The doors on the exterior of your home differ greatly in material type from your interior doors, but interior doors themselves can also be different depending on the type and purpose of the room. Interior door materials are typically chosen based on how the room will be used, and whether additional soundproofing is required to keep noise either in or out. For example, your bathroom and bedroom doors might need different materials than those used for closets or other areas/rooms of your home. So what are these materials, and when are they used?

The Different Interior Door Materials

Solid Wood

Using solid wood doors can be more expensive than other options, but typically provides a more traditional and luxurious look. Douglas Fir, for example, is a popular softwood that may be used in more upscale settings. Pine is a less expensive option, so it may be more common generally. Solid wood can be a good choice for interior door materials, however, it is prone to shrinking and warping with changes in humidity and may not be an ideal choice in areas where there is significant moisture, such as a bathroom.


Manufactured using recycled wood fibers, MDF is an extremely common, widely available, and relatively affordable option for interior door materials compared to solid wood. These doors won’t warp like solid wood and will not have a wood grain-style finish. They are also very easy to paint and maintain.


Glass interior doors are becoming a more popular choice for many homes, specifically when homeowners are seeking a more detailed and decorative look. Glass panel inserts can be frosted to provide privacy, or transparent when used to separate common areas.

Solid Core

If you’re trying to keep costs lower, using a solid core door in place of a solid wood door is a good option. The exterior surface will be either plywood or molded composite, with an interior core that consists of a wood fiber strong enough to resemble solid wood.

Hollow Core

Hollow core interior doors are precisely what they sound like – they offer an exterior panel made from plywood or molded composite with a hollow interior. While there are numerous uses for hollow core doors inside of your home, they don’t offer noise suppression the way that a solid door can. They’re also much lighter and therefore aren’t as durable as solid wood.Choosing Interior Door Materials
