The construction industry makes use of measures such as the R-value (resistance) and the U-value (transmittance or conductance). Although related to the thermal conductivity of a material used in an insulation product or assembly, R- and U-values are measured per unit area, and depend on the specified thickness of the product or assembly.

Standard Test Method for Electrical Indication of Concrete's Ability to Resist Chloride Ion Penetration. ASTM Standard C1202-10. Standard Test Method for Surface Resistivity of Concrete's Ability to Resist Chloride Ion Penetration. Washington, D.C., USA: American Association of State Highway and Transportation Officials. 2011. AASHTO TP 95.
The thermal transmittance of a material (such as insulation or concrete) or an assembly (such as a wall or window) is expressed as a U-value. The thermal insulance of a structure is the reciprocal of its thermal transmittance.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
The water vapour diffusion resistance of hemp concrete ranges from 5 to 25. [ 24 ] [ 29 ] Furthermore, between 2 and 4.3 g/ (m 2 %RH), it is considered an excellent moisture regulator. [ 28 ] [ 30 ] It can absorb relative humidity when there is a surplus in the living environment and release it when there is a deficit.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
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.
With a water vapour diffusion resistance factor of 5–54.61, [9] [10] cork materials have good hydric properties for moisture insulation. Fino et al. [11] investigated the thermal insulation of walls covered with medium density expanded cork panes. To determine the impact of moisture on heat transfer through the cork wall, they conducted a ...
