    Reflective foils are fabricated from aluminum foils with a variety of backings such as roofing paper, craft paper, plastic film, polyethylene bubbles, or cardboard. Reflective bubble foil is basically a plastic bubble wrap sheet with a reflective foil layer and belongs to a class of insulation products known as radiant foils.

    en.wikipedia.org/wiki/Low_emissivity

    Reflective thermal insulation is typically fabricated from aluminum foil with a variety of core materials such as low-density polyethylene foam, polyethylene bubbles, fiberglass, or similar materials. Each core material presents its own set of benefits and drawbacks based on its ability to provide a thermal break, deaden sound, absorb moisture ...

    en.wikipedia.org/wiki/Building_insulation

    In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmental investment for buildings.

    en.wikipedia.org/wiki/Building_insulation_material

    Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.

  6. Radiator reflector - Wikipedia

    en.wikipedia.org/wiki/Radiator_reflector

    The effect of placing a 10mm combined insulation and reflection behind radiators is about the same as that of 15mm insulation without a reflective layer. When the wall thickness behind the radiator is at minimum 1980 German standards this will reduce total heat losses of a building by about 4%.

  7. Emissivity - Wikipedia

    en.wikipedia.org/wiki/Emissivity

    Reflections (like on the blank end of the can and the countertop) make accurate measurements of reflective surfaces impossible. Temperature measurements Pyrometers and infrared cameras are instruments used to measure the temperature of an object by using its thermal radiation; no actual contact with the object is needed. The calibration of ...
