The Role of Thermal Mass in Low-Slope Roof Design

September 19, 2022

Thermal mass affects the dynamic flow of heat into or out of buildings. While important, it has not received as much attention as thermal resistance. Building codes continue to increase thermal insulation requirements as the primary method to improve the thermal efficiency of building enclosures. For example, the International Energy Conservation Code (IECC) only specifies […]
