Interior doors come in a variety of configurations to suit different needs and preferences. The most basic type of interior door is the single swinging door, while double doors are two doors often used for larger openings.
Doors can also come with sidelites or transoms, which are pieces of glass or narrow panels that run along the sides or above the door, allowing for additional light to enter a room.
Bifold doors can be set up or knocked down, and they fold in half to save space when opening. Bypass doors slide open on a track, allowing for full access to the contents and can come with standard or heavy-duty hardware.
One common type of interior door is the stile and rail door, which is constructed from stiles and rails with a panel in the middle. Another type is a molded door, which can have either a hollow core and solid core options. One popular style is the panel door, which can have either a flat or raised panel design. Another classic style is the French door, which features glass panels and can be found in various types such as clear, frit, bevel, or decorative glass.

Primed finger jointed jambs are a cost-effective option that can be painted to match the door or room. Veneered wood species or solid wood jambs can match the door’s grain, providing a seamless and cohesive look. The depth of the jamb can range from 3-7/8 inches to 14 inches with wider jambs adding stability.

A 4-sided jamb is a good option for units with attics as it provides a finished appearance on all sides.
Interior door casing is a trim that covers the gap between the door jamb and the wall, providing a finished appearance to the door opening. The joint between the casing and the jamb can be either a butt joint or a mitered joint, with a mitered joint providing a cleaner, more seamless appearance.

The handing of a door is determined by standing with your back facing the hinges.
If the door swings towards your left, it’s a left-handed door, if the door swings towards your right, it is a right-handed door.
Handed doors must also identify if the design should go to the hinge or stop side.
