The price and appearance are the first few things that most homeowners would look at when buying a door for their house. However, if you want to maintain the look and reduce the maintenance cost in the future, selecting between hollow or solid core doors is important.


Doors are essential investments to increase your house security and comfort. Purchasing a door because they look aesthetic or costs less is never a wise thing to do. It is better to check the door’s features and specifications that will match your preference. In this article, we will compare hollow and solid core doors so you can have a better idea of which type of door is best for your house.

What Is a Hollow Core Door?

Hollow core doors are made of flat fiberboard or laminated wood without a thick and solid core interior. Although hollow core doors are said to be hollow on the inside, they are not fully empty. To retain structural integrity, these doors contain a honeycomb cardboard interior that is wrapped in veneer or fiberboard. The majority of homes have hollow doors to save money on construction.

Advantages of Using a Hollow Core Door

  • Affordable
  • Lightweight
  • Easy to install
  • Less likely to warp

Disadvantages of Using a Hollow Core Door

  • Prone to damage. Although this phenomenon does not happen a lot, slamming a hollow core door into stops, hard kicking, or throwing objects with a significant amount of load might bring major structural damage into it.
  • Heat insulation. Because of its structure, hollow core doors can hold some heat, but the air spaces inside the door also allow greater heat to pass through.
  • Sound insulation. Hollow core doors are not good sound barriers. If you don’t want to hear loud noises from other rooms, this type of door is not suitable for you.

How To Reduce Noise on Hollow Core Doors?

If you already installed hollow core doors inside your house, you don’t need to replace them all at once just to improve some features. Here are the things you can do to increase the soundproofing capabilities of your door.

Weather Stripping

You can put weather strips around the door contour to close the air gaps. These strips are self-adhesive and thin so you can fit them on areas where the door meets the casing. Weather strips usually cost around $10.

Door Sweep

Most hollow core doors have big gaps on the upper and lower part. The gaps allow more air and noise to transfer between rooms. The door sweep costs around $20, and it can be a cheap solution to your noise problems.

What Is a Solid Core Door?

These doors contain synthetic wood and an engineered wooden core that is wrapped with a wood veneer and fine wood. Doors with solid interior structures are ideal to use for interior and exterior passageways and as an internal garage door. You can invest in a more secure solid core door, but keep in mind that you may be paying more for aesthetics than functionality.

Advantages of Using a Solid Core Door

To give you more ideas on why people chose doors with thicker interior structures, here are the pros of having one in your establishment:

  • Better protection and security. This type of door will not be easily damaged when subjected to a significant amount of force such as heavy kicking and throwing heavy materials on it. Solid core doors have higher fire resistance than hollow core doors.
  • Less locking problems. Warping and expanding wood cause a variety of door lock issues but this is not a common problem for solid core doors.
  • Better weather resistance capabilities than hollow core doors. Doors with a solid core offer good insulation properties. Also, the veneer covering the core gives great security.
  • Good sound barrier. The solid core scatters sound waves to lessen the noise transfer between rooms.

Disadvantages of Using a Solid Core Door

  • Heavy. Solid core doors are hard to install single-handedly. Likewise, it is hard to carry and transport to your home.
  • Prone to shrinkage. Changes in temperature and frequent exposure to moisture cause the wooden solid core door to contract and expand.
  • More expensive than hollow core doors.

Hollow Core vs Solid Core Doors

What Is the Difference Between Solid Core and Hollow Core Doors?

The amount of material used and the interior structure are the key differences between solid and hollow core doors. A veneer is attached to a hardwood frame in a hollow core door while in solid core doors, the interior component fills in the gaps with more wood, making it stronger, heavier, and has better noise reduction capabilities.

Privacy and Security

Both doors give enough privacy.  But with a stronger design and more thickness, a solid core door has better security and privacy than a hollow core door. If a door with a hollow core is kicked in, the door will likely fracture. In contrast, solid core doors can withstand a great amount of force.

Sound Insulation

Hollow core doors are not a great sound barrier, unlike those with a solid interior. Doors with denser inner components can muffle sound more effectively.

Durability and Maintenance

When a hollow core door is damaged, it is best to replace it right away because repairing it will cost you a lot of money anyway.  They are more prone to damage by severe humidity, thus they may have to be replaced more frequently. While doors with thick interior materials can last longer because of their durability and require less maintenance than hollow core doors.


Hollow core doors are cheaper than solid core ones. These doors typically cost around $75 while solid core doors usually cost $150 for a basic type.

Hollow Core vs Solid Core Doors: Which One Is Better?

Hollow core doors are economic options if you have a small budget for your house that requires three or more doors to be installed, and noise reduction is not a big deal for your family. However, for better functionality and durability, investing in solid core doors will increase your security and provide better noise reduction.

That concludes our comparison between hollow and solid core doors. Basically, solid core doors are better but they are more expensive than hollow core doors. Investing in these doors might initially cost more but you are less likely to face any problems in the future.
