   en.wikipedia.org/wiki/Lumber

   For example, a "2×4" board historically started out as a green, rough board actually 2 by 4 inches (51 mm × 102 mm). After drying and planing, it would be smaller by a nonstandard amount. Today, a "2×4" board starts out as something smaller than 2 inches by 4 inches and not specified by standards, and after drying and planing is minimally 1 ...

   en.wikipedia.org/wiki/Building_material

   Cement bonded composites are made of hydrated cement paste that binds wood, particles, or fibers to make pre-cast building components. Various fiberous materials, including paper, fiberglass, and carbon-fiber have been used as binders. Wood and natural fibers are composed of various soluble organic compounds like carbohydrates, glycosides and ...

5. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction.

6. Sheet resistance - Wikipedia

   en.wikipedia.org/wiki/Sheet_resistance

   Sheet resistance is a special case of resistivity for a uniform sheet thickness. Commonly, resistivity (also known as bulk resistivity, specific electrical resistivity, or volume resistivity) is in units of Ω·m, which is more completely stated in units of Ω·m 2 /m (Ω·area/length).

7. Coating - Wikipedia

   X-ray photoelectron spectroscopy (XPS) is also a classical characterization method to investigate the chemical composition of the nanometer thick surface layer of a material. [65] Scanning electron microscopy coupled with energy dispersive X-ray spectrometry ( SEM-EDX , or SEM-EDS) allows to visualize the surface texture and to probe its ...
