Window Insert Replacements

When it comes to renovating a home to make it more energy-efficient, it can sometimes be hard to determine which projects will be most valuable.

Some projects, like replacing windows, may initially seem like an easy way to improve the energy performance of a home with some added benefits like soundproofing, but replacing windows can quickly become a costly investment that may not be worth the minimal return.

Fortunately, there may be more cost-effective alternatives, like window insert replacements, that provide the same benefits for a fraction of the time and money.

Full Window Replacement – Is It Worth It?

A full window replacement is when you remove an existing window down to the studs and a new window is installed in its place, including installing and painting a new frame and trim. By comparison, a window insert replacement is when you install a window pane into your existing window’s frame. This window insert fits tightly into your existing window frame without disturbing the original frame, exterior trim, or interior casing.

If the windows are not salvageable, it may be time to fully replace all the windows in a home. Most newer model windows have been developed to significantly reduce heat loss and improve a home’s energy efficiency. (However, if you have a historic home or need to preserve the original windows, it’s best to keep the original windows and find other ways to increase energy efficiency.)

In 2021, the cost to replace 10 existing 3×5-foot double-hung windows with insulated, low-E, simulated-divided-light vinyl windows with a custom-color exterior finish was $19,385.

In order to completely insulate the home, every single window needs to be replaced. This quickly becomes a very expensive commitment with money that would most likely have a bigger impact elsewhere. And, it’s unlikely the money spent would ever be recouped through energy savings — at least not for several decades, and most replacement window warranties do not last that long.

Replacing windows is not an amateur DIY project that can be easily done over a weekend. The only way to ensure the windows are installed properly and provide the best insulation possible is to hire a professional crew, which does not come cheap.

When renovating an older home to achieve a more contemporary design aesthetic, replacing outdated windows with a more modern style can update the look of both the interior and exterior of the home.

However, if the homeowner only wants to replace a few windows and is looking for replacements to match existing windows in the home, this may be more of a challenge. Models change with time and technology advances, so finding the very same window used before may not be possible.

Also, in some historic or custom homes, the windows may not be able to be changed at all. Windows specifically crafted for the home with stained glass simply cannot be replaced without risking the original integrity and charm of the space — or even be allowed if the home is designated as a historic property.

However, if the home is situated on a busy corner or next door to some particularly noisy neighbors, the noise dampening benefits of modern windows may seem appealing enough to rip out the old and invest heavily in the new.

However, it’s worth considering the alternatives before making such a costly decision.

What Are the Alternatives?

Advancements in technologies have drastically improved the performance of modern windows, but quality replacement window alternatives have also become readily available.

These alternatives are much more time and cost-effective than replacing old windows while still offering the same energy savings and noise dampening benefits.

Here are a few of the available replacement alternatives and why they may be the better option for any home.

Exterior Storm Windows

If the home is located in an area known for its adverse weather conditions and the existing windows could use an extra level of protection, exterior storm windows are a good option — especially on a tight budget.

Exterior storm windows are installed on the exterior of the house, outside of the preexisting windows. The primary function of storm windows is to provide extra wind and weather protection. They also provide an extra layer of insulation to normalize interior temperature, and they can help reduce noise.

They are much easier to install than replacement windows, as they simply screw into the exterior of the house and do not require an expert to install. And since they are installed on the outside of the home, exterior storm windows do not change the interior aesthetics — though they will change your exterior aesthetics.

However, exterior storm windows require a lot of maintenance and are difficult to clean thoroughly without unscrewing and can trap dirt and moisture against the interior window.

Poor quality exterior storm windows often lead to air leakage and little to no added insulation. So, if energy efficiency is important, this may not be the best option.

Also, while simple to install on a single-story home, reaching upper levels is difficult and could lead to an insufficient installation.

Window Inserts

Window inserts are fully functional secondary windows that work within the existing frames to seal drafts, reduce noise, and some even filter dangerous UV rays.

Replacement window inserts are easy to install and do not need extensive mounting hardware or professional help. Indow uses its patented silicone compression Tube to keep window inserts in place instead of hardware like tracking. This saves your window frames from damage, keeping them beautiful for years to come. The low-profile design means they virtually disappear once installed. If maintaining the integrity of a historic site is important, window inserts are the best option.

Window inserts regulate the temperature year-round for optimal energy savings, and they are easy to maintain since they do not need to be unscrewed to deep clean.

There are also different types of inserts that offer a variety of light-blocking capabilities. So, whether the goal is to block out UV rays, diffuse the light for a little privacy, or totally blackout a room for the optimal sleeping environment, there is a specific insert available.

And if noise cancellation is the most important factor, inserts can reduce unwanted noise by up to 70%* — incredible, right?

Interior Insulating Blinds

Interior insulating blinds are a type of window treatment designed to maximize energy efficiency. They are made of layers of pleated fabric materials that fold up accordion-style usually to the top of the window.

The pleated layers create a “honeycomb” effect that acts as a highly effective insulator to reduce heat loss in the winter and unwanted solar heat in the summer.

Interior insulating blinds come in a variety of colors, textures, and patterns to fit into any design aesthetic. Some even include automation and can be controlled by a remote or through a preplanned schedule.

These window treatments, however, work by covering the windows, which may not be the desirable outcome when dealing with historic or custom window features like stained glass. They also do not help air leakage from broken or drafty windows.

Working with Indow has been a great experience from start to finish. They answered all our questions & guided us through the whole process. We ordered 15 inserts & they have reduced the Highway noise that we were experiencing after buying our house. A great product & innovative company.

I live 20 feet from a busy road with lots of trucks. We almost didn't buy the house because of the noise. my house is the perfect candidate for indows. After installing them (myself. .. directions were so easy) we can barely hear any trucks noise at all. Indies live up to their claim and has made a huge difference.

I am very pleased with the noise reduction and heat-trapping effects of my Indow inserts. I bought three small inserts as an experiment for the noisiest part of the house all year round, and where it's cold in winter. They have done beautifully well in sealing out both noise and heat. My only issue has been to get one of them installed perfectly straightly on one side, but it was done in a difficult location and isn't that important. They are also quiet expensive, but I may get a federal tax rebate on them.

It could have been better if the pallet was collected after the delivery. Also the inserts are more beneficial for picture/fixed windows rather than open windows. The price of insert are expensive.

I was pleasantly surprised how well the appearance after installation, perfectly clear, plus reduce the noise from the outside more than I expected. I would definitely recommend anyone looking for noise reduction to consider these. I will be purchasing more as time goes on, thank you Indow

It has cut down noise tremendously and is definitely more efficient with keeping our cooling in and heat out this summer.

Indow is a trendsetter in eCommerce. They make the entire process of ordering, purchasing, and installing their product very easy for any walk of life; and, their communication processes are excellent. The inserts I purchased and installed were just as described. They are effectively blocking soundwaves, but not vibration, which was discussed during my initial call with an Indow Representative. I would recommend Indow window inserts to a friend.

Our window inserts have decreased road noise in our bedroom by 75 percent which we are very pleased with. The whole process was extremely simple and organized. Everyone we dealt with was professional and helpful. The inserts were simple to install and I would recommend to others.

They make it easy to measure and install and it does reduce the noise as I live next to a busy highway. I am happy with the purchase.

We have a multi-story building construction next block that starts at 7 a.m. daily and a busy street a few blocks away. Before the insert was in place in our bedroom, we heard every piece of construction equipment there, including the obnoxious beeps from vehicles backing down in the lot, and all of the emergency vehicles passing by on the avenue. Now, this sounds like something happening twenty blocks away, barely noticeable. This is a huge quality-of-life improvement from day one of the insert installation.

Effective and frequent communication from Indo Window starting with the order process, through production and post-delivery. The insert fit was excellent, fitting snuggly. The panel is quite effective in reducing noise. My wife was sleeping in the basement due to traffic noise. She is able to sleep in her bedroom again. Overall an excellent experience!
