Abstract
recent research into the real-world performance of insulation materials in roofs and walls has shown that the industry’s reliance on r-value at a standard temperature does not always tell the whole story. This paper will present measurements from several fieldmonitoring studies across north America that demonstrate how insulated roofs and walls exhibit thermal performance that is different than assumed by designers. Specifically, results show that insulation properties vary with temperature (i.e., performance changes at high or low temperatures). This is important because of peak energy demand, annual heating and cooling costs, occupant comfort, and durability considerations.
