Laminated veneer lumber detail. Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives.It is typically used for headers, beams, rimboard, and edge-forming material.
For example, at 150 °F, using the Arden Buck equation, the saturation vapor pressure of water is found to be about 192 mmHg (25.6 kPa). The time constant for drying a 1-inch-thick (25 mm) red oak board at 150 °F is then τ = 3.03 {\displaystyle \tau =3.03} days, which is the time required to reduce the moisture content to 1/e = 37% of its ...

Different types of wood warping. Wood warping is a deviation from flatness in timber as a result of internal residual stress caused by uneven shrinkage. Warping primarily occurs due to uneven expansion or contraction caused by changes in moisture content.
Ancient Egyptian woodworking. There is significant evidence of advanced woodworking in ancient Egypt. [1] Woodworking is depicted in many extant ancient Egyptian drawings, and a considerable amount of ancient Egyptian furniture (such as stools, chairs, tables, beds, chests) have been preserved.
Eusideroxylon are canopy tree species with erect or spreading branches and extremely durable and decay-resistant wood.. Eusideroxylon zwageri is a slow growing (0.5 metres per year) [4] [5] tall evergreen tree with a straight bole (usually host to Cassytha, a parasitic vine with leaves reduced to scales, up to half of the tree's height).
Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.
