The materials used inside the door compose its core. The type of core used affects the weight of the door, its ability to withstand impact, fire rating and sound transmission. The decision between solid core and hollow core needs to be made based on a cost vs benefit analysis. While hollow core doors are lighter and less expensive, solid core doors look and feel better, are more durable, and are much better at insulating sounds. If immediate cost and location are the only determining factors for purchasing an interior door then a hollow core might be the better choice. However, solid-core doors have much longer life spans. The cost of replacing hollow-core doors when they break will inevitably cost more money in the long run.
Should I buy a solid core or a hollow core door? Which is right for me? Many people are faced with these exact questions.

Hollow Core — Lighter in weight and more affordable than solid core doors. Hollow core doors are a good choice for areas where sound transmission is less important, like a closet or pantry.
Hollow core doors are lighter. This is because the interior core of the door is hollow, sometimes made of a honeycomb material. Being that they’re lighter they may be easier to handle and install.
A big advantage that hollow-core doors have is their immediate cost. Because these doors require less material and workmanship the cost of these doors will be less expensive than a solid-core door.
The major disadvantage is the durability of these doors. A major impact could easily puncture the veneer skin leaving a hole in the door.
Another disadvantage for this type of interior doors involves the finish. After painting these doors the veneers become wet and more flexible. Extra care is needed to support the door to prevent a bow or twist while the finish is drying.

Solid Core — Heavier and more resistant to normal wear. Solid core doors are commonly used in areas where more privacy is preferred. If interior noise reduction is a priority, consider a solid core door, which reduces sound transmission by up to 50 percent when compared to a hollow flush door.
The major advantage for these doors is their durability. These doors were built to last and will need less maintenance then its hollow core counterparts.
Another advantage is that these interior doors have noise cancelling abilities. Solid core doors are also more fire resistant than hollow core doors and could potentially isolate a fire.
Last but not least the quality of solid core doors is completely unmatched by hollow core doors.
The biggest disadvantage for a solid core door is that they are heavy and may cause damage to the frame if carelessly slammed closed. The door can pose a challenge to handle and transport all the way to your home.

Choosing the right door material for your project should be fairly clear now. Hollow core for lower traffic areas where they will receive less ware and solid core for privacy and higher finished quality areas.
