RE: Project: Re‐Roof 253 Royal Palms Dr
Atlantic Beach, FL 32233
SUBJECT: TPO 60 MIL Installation Instructions
To Whom it May Concern,
We would like to provide a summary of the TPO Roof System installation process for your convenience. We have also included all of
the relevant installation instructions for the ISO board, and TPO Mechanically attached 60 mil system. Please review and let us know
if you have any questions or require additional information:
The existing structural metal deck is a PBR MBCI metal panel; the flutes are approximately 8.75” wide. We will fill the flutes with an
EPS Flute filler insulation that is 1.5” thick and specifically made for this layover / recover system. We preliminary fasten each EPS
flute filler. Once the EPS is installed we will overlay with a 1.5” ISO board, in 4x8 sheets and fasten each 4x8’ sheet with 8 fasteners
and plates. New nailers are installed at the perimeter edge.
The 60 Mil TPO System then goes over the ISO and is mechanically fastened at 12” OC in the field and 6” OC at the Perimeters
We follow the manufacturer installation instructions for all flashings. We will add a standard edge metal to tie in the system, as is
standard practice.
We have attached JM insulation and TPO Installation instructions as well as a specification for TPO.
Thank you very much for the opportunity to provide this proposal for our construction services.
Sincerely,
Sean M. Corrigan, CHST

Roof Insulations
1.0 Product Information
Effective roof insulation helps lower overall energy consumption,
reduces HVAC equipment requirements, and brings about
improved comfort for the occupants of a building.
JM provides these benefits with a full line of high performance
insulations and cover for single ply, built-up, metal and modified
bitumen roofs. The section that follows reviews the storage,
installation and use instructions for the cover board and
insulation board product lines. JM product line. Prior to product
selection, it is recommended that the product performance,
design and installation concepts of the roofing system be
considered to ensure the correct product selection.
The Fesco product line incorporates recycled cellulose and
has been third-party certified for recycled content by UL®
Environment. With an average recycled content of 27% to 40%,
this product line can provide LEED® points (certified products)
in certain jobs. The JM polyisocyanurate product line has
product comprised of a closed-cell polyisocyanurate foam core
bonded in the manufacturing process to various facers (glass-
reinforced, paper, coated glass and aluminum foil). Finally, the
Invinsa® product line includes high-density polyisocyanurate
cover boards that are lightweight with high compressive
strength. These boards provide improved hail resistance and
foot traffic resistance.
2.0 Guarantees
It is also important to protect a roofing system with a guarantee
of performance. JM offers a wide variety of Peak Advantage
Guarantees, including many 20-year No-Dollar-Limit (NDL)
specifications which are available from NDL Approved
Contractors only. Check with a JM Technical Services Specialist
for the names of approved NDL Contractors in your area and
details on NDL guarantees including extended term guarantees.
3.0 Product Considerations
3.1 Insulation Characteristics. Roof insulation performs two
basic functions in any roof system. It is the primary thermal
barrier for the top surface of the building envelope, and it serves
as a base for the roofing system. In order to perform these two
functions successfully, any roof insulation should have the
following characteristics:
■■ Sufficient thermal resistance (“R” Value) to meet the
designer’s needs.
■■ Resistance to indentation, compression and crushing
during installation of the roof membrane and during periodic
maintenance, once the roof is completed. Cover boards are
always recommended by JM.
■■ Rigidity to support the roof membrane and to span the rib
openings of metal roof decks.
■■Resistance to moisture absorption.
■■Dimensional stability.
■■ Compatibility with common roofing systems and attachment
techniques.
■■ Resistance to wind uplift, and pull-through of mechanical
fasteners.
■■ Acceptability by Underwriters Laboratories® Inc., FM Global®
and code agencies.
4.0 Design Considerations
4.1 Drainage. Proper drainage must be provided on all roof
systems. Standing or ponded water hastens the deterioration of
any roof system since the water can work its way through laps
or any minor application flaw in the membrane.
4.2 Double Insulation Layers. Installing roof insulation in
multiple layers provides the designer with improved thermal
performance. It also contributes to the overall performance of
the roof system for the following reasons:
■■ Recent studies indicate that as much as 8% of the thermal
efficiency of the insulation can be lost through the insulation
joints and exposed insulation fasteners of single layer
installations. Insulation joints that are staggered in multiple
layer installations block the flow of heat.
■■ Multiple layer insulation installation reduces the stress
accumulation of a thick, single insulation joint and distributes
the stress more evenly over the multiple, thinner insulation
joints.
■■ The bottom side of the membrane is protected from physical
damage from insulation plates and fasteners by the second
layer of insulation.
■■Roof decks are stiffened.
5.0 Insulation Installation Considerations
5.1 Protection from Weather. JM Roof Insulations (polyiso,
Invinsa, and Fesco) are shipped with plastic shrouds that
are intended to temporarily protect the insulation while in
transit. Polyiso packaging from some JM plants is considered
tarpless; meaning it can be shipped without covering the load
with a tarpaulin. JM plants without tarpless packaging ship
polyiso with loads covered by a tarpaulin. Please contact
your technical representative to learn which JM factories use
tarpless packaging.
All JM insulation products (no matter how shipped), that are
stored outdoors, must be stored in accordance with Johns
Manville, NRCA (National Roofing Contractors Association) and
PIMA (Polyisocyanurate Insulation Manufacturing Association)
best roofing practices using a weatherproof covering such
as a tarpaulin. In humid climates, JM recommends slitting the
plastic shrink wrap (or removing the packaging all together),
prior to covering the pallet with a breathable tarpaulin, to allow
for venting. Furthermore, JM insulation should not be stored in
or around standing water. JM recommends 3" to 4" of dunnage
below individual pallets of insulation to keep it off the ground.
RS-7386web 2-13 (Replaces 12-12)
Roof Insulations
Insulation should not be left exposed to weather. No more
insulation should be installed than can be completely covered
with membrane on the same day. Factory packaging should not
be relied upon as protection from the weather.
5.2 Asphalt Temperatures. JM endorses the guidelines
established by the NRCA and ARMA for heating asphalt for
proper insulation applications. Asphalt should be applied at the
Equiviscous Temperature (EVT), ± 25°F (±14°C).
5.3 Cold Weather Application. Hot asphalt chills rapidly at
40°F (4°C). To avoid problems associated with “cold” asphalt
application, insulation should be applied with mechanical
fasteners or the “mop and flop” method of installing insulation.
The “mop and flop” method entails mopping the back of the
insulation so that the asphalt retains its adhesive qualities for a
longer period. When applying insulation with hot asphalt, board
size should not exceed 4' x 4' (1.22 m x 1.22 m). Care should be
taken in any application below 40°F (4°C).
5.4 Mechanical Application to Steel Decks. Mechanical
attachment of insulation to steel decks is the only acceptable
attachment method. For current information regarding Factory
Mutual requirements over insulated steel decks, please check
with a JM Technical Services Specialist, or the current FM
ApprovalsSM RoofNav.
5.5 Cold Adhesive Application. JM insulations may be installed
in Insulation Adhesives:
■■MBR Bonding Adhesive
■■One-Step Foamable Adhesive
■■Roofing Systems Urethane Adhesive
5.6 Foam Insulation Products are Combustible. They should be
properly protected from exposure to fire during storage, transit
and application.
5.7 Limitations. When installed over metal decks, spans shall
be limited for specific deck gauges as outlined in the current
FM Global® Loss Prevention Data Sheets 1-28, 1-29 and FM
ApprovalsSM RoofNav. JM insulations are not recommended
for applications where temperatures are outside the service
temperatures of -100°F to 250°F (-73°C to 121°C). Although
JM roof insulations are designed to be compatible with most
membranes, the membrane manufacturer should be consulted
for specific approval with individual membrane products.
6.0 Foam Thermal Values
6.1 Thermal Values. The thermal values of all closed cell
urethane or isocyanurate foam insulations are at their optimum
at the time of manufacture. As these products “age,” some
thermal loss occurs due to air infiltrating the foam cells and
diluting the insulating gas in the cells. This process continues
to occur over time. The degree to which this occurs is a
function of the product formula and quality. It may vary from one
manufacturer to another. The ultimate R-value of foam products
will also depend on individual installation circumstances.
6.2 Long Term Thermal Resistance (LTTR). Johns Manville
manufactures polyisocyanurate foam insulation products and
reports R-Value in accordance with ASTM C 1289-12 and CAN/
ULC S704. LTTR is a test procedure for a foam insulation with
blowing agents other than air, giving a Thermal Resistance value
in a 15 year time-weighted average. This method provides a
more accurate method to report long term thermal performance
for foam plastic insulation materials.
7.0 Definition of Terms and Symbols
7.1 k-Value (Thermal Conductivity): the measurement of heat
flow in BTUs through a 1" (25 mm) thickness of any single
homogeneous material, per hour per sq. ft. per degree F
temperature difference (W/m • °C).
7.2 C-Value (Thermal Conductance): the measurement of heat
flow in BTUs per hour per sq. ft. per degree F temperature
difference through any single material, regardless of thickness
(W/m2 • °C).
7.3 R-Value (Thermal Resistance): the measurement of the
resistance to heat flow. The reciprocal of the C-value.
7.4 U-Value (Overall Heat Transfer Coefficient): the
measurement, in BTUs of heat flow, per hour per sq. ft. per
degree F temperature difference through a combination of
materials such as roof deck, vapor barrier, roof insulation,
built-up roofing, and the air films below and above such
combinations.

Specification ST6RM–S
RS-8663 9-08 (New)
General
This specification is for use over any approved structural steel deck which is
suitable to receive a mechanically fastened insulation. This specification can
also be used in certain re-roofing applications.
Install insulation in accordance with the appropriate JM insulation
specification detailed in the current JM Single Ply Roofing Systems Manual.
• Insulation: Mechanically fasten using UltraFast Fasteners and Plates
• Membrane: Secure using High Load Fasteners and Plates
Note: Consider all general instructions contained in the current JM Single Ply
Roofing Systems Manual as part of the specification.
Design
Consider local conditions and characteristics when designing, specifying and
installing any roofing system. Information from the Single Ply Roofing Industry
(SPRI), FM Global® and local building codes can provide guidelines for the
designer.
Design and installation of the deck and/or roof substrate must result in the roof
draining feely to outlets numerous enough and so located as to remove water
promptly. Minor ponding is acceptable.
Deck Preparation
Ensure the deck is clean, dry and smooth so that the insulation lays flat. Steel
decks must be a minimum 22 gauge (0.76 mm) and FM–approved fastening
methods must be followed to achieve the desired uplift. Please check with the
deck manufacturer for further guidelines.
Insulation Fasteners and Plates
Install UltraFast Fasteners and Plates at a minimum rate of five fasteners per
4' x 8' (1.22 m x 2.44 m) board. Fasteners must pierce the top flute of the deck at
a minimum of 1" (25 mm).
Insulation Application
Store products per manufacturer’s recommendations. Remove any wet product
and discard.
Ensure the maximum width and length of ENRGY 3 insulation does not exceed
4' (1.22 m). Recommended minimum width is 6" (152 mm).
A minimum offset of 6" (152 mm) is recommended from the previous layer of
insulation. The top layer of insulation must be a minimum 1.4" (36 mm) thick.
Position the insulation with the long side of the board running parallel with
the flutes of the deck. Each of the edges must be centered on the flute top.
No board widths less than 6" (152 mm) are allowed. Perimeters and corners
fastener density must be enhanced per FM publication 1-29. Call JM Technical
Services at (800) 922-5922 for specific approvals for ENRGY 3 insulation.
Membrane Application
Before installation, unroll the JM TPO Membrane, and “relax”:
• 15 minutes when the temperature is above 60°F (16°C)
• 30 minutes when the temperature is below 60°F (16°C)
Position the membrane so that all field sheets run perpendicular to the flutes of
the deck. Begin fastening once the membrane has been properly positioned.
Membrane Securement – Mechanically Fastened
Install High Load Fasteners and Plates in the 5" (127 mm) lap at a minimum rate
of one fastener every 12" (305 mm) on center. Position plates so that the back
edge of the plate is no closer than ½" (13 mm) from the edge of the membrane.
Fasteners must pierce the top flute of the deck a minimum of 1" (25 mm).
Welding of Lap Areas
The laps of JM TPO mechanically fastened systems must be hot air welded.
Clean all surfaces to be welded. Follow manufacturer’s operating instructions
for welding equipment. All welds must be a minimum of 1.5" (38 mm) in width.
Quality Control of Seams
After heat welding, check the seams for integrity with a blunt-ended probe.
Repair any cold welds or “fishmouths”. Each day, take test cuts at the seams
and pull until failure to test the quality of the welds. Should the welds be
deficient, a more thorough examination of the work performed must be carried
out and necessary repairs made.
Perimeter Attachment
Secure attachment of the TPO roofing membrane at the perimeter and at
penetrations by mechanically fastening using High Load Fasteners and Plates
or other approved fasteners appropriate for substrates.
JM allows the use of picture framing with half sheets, or adding additional rows
of fasteners in the field sheet and welding a 6" (152 mm) minimum width cover
strip. The minimum width of the perimeter enhancements should be 6' (1.83 m).
Increase perimeter width as necessary to comply with FM 1-29 and 1-28.
