The room-in-roof truss, or attic truss, is a simple means of providing the structural roof, floor and internal walls in the same component. Attic roof trusses are designed to form the top storey of a dwelling with habitable room spaces; such as additional bedrooms, a self-contained annex or an office space, by leaving it free of internal web members.

A fink roof truss is traditionally the most commonly used truss type, providing a simple, adaptable and cost efficient roofing solution. The “fink” is a basic webbed truss design that provides the most economical roof solution.

Spandrels are specially designed and manufactured from timber framed panels clad with plasterboards that enable you to separate roof areas between adjoining houses. This will achieve a guaranteed 1hr fire protection barrier.

Raised ties are designed to provide a higher ceiling line and more internal room height than the fink, making them the truss choice when requiring vaulted/sloping ceiling effects either for aesthetic purposes or to conform to overall height planning restrictions

Posi-Joist combines the lightness of timber with the strength of the Posi-Strut steel web allowing you to span far greater distances than would be possible with alternative timber products. Furthermore the exceptional strength characteristics result in much firmer floors with far less ‘bounce’ when compared to I-beams or alternative floor systems.

Posi-joists provide the perfect solution to orangery roof requirements. The excellent characteristic strength properties of posi-joists, in comparison to solid timber or alternative engineered timber beams, combined with the lightweight nature of the posi-joist system...

Posi-Rafters are parallel chord trusses, plated together with Posi-Strut metal webs. As with Posi-Joist floor joists they are designed and manufactured offsite and tailored to the requirements of each individual project. They arrive made to measure and accompanied by full layout drawings for speed of erection.
