2 Defy the Elements Invinsa Lightweight, Impact-Resistant Roof Board Impact Resistance: The Real Key. A properly installed roof system should stand up to the elements for many years. As with many roofs, there is one force that s harder to protect against, and that is damage from sudden impact the kind of impact, for example, that happens during a hail storm. Hail will easily dent the metal body of your car. In minutes, it will strip trees of their leaves, shred landscaping, attack anything left unprotected. Think of the pummeling a roof takes. This driving force can compromise the integrity and performance of the entire system, especially if the material beneath the membrane is fragile or subject to cracking, cratering or shattering upon impact. When a cover board is incorporated into the roofing assembly, it helps mitigate damaging impacts. But it is important to choose carefully or the cover board may actually make a roof assembly more vulnerable to fracture and cracking. A cover board with high compressive strength is not necessarily the entire answer; its resiliency also plays a key role. True impact protection is the result of achieving the right balance between compressive and flexural strength. In the drive to make roofs last longer and provide better protection, Johns Manville has mastered the science of integrating roofing system components and has developed a cover board material unlike any other. Invinsa Roof Board helps dissipate the damaging energy from hail and dropped tools. It enhances the compression resistance of the roofing system to typical foot traffic and roof traffic including loaded carts and equipment. Invinsa is a true protector of your valuable roof system. Add Protection Without Adding Too Much Weight or Cost With Invinsa. Architects, specifiers and contractors generally agree that adding a cover board enhances the long-term performance of single ply as well as cold-applied and selfadhered bituminous roof systems. It adds stability. It adds peace of mind. It adds a layer of protection between your thermal investment and the waterproofing membrane. Until now, some professionals have questioned just how much protection is actually offered by a cover board and whether that protection is worth it. Now the answer is a definite Yes! A Trusted Roofing Material in a Revolutionary New Form. Johns Manville has taken 20 years of history and expertise in polyisocyanurate manufacturing and has developed a revolutionary new product based on this technology. Invinsa meets or exceeds all ASTM C 1289, Type II, Class 4 standards. Invinsa Roof Board specifically meets the needs of cold-applied and self-adhering bituminous as well as single ply roofing systems. Its closed-cell formulation introduces a new level of roof system protection and performance. Invinsa absorbs impact energy better than many other cover board materials. It protects the insulation below while adding stability to the membrane above. It is one-third the weight of gypsum cover board materials, easing concerns about overall roof weight and making installation dramatically easier and less costly. With its mineral-coated fiber glass reinforced facers, Invinsa provides excellent water resistance. And it needs no priming. In re-roofing applications, Invinsa s light weight can actually mean the difference between a costly tear-off and replacement of the insulation versus a re-cover of existing materials, often resulting in significant savings. 2

3 Invinsa s extremely low water absorption (a maximum of 2.0% by weight when tested according to ASTM C 209) means fewer weather concerns during staging. Invinsa will not rot. It will not dissolve. It will not support mold. What it will do is maintain its integrity under adverse weather conditions for the long-term enhancement of the roof system. JM Invinsa Roof Board has been tested with and is approved by FM Global * and UL ** for use in certain Class A applications. System approvals include JM PVC, JM TPO and JM EPDM single ply systems, as well as cold-applied and self-adhering bituminous systems. Powerful, pounding, damaging. Hail is a driving force to a roof system. As the intensity of a storm and the size of the hail increase, the destructive energy hitting the roof expands. Where does it go? With Invinsa Roof Board as a protective layer between the membrane and the insulation, the system works in concert to maximize energy absorption, lessening the blow to the thermal layer. Imagine that same roof without a resilient layer of protection. And think of the dollars required for roof repair and replacement. Invinsa Roof Board optimizes the long-term performance and longevity of the entire roof system. Invinsa adds a stabilizing component to the roof system, providing long-term durability. Invinsa works with fully adhered and mechanically fastened JM PVC, JM TPO and JM EPDM systems, as well as cold-applied and selfadhering bituminous systems to meet certain FM Global 1A-90 roof constructions. Invinsa Defies the Human Element. Other forces are at work on the roof, as well. Foot traffic, dropped hammers and tools, heavily loaded carts. Invinsa s superior flexibility and resiliency defy the human elements to enhance the life of your roof system. Invinsa Defies All Preconceived Ideas About the Cost of Installation. A 4-foot x 8-foot (1.22 m x 2.44 m) sheet of Invinsa weighs only 12 pounds (5.4 kg). That s about one-third the weight of other gypsum cover boards. This obvious benefit, combined with the additional advantages of Invinsa, generates a whole host of installation cost savings. Reduced crane time, and lower hoisting and staging costs Easier to carry and maneuver around the roof Decreased weather damage during staging Reduced breakage and need for re-work and repair Less scrap and less waste removal compared to heavier, more brittle boards Easy and efficient scoring, cutting and snapping, which permits fast, tight fabrication around roof penetrations Efficient adhesive application due to smooth surface and low dust No priming necessary Ergonomic. Fewer possibilities for fatigue-related mistakes and injuries Faster turnaround of the entire job No longer is there any question of whether the costs of cover board outweigh the benefits. Now that you have a proven roofing material that can increase a roof s ability to resist fracture from impact, as well as lower the total cost of installation, you can do what you set out to do provide superior roofing systems to your valued clients.
