We at DWB Timber Engineering are confident that the Open Web flooring system will soon become the one product used throughout the industry for joisting all developments. You simply can’t afford to ignore the advantages of the Open Web Posi-Joist™ system designed and fabricated by DWB.

To start with, because Posi-Joist™ combines the lightness of timber with the strength of the Posi-Strut™ steel web, you can span far greater distances than would be possible with alternative timber products.

DWB’s Posi-Joist system gives the building designer unequalled freedom when scheming a new project right across a wide range of applications in domestic, industrial and commercial situations. The Posi-Joist™ allows a variety of internal room layouts within an external shell due to its clear spanning capabilities.

Exceptional floor performance from a minimum 72mm wide fixing surface makes flooring easy, controls shrinkage, and with precision engineering reduces tiresome return visits and remedial work.

More benefits become apparent post instalment due to the unique open web design Plumbers and Electricians will find it easy and convenient to work with no notching or drilling needed along with the strengthening required with other systems to do this. The job’s done far more quickly and the contractor can make worthwhile savings.

Even on long spans, no herring-bone strutting is necessary with the Posi-Joist system. If the span exceeds 4m, a strong-back is installed at mid-span with spans below this taking their bracing from the 22mm decking and plasterboard.

The Posi-Joist™ does not just joist floors it can adequately span for flat and pitched roofs. Its span capability and timber flanges make it the more desirable alternative to all steel systems.

Posi-Joist™ standard details are published along with the DWB/Mitek World of Floor Technology, available in the document library area of this site.

Posi-Joist the only open web joist system suitable for use with the Screedflo (concrete) Acoustic Flooring System. This results in a floor which performs like a solid concrete floor in a lightweight structure. Please see our document library for further details on Screedflo systems.

Open web joists can also be incorporated to further increase the benefits of attic trusses. Please see our Attic Truss section for additional details.
