insulating
UK: ˈɪnsjʊleɪtɪŋ | US: ˈɪnsəleɪtɪŋ
adj. serving to prevent the passage of heat, electricity, or sound
v. (present participle of insulate) protecting something by surrounding it with material that reduces heat, electricity, or sound transfer
The word insulating derives from the Latin insula (island), metaphorically extended to mean "isolated." The verb insulate emerged in the 16th century, originally meaning "to make into an island" (literal isolation), later shifting to its modern technical sense of blocking energy transfer (thermal/electrical isolation). The suffix -ing marks its present participle form, turning it into an adjective or continuous verb.
