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.

Cementitious foam insulation is a cement-based thermal and acoustic insulation, [1] with an R-value similar to that of fiberglass. [2] It is installed as a foam with a consistency like shaving cream, [2] or as pre-cast slabs. [3] The current cost is similar to that of polyurethane foams. [2]
