Wooden materials
Definition of term
The term engineered wood comprises various products that are manufactured through taking apart wood and subsequent joining it together, mostly under pressure and addition of other materials (for example synthetic resins, mineral binding agents and other additives). Among the wooden materials are primarily the materials in the form of boards (plywood, chipboard) as well as the correspondingly built formed parts of plywood, shavings or fibres. The advantages of the wooden materials compared with solid wood are particularly the homogeneous structure and thus the more steady behaviour, the availability of larger dimensions and the higher utilisation of raw material.
Lumber (also known as timber) is wood in any of its stages from felling to readiness for use as structural material for construction.
[Tarcica] A plank is a piece of timber that is flat, elongated and rectangular, with parallel faces, higher or longer than wide, used in carpentry and the construction of ships, houses, bridges and other structures.[1]
[forniry] Veneer refers to thin slices of wood, usually thinner than 5 mm, that typically are glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture.
[Plyta stolarska]Blockboard is a wood based panel, made up of a core of softwood strips glued together. The strips may be up to about 28mm wide and are placed edge to edge and sandwiched between veneers of softwood, hardwood or thin MDF or particleboard, glued under high pressure.
The internal strips are generally made of light weight poplar wood or spruce.
Blockboard is used to make doors, tables, shelves, paneling and partition walls.
Blockboard panels are produced in 3-layers, with one veneer sheet (or thin MDF or particlebaord) covering each side, or 5-layers with two veneer sheets per side for better stability.
[sklejka]Plywood
is composed of at least three plies of wood glued on top of each other, The outer and inner layers are poplar veneer sheets. They are symmetrically cross-bonded. whereat the directions of fibre of adjacent plies are staggered by 90°.
[plyta wiórowa] Chipboard
is produced through pressing of wood shavings and/or other fibres of wooden kind (for example shives of hemp or flax) with organic adhesives (synthetic resins) or with mineral binders (for example gypsum, cement). The gross density is between 480 - 750 kg/m³.
[płyta paździerzowa/pilśniowa] Beaverboard (also beaver board) is a light wood-like building material, formed of wood fibre compressed into sheets.
[materialy podlogowe] Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material due to its environmental profile, durability, and restorability
Solid hardwood floors are made of planks milled from a single piece of timber. Solid hardwood floors were originally used for structural purposes, being installed perpendicular to the wooden support beams of a building known as joists or bearers. With the increased use of concrete as a subfloor combined with solid wood's inability to be installed directly over concrete, solid wood floors are now used almost exclusively for their appearance.
Planks are usually made from sawn timber, more than 38 mm thick, and are generally wider than 63 mm. If the width is less than 63 mm and the thickness less than 38 mm is called board.
Wooden pavement is produced from cut rounded timber of 50 mm in height, and 80-140 mm in diameter. It is treated with special antiseptic protecting against weather conditions, insects and improving general physical features.
Wooden pavement owns several advantages. Firstly, it is ecologically compatible corresponding to all requirements, and secondly, it hinders water accumulation in your yard and does not require installation of any special sewage disposal structures.
