Freres doesn’t stop at crafting industry-leading engineered wood products — our use and sale of wood residuals ensures that no timber goes to waste.

Building Products

FRS icon veneer


Freres’ veneer products are made with a lathe that peels thin layers from logs as large as 48 inches or as small as 6 inches in diameter. This process reduces waste since more of the wood goes into the final product than cutting square lumber from round trees.

FRS icon plywood


Freres produces a wide range of PS1-23 certified commodity plywood panels from ⅜” to 1 ½” thick, in lengths up to 10 feet. Plywood grades also include Putty Touch Sand (PTS), underlayment, and all other sheathing products. Through our unique layup systems we can also produce Structural Composite Lumber products with ASTM D 5456 certified LVL grades. Custom veneer-based panels are available at customer request.

Mass Ply

Freres’ Mass Ply Panels and Mass Ply Lams are patented, veneer-based, engineered wood products that serve as sustainable substitutes for traditional building materials like concrete and steel. Among many environmental benefits, Mass Ply products require less energy to produce, generate fewer greenhouse gas emissions, and offer a greater thermal performance.

FRS icon lumber


Freres produces lumber products out of the processed cores from veneer peeling and scrag logs from timber sales. Our lumber products are typically industrial grades, not dimensional lumber for residential construction.

Maximize leed points for your next building.

Mass Ply has the potential to maximize the points for your next LEED certified building. Mass Ply inherently aligns with the U.S Green Building Council’s (USBG) principles with its reduced energy capabilities and its environmental benefits. Freres is currently taking steps to ensure your LEED project gets the maximum points from the use of Mass Ply (See Life-Cycle Assessment).

Residual Products

FRS icon ag

Bark Dust, Chips, and Sawdust

Freres produces and sells residuals like bark dust, chips, and sawdust, which are used in a variety of markets such as residential construction, farms, and nurseries.

FRS icon biomass energy

Biomass Energy

Residual wood from manufacturing operations is burned to produce biomass energy, a renewable energy used as heat in manufacturing processes or to generate electricity. Steam-generated electricity from Freres’ cogeneration plant supplies the local utility with enough energy to power more than 5,000 households while also delivering heat for plant production processes.

FRS icon biochar


The production of biomass energy also creates a byproduct called biochar. This substance enhances soil and retains carbon, which helps climate-conscious companies decrease their carbon footprint. Freres is certified as a Carbon Removal Supplier through the marketplace for this product.

Please see our Life Cycle Assessment for a detailed examination of the CO2 sequestration of our biochar product.
