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] The most common uses are as sheathing in walls, flooring, and roof decking
A shingle is the generic term for an individual roofing unit that is applied with other such units in an overlapping fashion. [2] Wood shingle, shingles sawn from bolts of wood such as red cedar which has a useful performance life expectancy of up to 30 years. However, young growth red cedar has a short life expectancy and high cost.
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).
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.
OSSB panels have high structural strength, load bearing and stability in both directions, as well as superior workability and excellent nail holding properties on all sides. Water permeability treated OSSB panels are more water resistant than treated traditional wood panel boards because they have no internal gaps or voids.
The building was dismantled in 1978, and most of the panels retained their original strength with the exception of paperboard, which is unsuited to outdoor exposure. Panels consisting of polystyrene core and paper overlaid with plywood skins were used in a building in 1967, and as of 2005 the panels performed well.
This is a list of building materials. Many types of building materials are used in the construction industry to create buildings and structures . These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects .
In rural Scandinavia, wood shingles were a common roofing material until the 1950s. [disputed – discuss] Wood shingles are susceptible to fire and cost more than other types of shingle so they are not as common today as in the past. Distinctive shingle patterns exist in various regions created by the size, shape, and application method.
