Hollow-Core Doors vs. Solid-Core Interior Doors

Solid-core and hollow-core interior doors differ in quality and characteristics. You may want to explore the differences before making a purchase. Solid-core doors are made of a filled-wood-fiber interior, and the exterior is plywood or a molded composite. They can also have a steel interior but a typical bedroom door will be constructed from wood particle fibers. These particular doors look very similar to a solid-core door made of solid wood.

One benefit of these doors is the good insulating factor they offer. The insulation also provides a fine sound barrier effect. Solid core doors can be either painted or stained and are offered in a variety of styles. Some are already primed; it would depend on the manufacturer and point of purchase. This type of door is considered to be both attractive and durable. They can add value to the total price of a home.

Although these doors offer eye appeal they do have some drawbacks. They expand and contract with the different temperatures and moisture levels. They are also heavy, usually weighing between 100-120 pounds apiece.

Hollow-core interior doors have a wood frame around the edges and the surface is either plywood or hardboard. The inside of the door usually has strategically placed rigid cardboard to help the door retain shape. These doors come in smooth or wood grained and take paint well. You can also buy them with a coat of primer and in different styles with panels offered as an option.

Hollow core doors won't warp because of heat and humidity changes in a home. They are also a good deal lighter, something to keep in mind if you are carrying them all up flights of stairs.

They also are not as durable or fire resistant as solid core doors. They are more difficult to repair due the very nature of being hollow.

After weighing in on your options, price may be the final deciding factor for interior doors. You can expect to pay top dollar for solid wood core doors. Hollow core doors are significantly more economical, approximately half the price.
