Abstract:

Tolko proprietary OSB facers are 7/16, 19/32, and 23/32 Performance Category panel sheathing that can be used as facers of structural insulated panels (SIPs) when manufactured to a proprietary mill specification documented in the in-plant manufacturing standard and approved by APA. In addition to the requirements for PS 2, the proprietary OSB facers meet or exceed the higher properties specified in Table 2 of ANSI/APA PRS 610.1 as referenced in the 2021 and 2018 IRC, Table R610.3.2 of the 2015 IRC, and Table R613.3.2 of the 2012 IRC. The properties of the Tolko proprietary OSB facers are quality-controlled on an on-going basis
