Improved insulation in farm buildings reduces energy consumption by minimizing the rate of heat transfer through the building envelope. By utilizing materials that trap air in small units—such as mineral wool, fiberglass, or plastic foams—insulation effectively slows the movement of heat into or out of a structure.1

This thermal resistance is critical for maintaining controlled internal environments, as it reduces the workload on heating and cooling systems. When a building is well-insulated, it requires less energy to counteract heat loss in winter or heat gain in summer, making it a highly cost-effective method for improving energy efficiency. Since the 1970s, building codes have increasingly mandated minimum insulation requirements to ensure these energy savings are realized across various types of structures.1
