Prepainted Galvalume sheet roof establishes strong focal point for recreation center. Vistana Resort, located in Orland, Florida near Disney World, is one of the nation's largest and most successful vacation ownership resorts. The Vistana Fountains Recreation Center was completed in 1990. It is one of four recreational facilites offering the Resort's vaction owners and rental guests a variety of activities, including swimming, outdoor hot tubs, volleyball, shuffleboard, a children's playground, a health/fitness area and a fitness room with exercise equipment. The design of the Center was influenced by Florida's historic cracker-style architecture, which made use of stucco walls and metal roofing. A design objective was to establish the Center's roof as a strong focal point in relation to the surrounding shingle-roofed structures in the complex. In addition, the roofing system had to fit within the allotted building budget. The metal roofing system selected not only statisfied the budget and aesthetics requirements, but it also reinforced the Center's location as the activities center for that area of the Resort. Design criteria: scale, color and durabilityScale was an important factor in the overall design of the project. Insofar as the roof was concerned, elevation drawings helped determine what the proper spacing and size of the seams should be for the architectural standing seam panels. The stucco-walled building is topped with an architectural standing seam roof manufactured by MBCI, Houston, TX. Approximately, 15,600 sq ft of MBCI's Craftsman Series SB12, 24-gage prepainted Galvalume sheet roofing panels finished in Duranar XL Copper Metallic were applied. The designer liked the Duranar paint system, not only for its color, but also for its guarantee against fade and good resistance to ultraviolet light. This was a primary concern because of the roof's heavy exposure to sunlight in this area. Resistance to moisture was also a concern. The combination of the Galvalume coating and the paint system provides extra protection against degradation of the panel due to moisture. MBCI's Craftsman Series SB12 panel system was installed over a 1-inch plywood deck and 30# felt paper. The architect and owner believe that the use of the extra thick 1-inch plywood backing results in a better looking roof because it provides more uniform support of the panel system. Wind was also a concernAlthough Vistana Resort is not located along the coast, high winds are still a major concern. The roofing system selected had to be able to withstand the 120 mph uplift rating of central Florida. MBCI's SB12 roofing has a UL90 rating which enables it to not only meet, but exceed the wind load requirement specified. Many color options availablePrepainted Galvalume sheet from Bethlehem is available in a wide variety of colors and finishes. Bethlehem's process specification program insures that the prepainted Galvalume sheet is produced to prescribed standards. The program specifies methods and materials to be used in each phase of the painting process. The painting process specification includes corrosion-resistant chemical pretreatments, specially formulated, high-performance primers and numerous durable, attractive finishes including polyesters, silicone polyesters and fluorocarbons. Each of the paint systems is formulated to provide superior long-term performance at sheared edges, as well as at flat, formed and paint-damaged areeas. Galvalume sheet warranty another plusThe architect also believes strongly in the importance of selecting material and roofing system manufacturers on the basis of reputation and credibility. They want to work with reputable manufacturers who offer recognized finishes. Both Bethlehem and MBCI satisfy this requirement. Shortly after Bethlehem introduced Galvalume sheet to the market in the early 1970s, it offered customers the choice of a warranty on the base metal. It states that the substrate will not rupture, fail structurally, or perforate due to corrosion for a period of 20 years, 6 months. Standard paint warranties are also available. The warranties are contingent on the material being used in accordance with the manufacturer's instructions. Contact Bethlehem for more information on the Galvalume warranty. The Recreation Center is actually the third building at Vistana Resort to use a prepainted Galvalume sheet roofing system. A smaller, earlier built recreation center and the resort's new Reception Center are also topped with MBCI's Craftsman Series SB12 panel system. The Reception Center's roofing panels are finished with a Natural Patina-colored Duranar/Kynar 500 paint system. Like the Recreation Center, the panels were installed over a 5/8-inch plywood deck and 30# felt paper. Both roofing systems were installed by Quality Metals, Inc., Winter Park, FL. |
