Drainage Capabilities and Heat Loss of Different Inverted Roof Assemblies
Energy use in buildings throughout North America has attracted significant attention over the past decade. In cold marine climates, rainwater management is also a critical aspect of the building enclosure and energy performance. Various drainage practices used for low slope inverted roofing are often designed without quantified data available regarding the cold rain affects on the thermal performance of the systems.
This presentation will explore the effect of cold water under the roof insulation and its impact on the effective thermal performance in inverted roofs.
