Notes:

Footnote 1

Control specimen: single layers of 12.7-mm gypsum board were fastened using 32-mm galvanized ringed wallboard nails every 200 mm o.c. at the edges and in-field. The framing consisted of 38 mm × 89 mm fir wood studs at 406 mm o.c. spacing. The wall specimen was 2.4 m × 2.4 m.

Footnote 2

"PSL Vinylroc" specimen: the framing was notched to accommodate two 25 mm × 100 mm Spruce-Pine-Fir (S-P-F) furring evenly spaced across the studs at 800 mm o.c. The furring were fastened using 56-mm nails. Structural adhesive was applied to the furring strips in a 9.5-mm bead and serpentine pattern. The "PSL Vinylroc" sheathing was fastened to the framing using 6.35 mm × 31.75 mm staples on the perimeter at 152.4 mm o.c. spacing. The wall specimen was 2.4 m × 2.4 m.

Footnote 3

"PSL Vinylroc" does not exceed the control specimen; therefore, it meets the requirements. See Section 3, Conditions and Limitations, in this Report for the installation requirements as per Subsection 9.23.13., Bracing to Resist Lateral Loads Due to Wind and Earthquake, of Division B of the NBC 2015.

Footnote 4

The control specimen and the "PSL Vinylroc" specimen failed prior to reaching the applied racking load. As a result, no deflection or residual deflection was recorded.
