An interior garage door fire rated is a specially designed door installed between a garage and the main living area to enhance fire safety. Built with fire-resistant materials, it helps prevent the spread of fire and smoke from the garage into the home for a specific time period, typically 20 to 90 minutes. These doors are often required by building codes and provide critical protection, giving residents more time to evacuate during emergencies. Ideal for homes with attached garages, they combine safety, durability, and peace of mind.
