A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems, by providing pathways for either heated/conditioned or return airflows, usually at greater than atmospheric pressure.
In LVL, the direction of the wood grain is always parallel to the length of the billet. [6] The stacking of these veneers into a complete board, called a billet, creates a single piece of LVL sharing a common direction of wood grain. [1] LVL is typically rated by the manufacturer for elastic modulus and allowable bending stress.
The building envelope or enclosure is all of the elements of the outer shell that maintain a dry, heated, or cooled indoor environment and facilitate its climate control.
The plenum generally sits 0.3 and 0.46 metres (12 and 18 in) above the structural concrete slab, although lower heights are possible. [ 6 ] [ 7 ] Specially designed floor diffusers are used as the supply outlets. [ 5 ]
Wall studs are framing components in timber or steel-framed walls, that run between the top and bottom plates.It is a fundamental element in frame building. The majority non-masonry buildings rely on wall studs, with wood being the most common and least-expensive material used for studs.
In Europe, the cell size in the suspension grids is 600×600 mm, while the ceiling tiles and fixtures are slightly (5 mm) smaller at 595×595 mm or 595×1195 mm, and the T5 fluorescent and LED tubes are shorter by 37 mm to allow for easier and safer insertion and removal without breakage.

The wood moisture content is above 25% on a dry-weight basis; The environment is sufficiently warm; Oxygen (O 2) is present; Wood with less than 25% moisture (dry weight basis) can remain free of decay for centuries. Similarly, wood submerged in water may not be attacked by fungi if the amount of oxygen is inadequate. Fungi lumber/timber ...
