Source materials
We source our lumber from forests that are vetted for their sustainability practices, tight grain structure, integrity, and quality.
Spruce-Pine-Fir (SPF)
SPF is a versatile softwood lumber with high strength-to-weight ratio, stability, and ease of workability. We source SPF primarily from certified forests in western Canada and from the Rocky Mountains, Pacific Northwest, and Great Lakes regions in the United States.
Douglas-Fir-Larch (DF-L)
DF-L is valued for its strength and natural resistance to decay and moisture. It is preferred in applications where higher weight and density are needed. We source DF-L primarily from the Pacific Northwest, the Rocky Mountains, and the interior of British Columbia.
Southern-Yellow-Pine (SYP)
SYP is grown primarily in the southern United States and is known for its high strength and stiffness, natural resistance to decay and insects, and warm natural appearance.

How is mass timber made?
At MMT, we form our products by gluing and pressing wood into massive building components. Mass timber can also be made using nails (nail-laminated timber) or dowels (dowel-laminated timber) to join lamstock.
Design capabilities with mass timber
From exposed wood columns to sweeping, curvilinear roofs, the expressive potential of mass timber is boundless.
