When compared to traditional joist construction, manufactured wood floor truss systems are better, stronger, and can be installed faster.
A manufactured floor truss is an engineered structural component assembled from wood members, metal connector plates and other mechanical fasteners. The truss members form a semi-rigid structural framework and are assembled such that the members form triangles. Most builders are familiar with roof truss systems, but may not realize the advantages of a manufactured floor truss system.
The benefits of manufactured wood truss floor systems are many. Floor trusses can span great distances, creating larger open spaces below unobstructed by columns and partitions. Also, the open web design allows for the trusses to expand and contract with humidity and heat. This can help ensure greater long-term stability and reduce the chance of annoying floor squeaks.
The floor truss systems are quicker and easier to install than traditional floor joists, and because they're manufactured in controlled environments, there's less chance of warping, shrinking, and twisting of lumber. Manufactured floor truss systems also save timber resources by reducing the amount of waste wood generated during construction. The consistent size and height of the manufactured floor joist will mean easier subfloor material installation, and the open web design allows for utilities to be run between the floor system without drilling or cutting holes. These benefits will reduce the amount of time trade contractors spend on site, speed up construction, and ultimately save the builder money.
