  2. Superinsulation - Wikipedia

    en.wikipedia.org/wiki/Superinsulation

    There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m 2 ·K) respectively)

  3. R-value (insulation) - Wikipedia

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

    R. -value (insulation) 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. [3] R-value is the temperature difference per unit of heat flux needed to sustain one unit of ...

  4. Building insulation - Wikipedia

    en.wikipedia.org/wiki/Building_insulation

    By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, [1][2] especially when buildings are heated by oil, natural gas, or coal-based electricity.

  5. Multi-layer insulation - Wikipedia

    en.wikipedia.org/wiki/Multi-layer_insulation

    The metal coated plastic layers and the scrim separator are visible. Multi-layer insulation (MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, [1] MLI is one of the main items of the spacecraft thermal design, primarily intended to reduce ...

  6. Thermal transmittance - Wikipedia

    en.wikipedia.org/wiki/Thermal_transmittance

    Poorly insulated walls: 2 W/(m 2 ⋅K) Well-insulated floors: 0.2 W/(m 2 ⋅K) Poorly insulated floors: 1.0 W/(m 2 ⋅K) In practice the thermal transmittance is strongly affected by the quality of workmanship and if insulation is fitted poorly, the thermal transmittance can be considerably higher than if insulation is fitted well [3]

  7. Cork thermal insulation - Wikipedia

    en.wikipedia.org/wiki/Cork_thermal_insulation

    Cork thermal insulation refers to the use of cork as a material to provide thermal insulation against heat transfer. Cork is suitable as thermal insulator, as it is characterized by lightness, elasticity, impermeability, and fire resistance. In construction, cork can be applied in various construction elements like floors, walls, roofs, and ...
