Morphology
insulation = insulate (transparent) = insulat + ion
This sense names the action/process expressed by the verb 'insulate', a direct and regular nominalization.
Etymology
Insulation comes from the Latin word insula, meaning 'island', and is the same root as insulate. Imagine surrounding something so it becomes an 'island' against heat or noise, so insulation is the act of protecting by keeping unwanted heat, sound, or electricity away.
