ABOUT POSI-JOISTS
Posi-Joist combines the lightness of timber with the strength of the Posi-Strut steel web to produce a floor and roof system allowing you to span far greater distances than would be possible with alternative timber products.
This gives you unequalled design freedom across a wide range of applications for both floor and roof in domestic, industrial and commercial applications. The Posi-Joist allows a variety of internal room layouts within an external shell due to its clear spanning capabilities.
Easy access for the installation and maintenance of services in the floor zone is the clear advantage of the Posi-Joist system, and with the ever increasing need for MVHR (Mechanical Ventilation and Heat Recovery) systems, Posi-Joist provides a perfect and simple solution that just isn’t possible with alternative solid timber products.

LWK Developments Ltd are a MiTek Posi-Joist designer and benefit from the very latest industry leading design software. With this specialist software we are able to create your project specific design. Detailed output drawings are provided for approval and manufacture, but it is the 3D viewer tools that really separates Posi-Joist from the rest.
Designs are shared via a free cloud based 3D viewing platform, allowing for a fully interactive 3D model of the floor or roof to be viewed on any internet enabled device. No apps are required, you will be sent a link to your model and simply click it to view in your browser.
