A detailed investigation has been conducted into methods for determining the thermal performance of horizontal ceilings under pitched roofs. Existing literature on relevant calculation, simulation and test methods was reviewed, and an extensive computational fluid dynamics (CFD) simulation study was conducted. Results from the CFD simulations were used to assess the accuracy of standard thermal bridge calculation methods when applied to timber-framed and steel-framed ceilings under a roof space.
