Sure-WeldTPO <br />Reinforced Membrane <br />4. The Carlisle Fully Adhered Roofing System installation begins by <br />fastening the insulation at the required density necessary to meet <br />the appropriate warranty or wind load requirement. The substrate <br />and membrane are then coated with an appropriate Sure -Weld TPO <br />bonding adhesive and the membrane is rolled into place. <br />Review Carlisle specifications and details for complete installation <br />information. <br />>� Sunglasses that filter out ultraviolet light are strongly recommended, as <br />tan and white surfaces are highly reflective. Roofing technicians should <br />dress appropriately and wear sunscreen. <br />>� Surfaces may become slippery due to frost and ice buildup. Exercise <br />caution during cold conditions to prevent falls. <br />» Care must be exercised when working close to a roof edge when <br />the surrounding area is snow-covered, as the roof edge may not be <br />clearly visible. <br />�> Use proper stacking procedures to ensure sufficient stability of the rolls. <br />» Exercise caution when walking on wet membrane. Membranes may be <br />slippery when wet. <br />» Store membrane in the original undisturbed plastic wrap in a cool, <br />shaded area and cover with light-colored, breathable, waterproof <br />tarpaulins. Membrane that has been exposed to the weather must be <br />prepared with Weathered Membrane Cleaner prior to hot-air welding. <br />>� Take care not to stand or place heavy objects on the edge of folded - <br />over membrane, as this could cause a hard crease in the membrane. <br />» Maximum sustained temperature not to exceed 160°F (71 °C) for TPO <br />membrane. <br />» Do not use razor blades or other sharp tools to cut the APEEL Protective <br />Film while it is still adhered to the TPO membrane as damage to the <br />underlying membrane may occur. Pull the protective film away from the <br />membrane prior to cutting. <br />» Remove APEEL Protective Film by pulling towards the center of the <br />roof. Do not remove the fllm by pulling towards the roof edge. <br />» A static electric charge may develop when removing APEEL Protective <br />Film from the surface of the membrane sheet. To avoid the possibility <br />of ignition, lids must be closed on any flammable products and a fire <br />extinguisher should be readily available. <br />>> Color membranes will 'fade' over time mainly due to the ultraviolet <br />portion of sunlight. Since most roof surfaces are exposed to variable <br />sunlight, some areas will be more susceptible to color changes caused by <br />UV fading. Warranties for color membranes do not cover fading of colors. <br />in � w�"ia i 7 npiuimnUiy �uiiull ll Nui Nuuuuu>� a/ Im. /�0 <br />ll r, /��. f„tA�^f1�„�n, anrt/I iuiyum 1l�rri�fffi <br />EXTREMETesting for Severe Climates <br />ASTM Standard D6878 is the material specification for Thermoplastic <br />Polyolefin-Based Sheet Roofing. It covers material property requirements <br />for TPO roof sheeting and includes initial and aged properties after heat <br />and xenon -arc exposure. As stated in the scope of the standard, "the tests <br />and property limits used to characterize the sheet are values intended to <br />ensure minimum quality for the intended purpose." Carlisle's goal is to <br />produce TPO that delivers maximum performance for the intended purpose <br />of roofing membranes. Maximum performance requires the membrane to <br />far exceed the requirements of ASTM D6878. <br />Heat Aging accelerates the oxidation rate that roughly doubles for each <br />18°F (10°C) increase in roof membrane temperature. Oxidation (reaction <br />with oxygen) is one of the primary chemical degradation mechanisms of <br />roofing materials. <br />ASTM Requirement Sure -Weld Requirement <br />ASTM TEST 32 weeks** >128 weeks <br />240°F <br />**Heat exposure comparable to 3,120 weeks (60 years) at 185°F for 8 hours/day. <br />Test specimen is a 2" by 6" piece of 45-mil membrane unbacked, <br />placed in circulating hot-air oven. <br />D> Criterion — no visible cracks after bending aged test specimen around <br />Y-diameter mandrel. <br />Q-Trac testing combines accelerated weathering with real -world conditions <br />using an array of ten mirrors to reflect and concentrate full spectrum <br />sunlight onto membrane test specimens. The 0-Trac device automatically <br />tracks the sun's path from morning to night. Also, it adjusts to compensate <br />for seasonal changes in the sun's altitude. Eight years in 0-Trac testing is <br />equal to 40 years of real -world exposure. Carlisle requires its Sure -Weld <br />TPO membranes to pass the equivalent of 40 years of exposure in the 0-Trac. <br />ASTM D6878 Requirement Sure -Weld Requirement <br />ASTM TEST WA Equivalent of 40 years <br />N/A of exposure <br />Environmental Cycling subjects the membrane to repeated cycles of heat <br />aging, hot-water immersion, and xenon -arc exposure. <br />» ASTM requirement —none <br />b> Carlisle EXTREME test": <br />- 10 days heat aging at 240°F (116°C) followed by <br />800-479-6832 1 P.O.
