Energy efficiency and insulation are critical factors in the design and operation of aircraft hangars. High-quality hangar doors play a pivotal role in maintaining optimal indoor climates, reducing energy consumption, and ensuring the protection of valuable assets. Understanding the Impact of Hangar Doors on Energy Efficiency Hangar doors are among the largest openings in a building, making them significant points for potential energy loss. Properly designed and insulated doors help regulate indoor temperatures by minimizing heat transfer, thereby reducing the load on heating and cooling systems. This regulation not only enhances comfort but also leads to substantial cost savings.
