Insulation is a critical building material used to reduce heat transfer, enhance energy efficiency, and improve indoor comfort in residential, commercial, and industrial structures. It acts as a thermal barrier, helping to maintain consistent indoor temperatures by limiting the flow of heat in and out of a building. Common types of insulation include fiberglass batts, spray foam, rigid foam boards, mineral wool, and blown-in cellulose, each suited for different applications such as walls, attics, floors, and HVAC systems. In addition to thermal resistance (measured as R-value), many insulation materials also offer benefits like sound absorption, fire resistance, and moisture control. Properly installed insulation reduces heating and cooling costs, contributes to a building’s sustainability, and supports compliance with modern energy codes and green building standards. It plays a vital role in creating comfortable, energy-efficient, and environmentally responsible structures.
