Re: Vail Doubletree Roof
Martin/Martin, Inc. Project No.: M17.0085.S.02
Dear Mr. Ranieri,
It is our understanding that the Vail Doubletree hotel at 2211 North Frontage Road West in Vail, Colorado is
proposing a new Therma-Hexx heated paver system to provide a snowmelt system on the flat roofs over the
kitchen and ballroom. As described in a previous letter, the snow load capacity of the roof is below that
required by the town of Vail which requires a snow removal program to limit the depth of accumulated
snow on the roof. The thermal heating system is intended melt snow from the roof preventing excess
accumulations of snow and reducing or eliminating the need for snow removal personnel on the roof.
The proposed Therma-Hexx pavers weigh approximately 1.6 pounds per square foot including fluid and
insulation. The additional weight does not significantly reduce the allowable roof snow load capacity,
however, without proper anchorage, the panels are light enough to shift or become airborne due to wind
uplift on the panels.
Based on our conversations between David Lyle at DG Building Works, Rob Verreault of Therma-Hexx, and
Will Bod mer of Turner Morris, it has been determined that the most cost-efficient anchor system without
adding additional weight to the roof is to anchor the Therma-Hexx panels aga inst wind uplift with straps of
Thermoplastic Polyolefin (TPO) roof membrane hot air welded to the existing TPO membrane.
Based on information conveyed to us from Will Bodner of Turner Morris, we assume that the existing roof
membrane is a 60 mil TPO membrane designed to meet the minimum code requirement of 90 psf uplift on
the structural substrate, that both new and existing membranes meet the minimum strength requirements
of ASTM D6878 using the test methods of ASTM D751, and that the hot air welding creates a bond equal to
the strength of the membrane itself. We assume that the existing roof membrane is in good condition and
has not been damaged and that the structural substrate is in good condition and has not experienced past
water damage that may reduce the uplift capacity.

• To not exceed the minimum strength of the existing TPO roof membrane and roof substrate, the
new TPO straps should be spaced no more than 6 feet apart or every (3) 2'x2' panels in a line. The
straps of one line shall alternate with the straps in the adjacent line of panels.
• Each new TPO strap shall be a minimum of 60 mil thickness, at least 4" wide, and shall be hot air
welded to the existing membrane with a minimum contact area of 4"x4".
• All panels within 4'-0" of a roof edge shall be strapped down.
attachment to the substrate as described above. Water damage or inadequate design may reduce the
strength of the roof system. The analysis is based on assumed values for existing roof composition,
membrane thickness and strength. Martin/Martin recommends a strength evaluation of the proposed
system or "pull test" to ensure adequate strength of both the proposed system and the existing roof system.
Martin/Martin has not observed the roof membrane or substrate for defects or damage and does not accept
responsibility for structural or material deficiencies of the roof.
Please feel free to call if you have any questions.
Sincerely,
Sean Molloy, PE

A Valuable Component to Your Roof System
The addition of lnvinsa® or lnvinsa® FR Roof Board to a single ply or
SBS roof system increases the roof's resistance to damage from various
sources. including but not limited to hail. foot traffic. construction loads
and normal roof maintenance. lnvinsa is engineered as an integral part
of the roof system, providing a protective layer for the insulation below
and working with the membrane above to improve performance. lnvinsa
may be specified for new. re-roof and re-cover applications.
Product Advantages
• High resistance to indentation. compression and crushing during
installation of the roof system and during periodic maintenance,
once the roof is completed
• Rigidity to support the roof membrane
• Increased resistance to moisture absorption
• Dimensional stability
• Compatibility with PVC, TPO, EPDM and SBS roofing systems
• UL®. FM Global® and other important building agency approvals

Vail, CO -DoubleTree Hotel -Roof Snowmelt System
Below is a detailed response to the questions raised by the Town of Vail's Building Department.
1. The section detail on sheet 2 calls for a "protective sheet " . Please provide details. The
DRB approval did not approve a protective sheet over the panels.
We are not using a protective sheet. Detail is updated.
2. The Therma Panel published specifications call for a drainage mat under the panels on a
Solid roof assembly. The project Engineers need to review the roof drainage in relation to the
panels and existing roof drains and provide drainage specifications as required.
That detail is obsolete. Our panels will sit directly on the existing TPO membrane and conform
to the same pitch as the roof. Our panels are spaced in a manner that will allow water to flow
to the drains without obstruction. Our panel rows are spaced 1.25" in between the rows. The
panels in the row are spaced 3/4". This will allow water to flow freely past the panels in all
directions and flow to the drains. Specialized trimmable panels will be installed at drain
locations to allow for continued accessibility to the drains.
3. The panel layout on sheet 1 needs to indicate the location of the proposed intermittent
pave rs.
This is obsolete. Drawing is updated.
4. The design wind load for the subject building is 11Smph. Please provide Engineered
details that support the proposed ballast plan with regard to the wind loads.
We have collaborated with a local engineer Sean Molloy of Martin/Martin and roofing
contractor Will Bod mer of Turner Morris to review the local wind up lift code. Together we
have come up with a method of securing the panels to the roof that will satisfy the wind uplift
code.
We will use 3" wide strips of TPO as strapping welded to the roof. The strapping will span across
the center of the panel to secure the panel to the roof.

THERmA-HEXX®
The following information was used for the calculations against roof uplift:
• Based on Town of Vail wind loads, the uplift on the rooftop panels is 14 psf.
• The Therma-hexx panels weigh 1.6 psf which is an acceptable increase in weight
considering the benefit of removing snow without exposing snow removal personnel to
the hazard of removing snow from the roof.
• Based on information from Will Bod mer of Turner Morris, the best estimate of the
existing roof is that it is a 60 mil TPO membrane with an anchorage pattern to the roof
substrate which provides 90 psf of uplift capacity.
• We assume that both the new and existing membranes meet the minimum strength
requirements of ASTM D6878 using the test methods of ASTM D751, and that the hot
air welding creates a bond equal to the strength of the membrane itself.
o This results in a minimum breaking strength of 55 pounds per inch of TPO
membrane.
o The tearing strength of a factory seam results in 33 pounds per inch. This may
be a more accurate representation of the strength of the welded joint and is
used below.
o Data for tearing of the membrane joint in a perpendicular direction was not
available.
o Data for the capacity of hot air welded joints was not available.
• We assume that the existing roof membrane is in good condition and has not been
damaged and that the structural substrate is in good condition and has not experienced
past water damage that may reduce the uplift capacity.
Based on these assumptions, we calculated the following:
• Based on an existing connection of the membrane to the substrate with a capacity of 90
psf, we can distribute load from 6 square feet of panel into a one square foot area {90 I
14 = 6.4). For 2 ft wide panels, this translates to holding down every 3 panels (6.4 I 2 =
3.2).
• To reduce the load in any one area, the straps should be staggered in adjacent rows of
panels.
• The uplift on 3 panels will be 168 pounds (3 panels x 2 ft x 2 ft x 14 psf = 168 #)
• For a tearing strength of 33 pounds per inch of width, 3" wide strips of TPO membrane
are required to hold down every third panel. {168 I (33 x 2 sides)= 2.6)
• Although not required by the code for uplift on rooftop equipment, other sections of
the building code require higher uplift loads at corners and edges of roofs. Therefore,
we would recommend that the first three rows of panels from any edge be strapped at
every panel.

Dear property owner,
As the owner of a Therma-HEXX ThermaPANEL (PANELS) heat exchange system, you play an important
role in ensuring proper operation over the lifetime of the system and ensuring that Therma-HEXX's limited
warranty remains in effect. We recommend that you adhere to the following guidelines:
• Consult with a licensed professional contractor to develop the appropriate inspection and
maintenance schedule for your system.
• Perform visual inspection, at least annually, of all accessible system components to ensure
products and fluids are functioning as intended .
• Do not modify or alter the PANEL or piping system. Only a licensed professional contractor who is
familiar with its operation should service or alter the system.
• Follow all manufacturer recommendations for service and operation.
• Do not expose Therma-HEXX products to harmful chemicals, oil or petroleum products, paint,
adhesives , solvents, household cleaners or aggressive water.
• Ensure that Therma-HEXX piping , fittings and PANEL units are concealed or insulated to protect
them from exposure to long term UV radiation from sunlight or artificial sources.
• Do not expose the PANEL and piping system to freezing or overheating conditions unless the
system was specifically designed to perform within certain seasonal temperature ranges . If the
system will remain inoperative for a period of time, or be exposed to conditions that are outside of
the design limits, arrange for the proper winterization or summerization of the system by a licensed
professional contractor.
• An adequately sized expansion tank and pressure relief valve that is sized to meet the specification
of the PANELS and piping must be installed in the system to prevent over pressurization of the
system due to overheated fluids. It is recommended that an automatic glycol feeder be installed in
closed loop systems that are subject to freezing conditions to keep the system pressurized to the
recommended system pressure and to compensate for pressure loss due to minor leaks and
evaporation in the system.
• For heating and geothermal applications, if freezing conditions are likely to occur, then a freeze
protection fluid must be used.
• Do not allow the system to be exposed to temperatures and I or pressures outside of the limits as
specified for the PANEL units or piping.
• Use caution when drilling or nailing into the area where the ThermaPANEL units or tubing are
installed. Identify the location of the PANELS and pipe to ensure that nails or screws do not
puncture the Panels or pipe.
• Use caution when digging in the vicinity of the PANELS, pipe or manifolds as you would with any
buried utility system .

PART 3 EXECUTION
3.1 EXAMINATION
A. Do not begin installation until substrates have been properly prepared.
B. If substrate preparation is the responsibility of another installer and is inadequate, notify
Architect of unsatisfactory preparation before proceeding.
3.2 PREPARATION
A. Clean substrate surfaces thoroughly prior to installation to eliminate any objects that could
interfere with the Panel system or puncture the panel system.
B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best
result for the substrate under the project conditions.
3.3 INSTALLATION
A. Install in accordance with manufacturer's instructions and approved shop drawings.
B. For pedestal mounted systems, the recommended sequence of installation for the Panel system is
to locate and install the manifolds and send and return piping, PRESSURE TEST TO MANUFACTURERS
SPECIFICATIONS. Once a manifold is installed and connected to the main supply and return piping,
isolate the expansion tank by closing the shut off valve to it, and pressure test the manifold and main
piping system to 30 psi prior to the installation of the heat exchange panels. Pressure test the expansion
tank to make sure that it is sealed and at the proper pressure for the system to the manufacturers
specifications. Open the system valve to the expansion tank after it passes the pressure test.
Once the main send and return system passes the pressure test, set the system pressure to the
maximum pressure marked on the heat exchange Panels. As each row of Panels is installed, it should be
hooked up to the manifold and pressurized. While the next row of panels is prepared, the paver/
pedestal installer shall set the pavers and prepare the next row of pedestals. As each zone is completed,
move to the next manifold and follow the same procedure until all Panels are installed. Pavers or finish
surface should be installed as soon after pressurization as possible. Whenever possible, keep Panels
pressurized during installation of Pavers or finish surfaces. When pressurizing with air, some fluctuation
of pressure (approximately+/-10%) is normal as the Panels will expand when placed under pressure.
C. Installation training videos are available at www.therma-hexx.com
D. Fill the system with water, pressure test to the stated maximum pressure as marked on the Panels
and purge before filling with glycol mixture. Make sure that the expansion tank is NOT isolated from the
system. After successfully testing with water, blow the water out of system with compressed air and
replace with the appropriate glycol mixture.
E. Never keep the system isolated from the expansion tank when fluids are in the system. Over
expansion of the Panels and bursting can occur on warm days when the fluid will expand in the system.
F. For ground mounted systems, apply 1 inch of bedding sand or stone dust to the top of the modular
heat exchange panels making sure to fill the gaps between the Panels with sand, screed the sand to the
appropriate thickness and level, apply the paver or stone surface and tamp the units to provide an even
surface to within .125 inch between the paver units. Apply polymeric sand to manufacturer
specifications using a plate vibrator I compactor us ing a sheet of plywood between the plate compactor
and the paver surface to protect the paver surface from marring.
G. Route piping in an orderly manner, as designated by the manufacturer or architect I engineer on
approved shop drawings. Changes to routing as specified on shop drawings must be approved by the
manufacturer. The installing contractor shall document the as built installation.
H. When called out on Drawings, Panels may be trimmed or cut as required only in the direction of the
Panel flow up to a minimum width of 8". Panels may be cut with any jigsaw, table saw or hand-held
power saw or sheet metal shear, using cutting blades appropriate for plastic, wood or metal. Do not cut
pressurized Panels. Complexity of the required cut will dictate the appropriate cutting tool. Panel cuts
will expose internal fluid distributing channels. Take appropriate steps to ensure fluid channels are not
contaminated with foreign materials and debris while exposed. Panel cutting should only be performed
by installers who have had proper instruction from the Panel manufacturer. Trimmed or cut Panels must
be resealed using the appropriate tools and technique as made available by the Panel manufacturer.
Following the cutting or trimming of any Panels, the sealed off openings shall be tested with soapy
water to verify resealing integrity.
I. Install piping to allow for expansion and contraction without stressing pipe, joints, or connected
equipment.
J. Where Panels are installed over roof drains, manifolds or other objects that require access or
inspection, the installing contractor shall provide a minimum of a 4 foot loop of Yi" PE-RT connecting
tubes between Panels, on the inlet and outlet of the Panel, located directly above the roof drain to allow
for the temporary displacement of the panel to allow for future maintenance of the roof drains without
the need to disconnect the Panels. Connecting loops can be welded with standard PE-4710 -Yi" CTS
socket fusion fittings (to be provided by Manufacturer).
K. Maintain clearance for access to valves and fittings.
L. Air elimination is essential for proper operation of the Panel system. Installer shall be responsible to
ensure proper installation of air elimination devices. Coalescing type air separation units are
recommended.
M. Verify pumps operate at specified system fluid temperatures without vapor binding and
cavitation, are non-overloading in parallel or individual operation, and operate within 25 percent of
midpoint of published maximum efficiency curve.
N. If required, install a line sized shut-off valve and strainer on pump suction, and line sized check
valve and balancing valve on pump discharge. Install air vent and drain connection on horizontal pump
casings. Install a swing check valve on the return side of each manifold and spring type in line check
valves (set above the static system pressure) on the send side of each manifold if the main system is
located above the Panels elevation to prevent draining of the system glycol should a leak occur. An
adjustable pressure reducing valve (PRV) should be installed on the inlet side of each manifold if the
system operating pressure will exceed the maximum Panel pressure to allow for system head pressure
requirements.
0. Install unions downstream of valves and at equipment or apparatus connections.
P. Install electrical devices furnished loose for field mounting.
Q. Install control wiring between control panel and field mounted control devices.
R. System control concept. This system is designed to facilitate snow and ice removal from designated
paver areas in winter months. Coverage areas are defined within the projects drawing package. In
summer months, the system is designed to collect & remove solar generated surface heat from the
same areas and to distribute the collected energy to a designated place should one be provided.
S. System control sequencing -Snow and Ice Removal Mode. The system shall be controlled by a
dedicated Snow and Ice Melting control, as designated and supplied by the Manufacturer. Key
components shall consist of Controller, Snow & Ice Melting Sensor and in-paver temperature sensor.
Sensor shall be surface mounted, located within the paver system in an area which is deemed the most
critical for snow and ice removal. Paver installer shall be responsible for making provisions for the
installation of sensors and in-paver temperature sensor. The controller shall be programmed by the
system installer to meet the requirements of the owner.
T. System control sequencing -Heat transferring Mode. The system shall be controlled by a
differential controller, as designated and supplied by the Control Manufacturer.
U. Connect the system to power source as specified in Section 16150.
V. Once the entire system is piped and deemed leak-free, fill and purge the system as needed for
normal operation. Fill each Panel row separately to ensure complete removal of air as well as
completely filling with mixed antifreeze solution.
W. Install an automatic glycol injection and pressurization system set to a maximum of 14psi with a
minimum of a 17 gallon tank capacity or appropriate size for the size of system to allow for over
pressurization outflow collection and system pressurization maintenance. A low pressure shut off
switch set to 10 psi shall be installed to shut down the pump(s) should the glycol feeder run out fluid
and cease to pressurize the system . The system requires a circulating fluid that contains antifreeze.
Installer shall be responsible for determining exact concentration required, depending upon location
and operating conditions. Follow the recommendations of the antifreeze manufacturer and consider
operating conditions, health and safety requirements before choosing and installing antifreeze. It is
recommended that the solution be premixed prior to installation to ensure proper mixing and
concentration level. Installer shall be responsible to check final concentration following installation.
Antifreeze concentration diminishes over time. Follow the manufacturer's recommendations for testing
and monitoring of concentration levels.
X. Install an adequate sized air elimination un it and expansion tank. Note that each Panel and its
interconnecting tubes hold 0.26 - .36 gallons of fluid.
Y. The snow melt control system shall be designed with one or more zones capable of both moisture
and temperature sensing. Locate sensors to monitor the most critical pedestrian areas under control.
All zones shall be operated simultaneously when prompted by the control system. Warm weather
operation is intended to remove excess heat from pavers and redistribute this heat into the fountain
water. Seasonal operation shall be controlled by a manually operated three-way value and in-line
temperature gauge. Building maintenance staff shall be instructed on recommended process for
seasonal change-over and for ongoing temperature monitoring.
Z. Provide acceptance testing of all components and maintain a written record of the results of all
acceptance tests.
