Posi Joists

A great alternative to traditional solid joist the Posi joists features a metal web design allowing services to pass through and elevating the need for drilling or notching on site. You can read our installation guide here.

Easy access for the installation and maintenance of the services in a floor zone is the clear advantage of the Posi-Joist flooring system.

With the move towards the building of more sustainable homes, an increasing number of mechanical ventilation and heat recovery (MVHR) systems are being installed in the UK and Ireland, driving more and more architects and specifiers to look for a versatile open web flooring solution.

The system combines the lightness of timber with the strength of the Posi-Strut™ steel web, enabling you to span far greater distances than would be possible with alternative timber products, allowing a variety of internal room layouts within an external shell. This gives you unequaled design freedom across a wide range of applications for both floor and roof in domestic, industrial and commercial applications.
