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.
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 ...
Founded in the 1960s by Eugene Murtagh, the company floated on the Irish Stock Exchange in 1989 with a value of IR£20m. [4] It expanded into insulated panels and rigid insulation boards via numerous greenfield plants and acquisitions, including the European insulation arm of CRH plc in 2010 [5] and the construction division of ThyssenKrupp Steel in 2012.

This means that VIPs have about one-fifth the thermal conductivity of conventional insulation, and therefore about five times the thermal resistance per unit thickness. Based on a typical k-value of 0.007 W/(m·K), the R-value of a typical 25-millimetre-thick (1 in) VIP would be 3.5 m 2 ·K/W (20 h·ft 2 ·°F/BTU). To provide the same R-value ...
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
Insulative paints, or insulating paints, are a specially designed type of paint in which can be used to coat a surface (e.g a wall) to reduce heat transfer as well as increase the thermal insulating property (R-value in order to aid cooling and heating efforts for example [1].
