2. Threaded portion of the fastener must engage the deck.
C. The Firestone contractor will contact Firestone Technical Services for approval of fasteners to be used with other substrates prior
to installation.
D. Insulation attachment is not required for Ballasted or PMR Systems.If insulation attachment is specified,acceptable plastic
insulation plates which lock and recess the fastener heads shall be used.Contact Firestone Technical Services for a list of
acceptable insulation plates and additional special precautions and requirements in the event that insulation attachment is
considered.Expanded Polystyrene Insulation shall not be pre-attached.
E. The Firestone contractor will contact Firestone Technical Services for approval of any non-Firestone fastener and plate for
attachment of Firestone accepted insulation prior to job start-up.
F. The Firestone contractor will determine the puN-out resistance for all substrates(wall or deck)which will receive mechanical
attachment of the roofing system(i.e.:base tie-in securement)to assure that the substrate will provide a minimum pull-out
capacity of 200 pounds per fastener.
G. If tested pull-out values do not meet the minimum Firestone requirements,additional attachment requirements will be necessary.
H.The Firestone fastener will be used for membrane installation and termination.
I. The fastener and plate will be used for insulation installation and attachment.
2.04 OTHER FIRESTONE ACCESSORIES
The Ballasted System will consist of all Firestone supplied or approved materials.Attached please find the Technical Information
Sheets that contain the product data requested for this project,for Firestone supplied materials.
PART 3 - EXECUTION
3.01 ROOF SUBSTRATE PREPARATION
A. All substrates to which the Ballasted System is installed will be properly prepared prior to membrane installation.The surface will
be clean,dry,smooth,free of sharp edges,fins,loose or foreign materials,oil,grease and other materials which may damage the
membrane.All roughened surfaces which could cause damage to the membrane will be properly cushioned with insulation.All
surface voids of the immediate substrate greater than'/:wide will be properly filled with an acceptable insulation and
subsequently mechanically attached.Ponded water,snow,frost and/or ice,present in more than trace amounts,will be removed
from the work surface prior to installation of the Ballasted System.
B. The following is a chart of substrate requirements for the Ballasted System:
Chart of Acceptable Substrates
Type of Substrate Ballasted System
Steel(Minimum 22 Gauge) Insulation required
Structural Concrete(Minimum 3000 psi) Insulation required
Plywood or Oriented Strand Board(Minimum'AC thick)' Insulation required
Wood Planking(Minimum'it'thick) Insulation required
Poured or Pm-cast Gypsum and Cementitious Wood Fiber Insulation required
Lightweight Concrete Decks and Fills(New Construction) Moisture resistant insulation or Firestone Protection Mat required'
Smooth Surface Built-up Roofs' Insulation required''
Coal Tar Pitch and/or Gravel Surfaced Built-up Roofs'•'' Insulation required'
Mineral Surface Built-up Roofs' Insulation required'
Sprayed In-Place Urethane Total tear-off required
Existing Roofs that are Removed insulation required
Notes: 1. Pre treated plywood may be used.provided it has not been treated with ammonium phosphates.
2. Moisture resistant insulations include firestone Extruded or Bonded polystyrene(EPS).The use of other Insulation will require the installation eta vapor fetarder between
the lightweight concrete deck and the insulation.Contact riralene Technical Services for additional retleirements.Prokdian Mat is not acapubk if existing root is removed.
3. The Ballasted and PMR Systems maybe installed directly overanesisdng smooth surfaced built-up root which has net been re-saturated or coated.
4. CAUTION:Flaw of existing coal tar into the building may occur when new fasteners penetrate an existing coal tar pitch membrane.
S. The removal d loose gravel may be required to meet local building cede requirements.II loose gravel is removed.some method of leveling may be required to provide a
suitable substrate tar insulation.

4.0
C. A vapor retarder will be installed in accordance with the project specifications.
D. For re-roofing applications only:all existing roof system components will be removed in accordance with the specifications. If
unspecified detrimental components are discovered during installation,they will be brought to the attention of the project designer
for corrective action under provisions for unanticipated additional work.
3.02 WOOD NAILER LOCATION AND INSTALLATION
Wood nailers will be installed in accordance with the specifications.Wood nailers in a recover situation will be pressure treated(i.e.
"Wolmanized"or Osmose K-33).
3.03 INSULATION INSTALLATION
Only as much insulation as can be covered with roofing membrane and completed before the end of the day's work,or before the
onset of inclement weather,will be installed.Insulation will be neatly fitted to all penetrations,projections,and nailers.Insulation will
be loosely fitted,with gaps not greater than'/;.All gaps greater than 1/4'will be filled with insulation of the same type.Under no
circumstances will the membrane be left unsupported over a space greater than'/<".Tapered or feathered insulation will be installed
around roof drains so as to provide proper slope for drainage.When installing multiple layers of insulation,all joints between layers
will be staggered.
3.04 FIELD MEMBRANE
The RubberGard System wilt be installed so that field and flashing seams shed water(shingle type fashion).The membrane panels will
be placed(loose laid),without stretching,over the acceptable substrate and allowed to relax for a minimum of 30 minutes before
bonding.As ambient air temperatures decrease,the relax time for the membrane will increase.Subsequent membrane sheets will be
installed in the same manner,overlapping the adjoining sheets a minimum of 3'.
3.05 BALLAST
The ballast shall be spread over the completed RubberGard System at the rate specified by the project designer,but never less than 10
lbs./sq.ft.using ASTM#4 stone.Ballast materials will be spread the same working day.Ballast may be spread over the membrane
using soft rubber-tired ballast buggies.Ballast will be spread around penetrations by hand.At areas where ballast is loaded,the
membrane and underlying insulation will be protected using insulation or plywood over an additional layer of EPOM.Any ballast
displaced by a walkway shalt be distributed around the pad,to maintain the specified average ballast rate.
3.06 PROTECTION MAT
When specified,the Firestone RubberGard Protection Mat will be unrolled over the membrane overlapping a minimum of 6 inches
(Wetting the mat or roof membrane wilt facilitate the handling.)An additional layer of Firestone RubberGard Protection Mat will be
overlaid around all projections,pipes,vents,drains,etc.,ensuring 12"minimum overlap.Firestone RubberGard Protection Mat shall
extend up all vertical interruptions,slightly higher than the ballast stone.Firestone RubberGard Protection Mat shall extend around all
paving blocks a minimum of 2"in all directions.
3,07 MEMBRANE LAP SPLICING
The 3°end and side laps will be spliced using Firestone QuickSeam Splice Tape or Firestone Splice Adhesive in accordance with
current Firestone procedures.
3.08 MEMBRANE SECUREMENT(BASE TIE-IN)LOCATION AND INSTALLATION
The membrane(base tie-in)will be secured at all locations where the membrane ends or goes through an angle change greater than
2'in 12"(i.e.roof edges,curbs,interior walls,etc.).It is not necessary to secure the membrane at round penetrations less than 18'in
diameter or square penetrations that are less than 4"square.
3.09 FLASHING—PENETRATIONS,WALLS PARAPETS MECHANICAL EQUIPMENT CURBS,
SKYLIGHTS,GRAVEL STOPS OR ROOF EDGE METALS, ETC.
All Penetrations,Walls,Parapets,Mechanical Equipment Curbs,Skylights,Gravel Stops or Roof Edge Metals will be flashed in
accordance with current guidelines in the Firestone Technical Specification Manual.

3.11 SHEET METAL WORK
The Firestone EdgeGard system will be installed(if required in the specifications)in accordance with Firestone Technical
Specifications.All other sheet metal work not supplied by Firestone,will be fabricated and installed in accordance with the
specifications and SMACNA recommendations.In instances where Firestone requirements exceed the requirements of SMACNA,
Firestone requirements will take precedence.
