SR198 Effective passive roof venting using roof panels in the event of a fire: Part 2 - experimental results (2018)

This report comprises part 2 of a three-part series on aspects investigating passive buoyancy-driven roof fire vents in large floor area single-storey buildings.

The primary objective of this report is to describe the preliminary small-scale test apparatus developed to assess fire venting potential of roof sheeting. Recommendations based on the analysis of this investigation are presented.

The scope of this report is limited to the development of a potential test method for assessing the potential fire venting characteristics of roof sheeting. Assessment of specific materials and proprietary systems was outside the scope of this project, since roof construction method, specific engineering additives to the base material and geometry (e.g. thickness) contribute to the fire venting performance of the sheeting.
