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:
