Assessment of Thermal Bridges due to Roof Fasteners

The RCI Foundation has approved funding for a study, titled “Laboratory Testing of Roof Assemblies for Comparison with Simulated Models: Thermal Performance Assessment of Thermal Bridges due to Roof Fasteners”.

Proposed experimental setup of roof assemblies in the test chamber

The team, consisting of Dr. Elizabeth Grant and Dr. Georg Reichard, along with our students, as well as industry sponsors Simpson Gumpertz & Heger (SGH) and GAF, will conduct selected laboratory tests to compare the thermal performance of physical models of simple roof assemblies under different controlled laboratory environmental conditions with computational models of these assemblies.

The overall goal of the project is to provide a better understanding to the industry of simulated versus tested thermal conductance in 3-D configurations, in support of relative comparison of quantitative thermal effects of fasteners in different roof assemblies.
