First-Timer’s Reward
If you’re a professional builder working with LP® TopNotch® products for the first time, you’ll be instantly impressed by its moisture resistance. By its strength and dimensional stability. By how easily it installs. 
And no matter how extreme the weather, you won’t believe how effectively our notching system drains away surface water to reduce moisture absorption, swelling and the need to sand. But on-site hassle isn’t all you’ll save.
