  2. Aluminium foil - Wikipedia

    en.wikipedia.org/wiki/Aluminium_foil

    Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products, and 25% is used for industrial applications (e.g., thermal insulation, electrical cables, and electronics). [2] It can be easily recycled. Aluminium foil supplanted tin foil in the mid 20th century.

  3. List of insulation materials - Wikipedia

    en.wikipedia.org/wiki/List_of_insulation_materials

    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.

  4. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Reflective aluminum foil is the most common material used as a radiant barrier. It has no significant mass to absorb and retain heat. It also has very low emittance values "E-values" (typically 0.03 compared to 0.90 for most bulk insulation) which significantly reduces heat transfer by radiation.

  5. R-value (insulation) - Wikipedia

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

    In most countries the properties of specific materials (such as insulation) are indicated by the thermal conductivity, sometimes called a k-value or lambda-value (lowercase λ). The thermal conductivity (k-value) is the ability of a material to conduct heat; hence, the lower the k-value, the better the material is for insulation.

  6. List of thermal conductivities - Wikipedia

    en.wikipedia.org/wiki/List_of_thermal_conductivities

    These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.

  7. Thermal insulation - Wikipedia

    en.wikipedia.org/wiki/Thermal_insulation

    Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1] Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.

  8. Low emissivity - Wikipedia

    en.wikipedia.org/wiki/Low_emissivity

    As it is an opaque material, the remaining 10 percent must be reflected. Conversely, a low-e material such as aluminum foil has a thermal emissivity/absorptance value of 0.03 and as an opaque material, the thermal reflectance value must be 1.0 - 0.03 =0.97, meaning it reflects 97 percent of radiant thermal energy. Low-emissivity building ...

  9. Polyisocyanurate - Wikipedia

    en.wikipedia.org/wiki/Polyisocyanurate

    PIR is typically produced as a foam and used as rigid thermal insulation. Its thermal conductivity has a typical value of 0.023 W/(m·K) (0.16 BTU·in/(hr·ft 2 ·°F)) depending on the perimeter:area ratio. [3] PIR foam panels laminated with pure embossed aluminium foil are used for fabrication of pre-insulated duct that is used for heating ...
