Up to 10% pre-consumer recycled content Fully recyclable when used in mechanically attached systems 3rd-party verified Environmental Product Declaration available NSF P151 certification for rainwater catchment** California Title 24 compliant*** Free of Living Building Challenge red list chemicals **White only, produced in Tooele, UT ***White and Tan only Overview WeatherBond’s TPO reinforced membrane is a premium, heat-weldable, single-ply thermoplastic polyolefin (TPO) sheet designed for new roof construction and re-roofing applications. WeatherBond High Slope (HS) membrane is formulated with additional flame retardant for higher-slope fire code approvals. WeatherBond’s 80-mil thick TPO offers significantly higher strength and weatherability. WeatherBond TPO membranes use advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. All WeatherBond TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package. OctaGuard XT technology enables WeatherBond TPO to withstand the extreme weatherability testing that is intended to simulate exposure to severe climates. Physical properties of the membrane are enhanced by a strong polyester fabric that is encapsulated between the TPO-based top and bottom plies. The combination of the fabric and TPO plies provides high breaking and tearing strength, as well as excellent puncture resistance. The relatively smooth surface of the membrane produces a total surface fusion weld that results in a consistent, watertight, monolithic roof assembly. The membrane is environmentally friendly and safe to install. Features and Benefits WeatherBond TPO is available in 4-, and 6-ft (121.92 cm and 182.88 cm) perimeter sheets and 8-, 10-, 12-, and 16-ft (243.84 cm, 304.80 cm, 365.76 cm, and 487.68 cm) WeatherBond field sheets* Outstanding puncture resistance Excellent fire resistant assemblies Environmentally friendly and stable formulation WeatherBond TPO Reinforced Membrane White Gray Tan Slate Gray Med Bronze Terra Cotta Patina Green Rock Brown Installation WeatherBond TPO roofing systems are quick to install, as minimal labor and few components are required. TPO systems are installed using an Automatic Heat Welder, making sheet welding fast, clean, consistent, and easy to learn, while reducing strain on the roofing technician. Fully-Adhered – membrane is adhered to a suitable substrate utilizing an appropriate bonding adhesive Mechanically Attached – membrane is attached to the roof deck over a suitable substrate utilizing plates and fasteners which are overlapped with membrane Induction-Welded – membrane is attached over a suitable substrate via an induction welding tool being placed over the membrane where a fastened TPO induction welding plate is located to weld the two components together REVIEW CURRENT WEATHERBOND INSTALLATION INSTRUCTIONS FOR SPECIFIC INSTALLATION REQUIREMENTS. Precautions Sunglasses that filter out ultraviolet light are strongly recommended, as tan and white surfaces are highly reflective. Roofing technicians should dress appropriately and wear sunscreen. Surfaces may become slippery due to frost and ice buildup. Exercise caution during cold conditions to prevent falls. Exercise caution when walking on wet membrane. Membranes may be slippery when wet. Care must be exercised when working close to a roof edge when the surrounding area is snow-covered, as the roof edge may not be clearly visible. Use proper stacking procedures to ensure sufficient stability of the rolls. Store membrane in the original undisturbed plastic wrap in a cool, shaded area and cover with light-colored, breathable, waterproof tarpaulins. Membrane that has been exposed to the weather must be prepared with Weathered Membrane Cleaner prior to hot-air welding. Take care not to stand or place heavy objects on the edge of folded-over membrane, as this could cause a hard crease in the membrane. Maximum sustained temperature not to exceed 160°F (71°C) for TPO membrane. Do not use razor blades or other sharp tools to cut the APEEL Protective Film while it is still adhered to the TPO membrane as damage to the underlying membrane may occur. Pull the protective film away from the membrane prior to cutting. Remove APEEL Protective Film by pulling towards the center of the roof. Do not remove the film by pulling towards the roof edge. A static electric charge may develop when removing APEEL Protective Film from the surface of the membrane sheet. To avoid the possibility of ignition, lids must be closed on any flammable products and a fire extinguisher should be readily available. Color membranes will ‘fade’ over time mainly due to the ultraviolet portion of sunlight. Since most roof surfaces are exposed to variable sunlight, some areas will be more susceptible to color changes caused by UV fading. Warranties for color membranes do not cover fading of colors. Extreme Testing for Severe Climates ASTM Standard D6878 is the material specification for Thermoplastic Polyolefin-Based Sheet Roofing. It covers material property requirements for TPO roof sheeting and includes initial and aged properties after heat and xenon-arc exposure. As stated in the scope of the standard, “the tests and property limits used to characterize the sheet are values intended to ensure minimum quality for the intended purpose.” WeatherBond’s goal is to produce TPO that delivers maximum performance for the intended purpose of roofing membranes. Maximum performance requires the membrane to far exceed the requirements of ASTM D6878. Heat Aging accelerates the oxidation rate that roughly doubles for each 18°F (10°C) increase in roof membrane temperature. Oxidation (reaction with oxygen) is one of the primary chemical degradation mechanisms of roofing materials. Single-Ply Simplified Wider is Better WeatherBond’s 16-foot TPO delivers a leap in productivity on adhered and induction welded roofs by cutting down on the number of rolls needed and dramatically reducing the number of seams on the roof. With fewer rolls to load, stage, and kick out, and fewer seams to weld, contractors can save significant time on each project, moving on to the next one sooner. 16-Foot TPO Benefits Fewer rolls to load and stage on a job saves crane time and labor at the beginning of each project Fewer rolls to position, kick-out, and align during installation saves labor Up to 60% fewer seams vs. 10-foot TPO Fewer seams to weld, probe, and inspect, saving considerable time during installation Fewer T-joint patches to install on each roof Less waste and trash from packaging Less time spent on each project, allowing contractors to complete more roofs and grow their business Single-Ply Simplified WeatherBond Testing – Heat Aging ASTM Requirement WeatherBond Requirement ASTM TEST 240°F 32 weeks**>128 weeks **Heat exposure comparable to 3,120 weeks (60 years) at 185°F for 8 hours/day. Test specimen is a 2" by 6" (50.8 mm by 152.4 mm) piece of 45-mil (1.14 mm) membrane unbacked, placed in circulating hot-air oven. Criterion – no visible cracks after bending aged test specimen around 3" (76.2 mm)-diameter mandrel. Q-Trac testing combines accelerated weathering with real-world conditions using an array of ten mirrors to reflect and concentrate full spectrum sunlight onto membrane test specimens. The Q-Trac device automatically tracks the sun’s path from morning to night. Also, it adjusts to compensate for seasonal changes in the sun’s altitude. Eight years in Q-Trac testing is equal to 40 years of real-world exposure. WeatherBond requires its TPO membranes to pass the equivalent of 40 years of exposure in the Q-Trac. WeatherBond Testing – Q-Trac ASTM D6878 Requirement WeatherBond Requirement ASTM TEST N/A N/A Equivalent of 40 years of exposure Environmental Cycling subjects the membrane to repeated cycles of heat aging, hot-water immersion, and xenon-arc exposure. ASTM requirement – none WeatherBond Extreme test*: –10 days heat aging at 240°F (116°C) followed by –5 days water immersion at 158°F (70°C) followed by –5,040 kJ/m² (2000 hours at 0.70 W/m² irradiance) xenon-arc exposure * Test specimen is 2.75" (69.85 mm by 140 mm) by 5.5" piece of membrane with edges sealed. * Criterion – after 3 complete cycles, test specimens shall remain flexible and not have any cracking under 10x magnification while wrapped around a 3" (76.2 mm)-diameter mandrel.

Manufacturer Georgia-Pacific Gypsum Georgia-Pacific Canada 133 Peachtree Street 2180 Meadowvale Boulevard, Suite 200 Atlanta, GA 30303 Mississauga, ON L5N 5S3 Technical Service Hotline: 1-800-225-6119 Description DensDeck® Prime Roof Board has been enhanced to provide a broader compatibility and higher performance with roofing adhesives. Face mat enhancements allow adhesives to be applied more uniformly and consistently. In adhered, single ply membrane testing, enhanced DensDeck Prime demonstrated an average of 24% better bond than the original products, when using solvent based adhesives. (Average based on 60 sq.ft./gal coverage rates.)* Choose DensDeck Prime Roof Boards for adhered and self-adhered “peel & stick” roofing systems, as well as hot mopped, cold mastic and torch-applied modified bitumen roofs. Enhanced DensDeck Prime Roof Boards create a stronger and more economical installation by reducing the amounts of mastic or adhesive used and potentially eliminates the field primer. Consult with membrane manufacturer for actual priming requirements. DensDeck Prime Roof Boards are the first and only fiberglass mat gypsum roof boards with a 90-day weather exposure limited warranty when applied vertically on a parapet wall.** (Limited to 1/2( and 5/8( products only.) Primary Uses Roof system manufacturers and designers have found DensDeck Prime Roof Board to be compatible with many types of roofing systems, including: modified asphalt, single-ply, metal systems, recover board, as well as an overlayment for polyisocyan- urate and polystyrene insulation. DensDeck Prime Roof Board can also be used as a form board for poured gypsum concrete deck in roof applications as well as a substrate for spray foam roofing systems. 1/2( (12.7 mm) and 5/8( (15.9 mm) DensDeck Prime Roof Board may also be used in vertical applications as a backer board or liner for the roof side of parapet walls. DensDeck Prime Roof Board may allow the bonding of cold mastic modified bitumen and torching directly to the surface. Consult with the system manufacturer for recommendations on this application. DensDeck Prime Roof Board is the preferred substrate for vapor retarders. Standards and Code Approvals DensDeck Prime Roof Boards are manufactured to meet ASTM C1177 and have the following approvals: • Florida Product Approved • Miami-Dade County Product Control Approved Recommendations and Limitations DensDeck Prime Roof Boards are manufactured to act with a properly designed roof system following good roofing practices. The actual use of DensDeck Prime Roof Board as a roofing component in any system or assembly is the responsibility of the roofing system’s design authority. Consult with the appropriate system manufacturer and/or design authority for system and assembly specifications and instructions on applying other products to DensDeck Prime Roof Board. Georgia-Pacific does not warrant and is not responsible for any systems or assemblies utilizing DensDeck Prime Roof Board or any component in such systems or assemblies other than DensDeck Prime Roof Board. The need for a separator sheet between the DensDeck Prime Roof Board and the roofing membrane must be determined by the roof membrane manufacturer or roofing system designer. Confirm any priming requirements with the membrane manufacturer. When applying solvent-based adhesives or primers, allow sufficient time for the solvent to flash off to avoid damage to roofing components. DensDeck Prime Roof Boards should not be subjected to abnormal or excessive loads or foot traffic, such as, but not limited to, use on plaza decks or under steel-wheeled equipment that may fracture or damage the panels. Provide suitable roofing system protection when required. When using DensDeck Prime Roof Boards for hot-mopped applications, Georgia-Pacific recommends maximum asphalt application temperatures of 425°F (218°C) to 450°F (232°C). Application temperatures above these recommended temperatures may adversely affect roof system performance. Consult and follow the roofing system manufacturer’s specifications for full mopping applications and temperature requirements. When using DensDeck Prime Roof Board as a substrate for torch applications, ensure that the product is dry and that the proper torching technique is used. Limit the heat to the DensDeck Prime Roof Board. Maintain a majority of the torch flame directly on the roll. Conditions beyond the control of Georgia-Pacific, such as weather conditions, dew, leaks, application temperatures and techniques may cause adverse effects with roofing systems. Handling and Use–CAUTION This product contains fiberglass facings which may cause skin irritation. Dust and fibers produced during the handling and installation of the product may cause skin, eye and respiratory tract irritation. Avoid breathing dust and mini- mize contact with skin and eyes. Wear long sleeve shirts, long pants and eye protection. Always maintain adequate ventilation. Use a dust mask or NIOSH/ MSHA approved respirator as appropriate in dusty or poorly ventilated areas. Moisture Management DensDeck Prime Roof Boards, like other components used in roofing systems, must be protected from exposure to moisture before, during and after installation. Remove the plastic packaging from all DensDeck Prime Roof Board immediately upon receipt of delivery. Failure to remove the plastic packaging may result in entrapment of condensation or moisture. DensDeck Prime Roof Board stored outside must be stored level and off the ground and protected by a breathable waterproof covering. Provide means for air circulation around and under stored bundles of DensDeck Prime Roof Board. DensDeck Prime Roof Board must be covered the same day as installed. Avoid application of DensDeck Prime Roof Boards during rain, heavy fog and any other conditions that may deposit moisture on the surface, and avoid the overuse of non-vented, direct-fired heaters during winter months. When roofing systems are installed on new poured concrete or light weight concrete decks or when re-roofing over an existing concrete deck, a vapor barrier should be installed above the concrete to retard the migration of water from the concrete into the roof assembly. Always consult the roofing system manufacturer or design authority for specific instructions for applying other products to DensDeck Prime Roof Boards. Moisture vapor movement by convection must be eliminated, and the flow of water by gravity through imperfections in the roof system must be controlled. After a leak has occurred, no condensation on the upper surface of the system should be tolerated, and the water introduced by the leak must be dissipated to the building interior in a minimum amount of time. Although DensDeck Prime Roof Boards are engineered with fiberglass facings and high density gypsum cores, the presence of free moisture can have a detrimental effect on the performance of the product and the installation of roofing membranes. For example, hot asphalt applications can blister; torched modified bitumen may not properly bond; and adhesives for single ply membranes may not dry properly.

Minimum Application Temperature 5 °C (41 °F) Complementary products EXTERIOR PRIMER OR H2O PRIMER Tools Required Knife Smoothing roller Tape measure Surface Preparation The substrate must be clean, dry and free of dust, grease or other contaminants. Installation Prerequisite The use of EXTERIOR PRIMER or H2O PRIMER is not required on most surfaces when the membrane is covered within 24 hours of installation. Installation 1. If conditions require, prepare the substrate with EXTERIOR PRIMER or H2O PRIMER. 2. Position the membrane parallel to the roof edge while leaving about 8 cm (3.2 in) at the front where the gutter will be installed. 3. Fold back on itself, by half of its width, or 50 cm (20 in) over the whole length already positioned. It is recommended to kneel on the unfolded portion of the membrane to keep it in place during this operation. 4. Remove the protective film from the folded section while placing the membrane on the support. The self-adhesive portion then adheres to the support. 5. Then take the other side of the membrane and repeat the previous two steps. 6. Immediately apply pressure on the membrane using a heavy metal roller or a hard rubber roller to ensure adhesion between the support and the membrane and avoid forming bulges, folds or gaps. Note: The transverse and longitudinal overlap should be 75 mm (3 in). Refer to ROOF SYSTEM INSTALLATION for waterproofing membrane installation to roof details and upstands. Recommendations/ Limitations It is not recommended to use a product containing bitumen directly on boards softwood or flexible polyvinyl chloride. Check that the membrane is not dusty, wet or frosted to maintain its slip resistance.
