Medium-density fibreboard. Medium-density fibreboard ( MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [ 1] MDF is generally denser than plywood.
The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1. The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution ...
A sawmill ( saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes ( dimensional lumber ). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
Flitch beam. A flitch beam (or flitched beam) is a compound beam used in the construction of houses, decks, and other primarily wood-frame structures. Typically, the flitch beam is made up of a vertical steel plate sandwiched between two wood beams, the three layers being held together with bolts. In that common form it is sometimes referenced ...
Lumber is a sustainable and environmentally friendly construction material that could replace modern building materials (e.g. concrete and steel) given its structural performance, capacity to fixate CO 2 and low energy demand during the manufacturing process. [47] Substituting lumber for concrete or steel avoids the carbon emissions of those ...
Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.

Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. 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 ...
It is an engineered woodfrom the family of manufactured boards, which include plywood, medium-density fibreboard(MDF), oriented strand board(OSB), and particle board(or chipboard). All plywoods bind resin and wood fibre sheets (cellulosecells are long, strong and thin) to form a composite material.
