The thickness of the door can also depend on the style and design you prefer. Some traditional designs may call for thicker doors, while modern styles might use slightly thinner ones. However, it’s crucial to follow local building codes and regulations which may specify a minimum thickness for exterior doors to ensure security and energy efficiency.

  • Weather Resistance: Solid wood doors can be susceptible to warping, cracking, or rotting if they are exposed to extreme weather conditions without proper protection. It’s essential to use high-quality, weather-resistant wood species, apply a suitable finish, and maintain the door regularly.
  • Insulation: Solid wood doors can provide good insulation, but their insulating properties might not be as efficient as insulated steel or fiberglass doors. You can improve insulation by using thicker doors or adding weatherstripping.
  • Maintenance: Exterior solid wood doors require regular maintenance, including refinishing or resealing every few years to protect against moisture and UV damage.

How are wooden exterior doors made?

The door slab can be constructed of wood, fiberglass, or steel. Both fiberglass and steel doors consist of two skins stamped with a design and are then filled with an insulating material. Wood doors use stile and rail construction by joining multiple components to create an overall design.

Here is a simplified overview of the process:

  • Material Selection: High-quality wood species such as oak, mahogany, or fir are chosen for their durability and aesthetics.
  • Cutting and Shaping: The selected wood is cut and shaped into the desired door size and style. This can involve cutting the wood into stiles (vertical pieces) and rails (horizontal pieces) and joining them together with mortise and tenon joints.
  • Paneling: Some doors feature raised or recessed panels.
  • Assembly: The stiles, rails, and panels are assembled, glued, and clamped together. This forms the basic structure of the door.
  • Finishing: The door is sanded to a smooth surface, and a finish is applied. This finish can be paint, stain, varnish, or another protective coating. It enhances the door’s appearance and provides protection against the elements.
  • Hardware Installation: Hinges, locks, handles, and other hardware are installed according to the door’s design and function.
  • Quality Control: The finished door undergoes a quality control inspection to ensure it meets standards for size, shape, and finish.
