Cross Laminated Timber

A primary benefit of Cross Laminated Timber is it’s the ability to implement CNC technology and 3D models into the design phase.  This can lead to optimization in material handling as well as reduction on waste.  Precision cutting and the ability to recapture waste cut allows additional dimensions of sustainability. Similar to laser cutting, the openings and shape of walls are cut out of laminated panel. The size of the panels allows it to function as walls, floors and roofs, essentially acting as the structure of the building.

Generally speaking the multiple plies of laminated dimension lumber provide strength with greater efficiency than concrete per thickness. This enables longer spans to be achieved in construction dependent on highly renewable materials. Some manufacturers boast of employing up to 40% fibres from FCS (Forestry Stewardship Council) certified lumber.

The ability to work with pre-manufactured panels allows for quick erecting of structures which can be beneficial to regions that observe seasonal construction.  The ability to obtain lumber in most Canadian Regions, coupled with the fact that it is a highly renewable material, makes it a strong candidate for LEED points. However, its limited access due to few manufacturing locations counts against it in the LEED’s category of Regional Materials.
