The interior doors are any doors that does not provide access to the outside of a home or building, like a closet door, bedroom door, bathroom door, or office door. Standard interior doors are simply one-piece doors that fit an opening and are mounted on hinges to one side of the opening. They swing out or into a room, depending on installation, and can accommodate a doorknob, which can be locked from inside the room. Some of these doors are solid wood, but many are hollow. There are many different types of interior doors that you may choose to have in your home. With the wide variety of doors available it can be difficult to decide what type of doors will look best in your home. Whether you are building a new construction or working on a home improvement project, the right interior door can be a wonderful accent to a room.
The lowest grade of interior doors are made of thin wood with a hollow core. The term hollow core refers to the fact that the door has nothing in between the interior of the door and the exterior. This hollow area allows noises to travel freely from room to room. A higher grade of interior door that is still relatively inexpensive has a hollow core. The wood that the door is made from, however, is heavier. This helps to somewhat muffle the noise in between the rooms. These doors can be very attractive, and make a nice and affordable choice for many people.
