    Foil or "reflective foil laminate"s (RFL). Foil-faced polyurethane or foil-faced polyisocyanurate panels. Foil-faced polystyrene. This laminated, high density EPS is more flexible than rigid panels, works as a vapor barrier, and works as a thermal break. Uses include the underside of roof sheathing, ceilings, and on walls.

    en.wikipedia.org/wiki/Radiant_barrier

    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.

  4. Multi-layer insulation - Wikipedia

    en.wikipedia.org/wiki/Multi-layer_insulation

    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 heat loss by thermal radiation .

  5. Sarking - Wikipedia

    en.wikipedia.org/wiki/Sarking

    In modern usage of the term in Australia, sarking refers to a laminated aluminium foil layer, or reflective foil laminate (RFL), that is installed on the roof trusses, beneath the battens, supporting a tile or metal deck roof. It acts as additional radiative (radiant barrier) and convective insulation and provides a condensation barrier. [1]

  6. Low emissivity - Wikipedia

    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 ...

  7. Radiator reflector - Wikipedia

    en.wikipedia.org/wiki/Radiator_reflector

    Where a reflector foil also has some insulating ability against conduction (i.e. losses through the wall), it may have some useful effect. This is most pronounced when the wall itself has poor insulation performance: in a wall constructed to modern standards of insulation, even this effect may be reduced to a negligible benefit.
