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. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction.

Closed-cell foams are superior insulators. While open-cell foams typically have R-values of 3 to 4 per inch (RSI-0.53 to RSI-0.70 per inch), closed-cell foams can attain R-values of 5 to 8 per inch (RSI-0.88 to RSI-1.41 per inch). This is important if space is limited, because it allows a thinner layer of insulation to be used.
Styrofoam has a variety of uses. Styrofoam is composed of 98% air, making it lightweight and buoyant. [6] DuPont produces styrofoam building materials, including varieties of building insulation sheathing and pipe insulation. The claimed R-value of styrofoam insulation is approximately 5 °F⋅ft 2 ⋅h/BTU for 1 inch thick sheet. [7]
American 2016: Flexible insulation from Owens Corning includes faced and unfaced rolls of glass wool and with foil. [91] 1960s values: All thermal conductivities from Cypress to Maple are given across the grain. [92] Hydrogen: 0.1819 [93] 290 Hydrogen gas at room temperature. Ice: 1.6 [23]-2.1 [6]-2.2 [64]-2.22 [94] The Historic Ice Authorities ...
