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.
