Before diving into these windows' drawbacks, let's first define what they are. Storm windows are a type of window installed on an existing window's exterior. Storm windows are designed to provide an extra layer of insulation and protection against the elements.

How Do Storm Windows Work?

They work by creating an air pocket between the existing window and the storm window. This air pocket acts as an insulator, reducing the amount of heat transfer between the inside and outside of your home. This can keep your home warmer in the winter and cooler in the summer, potentially reducing your energy bills.

The Drawbacks of Storm Windows

While this type of window may seem like a good idea on the surface, several drawbacks make it a less-than-ideal choice for homeowners. Let's take a closer look at these drawbacks.

Limited Energy Savings

One of the main reasons homeowners choose storm windows is for their energy-saving benefits. However, the reality is that the energy savings from storm windows are often minimal.

Reduced Natural Light

Another drawback of storm windows is that they can reduce the amount of natural light that enters your home. This is because the storm window is installed on the exterior of the existing window, creating an extra layer that blocks some of the natural light.

This can make your home feel darker and more closed off, which can be a major downside for homeowners who value natural light in their living spaces. These types of windows are generally found in older homes.

Difficult to Clean

Cleaning windows is already a chore, but it becomes even more complicated with storm windows. Because storm windows are installed on the exterior of the existing window, they can be difficult to access for cleaning. It can lead to dirty, streaky windows.

Limited Air Flow

Another major drawback of exterior storm windows is that they limit the amount of airflow in your home. This is because the storm window creates an extra layer that must be opened to open the existing window. This can be a major inconvenience, especially during the warmer months when you want to let fresh air into your home; these are found in older historic homes.

Potential for Moisture Buildup

One of the biggest concerns with storm windows is the potential for moisture buildup between the existing and storm windows. This can happen when there is a temperature difference between the inside and outside of your home, causing condensation to form on the inside of the storm window; when you see this happening, it's time to replace your windows.

This moisture buildup can lead to mold and mildew growth, which can harm your health and your home's health. It can also cause damage to your existing window, leading to costly repairs.

If you're looking to improve your home's energy efficiency, several alternatives to storm windows may be a better option for you. These include:

Double-paned Windows

Double-paned windows are a popular choice for homeowners looking to improve the energy efficiency of their homes. They consist of two panes of glass with a layer of gas in between, providing better insulation than storm windows.

Caulking and Weatherstripping

Caulking and weatherstripping are simple and affordable ways to improve your home's energy efficiency. These methods involve sealing gaps or cracks around your windows and doors to prevent air leakage. While they may not provide as much insulation as other options, they can still significantly affect your energy bills.

Conclusion

While storm windows may seem like a good idea, they have several drawbacks that make them a less-than-ideal choice for homeowners. From limited energy savings to reduced natural light and difficult cleaning, there are several reasons why storm windows are not a good option for your home. Instead, consider alternatives such as double-paned windows, window film, or caulking to improve your home's energy efficiency without the drawbacks of storm windows.
