VersiWeld High Slope (HS) membrane is formulated with additional flame retardant for higher- slope fire code approvals. VersiWeld Plus is 80 mils (2.03 mm) thick for significantly higher strength and weatherability. VersiWeld TPO membranes use advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. All VersiWeld TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package. OctaGuard XT technology enables VersiWeld 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 •VersiWeld TPO available in 4-, and 6-ft (121.92 cm and 182.88 cm) perimeter sheets and 8-, 10-, and 12-ft (243.84 cm, 304.80 cm, and 365.76 cm) VersiWeld field sheets* •Outstanding puncture resistance BUILDING VALUE TECHNICAL DATA BULLETIN White Slate Gray Gray Med Bronze Tan Terra Cotta Patina Green Rock Brown ALL WORK SUBJECT TO FIELD INSPECTION Installation VersiWeld 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 VersiWeld TPO Reinforced Membrane TECHNICAL DATA BULLETIN 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 VERSICO SPECIFICATIONS AND DETAILS 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. •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. •Exercise caution when walking on wet membrane. Membranes may be slippery when wet. •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. BUILDING VALUE Optional APEEL™ Protective Film: Shield Versico’s VersiWeld TPO membrane from dirt and scuffs during installation with APEEL Protective Film. Durable and easy to remove, APEEL eliminates the need for rooftop cleaning upon project completion. •Ideal for re-roofing, re-cover, and new construction projects •Simple and easy to remove •Saves time and money when compared to pressure washing •Protecting from dirt maintains maximum membrane reflectivity and long-term performance Installation Simply order membrane with APEEL, install, and remove the film to reveal a clean, new roof. •APEEL Protective Film should be removed from within areas that are to be heat-welded together. In areas that do not require heat-welding, the APEEL Protective Film can be left in place for up to 90 days without degrading due to its excellent heat- and UV-resistance . •When the installation of the entire TPO roofing system is complete, remove and discard the APEEL Protective Film. 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.” Versico’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. Versico Testing – Heat Aging ASTM Requirement VersiWeld 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. Versico requires its VersiWeld TPO membranes to pass the equivalent of 40 years of exposure in the Q-Trac. Versico Testing – Q-TRAC ASTM D6878 Requirement VersiWeld Requirements ASTM Test N/A N/A Equivalent of 40 years of exposure VersiWeld TPO Reinforced Membrane TECHNICAL DATA BULLETIN Environmental Cycling subjects the membrane to repeated cycles of heat aging, hot-water immersion, and xenon-arc exposure. •ASTM requirement – none •Versico 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.

The SRI is a measure of the roof’s ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. Materials with the highest SRI values are the coolest choices for roofing. Due to the way SRI is defined, particularly hot materials can even take slightly negative values and particularly cool materials can even exceed 100.
