Engineered Lumber

Oriented Strand Board (OSB) OSB is manufactured from

waterproof heat-cured adhesives and rectangular shaped wood strands that are arranged in cross-oriented layers, similar to plywood.

Produced in huge, continuous mats, OSB is a solid panel product of consistent quality with no

laps, gaps or voids.

OSB Applications OSB is widely used in residential and commercial construction Also innovative features such as a slip-resistant texture to

panels designed for roof sheathing can be added. Benefits OSB panels can be manufactured from a wide range of fast-

growing species and from relatively small trees. utilizes a maximum amount of wood fiber from each tree that is

harvested

Plywood Manufactured from thin

sheets of cross-laminated veneer (To overlay or plate with a thin layer of wood )

bonded under heat and pressure with strong adhesives,.

Plywood A Wide Range of Products available in different grades ranging from smooth, natural

surfaces suitable for finish work also commonly used for wall sheathing and subfloors.

More than a dozen common thickness Over twenty different grades

LVL (Laminated Veneer Lumber)

Laminated veneer lumber (LVL) is an engineered wood product created by layering dried and graded wood veneers with waterproof adhesive into blocks of material known as billets.

Cured in a heated press,                                                                                 

LVL The grain of each layer of veneer runs in the same direction, rather than

cross-lamination which is typical of other engineered wood products such as plywood.

Benefits The resulting parallel-laminated lumber out-performs conventional lumber LVL is a solid, highly predictable and uniform engineered wood product

that is sawn to consistent sizes. Is virtually free from warping and splitting. Strong, Reliable and Consistent gluing process enables large timbers to be made from relatively small

trees of many species.

I-Joists

"I"-shaped engineered wood structural members

offer strength, versatility Used in residential and light

commercial applications. I-joists are comprised of top

and bottom flanges of various widths, united with webs of various depths.

The flanges resist common bending stresses, and the web provides uniform stability.

I-Joists What they can be made of I-joists can be manufactured using solid sawn lumber or

structural composite lumber for the flange components Plywood or oriented strand board can be used for the web. Benefits They are ideal for long spans Readily available from most builder supply sources Strength and versatility

Glued Laminated Timber (Glulam)

Glulam (Glued laminated timber) is a stress-rated engineered wood product comprised of wood laminations, that are bonded together with strong, waterproof adhesives.

Glued Laminated Timber Used in residential construction to large commercial projects Glulam has greater strength and stiffness than comparable

dimensional lumber. Benefits competitive cost Pound for pound, it’s stronger than steel. glulam beams can span long distances with minimal need for

intermediate supports. Flexibility with design Glulam components can be a variety of species,

Timberstrand Timberstrand LSL (Laminated

Strand Lumber) Made of fast-growing aspen

and yellow poplar Used for a broad range of

applications, such as Rim Board, window headers, wall studs and door headers.

Timberstrand Timberstrand Wall Studs are second to none in quality and

dimensional uniformity. Used often in areas of visual importance like family rooms with

tall walls, kitchens and hallways.  Engineered studs are available in many conventional sizes and

even long lengths for tall walls.

Benefits resists swelling from air-moisture level changes Comes in wide variety of sizes Great in all weather conditions

Particleboard is made from wood

particles, which are often the residue from other wood processing operations, combined under heat and pressure with a water resistant binder.

Particleboard additives can be incorporated to provide greater

dimensional stability Widely used in the manufacturing of furniture, cabinets,

floor underlayment, laminate flooring, stair treads, shelving and many other products.

Benefits Today's particleboard gives industrial users the

consistent quality and design flexibility needed for fast, efficient production lines

Particleboard panels are manufactured in a variety of sizes and densities

Environmental Benefits of Engineered Lumber

Efficient because they utilize more of the available resources with minimal waste.

Produced using faster growing and underutilized wood species from managed forests,

Reduce the industry's reliance on Old-Growth forests.
