2. Oriented strand board - Wikipedia

   en.wikipedia.org/wiki/Oriented_strand_board

   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

3. Flat roof - Wikipedia

   en.wikipedia.org/wiki/Flat_roof

   Roof decking is usually of plywood, chipboard or oriented strand board (OSB, also known as Sterling board) of around 18mm thickness, steel or concrete. The mopping of bitumen is applied in two or more coats (usually three or four) as a hot liquid, heated in a kettle.

4. Engineered wood - Wikipedia

   en.wikipedia.org/wiki/Engineered_wood

   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). [50] Many other engineered woods have densities much higher than OSB.

5. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   Structural insulated panel. SIPs are most commonly made of OSB panels sandwiched around a foam core made of polystyrene. A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used as a building material in the construction industry. SIP is a sandwich structured composite, consisting of an insulating ...

6. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   Another method of applying a radiant barrier to a roof in new construction is to use a radiant barrier that is pre-laminated to OSB panels or roof sheathing. Manufacturers of this installation method often tout the savings in labor costs in using a product that serves as roof decking and radiant barrier in one.

7. Plywood - Wikipedia

   en.wikipedia.org/wiki/Plywood

   Plies vary in thickness from 1.4 mm to 4.3 mm. The number of plies—which is always odd—depends on the thickness and grade of the sheet. Roofing can use the thinner 16-millimetre (5 ⁄ 8 in) plywood. Subfloors are at least 19 millimetres (3 ⁄ 4 in) thick, the thickness depending on the distance between floor joists.

8. Rim joist - Wikipedia

   en.wikipedia.org/wiki/Rim_joist

   In dimensioned lumber construction, the rim joists are the same depth, thickness and material as the joists themselves; in engineered wood construction, the rim joists may be oriented strand board (OSB), plywood or an engineered wood material varying in thickness from 1 inch (25 mm) to as much as 1 + 3 ⁄ 4 inches (44 mm), though they are ...

9. Lumber - Wikipedia

   en.wikipedia.org/wiki/Lumber

   This "quarter" system is rarely used for softwood lumber; although softwood decking is sometimes sold as 5/4, even though it is actually one inch thick (from milling 1 ⁄ 8 in or 3.2 mm off each side in a motorized planing step of production). The "quarter" system of reference is a traditional North American lumber industry nomenclature used ...
