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
As part of the comprehensive FirePro range of fire
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

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.

Composition and manufacture
BeamClad is manufactured primarily from a melt of volcanic rock and
limestone. The molten rock is spun into a wool and immediately
impregnated with special resins for handling and shaping. The
material is then compressed, cured and formed into boards.
BeamClad boards are sized 2000 1200mm, in a range of thicknesses
from 25mm up to 60mm.
Board densityNominally 167 180 kg/m3.
For high impact protection systems on beams and columns please
refer to ColumnClad data sheet.
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.

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.

Description, performance and properties
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.

Rockwool Limited reserves the right to alter or amend the specification of products without notice as our policy is one of constant improvement.
The information contained in this data sheet is believed to be correct at the date of publication. Whilst Rockwool will endeavour to keep its publications up to date, readers will appreciate thatbetween publications there may be pertinent changes in the law, or other developments affecting the accuracy of the information contained in this data sheet.
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

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.
For additional fixing details not covered, please contact Rockwool.

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
As part of the comprehensive FirePro range of fire
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
