Mitek — Joists

Moreover, because the joists are cut to length at a truss plant (not on site), job site waste drops from 15% (for dimensional lumber) to under 3%.

Because the system is "open web," there are large triangular voids between the chords, as opposed to the solid center found in I-joists or dimensional lumber.

Mitek open-web joists combine timber flanges with V-shaped galvanized steel webs (Posi-Struts) to create engineered floor systems that allow for easy, non-destructive routing of plumbing, electrical, and HVAC services. Their open design provides superior spanning capability, a wider nailing surface for reduced squeaking, and faster,, more sustainable installation compared to traditional solid-sawn lumber or I-joists.

Engineered to maximize living or storage space in roof areas, often used in conjunction with MVHR systems. Cost-Effectiveness and Sustainability

Unlike solid timber joists or even many I-joists, the open-web design allows for easy installation of services, making them highly desirable for modern building techniques. Key Advantages of MiTek Joist Systems 1. Easy Service Installation (Open Web Design) Moreover, because the joists are cut to length

No product is perfect. Mitek joists must be protected from weather—exposed to rain for weeks, the OSB web can swell and delaminate. They also cannot be field-notched for pipes; you must use the factory holes or order custom knockouts. And fire resistance is lower than solid heavy timber, requiring careful specification of drywall thickness in fire-rated assemblies.

While the initial unit cost of a Posi-Joist might be higher than a standard solid timber joist, the total project cost is often significantly lower. Their open design provides superior spanning capability, a

against other materials (I-joists, solid wood)? Installation details ? Let me know your specific focus! Posi-Joists – MiTek UK and Ireland

MiTek joists are engineered for performance. Due to the depth of the truss and the strength of the steel webs, they can span significantly further than equivalent sizes of solid timber. This allows for larger, open-plan rooms without the need for intermediate load-bearing walls or beams.

The term "MiTek Joist" generally refers to metal-web system floor joists. These are a form of , designed to offer a superior alternative to solid sawn timber (like 2x8 or 2x10) and I-joists.

And that is the mark of great engineering: invisibility. Mitek joists don’t announce themselves. They don’t creak, sag, or twist. They simply perform, quietly carrying the weight of modern architecture—open floor plans, tile bathrooms, home theaters—on a skeleton of wood and glue that is stronger, lighter, and smarter than the forest ever was on its own.
