Design a Home with LP® TopNotch® 350 Durable Sub-Flooring

Neil Freidberg, Building Science Manager at LP, has been a leader in building science for more than a decade. His expertise in the field provides a closer look at the importance of products engineered to work together. 

We asked Neil to share how he would design a made-to-last house with LP® TopNotch® 350 Durable Sub-Flooring. Here’s what he had to say: 

Q: Every climate has unique needs that are important to take into account when selecting building materials for any given project. What climates lend themselves to LP TopNotch 350 sub-flooring?

A: The great thing about LP TopNotch 350 sub-flooring is that it works in every climate. It can be used as a dependable sub-flooring solution no matter the area in which you’re building.

Q: Rain during construction is often unavoidable. What is the importance of home design with sub-flooring designed to drain water? 

A: Standing water is one of the worst things for your build because it affects not just the build during construction but also the amount of moisture you have to remove once your house is done. So, if water isn’t properly drained away during construction, moisture will still be retained in your sub-floor, and it will have to be addressed before the finish flooring is installed in most cases. 

If flooring is significantly affected by moisture or even leads to a callback, it’s the last thing you want to rip up once your build is completed and the homeowner has moved in. With LP TopNotch 350 sub-flooring, you’ll have a unique RainChannel® notch system that allows water to drain away during construction. 

Q: How would you approach LP TopNotch 350 home design with other LP Structural Solutions products?

A: LP TopNotch 350 sub-flooring is always great to mix and match with LP Legacy® Premium Sub-Flooring, especially for multi-level structures. On the top floor I recommend using LP Legacy panels, which can be exposed to more rain during construction. Then use LP TopNotch 350 panels on the lower levels to help any waterfall from upper levels drain away through the RainChannel® notch system. 

Beyond sub-flooring, LP WeatherLogic® Air & Water Barrier proves to be a great defense against moisture by contributing to a tighter building envelope.

Why Build With Carbon Negative Building Materials?

In our pursuit of sustainable and environmentally friendly products, we completed five LCAs and EPDs for our LP® Structural Solutions portfolio. Along with LP® SmartSide® Trim & Siding, these EPDs demonstrate the carbon negativity of our products. That means that our products store more carbon than is released during their entire life cycle, making us a meaningful part of the climate solution.

Tighter Lot Sizes Focus More Attention on Fire Separation Distance

It’s no secret that many developers, architects and builders are reducing lot size as one way to hold down housing costs and maintain profitability. In fact, the rise of zero-lot-line homes, odd-lot/infill development and compressed parcel spacing is helping shape a new housing normal for many communities. This downsizing is focusing attention on minimum fire separation distance.
