  • 9. 3” LIGHTGUARD© Durham Detention Center, Durham, NC
  • 10. PROTECTED MEMBRANE ROOF An Idea Waiting to Happen After Dow invented an insulation durable enough to withstand exposure to the environment, the “upside down” concept needed a hard surface that still could give: Excellent moisture resistance Membrane protection capability Superior long-term R-value (against weathering, physical abuse, and hail damage) Exceptional durability, which Ability to maintain the membrane extends the life of the roof at a relatively constant or plaza temperature
  • 11. PROTECTED MEMBRANE ROOF TCLEAR Benefits LIGHTGUARD© helps to © maintain the roof membrane at a relatively constant temperature, minimizing stress from freeze-thaw cycling and excessive heat The blue area represents the relatively constant temperature of a protected membrane. The yellow area represents the temperature fluctuation of a conventional roof’s membrane.
  • 12. PROTECTED MEMBRANE ROOF TCLEAR Benefits LIGHTGUARD© protects the roof membrane from weathering, damage, foot traffic and other physical abuse (both during and after construction). This allows year-round construction since roof is waterproofed first, then insulated. LIGHTGUARD© permits easy removal and re- installation of ballast and insulation (for repairs or additional construction)
  • 13. Durability! Don’t try this with a gravel ballasted roof.
  • 14. PROTECTED MEMBRANE ROOF TCLEAR Benefits LIGHTGUARD© Compatible with a wide range of ballast options and membrane types Provides excellent moisture resistance and stable long-term R-value Offers exceptional durability to extend life of plaza or roof Reduces repair expenditures
  • 15. CONVENTIONAL ROOF ASSEMBLY PROTECTED MEMBRANE ROOF Life Cycle Conventional roof: TCLEAR LIGHTGUARD©: Lasts approximately 10 years Lasts approximately 25 to 30 years or more Gravel Ballast may blow off or shift Reduces the frequency of High cost of tear-off tear-offs Costs related to disposal of Insulation can be reused, materials in landfill avoiding landfill fees and replacement product cost
  • 16. Duke University Hospital Heliport Roof, Durham, N.C
  • 17. Duke University Hospital’s commitment to go “green” in its 2007 heliport roof replacement project has won a national award for environmental stewardship and design excellence. The Washington, D.C.-based Center for Environmental Innovation in Roofing presented the award during the 2009 International Roofing Expo held Feb. 3-5 in Las Vegas. “Duke Medicine is striving to be environmentally responsible in the construction and operation of our facilities,” says Robert Guerry, director of Medical Center Engineering and Operations. “We hope the positive outcome of the heliport roof sets the stage for further success, as we plan future hospital facilities.” Center Executive Director Craig Silvertooth said the Duke Hospital roof project illustrates perfectly the intent of the center’s 2009 Excellence in Design awards program. “The environmental and economic benefit of forward-thinking roof design can be very significant, as demonstrated by the Duke Hospital project,” Silvertooth said. Go “Green”
  • 18. The numerous “green” outcomes of the Duke Hospital helipad project included: • 718 tons of solid construction waste diverted from the landfill (and $29,797 in landfill dumping fees were avoided). • 430 tons of roof ballast stone recycled in Duke Forest for road stabilization. • 2,120 miles of dump truck/landfill travel avoided (and 265 gallons of fuel spared), based on Waste Industries Inc. calculations. • 289,000 board feet of T.CLEAR LIGHTGUARD salvaged and preserved for future reuse; so far, four other Duke buildings have been re-roofed with the salvaged insulation. The helipad project reflects Duke’s commitment to vision and leadership in environmental stewardship and sustainability, and to go beyond compliance in pursuing sustainability, stewardship and resource conservation. Felix Markham of Medical Center Facilities Planning was the staff architect. Katherine Jordan was the LEED accredited professional with the Office of the Medical Center Architect. Tim Pennigar was Engineering & Operations project manager for the helipad roof.
  • 19. PROTECTED MEMBRANE ROOF TCLEAR is a Better Value A protected membrane roof is cost-effective because it performs year after year, contributing to the building’s overall sustainability by delaying tear-off. Longer life cycle more than makes up for initial construction cost – Deferring a roof replacement by 10 years can save hundreds of thousands of dollars Reduces annual maintenance costs because membrane is protected from physical and environmental abuse Insulation and ballast can be reused
  • 20. PROTECTED MEMBRANE ROOF Maintenance Costs In commercial roofing, maintenance costs can be significant if patching, cleaning or rejuvenating is required. TCLEAR systems have significantly lower maintenance costs than conventional low slope roofs. For example, the owner of a 50,000 ft2 (4,645 m2) PMR can reduce the maintenance costs from 3 percent of initial roof cost to 1 percent of initial roof cost, providing a significant cost savings. An investment in a LIGHTGUARD PMR is paid back in about 7 to 10 years, after which the savings in maintenance costs continue to help the operations budget.
  • 21. PROTECTED MEMBRANE ROOF M I C H I G A N S T A T E U N I V E R S I T Y The LIGHTGUARD© System at Work Michigan State University in East Lansing, Mich., is no stranger to the protected membrane roof. More than 160 campus buildings have a PMR In addition to day-to-day durability and thermal performance, T.Clear LIGHTGUARD© withstands the load demands on the PMR during renovation and expansion projects.
  • 22. PROTECTED MEMBRANE ROOF T H E C O N F E R E N C E C E N T E R The LIGHTGUARD© System at Work Located in downtown Salt Lake City, The Conference Center has a 70,000 ft2 (6,500 m2) rooftop meadow – a massive re-creation of the wild landscape of Utah. The vegetation provides an aesthetically pleasing location as well as contributes to the reduction of the “urban heat island” effect. STYROFOAM extruded polystyrene from Dow provides the water resistance and compressive strength necessary to support the roof’s heavy soil loads. Coupled with T.Clear LIGHTGUARD© , walk areas are protected from incidental traffic and use.

  • 24. PROTECTED MEMBRANE ROOF Sustainability in the Roofing Industry As concern grows over energy use and natural resources, building owners and occupants are asking for “green” or environmentally friendly buildings that offer long-term performance and efficiency without straining construction and operating budgets.
  • 25. PROTECTED MEMBRANE ROOF Sustainability in the Roofing Industry To contribute to sustainability, builders and architects are choosing LIGHTGUARD© & CTI Insulated Roofing Panels for PMR applications. Its long-term thermal performance curbs the drain on energy resources, and its durability and superior moisture resistance increases the building’s life cycle.
  • 26. PROTECTED MEMBRANE ROOF Sustainability Objective Objective: Reduce the total energy consumption of the building (life-cycle costing) PMR benefit: PMR performs year after year – and the more a roof can be kept in use, the more it contributes to the overall sustainability of the building by delaying the impact of eventual tear-off.
  • 27. PROTECTED MEMBRANE ROOF Sustainability Objective Objective: Reduce global warming impact from excessively using energy sources (reduce) PMR benefit: A PMR using a rigid, extruded polystyrene insulation, with one of the highest R-values per inch, will realize reductions in utility bills, year after year. By reducing HVAC loads, this will lower pollution emissions from burning fossil fuels.
  • 28. Sustainability Objective Objective: Reduce global warming impact by providing a sustainable and durable SOLAR Panel application Introducing LIGHTGUARD Solar

  • 30. PROTECTED MEMBRANE ROOF Q U E S T I O N S A B O U T P M R ? Has the Answers Q: Is a LIGHTGUARD PMR too expensive? © A: Actually, a LIGHTGUARD PMR saves money in the long run. © The building can be weatherproofed faster, allowing interior trades to start work quicker. The insulation is laid after the membrane – and can be laid in any weather. Greater quality control is possible, as the membrane can be inspected or flood-tested before insulating and ballasting. The overall labor costs and material costs are reduced compared to systems that require fiberboard and separate vapor retarder. Lower maintenance cost and longer roof life span offset the initial capital cost for a LIGHTGUARD PMR.©
  • 31. PROTECTED MEMBRANE ROOF Q U E S T I O N S A B O U T P M R ? Has the Answers Q: Will my LIGHTGUARD PMR roof blow off? © A: No, because pressure equalization offsets the effect of wind uplift. The integrity of the membrane is essential to prevent air infiltration under the membrane. In a lightweight PMR – with a loose applied membrane and covered with LIGHTGUARD or CTI Roof Insulation – external pressures due to wind are © mostly applied to the membrane. The membrane will withstand the National Building Code of Canada calculated pressure if it is properly attached to the deck. In the case of a loose-applied membrane, it is important to prevent any air infiltration underneath the membrane. When air infiltration is restricted, any movement of the membrane will create a vacuum that will neutralize the uplift forces and keep the membrane on the deck.

  • 34. PROTECTED MEMBRANE ROOF Q U E S T I O N S A B O U T P M R ? Has the Answers Q: Will my insulation get wet? A: The Styrofoam extruded polystyrene insulation used in LIGHTGUARD and © CTI Roof Panels has the lowest moisture absorption of any insulation in the marketplace today. All insulation can become saturated if a “diffusion closed” situation occurs. This happens when the insulation is sandwiched between the vapor barrier and the roof deck. Constant ponding can also lead to this condition. To avoid diffusion closed situations, provide for a good slope to drain in your roof design (a minimum of 1/4" slope per foot) and ensure impermeable roof coverings, such as pavers, are installed on pedestals, so that vapor can escape.
  • 35. PROTECTED MEMBRANE ROOF Q U E S T I O N S A B O U T P M R ? Has the Answers Q: Is it difficult to find a leak in a PMR system? A: In loose-laid membrane systems, it is true that water can enter the building far from the actual location of the leak. However, if the membrane is fully bonded to the deck, this water remains at the location of the leak. And in the case of a leak, the PMR is far easier to repair, because all of the original materials can be reused – an environmentally friendly feature that will save you thousands of dollars.
  • 36. PROTECTED MEMBRANE ROOF The Smart Choice A PMR assembly using LIGHTGUARD or CTI Insulated Roof © Panels is the preferred choice, whether you are an architect, builder or building owner. To sum up the primary benefits, T.CLEAR CORP PMR SYSTEM : Maintains membrane at a relatively constant temperature Protects membrane from weathering and physical abuse Allows year-round construction
