Mass Plywood Panel

We are excited about the development of our new-to-market, veneer-based, patented, engineered wood product: Mass Plywood Panel (MPP).

Freres has engineered MPP to enhance the natural strength of the wood, while adding dimensional stability. MPP is currently being tested and refined through technical direction from the Tallwood Design Institute, a collaboration between Oregon State University’s College of Forestry and Engineering and University of Oregon’s College of Architecture.

MPP is assembled with Freres SCL panels (called lamellas). They are constructed with density-graded Douglas Fir veneers, which are glued and pressed together, creating large-format wood platforms, beams, and columns that can be manufactured in thickness of 1″ increments to depths up to 24″.

What is a Mass Plywood Panel?

MPP is a massive, large scale, structural composite lumber based panel designed as an alternative to concrete and steel, and to Cross Laminated Timbers (CLT). CLT products have been used in Europe for decades as a substitute for concrete construction, and have recently been used in multi-story construction in the United States.

Freres has engineered MPP to enhance the natural strength of the wood, while adding dimensional stability. It can then be cut precisely to customers’ specifications with advanced Computer Numeric Control (CNC) technologies. Floor, roof and wall panels can be manufactured as large as 11′-10″ x 48′ and up to 12″ thick; beams and columns up to 24″ thick.

All this leads to decreased assembly times and a more economical building solution. MPP is strong and fire-resistant making it an acceptable building material up to 18 stories. It is also lighter, more economical, and more environmentally sustainable than traditional building materials such as concrete and steel.

Why Mass Timber

MPP offers the same benefits as other mass timber products available such as:

  • Fire resiliency
  • Fast construction
  • Small labor force
  • Ease of installation for subcontractors
  • Economical transport
  • Low cost foundations
  • Small seismic forces
  • Environmentally sustainable
  • Aesthetically appealing

Advantages

  • Studies are showing that using veneer as a raw material for a Mass Timber Panel can potentially achieve the same structural attributes of a CLT panel with 20% less wood.
  • Large format panels can be manufactured at the production facility to include window, door, and all other required cut-outs, which will minimize waste and labor on the job site.
  • The relative lightness of the panels can help transportation costs and logistics when constructing buildings on-site.
  • MPP can potentially alleviate current building constraints of labor and land availability by allowing contractors to build quicker and taller with fewer workers.The aesthetic appeal of wood makes MPP a competitive new option.

Dimensions

MPP is a massive plywood panel with dimensions up to 12 feet wide and 48 feet long.

Boasting thicknesses from up to 24 inches thick, the panels may be customized to fit specific projects. Thickness may be constructed in 1 inch increments to provide superior strength and performance.

Can layup and press up to 24”, but are currently limited to cut depth of 12”on CNC and by our certification.

Availability

We are excited to announce that Freres Lumber is one of only three companies in the country who have received certification under the Cross Laminated Timber standard PRG 320. Our Mass Plywood Panel was recently certified by the APA – The Engineered Wood Association. Please contact our Sales Department to see how you can utilize this revolutionary new product.
