Insulation" refers to a material or technique used to reduce the transfer of heat, sound, or electricity, maintaining temperature, soundproofing, or insulating electrical circuits. In construction, insulation materials are commonly used in walls, roofs, floors, and pipes to prevent heat loss, improve energy efficiency, and reduce heating and cooling costs. Insulation materials can take various forms, including fiberglass, polyethylene foam, rock wool, foam plastics, and more, depending on specific applications and performance requirements.

Additionally, in the electrical and electronics fields, insulation materials are employed to wrap wires, cables, and electronic components, preventing current leakage, shorts, and protecting equipment from moisture or other external factors. This ensures the safe operation of circuits. Insulation plays a vital role in construction and engineering, as well as in electrical and electronic applications, providing isolation and protection for heat, sound, or electricity
