Interior Door Styles:

  • These are the classic doors. They are solid wood and made for both exterior and interior use. They are made from both hardwoods (like oak) and softwoods (like pine, which is very common). Softwood doors are most common due to their lighter weight and cost, but they are not quite as durable as their hardwood cousins.

  • HDF or MDF is harder and more resistant to denting than hardboard (but not stronger than solid wood). Available in an array of styles, they have a paneled, modern look that’s making HDF and MDF doors a growing, popular choice.

  • Glass doors are visually attractive and let more light into any home. They need to be built well (especially for exterior usage), but when applied to a home (whether interior or exterior), they add beauty and can make a statement.

  • It is very common, especially for new construction. These doors are 1-3/8” thick and made of wood stiles and rails. The interior generally consists of cardboard webbing, and the exterior is made of veneer. If taken care of, they can last for a long time. But rough use can lead to denting, and if hit hard, they can puncture.

Exterior Door Styles:

  • The classic door. Made for both exterior and interior purposes, these doors are made of solid wood, which offers strength and good insulating capabilities. Hardwoods such as oak are generally best for exterior doors (and are very dent-resistant). Softwoods like pine dent easier but are still fairly durable.

  • These doors are similar to a hollow-core interior door, but with a difference, you’ve probably figured out. Yes, the space within the wood frame is solid (filled with particleboard, for instance). They are heavy (what you want for an exterior door). But you’ll want to keep the veneer protected with paint to keep the particleboard from getting wet.

  • Gaining in popularity and becoming common for exterior door use, fiberglass doors offer appealing qualities. They can be molded into a variety of shapes and styles (come in a variety of colors and can be painted) are durable and more resistant to the elements (keep from warping, shrinking, expanding, etc.).

  • Yes, these are becoming common for homes (having been mostly used for commercial purposes). These can either have a steel exterior with a foam core or a foam core wrapped in steel with a wood veneer over it all. As you can guess, these are very strong and insulate very well.
