What is "insulation"?
Insulation is the process of placing materials within walls, ceilings, and floors to reduce the transfer of heat, sound, or electricity. This act helps maintain comfortable indoor temperatures by preventing heat loss in winter and heat gain in summer, leading to energy efficiency in buildings. Insulation materials can include fiberglass, foam, cellulose, or reflective barriers, each chosen based on the specific needs of the structure. Proper insulation also contributes to noise reduction, making spaces quieter, and can help protect against moisture and condensation. Overall, insulation is essential for improving comfort and lowering energy costs in homes and buildings.
