In the world of design, black is gaining more popularity. More people are going for black interior and exterior windows and doors. They believe that black is bold, beautiful, and hot. Using black aluminum windows has an amazing way of displaying class and elegance in your building.

A measure of the thickness of the aluminum window frame determines the durability of any finish on it. The two types of thickness are the extruded form and the roll form. The extruded aluminum form is thicker and tends to retain its coating for a longer period. Also, it’s more resistant to harsh weather conditions and physical impacts from hits than the roll-form.


Some of the paint finish used on aluminum windows include urethane, polyester, Kynar, etc.  With some testing done by American Architectural Manufacturers Association (AAMA), it derived the rating for aluminum finishes.

After stacking, the door usually appears like a single-panel door when viewed from both outsides or inside the house.
