OSB is frequently used in light steel frame house construction. OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. [2] It is now more popular than plywood, commanding 66% of the North American structural panel market. [3]
EPS is the most common of the foams used and has an R-value (thermal resistance) of about 4 °F·ft 2 ·h/Btu (equivalent to about 0.7 K·m 2 /W) per 25 mm thickness, which would give the 3.5 inches (89 mm) of foam in a 4.5-inch-thick (110 mm) panel an R value of 13.8 (caution: extrapolating R-values over thickness may be imprecise due to non ...
Plywood and OSB typically have a density of 560–640 kg/m 3 (35–40 lb/cu ft). For example, 9.5 mm (3 ⁄ 8 in) plywood sheathing or OSB sheathing typically has a surface density of 4.9–5.9 kg/m 2 (1–1.2 lb/sq ft). [51] Many other engineered woods have densities much higher than OSB.

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 ...
While plywood became widespread by the early 20th century, the invention of LVL was not until the 1980s after the invention of oriented strand board. [3] The American Wood Council's National Design Specification for Wood Construction is generally updated on a 3- to 5-year cycle. The 1991 release is the first release which mentions LVL.
The boards are placed in a press where the press will press down on the boards with roughly 2.8 megapascals (400 psi) of pressure. [3] At the same time, the boards will also be heated up to 149 °C (300 °F)—this heat and pressure cause the adhesive to cure, forming the finished board.
APA – The Engineered Wood Association is the nonprofit trade association of the U.S. and Canadian engineered wood products industry. Based in Tacoma, Washington, the Association is composed of and represents manufacturers of structural plywood, oriented strand board (OSB), cross-laminated timber, glued laminated (glulam) timber, wood I-joists, laminated veneer lumber (LVL) and other ...
