Construction Basics - Floor Systems
Structural wood panels and engineered wood framing products can be used in a variety of floor systems. APA Rated Sturd-I-Floor is a combined subfloor-underlayment product designed specifically for single-layer floor construction beneath carpet and pad. When other finish floor products are used, builders often install a separate underlayment grade of plywood over the subfloor.
I-Joists Provide Consistent, High-Quality Floor Framing System
APA Performance Rated I-Joists are the ideal choice for designers and builders who want to provide their customers with high-quality floor systems. They provide consistent performance for the most demanding residential applications. They are simple to install, allow greater design flexibility because they can span long distances, are dimensionally stable, and are lightweight and easy to handle.
Glulam Floor Beams
Glulam beams have superior strength and stiffness and are available in a range of grades and sizes. Framing-grade glulam beams can be used in a wide range of concealed floor framing applications. When the beams are exposed, such as second story floor framing where the glulam is exposed to the floor below, an architectural-grade beam combines the strength of glulam with the warmth and beauty of wood.
