Although longitudinal diffusion is most rapid, it is of practical importance only when short pieces are dried. Generally the timber boards are much longer than in width or thickness. For example, a typical size of a green board used for this research was 6 m long, 250 mm in width and 43 mm in thickness. If the boards are quartersawn, then the ...
Timber-framed structures differ from conventional wood-framed buildings in several ways. Timber framing uses fewer, larger wooden members, commonly timbers in the range of 15 to 30 cm (6 to 12 in), while common wood framing uses many more timbers with dimensions usually in the 5- to 25-cm (2- to 10-in) range.
A plank is timber that is flat, elongated, and rectangular with parallel faces that are higher and longer than wide. [1] Used primarily in carpentry, planks are critical in the construction of ships, houses, bridges, and many other structures. [2] Planks also serve as supports to form shelves and tables.

Cross-laminated timber (CLT) is an engineered wood product that is gaining popularity in the construction industry due to its numerous advantages, such as sustainability, cost-effectiveness, and ease of construction. Mechanical properties, particularly compressive strength, are key factors to consider when designing and constructing CLT panels.
EN 1995-1-2 deals with the design of timber structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1995-1-1 and EN 1991-1-2:2002. EN 1995-1-2 only identifies differences from, or supplements normal temperature design and deals only with passive methods of fire protection.
Shakes may reduce the strength of a timber and the appearance thus reduce lumber grade and may capture moisture, promoting decay. Eastern hemlock is known for having ring shake. [32] A "check" is a crack on the surface of the wood caused by the outside of a timber shrinking as it seasons. Checks may extend to the pith and follow the grain. Like ...
Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.
The timber would be typically called battens (7 inches wide), deals (above 7, usually 9 inches wide) and planks (11 inches wide); boards were under 2 inches thick. [3] [4] The standard hundred of the Russian capital of Saint Petersburg was 120 boards which were 12 feet long, 1 1 ⁄ 2 inches thick and 11 inches wide – a volume of 165 cubic ...
