Effects of Hail-Caused Dents on the Thermal Performance of Insulation under Single-Ply Roofing
Haag Research & Testing recently published an intriguing study in the International Institute of Building Enclosure Consultants (IIBEC)’s Interface Magazine– Effects of Hail-Caused Dents on the Thermal Performance of Insulation Under Single-Ply Roofing. This article examined whether, and by how much, hail dents would affect the R-value of a roof’s insulation. Could a property owner see a noticeable difference in their energy bills due to changes in insulation?
To conduct our testing, Haag used a heat flow meter (HFM) to evaluate the thermal performance of roof insulation and measured the thermal resistance to conductive heat flow (R-value). We measured the thermal resistance of insulation in several dented configurations, and compared those to samples without dents to determine if the dents resulted in a measurable loss of R-value.
