TopNotch®

Engineered Flooring

The Inside Story

These days, you’re faced with new challenges, like building green, as well as with the age-old unpredictability of Mother Nature. In a profession where only the smart and strong survive, it’s no coincidence that savvy builders like you have made LP® TopNotch® Sub-Flooring one of the world’s strongest-selling products of its kind.

LP TopNotch:
A Smarter
Choice Than Ever.

Top Notch Engineered Flooring

LP TopNotch Sub-Flooring panels are made with three layers of wood strands aligned in alternating directions providing strength, dimensional stability and uniform density. Plus, since LP TopNotch is made from high-yield, fast-growing trees, it’s more environmentally friendly than plywood. In addition to all the characteristics you’ve come to expect from sub-flooring, LP TopNotch offers an even higher level of performance, including:

Moisture Resistant Engineered Flooring

Improved Climate Control

LP TopNotch is better able to weather even rain-prone climates due to its self-draining notch that quickly drains away surface water. Result: high resistance to absorption or edge swell. We’re even able to back up two LP TopNotch options with No-Sand Warranties.

Stronger Moisture Resistance

To help combat moisture absorption problems common to plywood, LP TopNotch Sub-Flooring is manufactured with a water-resistant wax and resin composition. Edge sealant adds another layer of protection.
