2. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   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 ...

3. Oriented strand board - Wikipedia

   en.wikipedia.org/wiki/Oriented_strand_board

   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]

4. Oriented structural straw board - Wikipedia

   en.wikipedia.org/wiki/Oriented_structural_straw...

   OSSB can replace wood oriented strand board (OSB) and particle board in structural and non-structural applications, such as interior and exterior walls for house construction, furniture and interior decoration.

5. Plywood - Wikipedia

   en.wikipedia.org/wiki/Plywood

   Plywood was introduced into the United States in 1865 [7] and industrial production there started shortly after. In 1928, the first standard-sized 4 ft by 8 ft (1.22 m by 2.44 m) plywood sheets were introduced in the United States for use as a general building material. [4]

6. 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). [51] Many other engineered woods have densities much higher than OSB.

7. Louisiana-Pacific - Wikipedia

   en.wikipedia.org/wiki/Louisiana-Pacific

   In 1979, the company bought fifteen building-material centers in southern California from Lone Star Industries, which provided LP with much needed distribution centers. [1] In the late 1970s, the company began manufacturing oriented strand board (OSB) by slicing logs into wafers, mixing the wafers with resin, and then pressing them into sheets. [4]

8. Glued laminated timber - Wikipedia

   en.wikipedia.org/wiki/Glued_laminated_timber

   Glulam brace with plates used for connections Glulam frame of a roof structure. Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.

9. Laminated veneer lumber - Wikipedia

   en.wikipedia.org/wiki/Laminated_veneer_lumber

   It is typically used for headers, beams, rimboard, and edge-forming material. LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform. Due to its composite nature, it is much less likely than conventional lumber to warp, twist, bow, or shrink.
