How to Make Your Sliding Doors More Energy Efficient

Posted on

Sliding glass doors are a beautiful addition to any home offering certain functional conveniences that allow you to walk in and out of the property by merely sliding the door aside and stepping through.

But one of the concerns that many homeowners have about sliding doors is their lack of energy-efficiency, as climate-controlled air is allowed to easily escape from inside the home. The result is higher heating and cooling bills and those costs can really add up over the course of the year.

If you suspect that your home is not as energy efficient as it could be you can take some steps to solve the problem by either implementing some small home improvements of your own or turning to replacement doors that have been manufactured for increased levels of energy-efficiency. We’re going to discuss all of these options and you can decide which is best for your home.

Simple and Affordable Options

Perhaps the doors in your home are older models that weren’t manufactured with energy saving patio door design. That’s okay. You can still take measures to weather-proof your doors and keep them from letting all of your energy seep out of the home.

Here are some of the steps you can take, each one is low-cost and relatively easy to carry out, you don’t even need to be highly adept with your home improvement skills either.

Weatherproofing Options

There are a couple of choices you have with respect to simple fixes that can be made on your doors to make them more energy efficient.


This is a pretty easy way to stop those pesky leaks. You have a choice of different types of strips, each one designed to close up the gaps that could develop between the sliding glass doors themselves, resulting in reduced energy-efficiency.

The construction of the strips incorporates brush filaments and Mylar to create a barrier of sorts to greatly reduce the amount of air that can escape from inside your home.

Compression Strips

These work in a much similar fashion as weather-stripping but the materials for their construction are different. It’s also because this type of weatherproofing option is designed to create a tighter seal along the edges of your sliding doors.

Compression stripping is typically manufactured with neoprene rubber and is easily customized to fit along the channel and sash of the door. They are resistant to all types of moisture, extreme temperatures, and chemicals. You just peel and expose the adhesive backing and apply it where you need to improve the energy-efficiency of your sliding doors.

Replacing Your Doors

So maybe the do-it-yourself options aren’t getting the job done, it might be time to just have those older, worn out doors replaced with newer, more energy-efficient models.

But there are a couple of things you’ll want to consider as you start to compare and contrast which types of doors fit best with your home.

Glass Options

The most prevalent component of your sliding glass door is the glass and you have a range of choices when you’re selecting replacement doors. Each one not only brings a certain aesthetic to the design of the door, but many of these glass choices have been treated with a low-emissivity coating that keeps energy in your home.

You can also find glass options that are fortified to raise the level of security provided by your sliding doors, this can also be useful in regions of the country where high winds and hurricane force gusts are common.

Material Options

The type of materials used in the manufacturing of your replacement doors can also play a role in their energy-efficiency. Certain materials are more popular than others with homeowners and all of them bring various benefits to your home.

Many consumers will choose fiberglass doors which provide reliable durability and resilience against a variety of environmental impacts like extreme temperatures and direct UV light from the sun. Vinyl is another option you might want to consider as it is easy to maintain and will continue to keep its appearance for years to come.

Energy Star Certification

As you shop around for the right sliding doors, you’ll want to choose Energy Star certified doors as these are the ideal option for making sure that your new purchase provides you with the most energy efficiency possible. This certification assures that your heating and cooling bills will remain low and your home’s energy won’t radiate to the world outside.
