High Humidity reduces mechanical damage such as brittle paint but raises the risks of biological organisms, e.g. white efflorescence and green-to-black stains on a panel painting. [12] High Humidity also raises the risks of curving or warping of the wood over time, forcing the paint to flake off.
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard).
Glulam brace with plates used for connections Glulam frame of a roof structure. 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.
Thermal insulation – CLT panels provide air tightness and great thermal insulation to buildings as the thermal conductivity (U) of a panel is approximately 0.3458 W/m 2 K. [18] Other common building materials can have U values ranging from 0.4 to 2.5 W/m 2 K. [19] The various layers of wood also serve as a thermal mass, which can help reduce ...
Particle board is cheaper, denser, and more uniform than conventional wood and plywood and is substituted for them when cost is more important than strength and appearance. Particleboard can be made more appealing by painting or the use of wood veneers on visible surfaces. Though it is denser than conventional wood, it is the lightest and ...
The design strength of PSL is greater than that of sawn lumber as the strands are glued together directionally and under high pressure. This results in a much denser and stronger material. Because knots and other imperfections are randomly dispersed throughout the product (and filled up and fortified with glue) strength variability from one ...

Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
