Storm doors are typically made from materials such as aluminum, steel, and fiberglass. Aluminum storm doors are lightweight, durable, and resistant to rust, making them a good choice for many climates. Steel storm doors offer added strength and security, though they may require periodic maintenance to prevent rust. Fiberglass storm doors are known for their durability and resistance to weather conditions, making them an excellent option for homes in extreme climates. The best material for your home depends on factors like local weather conditions, maintenance preferences, and budget.
