On a construction site, time is money. Mitek Posi-Joists arrive pre-fabricated to exact specifications, meaning there is almost zero waste on-site. Because they are manufactured in a controlled environment, they are consistently high-quality and ready to be craned or lifted into position immediately. The "built-in" service void means follow-on trades can complete their work faster, shortening the overall build schedule. Sustainability and Future-Proofing
Improved Acoustic and Thermal PerformanceThe wide flanges of a Posi-Joist provide a large surface area for fixing floorboards and ceiling plasterboards. This not only makes installation faster but also contributes to better sound insulation. Additionally, the void created by the open webs allows for a continuous layer of insulation or the easy integration of Mechanical Ventilation with Heat Recovery (MVHR) systems.

A Posi-Joist is an "Open Web" or "Metal Web" joist. It combines the structural solidity of timber with the versatility of steel. The design is ingeniously simple yet highly effective: it consists of softwood flanges (top and bottom chords) connected by a unique, precision-engineered steel web system.

Absolutely – especially on projects with underfloor heating or complex M&E runs. The "built-in" service void means follow-on trades can
: The open-web design creates a large internal zone for running pipes, electrical wiring, and HVAC ducting. This is especially critical for modern Mechanical Ventilation and Heat Recovery (MVHR) systems that are difficult to fit through solid timber.
