   It is available in multiple thicknesses and comes in sheets 4 by 8 feet (1.2 by 2.4 m). [ 2 ] [ 3 ] The Homasote Company operates a 750,000-square-foot (70,000 m 2 ) factory in the West Trenton section of Ewing Township, New Jersey .

3. Plywood - Wikipedia

   en.wikipedia.org/wiki/Plywood

   The sizes of the most commonly used plywood sheets are 4 by 8 feet (1,220 mm × 2,440 mm) [20] which was first used by the Portland Manufacturing Company, who developed modern veneer core plywood for the 1905 Portland World Fair. A common metric size for a sheet of plywood is 1200 × 2400 mm. 5 × 5 feet (1,500 × 1,500 mm) is also a common ...

4. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   Typical U.S. height for panels is 8 or 9 feet (2.4 or 2.7 m). Panels come in widths ranging from 4 to 12 inches (100–300 mm) thick and a rough cost is $4–$6/ft 2 in the U.S. [5] In 4Q 2010, new methods of forming radius, sine curve, arches and tubular SIPs were commercialized. Due to the custom nature and technical difficulty of forming and ...

5. Oriented strand board - Wikipedia

   en.wikipedia.org/wiki/Oriented_strand_board

   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. For exterior wall applications, panels are available with a radiant-barrier layer laminated to one side; this eases installation and increases energy performance of ...

6. Roof shingle - Wikipedia

   en.wikipedia.org/wiki/Roof_shingle

   Roof shingles, like other building materials on vernacular buildings, are typically of a material locally available. The type of shingle is taken into account before construction because the material affects the roof pitch and construction method: Some shingles can be installed on lath where others need solid sheathing (sheeting) on the roof deck.

7. Purlin - Wikipedia

   en.wikipedia.org/wiki/Purlin

   The purlins are the large beams perpendicular to the rafters; from this shot, it appears that there are three purlins on either side of the roof. The sheathing boards are sometimes called the roof deck and are painted white. A purlin (or historically purline, purloyne, purling, perling) is a longitudinal, horizontal, structural member in a roof.

8. Domestic roof construction - Wikipedia

   en.wikipedia.org/wiki/Domestic_roof_construction

   A warm roof is a roof that is not ventilated, [9] where the insulation is placed in line with the roof pitch. [10] A hot roof is a roof designed not to have any ventilation and has enough air-impermeable insulation in contact with the sheathing to prevent condensation [ 11 ] such as when spray foam insulation is applied directly to the under ...

9. Shear wall - Wikipedia

   en.wikipedia.org/wiki/Shear_wall

   A typical timber shear wall consists of braced panels in the wall line, constructed using structural plywood sheathing, specific nailing at the edges, and supporting framing. A shear wall is an element of a structurally engineered system that is designed to resist in- plane lateral forces, typically wind and seismic loads.
