Engineered Outperforms Open Web
When it comes to floor joists, professionals know that engineered and precision-manufactured solutions like BCI® and AJS® joists outperform solid sawn open web floor trusses (OWFT) by almost any measure.
Let’s look at the common myths vs. reality
Myth
Engineered I-joists make running HVAC, plumbing & wiring harder
Reality
BCI and AJS joists can easily have holes cut in the web (up to 22” rounded rectangular) or punch-outs removed, making running HVAC, plumbing & wiring quick and simple for the trades in most applications.
BCI Joists Have Room to Run
Myth
The manufacturing process for engineered I-joists and OWFT are similar
Reality
Engineered I-joists like BCI and AJS joists are designed and built to exact manufacturing standards — and are also subject to rigorous testing to ensure high-quality standards are always met. Each joist is tested before shipping. The result is that BCI Joists are consistently strong, durable, and flat floors. You won’t get this from open web floor trusses.
Predictable Performance Adds Value
Myth
Engineered I-joists and OWFT perform at about the same level
Reality
Due to the strict manufacturing process and strict engineered values, BCI and AJS joists provide measurable performance. This information is used in the BC FloorValue software to analyze and design floors to help ensure they meet customer expectations. This results in stable, sturdy, and quiet floors — no more bounce or rattling dishes in the cabinet as you walk by.
Quality Construction = Happy Customers
Myth
Engineered I-Joists and OWFT install similarly
Reality
BCI Joists are engineered and manufactured so they’re lighter, easier to handle and field-trimmable without sacrificing strength. Their factory-controlled consistency ensures uniform installation. In contrast, open web trusses are heavy, can vary by build with larger crews, and more time is needed to ensure point loads and bearings are in-line floor to ceiling.
The True Price Includes More Than Materials
Myth
All manufacturers stand behind their products
Reality
Do open web trusses come with a warranty? Good question. Typically not. BCI and AJS joists, on the other hand, always include a straightforward, industry-leading limited lifetime warranty backed by a company with more than 60 years of experience
