Interior Doors


Interior doors are manufactured with either hollow core or solid wood materials. The average mid-size home has about 24 interior doors. That’s 800 square feet of visual impact. This is arguably the largest design element in the home. See below to learn how you can use trends, style, and inspiration to create a look that defines your home.


Don’t confuse solid core doors with solid wood doors. Solid wood doors are made with lumber. Assembled in pieces, they provide the familiar stile-and-rail construction standardized in home construction for many years. Solid wood doors have an array of options and custom capabilities.


Solid core doors are similar in application to a wood interior door regarding the look and feel. Solid core doors are a popular choice for today’s home. Solid core doors have a wooden framework, with an engineered wood core, and a molded veneer providing you with personalization and performance.

Hollow core doors are not actually hollow. Hollow core doors have a wooden framework, typically 1 3/8 inches in thickness with a honeycomb or grid-like core consisting of cardboard, foam or a combination of both. The frame and core support a veneer face adhered to the surface on both sides. Because veneer won’t support hardware, solid wood blocking for doorknob installation is placed inside the frame.
