RAISE THE ROOF! R-value is a measure of thermal resistance used in the building and construction industry. The higher the number, the greater the insulation. Compression strength relates to how much pressure the material can take. requirements — into account. However, "There are two primary concerns when it comes to roofing insulation," says Tony Matter, marketing communications manager, Carlisle SynTec Systems, "R-value and compression strength." R-value is a measure of thermal resistance used in the building and construction industry. The higher the number, the greater the insulation. Compression strength relates to how much pressure the material can take. "There's a lot happening up on a college roof," says Matter. "Mechanicals are found up there and workers have to clean and service them, which means they are walking up on the roof and potentially harming it." "Polyiso is the industry standard," Matter continues. "It has a high R-value and it's easy to install. In fact, gypsum board has a 0.5 R-value, while the same thickness polyiso has a 2.5 R-value. Expanded or extruded polystyrene foam (EFP) is a less expensive option, but it has a lower R-value, so you have to use more of it to get the desired effect." That desired effect changes every few years. "There is nothing new in insulating STARTING FROM THE TOP DOWN. Building owners (as well as building designers and building codes) want high-performance insulation under their roof membranes to curb the growing costs of heating and cooling. When specifying roof insulation, consider the unique thermal needs of the building. The proper insulation choice will satisfy applicable energy codes and also result in a roof assembly that is approved by the property insurance carrier. 30 COLLEGE PLANNING & MANAGEMENT / DECEMBER 2012 WWW.PLANNING 4EDUCATION.COM
