OSB, PIR, rep 3
Oriented Strand Board (OSB)
Description
This experiment is on a system consisting of an Oriented Strand Board (OSB) cladding panel and a Polyisocyanurate (PIR) foam insulation panel, separated with a cavity of 50 mm width. It is the third repetition of this system configuration.
Experiment Notes
At approximately 6 minutes the OSB panel began to touch the insulation panel, affecting the mass measurements. At approximately 7 minutes the OSB panel began to collapse, causing a sudden change in the mass measurements as debris fell into the debris tray, onto both load cells, or off the entire assembly.
