Magnetic Storm Windows: Pros and Cons

Historic homes are both a privilege and a pleasure to own and inhabit. Homeowners take great pride in preserving these magnificent landmarks, caring for their structures and aesthetics in ways that respect the buildings’ storied histories.

Historic homeowners have options when updating their building: restore to a specific era, rehabilitate and update as needed, or preserve as is. However, when maintaining an old home for habitability, homeowners often prefer to keep the home’s character in mind, including its original single-pane windows.

Whether interior or exterior, storm windows are popular additions because they keep the home’s overall aesthetic and original windows intact while improving energy efficiency and blocking outside noise. Magnetic storm windows are among the several styles to explore when deciding what storm windows will work best for your home.

What Are Magnetic Storm Windows?

Magnetic storm windows are a type of storm window with a metal frame installed around the window stop, after which the magnetic storm window is placed on the metal frame and held there by a strong magnetic field, creating a heavy-duty seal. This specific type of storm window has its own set of positives and negatives to consider.

Pros of Magnetic Storm Windows

  • Affordable price. Magnetic storm windows are one of the least expensive options available compared to other types of storm windows or replacing windows entirely.
  • Lightweight. It is easy to move and handle magnetic storm windows since they are durable but not heavy, making them accessible and manageable for anyone.
  • Ease of placement and removal. Interior magnetic storm windows are easy to place and takedown without the need for tools, thanks to their magnetic seal design. Removable magnetic window insulation is an excellent choice if you still want to be able to open your windows occasionally in the winter.
  • Removes condensation. Accumulating ice and condensation on windows is a common problem during the winter. The strong seal of magnetic storm windows all but eliminates this issue.
  • Noise reduction. Magnetic acrylic soundproof storm windows can block out up to 70% of outside noise when applied to a single-pane original window and up to 50% with a double-pane window (compared to replacement windows, which only reduce outside noise by approximately 25% and cost more). They are an excellent option for homes in busy neighborhoods or near busy roads. They also reduce sound exiting the house, enhancing privacy.
  • Energy-efficient. The strong seal of interior magnetic storm windows increases the original window’s performance, acting as a barrier to cold drafts and helping the home retain heat in the winter. Additionally, interior magnetic storm windows are often treated with an acrylic coating, which protects the home against ultra-violet ray damage.
  • Cost Saving. In addition to being less expensive to purchase and install than replacement windows, magnetic storm windows often quickly pay for themselves through lower energy bills.

Cons of Magnetic Storm Windows

  • Seal deterioration. Although it will take several years, the magnetic seal can weaken with time, reducing the window’s efficiency.
  • Aesthetic issues. Even applied on the interior, magnetic storm windows affect the home’s aesthetic. The metal bracket that holds magnetic windows in place is permanently attached to the window frame, remaining visible even when the magnetic windows are not in use. This is an especially problematic issue for homeowners who want to maintain the historic nature of their home.
  • Single-direction seal. Magnets attract in one direction; therefore, magnetic windows only protect against airflow one way rather than fully from every direction around the window frame.
  • Changing temperatures can cause failure. Most magnetic window inserts use acrylic that expands and contracts based on the temperature, while the metal bracket frame does not. The magnetic seal can break, and the whole panel can pop off the bracket when the window insert and magnets expand or contract.
  • Lengthy installation process and possible damage. Magnetic storm windows often require a cumbersome installation that includes permanent adhesive, drilling, and extra hardware that needs to be measured and assembled upon arrival, not ahead of time. It can take several hours and alter the quality of your home. Due to the lengthy and complicated installation process, it is also challenging to uninstall entirely and may leave permanent damage to your window frames.
  • Permanently damages window frame. Magnetic storm windows require permanent attachment of metal tracking to your window frame. When the panel is removed, the tracking remains. Even when if you remove the tracking, the adhesive and holes drilled into your window frame are difficult to remove and repair. This is a huge issue for historic, old-growth wood window frames, which are irreplaceable.

An Alternative to Magnetic Storm Windows

Another option to consider when searching for the right storm windows for your home is compression seal inserts.

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.

Built from silicone tubing that provides a seal from all directions, Indow compression seal inserts are stronger than magnetic storm windows. The inserts are resistant to changing temperatures that can cause failure in track-based systems. They absorb the expansion and contraction that comes with temperature shifts and provide excellent resistance to unwanted drafts and noise.

Every Indow compression seal insert is custom made to each window’s specifications. This makes them particularly well suited for historic homes where each window will have a slightly different size due to the homes settling over the years.

WE just took delivery of the two window inserts we ordered. they both fit perfectly. The most difficult part of the process was me trying to hold the laser measuring device still while taking the diaginal measurment! The Indow team was helpful and the ordering process was catch free. the finished product is just as they described. once installed, you can not even tell that they are there. I will warn you, if you have larger sizes they will come in a pretty large packing crate/box to protect them so be prepared. The only reason for 4 stars insted of 5 is they have just been istalled and we shall see how effective they are at reducing cold air, but they fit so snug that I anticipate they will be very effective. Just in time too, because our area is in a low temp/low wind chill pattern at the moment.

Window inserts help with sound since I live facing the street and the highway

This is a 5 star company from beginning to end. I purchased the I inserts in 2017 because the bedroom on the second story faced the street. These are very effective for street noise. Noticed a problem on one of the windows recently and they quickly took care of it due to their warranty. Customer service personnel are very helpful. The price of the windows was acceptable for top quality of sleep and less noise during the day

Recently purchased the acoustic window inserts for a couple of old windows facing a busy street and they've made a huge difference in terms of noise reduction! The measuring process was relatively easy with the laser measuring tool that Indow sent and the windows were delivered faster than expected. Martin was easy to work with and we would highly recommend Indow to those looking for window inserts.

Installed noise canceling acrylic Indow window inserts to deal with the road noise at my condo, 4 lane state road is 40 feet from the condo. Expensive custom fit, but oh my gosh, they cut the noise by 75%! Decibel meter app I trust shows a 6 Decibel noise reduction, average Db over 30 minutes. Turns out 6 Db is letting only 25% of noise through! I am one happy camper…

The Indow team was great from start to finish! They were very clear about each step. After installing the inserts my home has been significantly while still preserving the fabulous city views. For anyone who lives in a noisy street or city like NYC I would highly recommend it. Leave the chaos outside and come home to piece and quiet.

From start to finish, we were very pleased with our rep, Reed, and the other staff at the PDX will call! The inserts themselves are stupendous! We purchased six total for the noisiest, road side(s) of our home. The outcome was beyond our expectations! Not only did the three rooms that bordered the road become at least 70% quieter, the other end of our home did as well! I cannot recommend Indow inserts more! The technology makes sense to add the inserts rather than purchasing new windows. Great results and thank you! Paul and Paula Spilsbury

We are thrilled with our Indow window inserts! I'd been on the lookout for a more permanent solution to leaky windows in our third floor living space. I discovered Indow on social media but since then have learned of friends who'd had Indow recommended to them by their rennovation contractor. The entire process went smoothly with friendly reps at hand to talk through questions during measuring, etc. They fit perfectly and help us to maintain the beautiful design of the windows on our 100 year old home! Highly recommend!!

For townhouse living, this solved my problem with noise from my neighbor's with my kitchen window. A considerable decrease of noise indeed! Measurements were a bit frustrating so I recommend using a laser measurement device and following directions to use a string for the diagonal. They look great and were easy to push into place. I highly recommend as an alternative to buying a new window.
