Glass brick has an r value between 1.75 and 1.96, close to that of thermopane windows. [ 1 ] [ 2 ] There are newer glass blocks injected with argon gas and having a layer of low-emissivity glass between the halves, which increases the insulative (U) value to 1.5 W/m 2 ·K, which is between triple glazed windows (1.8 W/m 2 ·K) and specialty ...
The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a material (e.g., for polyethylene foam), or for an assembly of materials (e.g., a wall or a window). In the case of materials, it is often expressed in terms of R ...
Vacuum Insulating Glass (VIG) units result in R-values as high as R-15 (center of glass). Combining a VIG unit with another glass pane and warm edge spacer result in R-18 (center of glass) or more depending upon the low-e coating(s). Double VIG units with warm edge spacer reach R-25 (center of glass) or more depending upon low-e coatings and ...
Renovation brings U g value of 0,29 W/(m 2 K) [R-value 20. Quadruple glazing (quadruple-pane insulating glazing) is a type of insulated glazing comprising four glass panes, commonly equipped with low emissivity coating and insulating gases in the cavities between the glass panes. Quadruple glazing is a subset of multipane (multilayer) glazing ...

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.
