The Freedom of Choice
Having a choice is good. Having three is even better, especially when it comes to sub-flooring. Since certain jobs often have specific strength requirements and since regions have their own own weather patterns, you need the range of options offered by the LP® TopNotch® family.
We offer options able to meet any strength requirement or climate challenge. And for those of you working in various parts of the country under vastly different weather conditions, you can now customize your order to meet every extreme and benefit from single-source speed and economy.
Performance You Count On
No matter which LP TopNotch series you choose, you’ll benefit from our patented self-draining notch system that reduces standing water. Of course, our engineered panel composition assures built-in moisture resistance, enhanced even more by our edge sealant. You’ll discover that LP TopNotch installs quickly and easily, thanks to its self-spacing tongue-and-groove edge construction. It’s also backed by some of the strongest sub-flooring warranties in the business.
