What Is Heavy Timber?

“Heavy Timber” is a term used in construction that refers to large pieces of wood used for structural integrity and/or design. The Canadian Wood Council defines heavy timber as pieces that exceed 140mm in their smallest cross-sectional dimension. In other words, massive pieces of sawn lumber.

Uses of Heavy Timber

In construction projects, heavy timber can be used as trusses, especially when a breath-taking visual impact is desired. Because large rooms with high ceilings and heavy timber trusses are pretty spectacular.

Heavy timber can also be used in staircases or balustrades. Instead of using metal and glass which is cold and sterile, wood used in this application gives a room warmth and richness that is unparalleled.

Another possibility is for mantels. Heavy timber can frame large fireplaces to add drama to a room. In addition, since heavy timber is just sawn lumber, it can be finished in any color or texture as required by the design.

Heavy timber is strong and has an extremely long service life. It is also a natural and renewable commodity that does not off-gas anything unpleasant.
