Sheathing the Floor System
Wet weather calls for tough, water-resistant subfloor materials.
Framing houses in the middle of a Kentucky winter means cold temperatures and lots of rain—conditions that shape our subflooring choice. We picked AdvanTech subfloor for two reasons. As I mentioned in my previous post, we want a stiff, squeak-free floor. We’ve found AdvanTech to be stiffer than some other subflooring options. To make sure it’s a silent floor we need to prevent movement and gaps between the subflooring and the joists. The TJIs are one part of addressing this. The other is gluing and screwing the subfloor. The AdvanTech subfloor adhesive creates a strong bond between the TJIs and the subfloor that prevents squeaky floors. One thing we like about the adhesive is that it can be applied down to 20⁰ F and when the wood is wet or frozen. The framers spray the polyurethane foam-type glue along a 4 ft. row of sheathing, tack them in place and another crew member follows behind screwing down the panels. Our framers use Simpson StrongTie collated screws and screw gun once the subfloor is down. It’s easier on the body than bending over to drive screws, and it is a faster way to follow the best practice of gluing and screwing the subfloor.
The other thing we like about the AdvanTech panels is we don’t have to worry about the wet weather swelling the edges; edge swelling hasn’t happened to us with this product so we don’t have to sand before installing the finish floor.

Concrete floors prove to be an incredibly versatile and practical option for a wide range of spaces. Their remarkable durability and low maintenance make them particularly well-suited for high-traffic areas such as warehouses, garages, and retail stores. What's more, concrete floors offer a sleek and minimalist aesthetic, with the added advantage of being customizable through a variety of finishes, stains, and colors to perfectly align with any design preference. Thanks to their exceptional thermal mass, these floors contribute to regulating indoor temperatures and reducing energy costs. Their resistance to stains, water, and fire ensures reliability and longevity, while their sustainable nature and ease of cleaning foster a healthier indoor environment. Ultimately, concrete floors effortlessly blend functionality, style, and sustainability, establishing them as an outstanding choice for any space.
