Low Embodied Carbon! Besides aesthetically pleasing and fitting well with our Pacific Northwest roots, mass timber construction offers viable eco-conscious solutions to the traditional multi-story, concrete, or steel apartment blocks. The production of steel or concrete emits large quantities of carbon dioxide (CO2) accounting for 40 to 50 percent of greenhouse gas emissions. Renewable materials, such as Cross-laminated timber (CLT), can help mitigate the rate of global warming.

A CLT panel consists of several layers of dried lumber boards stacked in alternating directions, bonded with structural adhesives, and pressed to form a solid rectangular panel.  These panels are lightweight yet very strong with superior acoustic, fire, seismic, and thermal performance.  Cross-laminated timber is fast and easy to install, offers design flexibility, and low environmental impacts.

The 4 key things to remember about Mass Timber are:

  1. Mass Timber is Fire Resistant
    • In the instance of a fire exposed mass timber chars on the outside, which creates an insulating layer protecting interior wood from damage.
  2. Mass Timber is Strong
    • Mass Timber projects weigh roughly 1/5th that of similar steel or concrete buildings. This causes reduction to the foundation size, inertial seismic forces, and embodied energy improving its performance during seismic activity.
  3. Mass Timber is Sustainable
    • Replacing steel with mass timber would reduce carbon dioxide emissions by between 15-20%.
  4. Mass Timber makes construction cost-efficient
    • These projects are around 25% faster to construct than concrete buildings and require 90% less construction traffic.
    • The construction sites are also safer since mass timber panels are prefabricated, and then assembled on site.
