Plywood for flooring applications is often tongue and groove (T&G); This prevents one board from moving up or down relative to its neighbor, providing a solid-feeling floor when the joints do not lie over joists. T&G plywood is usually found in the 13-to-25-millimetre (1 ⁄ 2 to 1 in) range.
That followed Home Depot's 0.3% drop in comparable sales for the fourth quarter, the company reported February 21. ... And though lumber prices have fallen sharply, the firm noted for many "core ...
Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. The maximum temperature jump, , sustainable by a material can be defined for strength-controlled models by: [4] [3] = where is the failure stress (which can be yield or fracture stress), is the coefficient of thermal expansion, is the Young's modulus, and is a constant ...
The Weyerhaeuser Company (/ ˈ w ɛər h aʊ z ə r / WAIR-how-zər) is an American timberland company which owns nearly 12,400,000 acres (19,400 sq mi; 50,000 km 2) of timberlands in the U.S., and manages an additional 14,000,000 acres (22,000 sq mi; 57,000 km 2) of timberlands under long-term licenses in Canada.

The creation of pressed wood begins with the veneers [2] being placed in a rotary dryer. [3] This dryer is typically heated with steam at around 204 °C (400 °F). This process prepares the veneers for the humidifying process in which the veneers are then placed into humidification chambers.
In several wood related industries, such as plywood, veneer and laminated veneer industries, the logs, before debarking them, are submerged in warm water to ease the debarking process. [5] The process conditions (temperature and time) depend on the country, company, wood species and their properties.
Woody plants, both true wood from trees and such plants as palms and bamboo, yield natural composites that were used prehistorically by humankind and are still used widely in construction and scaffolding. Plywood, 3400 BC, [11] by the Ancient Mesopotamians; gluing wood at different angles gives better properties than natural wood.
Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. [1] It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface.
