In this project, the main objective was to evaluate the “best bet” experimental mat structure design previously identified by FPInnovations in 2018/19. This mat structure was comprised of three strand size classes incorporated into six equal weight mat layers. Both experimental and control panels were prepared at 39lb/ft³ and 35lb/ft³ densities and tested for dry static bending, single cycle bending (D4), concentrated static load, thickness swell, and internal bond strength.
A methodology was developed to evaluate the performance of different commercially available siding materials when exposed to high and low radiant heat loads. The materials evaluated in this study were engineered wood, fibre cement board, cedar siding, and vinyl siding. The time to ignition of the wall prototypes was used to evaluate the performance of these materials.
