Insulated walls are designed to reduce heat transfer between the inside and outside of a building. They typically consist of materials like fiberglass, foam, or cellulose that trap air, providing a barrier against temperature changes. This helps maintain a comfortable indoor environment and can lead to energy savings. In addition to temperature control, insulated walls also help reduce noise from outside. This is particularly beneficial in urban areas or near busy roads. By minimizing sound transmission, insulated walls contribute to a quieter and more peaceful living or working space.
