Insulation
Revision as of 16:54, 12 August 2015 by J.williams (talk | contribs)
Insulation is material that isolates a physical property. Usually this refers to either:
- Electrical insulation which prevents electricity from going where it isn't wanted.
- Thermal insulation which prevents heat from going where it isn't wanted.
Often materials that make good electrical insulators also make good thermal insulation, but there are exceptions.
