In 1939, the U.S. Navy Bureau of Ships made Owens-Corning insulation standard in new warship construction. Warship insulation, called Navy Board, was a permanent form-board insulation covered with woven continuous fiber cloth. Owens-Corning produced a prototype boat hull constructed of fiber glass-reinforced plastic in 1944. [11]

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 ...
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1] Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
