Aluminum doors can have a lifespan of over 30 years. Of course, not all aluminum doors are manufactured the same. Since aluminum is a conductive material, the door frame needs to be thermally broken in order to be energy efficient and to perform under our Canadian conditions. Triple glazing, glass thickness, and the number of gaskets also play an important role in the door’s durability. Additionally, optional protective coatings, such as anodization, reduce exterior maintenance and prevent rust. Our entire product line offers thermally broken frames, triple glazing, and three gaskets for maximum quality and long-term performance.
