Exceptional Dimensional StabilityTraditional timber is prone to shrinking, warping, and twisting as it dries. Posi-Joists are manufactured using kiln-dried timber and precision steel webs, ensuring they remain straight and true. This stability virtually eliminates the "creaky floors" that plague older homes and reduces the likelihood of ceiling cracks in the rooms below.
I’ve used Mitek Posi-Joists on a few residential projects now, and overall, they’re a fantastic alternative to traditional solid timber joists or open-web floor trusses. mitek posi joist
Timber is a natural material that can twist, warp, or shrink over time as it dries. Because Posi-Joists are engineered, they offer superior dimensional stability. They remain straight and true, preventing the common issues of squeaky floors or cracking plasterboard ceilings caused by timber movement. This results in a higher quality finish and fewer call-backs for the developer. I’ve used Mitek Posi-Joists on a few residential
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 They remain straight and true, preventing the common
: While the initial material cost may be higher than solid timber, they save significant money by reducing on-site labor (no drilling or notching needed) and speeding up installation by approximately two days per project. 2. Specialized Applications The Posi-Joist Technical Handbook - MiTek
