Finding the right patio door isn’t just about aesthetics. It’s about performance, comfort, and reducing wasted energy. The best energy-efficient patio doors can help regulate indoor temperatures year-round, giving you better control over heating and cooling costs. At Davis Window and Door, we’ve seen firsthand how the right door system can transform a space, not just in how it looks, but how it performs.
From Metro Atlanta to Metro Charlotte, homeowners are becoming increasingly mindful of their homes’ efficiency. Patio doors, with their large glass surfaces and daily use, play a big role. That’s why we offer a carefully selected range of energy-efficient exterior doors that balance visual appeal with thermal performance.
In this guide, we’ll discuss the top-performing patio door types and features to look for, helping you make a choice that’s beautiful, functional, and smart.
Why Energy Efficiency Matters in Patio Doors
Patio doors are more than a design feature—they’re a vital part of your home’s envelope. Poorly insulated doors can become a major source of heat loss in the winter and heat gain during the summer, making HVAC systems work harder. This leads to higher energy bills and a less comfortable living environment.
An energy-efficient patio door keeps outdoor conditions from creeping inside. It keeps your home warmer in the cold months and cooler in the hot ones. Beyond comfort and cost savings, these doors also contribute to a greener, more sustainable home.

What Makes a Patio Door Energy Efficient?
There are a few key elements that make a patio door truly energy efficient. At Davis Window and Door, we help you understand how each feature contributes to long-term performance:
- Glazing Technology: Double or triple-pane glass filled with argon gas and coated with Low-E layers helps block thermal transfer.
- Frame Material: Vinyl, fiberglass, and composite frames offer superior insulation over traditional aluminum or wood.
- Weather Stripping: High-quality seals prevent drafts and reduce moisture penetration.
- U-Value: This measures how well a product insulates. The lower the U-value, the better the thermal performance.
- Solar Heat Gain Coefficient (SHGC): This rating tells you how much solar heat can pass through the glass. A lower SHGC is ideal in hot climates.
Marvin Elevate Sliding Patio Door
When it comes to high-performance and lasting beauty, the Marvin Elevate sliding patio door stands out. Built with a strong fiberglass exterior and warm wood interior, it balances strength and insulation. This hybrid frame resists warping, swelling, and temperature-related wear.
We’ve found that this door performs exceptionally well in both humid summers and cool winters across Georgia and the Carolinas. With multiple glazing options and ENERGY STAR® ratings, it’s a solid choice for homeowners who want comfort without sacrificing design.
Marvin Ultimate Inswing French Door
The Ultimate Inswing French Door is a traditional option with modern performance. Featuring multi-point locking systems and insulated glass options, it seals tightly while offering an elegant, classic look.
It works exceptionally well for homeowners who want a timeless architectural style without compromising on energy savings. At our showroom, we often demonstrate the difference between older French doors and this modern version, highlighting the added protection and insulation.
Marvin Modern Multi-Slide Door
Sleek, minimalist, and energy efficient—this is one of our favorites for contemporary homes. The Marvin Modern Multi-Slide Door can span wide openings with ease while maintaining a tight thermal seal. It’s engineered with a high-density fiberglass frame and dual thermal breaks to resist heat transfer.
If you want to blur the line between indoors and outdoors without creating drafts or hot spots, this door is for you. It also features continuous weather seals and triple-pane glass options, making it one of the best energy-efficient exterior doors available.
Fiberglass Patio Doors
Fiberglass is one of the most thermally stable materials. It expands and contracts far less than metal or vinyl, helping maintain a tight seal over time. That stability improves both energy performance and long-term durability.
At Davis Window and Door, we often recommend fiberglass patio doors for homeowners who want minimal maintenance with maximum efficiency. Many of these models come with Low-E coated glass and argon gas fills, keeping energy use in check throughout the year.
Vinyl Sliding Doors with Low-E Glass
Vinyl frames offer excellent natural insulation and are often the most budget-friendly option for improving energy efficiency. Vinyl sliding doors can dramatically improve your home’s thermal performance when paired with Low-E coated glass and argon gas.
We display several vinyl models in our Atlanta and Charlotte showrooms, making it easy for homeowners to compare finishes, configurations, and brands. These doors tend to offer the best value for energy-conscious upgrades without exceeding your budget.

Triple-Glazed Patio Doors
Triple-glazing is one of the most effective ways to boost your patio door’s insulation. Three panes of glass, separated by gas-filled chambers, reduce both heat transfer and outside noise.
We’ve seen triple-glazed options make a noticeable difference for homeowners in urban and rural environments, especially when placed in sun-drenched or north-facing areas. They may come at a slightly higher cost upfront, but they deliver significant savings over time.
Custom-Configured High-Performance Doors
Sometimes, off-the-shelf solutions don’t fit your space or your vision. That’s where our custom patio door configurations come in. We work closely with homeowners to design doors that meet both aesthetic goals and energy performance standards.
Everything can be tailored to fit your needs, from glass choices to frame colors to operational styles. And since all of our installation crews are certified by the manufacturers, we install each door with precision that lasts.
