Quality you can stand behind
At Tolko, we’ve invested time and resources into reengineering our APA-rated Sturd-I-Floor products. Moisture-resistant and edge-sealed, Tolko T-STRAND™ T&G OSB subfloor resists warping and stays true longer. Tolko T-STRAND™ OSB panels are improved, warrantied, and ready to perform.
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.
- 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.
- Fastener guide: Ink-jetted nailing guide on the panel face makes for convenient, easy installation on common joist spacing.
- 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.
- First-class packaging: Packaged in bags and protected with cardboard shrouds.
- Packaged install side up: Installers no longer have to flip panels. The lifts are packaged face up, making it simple to slide the panels off and lay them down.
- Proprietary Edge Seal: Red edge seal protects the panel from swelling.
- Indoor air quality: Contains no added urea-formaldehyde resin (NAUF).
