Wood Windows For True Luxury

Marvin Ultimate windows are designed to be stronger, more durable, and longer-lasting than its competitors. While many companies use roll-form aluminum (aluminum no thicker than a soda can that wraps around the wood), Marvin Ultimate windows use extruded aluminum that exceeds the American Architectural Manufacturer’s Association’s toughest specification.

In short – it’s what you DON’T see in Marvin Ultimate windows that makes them so superior.

In addition, the interior wood of Marvin Ultimate windows can be ordered pre-finished in a variety of stains and finishes to match the inside of your home. This means you’ll have the exact look you want to match the luxury of your home, with the durability and strength required to withstand the moisture from the Potomac and temperature fluctuations in Bethesda.

Vinyl Alternative: Integrity by Marvin’s Ultrex Technology

When you want the look of wood without the maintenance or expense, Integrity by Marvin is the best choice for you. Ultrex, Integrity by Marvin’s exclusive technology, is eight times stronger than vinyl. This means you can have a larger, stronger window with more glass… withOUT worrying about how long your new window will last. (Ultrex windows have a 38% longer life expectancy than vinyl windows.)

Stronger materials bend and flex less, which means your window’s seals and operation will last longer… even in the dramatic temperature changes that seasons here in Bethesda bring.

The paintable finish of Integrity by Marvin windows is completely customizable to your home – and it resists cracking, scratching or fading, even with 48,000 hours of sun.
