2 My Forest Products Story As a youth growing up in the Nicolet National Forest (Wisconsin), I understood the connection between the forest and Connor Forest Products where my Dad worked. Despite moving from Laona in 5 th grade, I accomplished my youth goal of being a forester with a career in forest products. After 25 years as a wood specialist in Minnesota, I joined the Forest Service s FPL in 2015 to fulfill a career goal and work to strengthen the connection between our forests, research, and markets. I am proud to work alongside my Forest Service colleagues and partners to support resilient forests and communities.

3 USDA Forest Service Forest Products Laboratory Established Permanent Employees (50 Scientists) FY16 Federal Funding $26.6 million 150 Cooperative R&D agreements Program Leverage $4 - $5 million

4 A key element in maintaining healthy, resilient forests is our ability to provide value-added products from the full complement of forest biomass.

8 American National Standard Defines CLT Component requirements Performance criteria Qualification Quality assurance Terminology

9 CLT Production Considerations Lumber Considerations Species Grade Dimension Moisture content Adhesives Manufacturing

10 CLT Lumber (Per PRG ) Machine Stress Rated or Visually Graded Dimensional Lumber Douglas-fir, southern yellow pine, SPF, SPF south Parallel layers: #2 or better (visual grading) or MSR 1200f or better (machine grading) Perpendicular layers: #3 or better Specific gravity > 0.35

11 CLT (Per PRG ) Thickness not less than 5/8 or greater than 2 2 by 4, 6, 8, 10 common in North America Dried to 12% moisture content before layup Glulam adhesive standard (AITC 405) Phenol-resorcinol formaldehyde (PRF), Emulsion polymer isocyanate (EPI), One-component polyurethane (PUR)

14 Nail Laminated Timber NLT is created from dimensional lumber stacked on edge - 2x4, 2x6, 2x8, 2x10, or 2x12 at 1-1/2" on center - and fastened together with nails. NLT is sanctioned by building codes and qualifies as Heavy Timber.

15 What about other species? PRG 320 lays out the path Hardwood structural lumber Previous and current research Non-building markets

16 Cooperative effort by Michigan Tech, USDA Forest Service, University of Minnesota Duluth, Northern Hardwoods Fundamental properties Manufacturing--sorting, grading and properties of hardwood industrial materials (logs, veneer, lumber) Engineered products - trusses, I-joists, laminated veneer lumber, glulam

17 WVU: Developing Low-Grade Hardwood CLTs Development of CLT panels using low-value, low-quality hardwoods (e.g., Red Maple, Yellow-poplar, Beech, etc.) Full Length Panels Dr. David DeVallance Production of 10-foot Panels WVU HRT and USDA WERC Grant Project
