SUMMARY:Predicting Rooftop Surface Temperature Extremes and Impact on Air Barrier Tie-Ins 1.0 CEU/HSW
DESCRIPTION:Predicting Rooftop Surface Temperature Extremes and Impact on Air Barrier Tie-Ins\nRoofing system surfaces can get hot\, sometimes extremely hot due to climatic and indoor design conditions\, direct and reflected solar radiation exposure\, and radiative heat transfer with surrounding objects. Roof surface color\, the position and color of adjacent objects\, as well as the thermal properties of materials are key parameters that greatly influence roofing system peak temperatures. An adjacent parapet wall\, metal coping cover may experience similar surface temperature conditions. Critical rainwater and air control layers transition between roofing and façade systems at the parapet. Designs are complex and rely on tie-ins to allow for differential movement between the parapet wall and roof membrane. Transition membranes many times address scope-of-work issues between roofing and wall air barrier system trade responsibilities. Flashing membranes that maintain the continuity of air and water-resistive barrier systems have upper service temperature limits that vary between 180°F and 300°F. Identifying the parameters controlling climate specific\, rooftop surface temperature extremes will help designers specify the thermal performance requirements for flashing membranes. \nLearning Objectives: \n\nParticipants will be able to list the key factors influencing tie-in temperatures for continuous air barrier systems across roof\, parapet\, and façade assemblies.\nParticipants will understand the impact of solar reflection from adjacent elements on roof\, parapet\, and façade system temperatures\, and identify scenarios that may require high-temperature-rated air barrier system tie-in membranes.\nDescribe the process to simulate and visualize roof\, parapet\, and facade system heat transfer.\nParticipants will understand how temperature rating requirements for tie-in membranes vary across climate zones.\n\n\nRegister Now \nStanley D.
