Division 7 Ebook Page 336 FOAMULARŪ in Metal Roofing Case Study

began on an 850-seat auditorium addition to the high school. At the onset of construction, a sample of the FOAMULAR insulation used in the original buildings (now 10 years old) was removed and submitted for testing. According to Site Superintendent Paul Childers of Nielsen Builders in Charlottesville, the sample "looked brand new!" The insulation sample was tested at the Owens Corning Science & Technology Center in Tallmadge, Ohio and found to have 95 percent of its original R-value (R-5 per inch). When compared against other ASTM C 578 Type IV specifications, the sample met or exceeded all of the property requirements. For example, when tested for Compressive Resistance, the FOAMULAR insulation exceeded the ASTM minimum by more than 50 percent. Good Results in Bad Weather These results were especially good news for the school, which is in an area of the country that experiences an average annual snowfall of 14 inches. According to the Virginia Department of Emergency Management, over the past 10 years there have been "back- to-back Nor'easters," major ice storms, freezing temperatures, and one winter in which Charlottesville recorded nearly nine inches of sleet in a single storm. "These results show that FOAMULAR insulation does, indeed, deliver stable and consistent R-values over time," says Saverio Marzella, Owens Corning Field Sales Manager for foam roofing. Marzella says there is a trend in the construction industry toward sustainable and re-usable properties in roofing materials, including insulation. "With these performance results, architects can specify FOAMULAR insulation with confidence, knowing it will provide stable and consistent value over time. "Rigid insulation's compressive strength is especially important when constructing an architectural standing seam roofing system, the system specified for the high school," adds Marzella. "In architectural standing seam roofs, the use of rigid insulation is common and one of the critically important properties of rigid insulation is its compressive strength, which in the in-service sample has far exceeded the specification well into the life of the roof." Jack Clark, an Architect from Rancorn Wildman Architects PLC - the firm selected for the project - added that "keeping moisture out is important in any roofing system." This is because moisture penetration can cause a permanent loss of R-value, and after repeated penetrations the insulation can become practically useless. Extruded polystyrene insulation (XPS) will not rot or decay, support fungus or mold growth, or provide sustenance for insects or vermin. The energy cost savings is also a consideration when selecting FOAMULAR insulation. Extruded polystyrene insulation has a unique closed-cell structure that enables the foam to retain its exceptional long-term thermal performance year after year. PINK and Green Insulation products have a profound impact on the environment. A typical pound of insulation saves 12 times as much energy in its first year in place as the energy used to produce it. This means the energy consumed during manufacturing is saved during the first 4 to 5 weeks of the product's use. The insulation continues to save this amount of energy every month throughout the life of the building in which it is installed. The performance attributes of extruded polystyrene - stable R-value, moisture resistance and high compressive strength- make it an excellent material choice for insulation. In a variety of harsh and unique applications, XPS is often the only product accepted by building code agencies. Due to the thermoplastic nature of FOAMULAR insulation, virtually 100 percent of all in-plant scrap is recycled and reused in the primary extrusion process. In addition, the product is an excellent candidate for using post-consumer and post-industrial recycled and/or recovered polystyrene foam. FOAMULAR insulation is certified to have at least 15 percent recycled content but often contains up to 30 percent. CASE STUDY Monticello High School, Charlottesville, Virginia.
