Roll Form vs Extruded Aluminum Windows - Marvin Windows & Doors Available at Kuiken Brothers in NJ & NY

Often, we are asked why Marvin Windows are more expensive and if they are worth the extra money. The answer is they are more expensive because they are designed and built better. There are many examples of this, but we think the picture below shows a clear difference. Marvin extruded aluminum on the left, roll-form aluminum on the right.

Roll Form vs Extruded Aluminum Windows - Kuiken Brothers Marvin Windows-001

If you are ready to make an investment in windows, consider the overall structure of the window – sometimes it is what you don’t see that really matters. Marvin’s extruded aluminum is substantially stronger than roll-form (coil) aluminum. Marvin’s cladding is so strong, it exceeds the American Architectural Manufacturers Association’s toughest specification (2605-05) for aluminum cladding. This specification requires both extruded aluminum and a 70% Kynar finish.

Here is another way to explain the difference between Marvin Windows extruded aluminum and other available finishes:


Marvin Clad (above) – Marvin’s extruded aluminum cladding offers strength and durability that roll-form and vinyl clad windows can’t offer. The difference in strength is similar to the difference in the thickness of an industrial chair versus an inexpensive lawn chair.


Roll-Form (above) – Roll-form aluminum isn’t much thicker than a soda can. It is easily bent and damaged. Most windows using roll-form aluminum come standard with a less expensive paint coating that can easily fade, chalk and scratch.


Vinyl (above) – Vinyl expands and contracts due to heat and cold. Couple this issue with the damaging effects of UV light, and the vinyl will eventually chalk and fade. The weather’s constant climatic attack breaks down vinyl, leaving a brittle, faded shell behind.
