Patio Door Buying Guide

Whether you’re tired of looking at your aging sliding glass door or planning a major remodel with a new patio door in mind, it’s important to research what types of patio doors are available as well as the varying styles. Check out the different considerations to think about with patio doors, like the material, style, energy efficiency, and options that can make a difference.

Consider space 

If you’re thinking about a patio door replacement project, get started by scheduling a free, no-pressure consultation with a Marvin® Replacement design consultant. They’ll measure the space for your home’s exact specifications and talk you through all your options. When you move forward with Marvin Replacement for your project, a project manager will set a measure appointment to confirm the specifications before your order is sent to our manufacturing facility.  

Patio door material 

The material used to make a patio door can make a difference in the look, cost, and energy efficiency for your home. Common materials include: wood, vinyl, fiberglass, and aluminum.  

Wood 

Wood patio doors look great but may require more maintenance than other patio doors.  

Vinyl 

Vinyl patio doors remain a popular choice for homeowners because they don't require much maintenance, come in a variety of colors, and offer an attractive price point.

Fiberglass 

Fiberglass patio doors combine strength, style, and durability—without the maintenance of wood. Marvin Replacement’s proprietary Ultrex® fiberglass is 8x stronger than vinyl and has lower thermal conductivity than aluminum, so homes retain more heat in winter and stay cooler in the summer.  

Patio door types 

Sliding glass door 

Sliding glass doors are among the most popular patio door types because they can let in more natural light than one-panel doors and won't interfere with furniture. Marvin Replacement’s Sliding Patio Door is customizable in 2, 3, or 4 panel configurations for up to a 16-foot wide view.  

Sliding French door 

A sliding French door offers the same great functionality as a Sliding Patio Door, but features the wider profile of a traditional French door. Marvin Replacement’s Sliding French Door comes in the same configuration options as the Sliding Patio Door.  

Inswing French patio door 

Inswing French doors add design appeal to a home and work well if outdoor space is tight. Marvin Replacement’s Inswing French patio doors come in 1, 2, or 3 panel configurations.  

Bi-Fold patio door 

Bi-fold or folding patio doors can provide expansive views and natural light while creating inviting indoor-outdoor living. Marvin Replacement Bi-fold doors are available with up to seven panels, spanning up to 22-feet wide. The panels stack to allow more airflow with a uni-directional configuration while a bi-fold door will open from the center for a symmetrical look when open.  

Energy efficiency 

Ratings make a difference with patio doors. Look for the U-factor, Visible Transmittance, Solar Heat Gain Coefficient and Air Leakage. 

U-factor measures heat loss to the outside. The lower the number, the less heat that escapes. 

Visible Transmittance measures how much natural light, minus the heat, comes into a home. The higher the VT number, the more light that enters, which can reduce the need for artificial light and possibly reduce utility costs. 

Solar Heat Gain Coefficient measures heat gain from the sun entering your home. A lower SHGC can reduce cooling costs. A high SHGC can reduce heating costs.  

Air Leakage measures how much air will enter a room and is typically ≤0.3. 

Glass 

Glass can have different coatings to adapt to different climates. Marvin Replacement has four glass coating options: Low E1, Low E2, Low E3, and Low E3/ERS.
