Popular Interior Door Styles

Different interior doors have different properties in regards to customization, noise control, and durability with daily use. We carry the popular styles that many
homeowners, remodelers, and builders look for, including solid core, molded hollow core, and stile and rail doors.

WOOD

Generally solid wood interior doors are six panel pine, but interior wood doors can be constructed from softwoods and/or hardwoods, such as mahogany, cherry, alder, maple, oak and pine.

COMPOSITE WOOD

Composite wood doors are virtually identical to real wood doors, but are far stronger and more durable. One great advantage is affordability, as composite doors cost less than their solid wood counterparts.

HARDBOARD

Often the most affordable choice is a hardboard interior door. The hardboard is a fairly soft material, but is usually covered with a hard-baked paint. Hardboard doors can be molded with the look of natural wood grain.

MDF

Medium density fiberboard (MDF) is an engineered wood product made from recycled wood fiber and resin. MDF doors come in a variety of styles and are easier to paint than wood doors due to its smooth surface.
