Fiberboard, classified by ASTM C208, Standard Specification for Cellulosic Fiber Insulating Board, [3] has many benefits and is used in residential and commercial construction. Applications include: sound proofing/deadening; structural sheathing; low-slope roofing; sound deadening flooring underlayment
There are various styles of joining the pieces, from board and batton, where the butt joints between panels is covered with a thin strip (usually 25 to 50 mm wide) of wood, to a variety of clapboard, also called lap siding, in which planks are laid horizontally across the wall starting from the bottom, and building up, the board below ...
When manufacturing a panel with a polyurethane core pressure and heat are both generated from the expansion of the foam during the foaming process. The skins are set in a large clamping device which functions as a mold. The skins must be held apart from each other to allow the liquid polyurethane materials to flow into the device.
The use of highly compressed straw bales as insulation, though uncommon, is gaining popularity in experimental building projects for the high R-value and low cost of a thick wall made of straw. "Research by Joe McCabe at the Univ. of Arizona found R-value for both wheat and rice bales was about R-2.4 (RSI-0.42) per inch with the grain, and R-3 ...
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
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 ]
