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.
Vertical, metal furring is applied to the wall to create a channel and receive the siding material. In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, [1] or to increase the beam of a wooden ship.
Rigid panel insulation, also known as continuous insulation [13] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
The Energy Saving Ordinance (EnEV) 2013 clarified the requirement of thermal insulation of the ceiling. And it mentioned that if the ceiling was not fulfilled, thermal insulation will be needed in accessible ceilings over upper floor's heated rooms. [U-Value must be under 0.24 W/(m 2 ⋅K)] [32]
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.

Metal lathing was spaced across a 13.5-inch (340 mm) center, attached by tie wires using lathers' nippers. Sometimes, the mesh was dimpled to be self- furring . In use as early as 1900, rock lath (also known as "button board," "plaster board" or "gypsum-board lath"), is a type of gypsum wall board (essentially an early form of drywall) with ...
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 ...
Tin panels today are made in 24-by-24-inch (610 mm × 610 mm) and 24-by-48-inch (610 mm × 1,220 mm) sizes for easier handling and one-person installation. Today, most tin ceiling manufacturers actually use recycled blackplate steel in a thickness of only 0.010 inches (0.25 mm). There are some manufacturers who also use actual tin plated steel ...
