Proper Panel Spacing
It is important to properly space OSB and Plywood panels to allow for natural expansion as they adjust to the moisture in the environment. APA the Engineered Wood Association recommends 1/8-inch space between panels for a smooth and secure surface without buckling. For more information, view the following resources from APA:

Features and Benefits
Pro performance: 45% less swell and double the internal bond of standard grade OSB T&G Subfloor.
Tested: APA-certified PS2 for guaranteed consistent standards.
No slip surface: Manufactured with a continuous press, this subfloor does not need to be sanded to meet thickness tolerances. By not sanding, we are able to offer an imprint screen, no-slip face.
Superior moisture durability: This enhanced subfloor is unsanded, which preserves the integrity of the strands and maintains a protective wax surface for greater water repellency.
Proprietary Edge Seal: Red edge seal protects the panel from swelling.
Fastener guide: Ink-jetted nailing guide on the panel face makes for convenient, easy installation on common joist spacing.
First-class packaging: Packaged in bags and protected with cardboard shrouds.
