Vertical, metal furring is applied to the wall to create a channel and receive the siding material. In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, [1] or to increase the beam of a wooden ship.
The SI derived unit for sectional density is kilograms per square meter (kg/m 2). The general formula with units then becomes: / = where: SD kg/m 2 is the sectional density in kilograms per square meters; m kg is the weight of the object in kilograms
Battens are also used in metal roofing to secure the sheets called a batten-seam roof and are covered with a batten roll joint. [2] Some roofs may use a grid of battens in both directions, known as a counter-batten system, which improves ventilation. Roofing battens are most commonly made of wood or metal, but can be made of other materials.
Fabric "weight" is often specified as mass per unit area, grams per square meter (gsm) or ounces per square yard. It is also sometimes specified in ounces per yard in a standard width for the particular cloth. One gram per square meter equals 0.0295 ounces per square yard; one ounce per square yard equals 33.9 grams per square meter.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic. If brick is being used on the exterior, then a vented air space may already be present, and furring strips are not necessary.
The American standard for transfer volume is a billion cubic microns per square inch, typically written as BCM / in 2, BCM/sq in, or BCM. A cubic micron (μm 3) is a unit of volume and one billion cubic microns (1 000 000 000 μm 3) is equal to 0.001 cm 3. Since one square meter is equal to 1550 square inches, it follows that 1 BCM/in 2 = 1.55 ...
Although the concept of U-value (or U-factor) is universal, U-values can be expressed in different units. In most countries, U-value is expressed in SI units, as watts per square metre-kelvin: W/(m 2 ⋅K) In the United States, U-value is expressed as British thermal units (Btu) per hour-square feet-degrees Fahrenheit: Btu/(h⋅ft 2 ⋅°F)
