In order to understand the benefits and drawbacks of a storm door, you need to know what it is, what it looks like, and the different types of storm doors available. We’ll also discuss how a storm door differs from a screen door. Then you can confidently decide whether a storm door is right for your home.

A storm door is an extra door installed in front of the main door. It’s made of glass and metal (typically aluminum or stainless steel) and can vary in design and appearance. There’s a small gap between the storm door and the main door so that the storm door doesn’t touch the front door.

The main purpose of a storm door is to protect the entry door from weather damage, including rain, snow, and wind. This protection extends the life span of the main door and prevents it from premature aging due to excess sun, extreme temperatures, and weather exposure.

Storm Door Glass

Most storm doors feature a large glass panel with a thin metal frame. Because the storm door is designed to protect the main door, the glass is typically made of tempered glass with a low e glass coating. Tempered glass is a type of safety glass, which means that it is safer than regular annealed glass.

Tempered glass is much stronger, more heat resistant, and breaks differently than annealed glass. It is four times stronger than regular glass, and has more impact resistance. This means it’s harder to break and is less likely to shatter from normal wear and tear. For this reason, it is the standard glass type for storm doors.

In addition to the tempered glass, most storm doors have a low e glass coating to prevent sunlight from heating the gap between the storm door and the main door. Low e glass, short for low emissivity glass, is a type of window glazing created to improve the door glass or window’s insulating performance.

A special coating is applied to the glass to minimize the amount of infrared and ultraviolet light that comes through without minimizing the amount of natural light coming into the space. This coating is microscopically thin and isn’t visible to the naked eye. As a transparent coating, it reflects heat away from the glass. This specialized storm door glass coating is the top choice for energy efficiency and keeping the internal house temperature steady.

Types of Storm Doors

Storm doors can vary in appearance and material. In general, there are three types of storm doors: full-view, mid-view, and high-view. Full-view storm doors have a full glass panel. Some have two separated glass panels divided by a metal rail. Others have a large, single glass panel that fills the entire door.

Full-view storm doors have a ventilation option in the form of a retractable screen or an interchangeable full screen. The retractable screen is found on storm doors that have two glass panels: the top glass panel slides down to bring the retractable screen down. Storm doors with an interchangeable full screen usually have a full glass panel that has to be removed and replaced with a screen.

Mid-view storm doors are three-quarters glass with a metal panel at the bottom of the door. These storm doors can also have retractable or interchangeable screens.

Finally, there are high-view storm doors that are half glass on the top and half metal on the bottom. These are the doors that typically display beautiful metalwork, and can come in a variety of styles. They also have ventilation options, depending on the design.

Pros and Cons of Storm Doors

Now that you know what a storm door is and the different options available, it’s time to dive into why a storm door could benefit your home. We’ll also cover the reasons why someone wouldn’t want a storm door. That way, you can evaluate the pros and cons and decide if getting a storm door is the right choice for you.

Storm Door Pros

Extra Protection

The main purpose of a storm door—and its biggest benefit—is added protection for your entry door. A storm door prevents moisture, harsh weather, and wind from directly hitting your main door. Whether your door is metal or wood, this added protection will increase your entry door’s lifespan.

By contrast, a wooden or metal door exposed to the elements will eventually wear down and show signs of age. This is especially true for doors without an awning or porch. If you have a high-quality exterior door exposed to the elements, you’ll want to preserve its appearance and structural integrity. A storm door is a great solution.

Besides protecting the front door, a storm door also protects the inside of your home from insects and rodents. A storm door lets you open your entry door to welcome fresh air and natural light without letting in unwanted critters.

While the front door has been mentioned frequently, storm doors are an easy way to add protection to any of your exterior doors, including back doors, patio doors, and garage doors. A custom storm door can even include a pet door, letting your pet come and go without leaving the main door open.

Improved Insulation

Along with an extra layer of protection, a storm door improves the overall energy efficiency of the home. If the glass in a storm door is double or triple-paned and has a low e glass coating, it will provide an insulated layer for your entry door.

The low e glass coating will reflect heat away from the glass, helping it stabilize internal temperatures. During the summer, it will reflect hot air away from the door, keeping the inside cool. During winter, it will reflect the warm air inside back into the house.

Along with the insulated glass, the air gap between the main door and the storm door also acts as an insulated layer. This air gap will reduce heat transfer as long as both the storm door and entry door are insulated.

Another way a storm door improves the insulation and energy efficiency of a home is by preventing drafts. A fully sealed storm door prevents drafts from reaching the entry door. And if the entry door is also fully sealed with weatherstripping, the chances of air leakage is significantly reduced. Your home will remain draft-free, even when strong gusts of wind are hitting your door.

These factors can lower your energy bills. With a high-quality storm door, solid wood doors, and double-paned windows, your home's energy efficiency increases significantly.

This means your heating and cooling system won’t have to kick on as frequently because the internal temperatures are stabilized. Not only will this help you save on energy bills each month, but it will also increase the lifespan of your HVAC system.

Ventilation and Light

One significant benefit of a storm door is that it allows you to open your entry doors on warm days to let fresh air and light flow into the space. The storm door remains closed to protect your home from unwanted pests, making it a great fit for homes that need more light and ventilation.

Most storm door styles offer ventilation options, like a retractable or interchangeable screen. Plus, the screened portion of a storm door is typically large, allowing plenty of fresh air flow into the space.

While there are many front doors with glass windows, not many of them are full glass like storm doors. This means they don’t let in as much natural light as a storm door does. So, when the front door is opened, a storm door will let in abundant natural light. This is especially nice for dark foyers and entryways.

One added benefit of storm doors is that when the main door is opened, they give you a clear view of the outside. This is helpful for those who wish to keep an eye on kids or pets while they’re outside.

Security

A high-quality storm door adds an extra layer of security to your home. Some storm doors are designed with their own locking mechanism, such as a lever lock and deadbolt. With a locking storm door, your home is that much harder to break into.

Most thieves target homes that are easy to enter. The more difficult you make it to break in, the less likely someone will try. With a locking storm door, you’re alerting any would-be thieves that your home is not an easy target. In this way, storm doors not only protect your home from the elements, but also from intruders.

While a storm door is not considered a security door, they do offer another level of security by simply making your home harder to break into. This is important to consider if you live in a city or high-traffic area. Plus, high-view storm doors with metal frameworks are even more imposing and harder to break into since they’re not full glass.

If security is a concern, be sure to look for storm door styles that can lock. Not all storm doors on the market have a locking mechanism in place, so be sure to look for ones that do before you buy.

Storm Door Cons

We’ve covered the reasons why a storm door will benefit your home, so now let’s talk about the drawbacks of having a storm door.

Hides Decorative Front Doors

If you have a beautiful, luxury front door, why would you want to hide it? A common concern with storm doors is that they can hide or detract from the beauty of the entry door. This is especially true for homes with a high quality solid wood or metal front door.

Let’s say you just spent time, money, and energy on designing a front door replacement. You’ve finally found the perfect front door, and you’re thrilled with the results. Unfortunately, with a storm door, all of that work and money is partially hidden from view. Is this something you’re okay with?

Stylish front doors add to the overall aesthetic of the home. They also boost curb appeal, increase home value, and impress your guests—benefits that matter to many homeowners. However, a storm door might impact these perks and alter the home’s aesthetic.

If you’re in love with how your front door looks, you may not want to cover it with a storm door. Of course, modern storm doors can be designed to be sleek and stylish, but they’ll still take away from your colorful or decorative front door.
