Structural timber posts and beams can be used to achieve long spans and elegant curves in a structure, and timber columns are often left exposed to view.

Made from hardwood, softwood, glued laminated timber (glulam) or laminated veneered lumber (LVL), the engineered beams can be constructed as solid beams or I-joists.

I-joists, or I-beams, are lighter in weight than solid beams, and can achieve longer spans. The webbing may be open or closed, and is made from metal or an engineered timber material such as oriented strand board (OSB).

Choosing FSC or PEFC certified products will go some way towards ensuring the project’s sustainability.

Roof trusses and structural timber flooring systems complete the timber-frame.
