Cross Laminated Timber • A CLT panel consists of:
– Several layers of kiln-dried lumber boards stacked in alternating directions
– bonded with structural adhesives – Pressed to form a solid, straight, rectangular panel.
• CLT panels consist of an odd number of layers and may be sanded or prefinished before shipping
• CLT panels are cut to size, including door and window openings
Items to consider
• What is your CLT market ? • Grade of CLT you would like to produce? • Sizing of your panels to meet your market • Sizing of raw materials for layup • Open vs close time (Type of Glue) • Manual or Automated • Start with big footprint or smaller
This will define your plant layout
TYPE of CUSTOMER
Are you a wood producer? – Sawmill – Dry kilns – Planer Mill
Are you a engineered wood Supplier? – LVL – Laminated Beam – OSB – Plywood – ETC..
Wood Producer
How Could Your Sawmill Change • Primary
– Log bucking does it change your lengths – Primary does it change the products you target
• Secondary – Optimization at the edger and the trimmer as visual grades will
play a role • Drying
– Moisture Content 10-12% mc • Planer mill
– Number of sorts – Square edge lumber
Remember
• Sawmilling is a destructive process – You make your money efficiently breaking
your log in to the correct product at the correct time. (Recovery, yield)
• CLT, additive process – Building up a CLT panel from a raw
material.
ENGINEERED WOOD SUPPLIER
Sourcing your supply • Best way to handle incoming materials • Will the incoming material require
regrading • Will the material require resizing or
shaping • You are currently using glue will it be
the same glue
OPEN – CLOSED Time
There are one part and two part glues available The type of glue you select will determine the production a press line can produce Typically 2:1 or 3:1
