Insulating Apartment Windows: Tips + Ideas for Renters

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.

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.

I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.

I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.

I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!

Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!

We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!

We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!

Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.

Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes

Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.

My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.

Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.

Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
