Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

It’s usually a good idea to use a metal primer before painting a metal garage door, and, even if you do, you’ll need a paint that’s specifically designed to coat metal for the best results. Metal primer helps create a good surface for the paint to stick to your metal garage door, and it will help prevent bubbling, chipping, and peeling after it dries. It’s a bit more expensive to prime your door before painting, but it’s usually worthwhile, as the paint will last longer.

While the benefits of garage door screens usually outweigh the downsides, there are some cons to installing one. First off, they can be quite expensive, especially if you’re having a professional install a retracting screen or a custom size screen. Second, they let fresh air and natural light in, but they also don’t provide the same privacy from people in the neighborhood that a solid door does. As you might guess, screens also won’t insulate your garage, so they’re often not usable in colder weather.

Plexiglass garage doors are a durable and less expensive alternative to garage doors, and they maintain a similar aesthetic. Other elegant types of garage doors include carriage house garage doors and stylish wooden garage doors, but these don’t offer the same look as glass, of course.
