A number of test series have been conducted at FPInnovations to evaluate the lateral resistance, fire resistance, and acoustic performance of the new Midply shear wall configuration. The results showed that the seismic force modification factors prescribed in the NBCC can be used, along with the enhanced lateral strength and stiffness. Moreover, with some minor design
considerations, it was found that the new Midply with the resilient channels and insulation materials in both sides of the wall and both cavities can provide at least 1 hour of fire-resistance rating and provide at least an ASTC of 47.
