Box 7000 | Carlisle, PA 17013 | Fax: 717-245-7053 | www.carlislesyntec.com EXPERIENCE THE CARLISLE DIFFERENCE Reinforced Membrane Overview Carlisle’s Sure-Weld TPO reinforced membrane is a premium, heat- weldable, single-ply thermoplastic polyoleﬁn (TPO) sheet designed for new roof construction and re-rooﬁng applications. Sure-Weld High Slope (HS) membrane is formulated with additional ﬂame retardant for higher-slope ﬁre code approvals. Sure-Weld EXTRA is 80 mils thick for signiﬁ cantly higher strength and weatherability. Sure-Weld TPO membranes use advanced polymerization technology that combines the ﬂexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. All Sure-Weld TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package. OctaGuard XT technology enables Sure-Weld 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. Carlisle’s standard and HS TPO membranes are available in highly reﬂective white, tan, and gray, in both 45-mil and 60-mil thicknesses. 80-mil Sure-Weld EXTRA (including HS) is also offered in white, gray, and tan colors. Special color Sure-Weld HS TPO membranes are also available (see Carlisle’s TPO Color Palette brochure). Carlisle’s TPO is offered in 4-, and 6-ft perimeter sheets and 8-, 10-, and 12-ft Sure-Weld ﬁ eld sheets. Sure-Weld HS and special color TPO membranes are available in limited sizes. Carlisle’s tan and white TPO membranes are ENERGY STAR®*-qualiﬁed and California Title 24 compliant and can contribute toward LEED® (Leadership in Energy and Environmental Design) credits.

Durable and easy to remove, APEEL Protective Film improves aesthetics and long-term reﬂ ectivity and is ideal for re-rooﬁ ng, re-cover, and new construction projects. EXPERIENCE THE CARLISLE DIFFERENCE Reinforced Membrane Installation 1. Sure-Weld 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. 2. 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. When the installation of the entire TPO rooﬁ ng system is complete, remove and discard the APEEL Protective Film. 3. The Carlisle Mechanically Fastened Roof System installation starts by fastening the insulation with a minimum of 4 fasteners per 4' by 8' board. The membrane is mechanically fastened to the deck using HP-X™ Fasteners and Piranha Plates™ or HP-XTRA Fasteners and Piranha XTRA Plates. Adjoining sheets of membrane are overlapped over the fasteners and plates and joined together with a minimum 1½"-wide (4 cm) hot-air weld.

The Carlisle Fully Adhered Rooﬁng System installation begins by fastening the insulation at the required density necessary to meet the appropriate warranty or wind load requirement. The substrate and membrane are then coated with an appropriate Sure-Weld TPO bonding adhesive and the membrane is rolled into place. Review Carlisle speciﬁ cations and details for complete installation information. 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 ﬁ lm away from the membrane prior to cutting. »Remove APEEL Protective Film by pulling towards the center of the roof. Do not remove the ﬁ lm 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 ﬂ ammable products and a ﬁ re 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 speciﬁ cation for Thermoplastic Polyoleﬁn-Based Sheet Rooﬁ ng. 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.” Carlisle’s goal is to produce TPO that delivers maximum performance for the intended purpose of rooﬁ ng 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 rooﬁ ng materials. Carlisle Testing – Heat Aging ASTM Requirement Sure-Weld 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" piece of 45-mil membrane unbacked, placed in circulating hot-air oven. »Criterion – no visible cracks after bending aged test specimen around 3"-diameter mandrel. Q-Trac testing combines accelerated weathering with real-world conditions using an array of ten mirrors to reﬂ ect 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. Carlisle requires its Sure-Weld TPO membranes to pass the equivalent of 40 years of exposure in the Q-Trac.
