This report comprises part 3 of a three-part series on an investigation of passive buoyancy-driven roof fire vents in large floor area single-storey buildings.
The report summarises the conclusions from the modelling and experimental parts of the investigation. The primary objective of this report is to present recommendations for the practice of using (plastics) roofing panels that melt or degrade at elevated temperatures for the secondary purpose of venting smoke and heat under fire conditions.
