[4] [5] The panels were used for the exterior of field hospitals and military housing in France during WWI. [4] By 1925, car manufacturers switched to canvas tops and Agasote lost sales, so the company heavily promoted Homasote for its versatility and insulation properties. The company then changed its name to Homasote after its now largest ...
It acts as additional radiative (radiant barrier) and convective insulation and provides a condensation barrier. [1] In New Zealand, both corrugated metal and asbestos-cement shingle roofs were fitted directly over wooden sarking boards in the historical "bungalow" style of house construction. [2] [3]
Wood wool composite boards (WW-C boards) are a two- or three-layer combination of wood wool boards and various insulation materials (mineral fibre boards, EPS boards, XPS boards, etc…) The thickness of the wood wool layer in a composite board is at least 5 mm. Due to the higher insulation effect of the mineral or synthetic insulation layer ...
Hollow-core slabs are used when there is a need for flushed ceiling. T-beams are similar to double tees but can be used for span ranging from 30 feet (9.1 m) to 100 feet (30 m). Joists and planks are combination of using prestressed joists with prestressed planks.
Magnesium oxide wallboard (10 mm thickness) Magnesium oxide, more commonly called magnesia, is a mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction.
This 5 ⁄ 16 inch (7.9 mm) thick cement board is designed as an underlayment for tile floors. These are 3-by-5-foot (91 by 152 cm) sheets. These are 3-by-5-foot (91 by 152 cm) sheets. A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. [ 1 ]
EPS is the most common of the foams used and has an R-value (thermal resistance) of about 4 °F·ft 2 ·h/Btu (equivalent to about 0.7 K·m 2 /W) per 25 mm thickness, which would give the 3.5 inches (89 mm) of foam in a 4.5-inch-thick (110 mm) panel an R value of 13.8 (caution: extrapolating R-values over thickness may be imprecise due to non ...
Hardboard is similar to particle board and medium-density fiberboard, but is denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed. [ 3 ] The density of hardboard is higher than 500 kg/m 3 (31 lb/cu ft), [ 4 ] usually about 800–1,040 kg/m 3 (50–65 lb/cu ft). [ 5 ]
