Design Options

Infinity from Marvin offers a complete collection of
finishes and hardware to complement your vision.



We offer a variety of exterior colors to suit any home’s style. We use a proprietary acrylic finish on our Ultrex® fiberglass that’s virtually impermeable to help protect your investment from wind, weather and color fading.


* Finish samples are approximate. Please schedule an in-home consultation or visit a showroom to see actual color samples.



We use the same acrylic finish on our interior as on our exterior for superior performance. Or choose EverWood®, our stainable engineered wood grain finish, to blend seamlessly with your existing décor. All offer virtually no maintenance — just remarkably reliable performance.

Retractable screen

Infinity’s Bi-Fold Door uses a pleated fabric screen that slides open and can be positioned as desired. Bi-parting and uni-directional options are available depending on your configuration. The screen folds tightly to the jamb when not in use for an uninterrupted view outside.

Frequently Asked Questions

What is the standard size for a patio door?

Unlike windows, patio doors do have several standard sizes. The most common size for a 2 panel door is either 60”w x 80”h or 72”w x 80” h. However, Infinity Patio doors from Marvin come in an expanded level of standard sizes up to 96” high and 4 panel options up to 190” wide! Standard sizes or call number sizes are usually less cost than custom sizes which are available in ¼” increments.

Does my Patio Door get new Trim?

Yes, all of our Infinity Patio Doors and French doors from Marvin come with new interior trim and exterior capping. The reason for this, is all of our Patio Doors are done using New Construction Full Frame Installation Methods.

Can I add a Bigger Patio Door to the Existing Opening?

For the most part yes however there are many factors that play into the difficulty and cost. For instance, if you have a brick exterior versus a vinyl siding exterior, the brick will be exponentially more to enlarge and reframe. If we are changing the opening, sometimes we have to remove the entire interior and exterior wall to add a new header and new support beams which can cost as much as the door itself. Either way we are happy to provide a quote for any project involving this method.

What is the difference between a Sliding Patio Door and Sliding French Patio Door?

The only difference is the frame. The sliding patio door frame is more narrow and has more glass space versus the sliding patio door which has a frame that mimics that traditional look of a French door. So it has the ease of operation of a patio door with the style of a French door.

Can I get a Black Exterior and Black Exterior Fiberglass Patio Door?

Yes, Infinity from Marvin recently released their ALL Ebony Sliding Patio Door and Sliding French Door options for a truly modern and eye-catching installation.
