How to Protect Your Sub-Floor From Moisture: How RainChannel® Technology Works
As a builder, moisture is always a top concern once the sub-flooring goes down. The time when the structure is fully enclosed varies wildly during the build cycle and damage can cause a significant delay.
One solution to help protect the sub-floor from rainwater damage during construction is to use LP® TopNotch® 350 Durable Sub-Flooring.
What is LP TopNotch 350 Durable Sub-Flooring?
LP TopNotch 350 Durable Sub-Flooring is an OSB sub-flooring designed to reduce the impact of moisture during construction. This, along with its stability and great price point, makes it a popular choice among builders.
Offering added protection from moisture damage, LP TopNotch 350 panels feature the unique RainChannel® technology that helps drain water away during construction.
How Does the RainChannel® System Work?
Just as treads on a tire push water through its grooves to disperse rainwater, the RainChannel system uses a self-draining notch design to quickly channel water away. This helps prevent water from standing too long and creating any potential moisture issues.

The system also offers a moisture-resistant edge seal that can reduce the need for sanding.
Thanks to the RainChannel system, LP TopNotch 350 Durable Sub-Flooring offers a superior limited warranty. LP backs LP TopNotch 350 panels with a 200-day “no-sand” warranty and a 50-year transferable limited warranty.
For a “no-squeak” floor your customers will certainly appreciate, discover how LP Legacy® Sub-Flooring Adhesive can give you a sturdy and quiet sub-floor.
