2. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   Research has shown that the insulation value of reflective bubble foil insulations and radiant barriers can vary from RSI 0 (R-0) to RSI 0.62 (R-3.5) per thickness of material. A study conducted by CMHC (Canada Mortgage & Housing Corporation) on four homes in Paris, ON found that the performance of the bubble foil was similar to an uninsulated ...

3. 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.

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. 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.
