What Are Storm Doors? [A Detailed Guide]

A storm door is a second outer door commonly installed for safety against storms.

It also allows for ventilation in fair weather. Storm doors feature two kinds of panels, including interchangeable glass panels and screen panels. Storm doors are available in many materials and sizes.

Let us discuss storm doors properties in detail.

Storm Door

A storm door is an outside door placed in front of the main door or back door primarily for the protection against extreme weather, particularly in the winter.

It also allows additional ventilation when the hotter weather comes. You can find variety of storm doors with glass fronts that screen panels.  You can replace them when required. It all depends on the design you select.

In some cases, the glass panel is removed, and therefore the screen is put in when warmer weather comes, then the glass panel is replaced in the fall in preparation for winter. Here’s, how to install storm doors!

Storm Doors Provide Security

One of the most common ways burglars force an entry into a house is through the front door. Burglars can break one door more quickly than two of them. For this reason, installing a storm door protects against break-ins.

 However, if you like a storm door that gives optimum security, consider these features:

  • The frame of the door is formed out of steel that’s a minimum of 16-gauge
  • The hinges of the door are tamper-resistant
  • The door is formed with heavy-duty tempered laminated glass
  • The door contains a double lock so that it uses a key in and out of doors

Doors Increase Energy Efficiency

One of the best features about storm doors is their design, as they are made to increase energy efficiency automatically.

Most storm doors contain three layers. These layers include a front and back layer alongside a layer of insulation in the middle.

When you install a door, you can get the potential to extend your home’s energy efficiency by up to 45 percent. Storm doors keep cold air outside in the winter, which helps to scale back your heating bill.

In the summertime, a door keeps the warmth out, suggesting you can use less air conditioning. Storm doors are tightly fitted inside the door frame, which protects from air leaking inside.

Do I need A Storm Door?

What are storm doors

Consider your climate when deciding whether or not a storm door is a sensible option for your home. If your door is exposed to the weather, a screen door is a good option.

You can avoid the option of having a storm door if you’ve got a replacement, well-sealed, energy-efficient front entrance.

Warmer climates don’t need storm doors to protect the door against winter weather, but the screen door would allow air to circulate during nice weather.

According to the Department of Energy, if your outside door receives a few hours of direct sun every day, you can skip the storm door.

The glass will absorb heat against the entry door and will damage it. Additionally, if your door is on a porch or under an overhang where it’s shielded from the weather, you don’t need a storm door.

Purpose of a Storm Door

A storm door serves several purposes. It allows additional light and increased ventilation into your home while still shielding from bugs.

When the weather is good, it allows you to open your entry door.

If you have a solid outside door and need the choice to observe kids play outside or let light into the house, a storm door allows that flexibility. When properly installed, the storm door can also protect your main entry door from rain, ice, and snow.

Another purpose is to feature extra insulation against air leaks. Storm doors can make a pocket of insulation that keeps cold air out and warm air in.


Do not underestimate a storm door. A storm door lives up to its name and provides an additional layer of protection for your home. It protects your main entry door from the weather — acting as a barrier against damage from wind, rain, and snow.

Moreover, it’s the finishing piece to your home’s exterior — giving it a personality and style charm. An elegant feature that enhances your property value. If you’re planning for home improvement, primarily your home exterior, getting a storm door installed should be a priority on your list.
