Insulating your apartment windows can help make your space more energy-efficient, comfortable, and budget-friendly. But if you’re renting the apartment you’re currently in, you might not want to splurge on expensive solutions for a drafty space that isn’t your forever home. 

Thankfully, though, there are a few ways to keep your apartment more energy-efficient with affordable, easy-to-install options available. We’ll break down a few of our favorite ways to insulate apartment windows here. 

Why Bother with Insulation?

Whether you’ve just moved into a new apartment or lived in your home for a few years, it’s a good idea to inspect your windows on an annual basis to ensure that they’re providing your space with a well-ventilated and well-insulated environment. 

Windows play an important role in protecting the home’s building envelope. To keep the home well-sealed, windows and doors require regular maintenance to stay functional.

Any air leaks in your window design can result in higher utility bills during the winter or summer. They also make it harder to call your apartment your “home sweet home” when you’re never quite comfortable with the temperature. 

“If your existing windows are in good condition, taking steps to reduce the energy loss through windows can make your home more comfortable and save you money on energy bills,” according to Energy.gov

You can inspect the windows and doors to see if there are any leaks or gaps that need attention. “See if you can rattle them, since movement means possible air leaks. If you can see daylight around a door or window frame, then the door or window leaks. You can usually seal these leaks by caulking or weather-stripping them,” suggest experts at Energy.gov.

Options for Insulating Windows

There are a few products and methods that make it easy for anyone to insulate their windows for optimal functionality — even if you have a smaller budget. 

Rope Caulking

If you’re in a pinch, rope caulking is a rubber-based rope material that offers a cheap yet  effective solution for sealing bigger gaps in windows. There are a few brands of rope caulking out there to choose from. Simply follow the instructions on the product packaging for installation.  

Bubble Wrap Insulation

Bubble wrap offers another quick and budget-friendly solution for apartment-dwellers. While it might not be the most stylish strategy for insulation, placing the bubble side of the material against wet glass will add a layer of protection to the windows. “The still layer of air trapped in the bubbles gives a cheap double-glazed-type effect,” scientist Jenny Edwards told ABC Radio

Thermal Curtains

Thermal curtains feature a special lining that helps trap warm air inside the layers of fabric. They also offer a more aesthetically appealing solution to apartment dwellers. For optimal impact, any curtains you select will need to cover the length and width of the entire window. 

Window Inserts

Window inserts are an easy-to-install and more permanent solution for insulation, in which a panel is simply inserted on top of the original window. Window inserts can be a more expensive option than bubble wrap or caulking, but their custom sizes and durable features make them a viable long-term option for insulating apartment windows

“With any efficiency improvements, take steps to ensure proper installation and check for air leaks again after making the improvement,” suggests Energy.gov.
