Patio doors are intended to be the gateways to fun and relaxation, providing access to your yard or an outdoor living area. If they’ve seen better days, however, and no longer operate as intended, they can be an annoyance at best and a hazard at worst. Replacing your old patio doors will not only improve your home’s functionality, but also its energy efficiency, security, and beauty. But unlike front entry doors, which are always hinged, patio doors come in several varieties, including sliding, garden, and folding. Which kind is right for your home will depend on several factors.

Terminology

Since patio door types are referred to in many different ways, any discussion must begin with a quick review of terminology. Hinged patio doors are called a few different names depending on their style. Those with large, undivided glass panes are usually called garden doors, and like all hinged doors, they can swing inward or outward. French doors have panes divided by grids, giving them a more traditional look.

Sliding doors, also called gliding doors, are divided into several types. The most common are traditional sliding doors with one large glass pane per panel. French sliding doors have panes with grids. Telescopic sliding doors have three or more doors that run on parallel tracks, allowing them all to be retracted against the wall.

Folding doors are also called accordion doors. They fold against one another, and like telescopic doors, can be retracted to a wall. Bi-folds have two panels, tri-folds three, etc.

Cost

Pricing for doors will vary depending on material, glass, and hardware choices, but in general, hinged French doors are between 10% and 20% more expensive than basic sliding doors. They also require more expertise to install since they must be properly hung and balanced. The cost for folding doors is comparable to sliding doors, but larger doors with more panels will cost more.

Energy  Efficiency

All types of patio doors are available with features such as tinting, insulation-filled frames, and double-panes for enhanced thermal performance. Because of their configuration, sliding doors are less prone to air infiltration than hinged French doors, making them more energy-efficient, but it’s unlikely you’ll notice any significant difference in your monthly utility bill between the two options.

Transition Type

When selecting a patio door, it’s important to consider what it’s providing access to. If your lawn comes right up to your house, a sliding door or French doors that open inward will be the better option, since it won’t sweep out over the grass. If you have a tiled patio, outward opening French doors are also an option. If your patio doors open to a fully enclosed space such as a screened-in porch or sunroom, folding doors offer the opportunity to open up the entire wall, creating a nearly seamless transition from the rest of your house into your outdoor living area.

Security

Sliding, hinged, and folding doors are all available with impact-resistant glass as well as multi-point, tamper-resistant locking systems. The weakest point with French doors is where they meet. Sliding patio doors avoid this potential vulnerability, but anti-lift devices such as lockable inside drop bolts can be unsightly.

Space Considerations

One of the biggest pluses with sliding doors is that they require very little space to operate. This is an important for cramped quarters. French doors require room to sweep in or out. Folding doors require enough space along the wall to allow the panels to stack against one another. One consideration often overlooked is raised thresholds, which are also called rebates. French and sliding doors have them. Folding doors have no-threshold options that eliminate a possible tripping hazard, but they are not as energy efficient as those with thresholds. For this reason, they’re recommended for interior use such as a house-to-sunroom transition.

Views

When it comes to unobstructed views, folding and telescoping doors are the way to go. These doors allow you to open up the entire wall for maximum exposure. The flip side of this coin is that when folding doors are closed, there’s more framing than with sliding doors, so they allow in less light. Because of their grids, traditional French doors have the most restrictive views, but “restrictive” is a relative term considering the amount of glass all patio doors feature.

Exterior doors lead a double life. When they’re open, they provide access to your home or backyard. When they’re closed, they provide a formidable barrier against would-be intruders and the elements. If you’re in the market for a new door, it’s fairly easy to see if it meets your standards for security. The locking hardware is right there for you to inspect. But how do you know if the door you’re considering is up to snuff when it comes to its thermal performance? It’s not quite so obvious. If you’re wondering what makes a door energy efficient, here are a few things to keep in mind before you purchase a new one.

Frame Material

When it comes to door frame materials, you want to choose something that is a poor conductor of heat. Fiberglass front doors and vinyl patio doors are two of the best options in terms of energy efficiency. Both of these materials resist thermal conduction quite effectively. Since steel is good at transferring heat, this frame material is a notch below the others. But most modern steel doors have insulation-filled inner chambers to boost their energy efficiency. Wood doors are the least energy efficient.

Style

Doors come in a variety of styles, from sleek and minimalistic to elaborate and eye-catching, but the single biggest determining factor for energy efficiency is the amount of glass that’s featured in its design. Doors with larger window panels tend to be less energy efficient than windowless doors, especially if the glass is a single pane (see below). With their large windows, patio doors are less energy efficient than entry doors, but modern designs incorporate several features to minimize heat transfer, including insulation filled frames. Hinged patio doors are less energy efficient than sliding models.

Glass Type

Just like windows, the glass in exterior doors is available in standard and high-performance packages. To maximize thermal performance, the glass must have two or three panes. The most energy efficient door glass also has argon or krypton gas between the panes to further reduce heat flow. Premium patio doors are available with these options as well, but to make them as energy efficient as possible, window treatments such as curtains or blinds are a must. They may block your view, but they’ll also block solar heat, which will keep your home cooler during warmer months.

Internal Insulation

The core of a door is either solid or a honeycomb of inner chambers. While solid-core doors are touted for their security, they are not as energy efficient as doors with insulation filled core. Polyurethane foam is most often used to create a thermal barrier that prevents heat transfer. Obviously, the more insulation the better the performance, which is another reason why doors with a small amount of glass or no glass at all are more energy efficient. Insulation-filled cores are smaller in window-dominated models. And as mentioned above, patio door frames can also be augmented with insulation.

Installation

The most energy-efficient doors will not provide the thermal performance they’re rated for if they’re not properly installed. Even doors that open easily and seem plumb, level, and square can be misaligned just enough to create gaps for air to get through. It may seem counter-intuitive, but improper installation is more common on pre-hung doors, which are packaged with their frames. That’s because the frames must be properly sealed and caulked to prevent airflow, and if this isn’t done with precision, it could allow air and moisture to seep into your home. Another common problem is weatherstripping that’s damaged during installation.
