Pre-hung modern interior doors are a great way to add depth and character to any room. They come in different styles, so you can find the ones that work best in your home. Before you go shopping for doors, though, you should understand the difference between interior and exterior doors. They’re not the same, and you don’t want to use an exterior door for rooms inside your house.


In this post, we’ll dive into how interior and exterior doors are different so you’ll be able to easily spot various kinds of doors when you’re shopping!

Different Materials and Strengths

Because exterior doors are designed to keep intruders out, they’re stronger than interior doors. Interior doors are only designed to add privacy and separate rooms from each other, so they don’t need to be as sturdy.


To provide safety and security, exterior doors are made from materials like steel, fiberglass, and wood. On the other hand, interior doors are often made from plywood or composites.

Various Styles

Interior door styles vary considerably depending on where they are located in a home. For example, a bedroom door could be a solid or paneled door. Doors connecting a living room and a dining room could be pocket doors or made of glass to provide a sense of openness between the two spaces. 


An exterior door to a garage will likely be metal due to fire safety regulations, whereas access to an outdoor patio could be through sliding glass doors or French doors. Front doors tend to be made of sturdy wood and sometimes have decorative features. 


The good news is that both exterior and interior doors can come in a variety of colors. Some people paint interior doors black to create the illusion of higher ceilings and may be curious if black interior doors are out of style. They’re not! In fact, they’re not just in style this year–they’re a timeless neutral.


Due to the variety of styles, there’s no one way to clean an exterior door. If you want to know how to clean interior doors, though, it’s easy. Simply dust them, spray them with a solution of water and dish soap, wipe away dirt and water with a cloth, and let them dry.

Where They Can Be Used

Although it probably doesn’t make economic sense, you can use an exterior door to add privacy and divide rooms in your home, but you can’t use an interior door as an entryway from outside. Interior doors aren’t strong enough to provide the safety and security you need from a front or back door.


While exterior doors are trickier to work with than interior doors, they can be used inside. Keep in mind, though, that exterior doors are usually wider, heavier, and more expensive than interior doors. Also, exterior doors always swing inward, something you’ll have to get used to if you’re using them for bedrooms.
