LP® TopNotch® Sub-Flooring
LP TopNotch Sub-Flooring is the only self-draining sub-flooring. Our patented RainChannel™ system allows water to drain through notches along the tongue and groove and the panel ends. LP TopNotch products also feature a moisture-resistant edge sealant to further reduce moisture absorption and edge swell. Because strength requirements and weather conditions vary from job to job, we offer LP TopNotch Sub-Flooring in three different performance solutions. That lets you choose the right product for every job. Click here to see the three different choices. To learn more about this product click here.
