  2. Glass brick - Wikipedia

    en.wikipedia.org/wiki/Glass_brick

    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 ...

  4. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    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 ...

  5. Insulated glazing - Wikipedia

    en.wikipedia.org/wiki/Insulated_glazing

    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 ...

    en.wikipedia.org/wiki/Glazing_(window)

    The ideal gap size varies by location, but on average it ranges from 15-18 mm thick, giving a final assembly size of 23-26 mm assuming a typical glazing thickness of 4 mm. [9] A double-paned window with air in the gap has an R-value of 2.1, which is much better than the 0.9 that a single pane of glass yields. A triple-paned window, which is not ...

    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 ...

    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.

  9. List of physical properties of glass - Wikipedia

    en.wikipedia.org/wiki/List_of_physical...

    Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
