energy efficient sliding glass doors

Sliding glass doors open up a home to more light, bigger views, fresh air, and easy access to the outdoors. The biggest sliding glass door systems can literally replace a wall with expansive glass panels, creating a spacious, airy connection between inside and outside.

With all that glass, what’s the impact on your home’s utilities? Are sliding glass doors energy efficient? We’re happy to report that the answer is yes. Getting the right sliding glass door system won’t harm your home’s energy efficiency — and may even improve it, which can translate into cost savings over the life of the system.

Here are five ways that that well-made, energy efficient sliding patio doors can actually save you money by keeping your utility bills in check.

The abundant natural light can reduce or eliminate the need for daytime electric lighting.

Depending on how large your energy efficient sliding glass doors are, they could be allowing plenty of natural daylight to flow in. Get enough light and you may not need to switch on any interior lamps or lighting elements. Lighting costs can be a big portion of home electricity use, so there are easy potential savings here.

Energy efficient glass keeps outdoor conditions from changing indoor temperatures.

Low-emissivity (or Low-E) glass is coated and constructed in such a way that it keeps a home cooler in the summer by reflecting the sun’s energy away from the home. It keeps that same home warmer in the winter by reflecting the home’s warmth back inside. This widely available energy efficient technology can help you save on heating and cooling bills during months with the most extreme temperatures.

Opening your sliding glass doors strategically can reduce the need for air conditioning.

Say you arrive home one afternoon to a stuffy house. It’s hotter inside than outside, where a nice breeze is blowing. With sliding doors — they don’t have to be energy efficient sliding doors for this to work — you can pull them open slightly to get air moving and reduce the stuffiness in the house. Or you can open them fully to invite that fantastic breeze inside and let it cool down your home.

For a great example of how this can be used strategically throughout a home, check out our San Francisco Residence project. This three-story Victorian includes a LaCantina door system on all three levels. The upper-floor system is kept open slightly throughout the day to help hot air escape, while the lower-floor systems are opened wide in lieu of air conditioning.

(Wondering how to keep bugs from flying in through your wide-open sliding doors? We offer screen options with each of our door systems. The screen is mounted inside, so you can open the door system and then pull the screen shut.)

The best energy efficient sliding patio doors help maintain a home’s building envelope, keeping indoor temperatures and humidity levels where you want them.

Not every door system is right for every geographical area, so taking the time to find the ones best suited for your location will ensure a more comfortable experience and potentially save you money in terms of reliable performance and steadier utility bills.

For example, if you live in an area with weather that allows wide-open doors much of the time but also has times of extreme temperatures, an energy efficient sliding door system such as LaCantina’s Contemporary Clad will expertly handle both situations and offer a level of thermal performance that meets even stringent building codes.

What if you live in an area with harsh weather that drums up strong winds, high humidity, and/or big swings in extreme temperatures? LaCantina’s Aluminum Thermally Controlled sliding glass door system (link to ) features thicker, 2-1/4" panels that can stand up to a high wind environment. That’s on top of its other great features, including energy efficient glass, thermal struts that keep humidity and outside temperatures at bay, and a self-draining weather-resistant sill with interior stop height options for all weather conditions.

Bottom line: If your sliding glass door system can withstand the tough temperatures and harsh conditions of extreme climates, you don’t have to worry about your heating and cooling bills getting out of control, no matter where you live.
