In addition to traditional solid softwood joists we are able to offer you two high performance engineered-floor options designed in-house by our highly skilled technical teams.

(Available from all Walker Timber Group Companies)
The Finnframe Floor System does the job of specifying for you. It converts your own floor plans into a 3-D image of the supporting structure together with a complete bill of materials and detailed site plans. Those plans go with
Finnjoists and other engineered wood products to provide a comprehensive drawing-board to building-site flooring system. The Finnframe Floor System is an inspired mix of quality, technology, and service - a total flooring system devised specifically for the UK construction industry. Most important of all, it's the only flooring system that currently complies with Eurocode 5.
The I-joist (FJI) with its Kerto flange and high quality OSB panels, has a high strength to weight ratio and therefore produces lighter, longer spans combined with quick and easy installation, so reducing your build time and increasing efficiency.
The FJI is at the heart of the finnframe flooring system.
FJIs are available in the following standard dimensions:-

Posi-Joist - The Alternative Joist System
(Available from Guildway, Cox Long & Pattrick and Thompsons)
You simply can't afford to ignore the advantages of the Posi-Joist system.
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.
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.
Exceptional floor performance from a minimum 72mm wide fixing surface makes flooring easy, controls shrinkage, and with precision engineering it all reduces those tiresome return visits and remedial work.
More .... benefits such as the unique open web design provide an area in which Plumbers and Electricians will find it easy and convenient to work. The job's done far more quickly and the contractor makes 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.
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
