Why Choose Marvin Aluminum Door & Windows

Extruded aluminum is thicker and more durable than roll form. Thinner aluminum, such as roll form, can dent more easily, and does not offer the structural performance of extruded aluminum.

Marvin extruded aluminum parts are formed first, then painted. This eliminates paint cracks and imperfections and allows for a smooth, uniform finish that evenly covers the curves and angles of the product. The 70% PVDF fluoropolymer acrylic enamel finish is smooth to the touch which distinguishes it from the rough, textured finish on competitive aluminum products.

The PVDF finish meets the highest American Architectural Manufacturers Association (AAMA) 2605 requirements. During the manufacturing process, the PVDF finish is chemically bonded to the aluminum. The PVDF finish is standard for all Ultimate and select Coastline finishes.

To provide uniform durability over time, Marvin Ultimate uses extruded aluminum on all major window components. Some manufacturers choose to cut costs by using lower-quality materials on certain parts. This can lead to quicker chalking and fading and inconsistent weatherability.

Because of its design flexibility, extruded aluminum can be shaped to closely match existing windows or doors in a way that can’t be done with other materials. Extruded aluminum is created by heating aluminum and pushing it through a die which creates a clean, and precise shape. The aluminum is then cut and fabricated into different shapes, sizes, and widths. Roll form aluminum comes on a large roll and is pressed down over a form to create the product components.
