Cedar Wood
Description
This experiment is on a system consisting of a Cedar Wood cladding panel and a Phenolic (PF) foam insulation panel, separated with a cavity of 50 mm width. It is the third repetition of this system configuration.
Experiment Notes
At approximately 14 minutes ignition of the cedar vertical supports was observed, combined with increased smouldering within the Phenolic foam insulation, leading to a secondary peak in fire size. The Phenolic foam insulation was seen to continue smouldering after the experiment was terminated, requiring extinguishment.
