel pinsBoards are secured to stud welded pins with non-return washers.

Glue

FirePro Glue (previously Conlit glue) is required between all board-to-

board and board-to-noggin joints for glued systems, but only between

noggin-to- steel joints for dry systems.

Applying 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 20C ambient

temperature.

FirePro Glue is supplied pre-mixed in 17 kg tubs.

Coverage rate will depend on the linear length of the joints, width of

joint (board thickness) and joint depth. Assuming 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.

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. As a very approximate guide, the coverage rate of a 17kg tub of

FirePro glue would be 35m2 of applied board

BeamClad thicknesses to be read with Tables 7, 8 & 9The 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.

A = 25mm

B = 30mm

C = 35mm

D = 40mm

E = 45mm

F = 50mm

G = 60mm

H = 70mm

I = 80mm

J = 90mm

K = 100mm

L = 110mm

Multi-layer applications

When a protection thickness in

excess of 60mm is required, this

can be achieved by plying two or

more layers of BeamClad together.

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.

Apply the outer layer of

BeamClad, supporting the boards

until the glue sets by using nails

of sufficient length to penetrate

completely through the noggins.

Determining protection thickness

1 The table above indicates the effect on Hp/A for three and four

sided schemes.

2 Determine Hp/A factor from the table or by calculating for other

exposure situations, ensuring the correct mass per metre is used.

3 Establish the period of fire protection required.

4 For Hp/A factors in excess of 260, contact Rockwool for advice on

both thicknesses and fixing methods preferred.

5 Bracing members: These do not generally require protection. If

required as an essential element to the fire resistance, use Hp/A not

greater than 200 m-1.

6 Where steel beams are fixed to composite steel and concrete decks,

the profiled re-entrant void may not need additional protection if

allowances for board thickness or steelwork section factor are

made. See the Yellow Book 1.7 for current independent guidance.

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. Avoid

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, noggin-

to-board and board-to-board surfaces are glued, and that the

required setting time is allowed.

f Remove any excess glue for neatness.

g Any localised board shaping to be made at the point of installation

should be carried out with a sharp knife or fine-toothed saw.

h Avoid nuisance dust from cutting operations lying on boards

prior to installation.

i Always 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 All board to board joints must be tightly butted.

Vapour barriers

Glass-reinforced aluminium foil-faced BeamClad A/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/A 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.

Construction type Structural Steelwork

ColumnClad SystemRigid re protection solutions for structural steel columns and beams


protection products, the new Rockwool/Lafarge

ColumnClad system is a fast and efficient method of

providing fire protection to structural steel columns

and beams.

The square edged, gypsum based ColumnClad

boards are extremely robust and impact resistant.

The excellent moisture resistance properties of

the board enables encasement assembly to take

place earlier in the construction programme of the

main building envelope.

The board has a flat white mineral tissue surface

which can be decorated directly or alternatively a thin

plaster skim coat can be applied prior to decoration.

The ColumnClad System has been tested and

assessed by the Building Research Establishment

(BRE) and subsequently reviewed by the Association

for Specialist Fire Protection (ASFP), prior to

inclusion in the Yellow Book. This publication is

regularly reviewed to ensure that it reflects the

current philosophies of steel protection and it is

therefore recommended that the principles of the

Yellow Book are closely followed when a

ColumnClad system is designed and applied.

The non-combustible boards are stapled or screw

fixed to each other around the column or beam to

form a frameless encasement system.

The new ColumnClad board extends the current

tool box of Rockwool fire protection systems for

structural steel columns and beams.

Fire Performance

Reaction to fire classification:ColumnClad achieves an A1 classification in accordance with

BS EN ISO 13501-1:2002. For the purposes of Approved Document B

this is equivelant to a non-combustable product.

Fire Resistance: The ColumnClad frameless encasement system provides up to 2 hours

boxed fire protection to Structural Steel Sections when tested to

BS 476 Part 21. Jointing and finishing is not a requirement to meet the

fire protection levels given, however the inclusion of services should

be considered with caution.

Moisture Resistance

When tested to BS 1230, ColumnClad boards absorbed less than 5%

water by weight after 2 hours total immersion. The ColumnClad

boards can be subjected to moisture throughout their installation,

prior to the building envelope being sealed. When wetted and allowed

to dry, the board will regain its strength and fire resistance.

Finishes

The completed column (or beam) lining provides a robust impact

resistant smooth surface that will accept most kinds of decoration.

The boards can be left unjointed or alternatively a taping and jointing

treatment or skim plaster coat can be applied to give a smooth

seamless finish.

The boards do not require a PVAC sealing coat prior to applying a

decorative paint or plaster skim finish. Direct application may be

applied to the board face subject to the following conditions: Do not decorate boards if damp atmospheric conditions exist. Boards must be dry and free of moisture. Board faces must be clean and free of oil or grease marks. All board joints should be reinforced with Lafarge jointing tape

and filler. Protective angle bead should be applied at external corners Plaster skim finish applied once filler compound has set.

Ceramic Tiling:Tiles can be applied using conventional tile adhesives without

pre-treatment of the board.

Board Fixings

Fixing Options

15mm and 20mm thick ColumnClad boards can be directly fixed to

each other using proprietary 50mm chisel edged staples without the

need for a supporting framework. (Alternatively 20mm boards may be

screw fixed using Lafarge Grabber High Thread screws, without

pre-drilling or counter sinking.)

Note: Only staple fixings should be used to fix single layer 15mm

board encasements.

Components:

Frameless Staple fixing: Use a proprietary gas powered cordless staple gun, fitted with a guide

attachment (Paslode make suitable models). The boards can be stapled

together at max. 150mm centres to form a rigid encasement

protection for columns and beams .

Frameless Screw Fixings: As an alternative to staple fixing, 20mm ColumnClad boards may be

screw fixed together to form a rigid encasement using Lafarge

Grabber High Thread Screws at max 300mm centres (see table below

for sizes).

Double Layer EncasementsWhere 15mm and 20mm boards are required to form a double layer,

apply the 20mm layer first. Board joints must be staggered between

respective layers.

General

ColumnClad boards are suitable for protecting structural steel

columns and beams, with a section factor A/V (Hp/A) up to 260

calculated on the basis of box protection to 3 or 4 sides.

The ColumnClad board will protect universal column and beam

sections listed in the ASFP Yellow book.

Establishing ColumnClad board thickness

In a fire, unprotected structural steel begins to lose its strength at

temperatures around 550C. Selection of the appropriate encasement

is therefore essential. Further guidance can be found in Section 1 of

the ASFP Yellow Book.

To establish the correct board thickness required for steel column

and beam encasements the specifier should follow the procedure

set out below:

1) Locate the appropriate size and mass of the column or beam (for

common sizes see table X on previous page). Read off its Hp/A

Factor depending on whether 3 or 4 sided protection is required.

2) Establish the period of fire resistance required.

3) Refer to the adjoining tables to determine the ColumnClad board

thickness required.

Table 1: Column fire protection (550C)Table 2: Beam fire protection (550C)Table 2A: Beam fire protection (620C)

Note: For castellated sections, adopt the above procedure then add 20%

to the indicated thickness and specify the next highest board.

Example: Column fire protection

Requirement:1 hour fire protection to 203 203 52 kg/m steel column with 4

sided protection

SolutionSection factor Hp/A = 125-1 (from table 1)

Use single layer of 15mm ColumnClad
