What is the difference between interior wood door and exterior wood door?

While interior doors wear out much less, exterior doors require an extra thick core, usually made of wood, to prevent heat and cold from entering. Exterior doors almost always include a thick layer of sheet metal to insulate and protect against weather damage. If we start with the basic use of doors, the exterior doors are designed to act as the main entrance of your building and are made to be able to withstand all the natural elements they face every day. Interior doors are in a much safer environment, so their construction can be quite basic and can be done at a fraction of the cost.

This is why exterior doors are made of solid wood and a solid core, while interior doors typically have a hollow core. This makes exterior doors much heavier, while interior doors are much lighter. Interior doors don't need to be as sturdy as exterior doors, as no one wants to open and close heavy doors all the time, so using solid wood is a waste in this case. The heavier nature of exterior doors means that they provide additional insulation and prevent drafts and cold from entering from outside.

Real or simulated raised panels are often found on interior and exterior doors as facial decorations. Interior doors are usually the same on both sides, while exterior doors have decorative panels on only one side. Exterior door glass is often frosted, while interior door glass is rare, with the exception of French-style doors. The first difference is that the exterior doors are heavy and the interior doors are light.

The interior doors are likely not soundproofed due to their hollow shape. Nobody likes to open or close heavy interior doors inside their house on a daily basis, so exterior doors are stronger and heavier. Exterior doors are designed to be heavy due to the additional insulation needed to prevent drafts and cold. The doors are designed according to the weather conditions they face.

When it comes to interior and exterior doors, exterior doors are often thicker than interior doors. Exterior doors are thicker to protect your home from outside elements, such as unwanted visitors and the weather, and thicker exterior doors provide better thermal and acoustic insulation than thinner interior doors.

Because of their higher insulation values, steel doors are generally more energy efficient than wooden doors, meaning that they keep the air conditioner inside the house and the outside air outside.

It's not uncommon for mid-range interior doors to have a wood fiber product at the core to make them appear solid and dampen sound. They tend to be more expensive than interior doors because the core is insulated, while interior doors are usually hollow, since they have no purpose or need for insulation. The locking plate must be attached to the door with screws at least 3 inches long that extend beyond the jamb, regardless of the material of the door. Solid interior doors can provide some insulation against drafts, but very few interior doors are insulated.

A solid wood door enhances the curb appeal of any home, regardless of whether it has one or two doors. The fact that interior doors are cheaper may make you use them as exterior doors, but doing so is not a good idea. Interior and exterior doors may look similar to that of exterior doors, but they may also differ in some ways. This is why a special and more resistant glue is used on exterior doors, while interior doors can be constructed with normal glues without any problem.

Every door is constructed differently, and exterior doors (wooden front doors) receive special treatment to withstand the elements and heavy use. Although steel doors are the most economical, their life expectancy is lower than that of a wooden or fiberglass door, especially in humid climates.
