Garage door insulation also makes your garage door easier to maintain in the long run. Because insulated panels are thicker, they are less susceptible to dents or scratches from external forces such as wind. Insulated door panels are also better able to withstand weather conditions because their materials are not easily damaged by extreme heat or cold weather. Insulated garage doors also protect against moisture, pests, and other factors that can damage the door in the long term. This means you don’t have to replace or repair your insulated garage door as often as you would with a non-insulated garage door.
