Interior doors are classified into two types: pre-hung and slab. A pre-hung door, which consists of a frame-mounted door and hinges, is ready for installation and usage with a prepared entryway. A slab door is a simple door that does not include a frame, hinges, or handle set. It is usually made of wood and installed by driving nails or screws into the wall surface behind the door. Slab doors can be bought at home improvement stores in various sizes and styles. They are easy to install and cost less than pre-hung doors.
The most common types of interior doors are internal doors and exterior doors. Internal doors are used within a room of the house; they are typically made of wood and have glass or wooden panels. Exterior doors are used to enter a hall way or leave a house and are usually made of metal or wood. They may also have glass or wooden panels.
There are also double doors and folding doors. Double doors are identical on both sides and are used where you want to divide an area of space (such as a hallway) into two smaller areas. Folding doors are identical on one side only and fold back when not in use. They are useful for creating a private area such as a bedroom or bathroom or for simply dividing an area of space.
Finally, there are a number of other types of doors including patio doors, screen doors, and barn doors.
A slab door is a rectangular wood, fiberglass, or steel slab. It is the door without the frame, hinges, or hardware. A pre-hung door includes everything needed for installation and configuration. It's a door slab that has its own frame and hinges. You can buy pre-made frames for slab doors and they usually come with one or more slabs. The type of door you get depends on your needs and your budget.
Slab doors are used for interior doors that don't need to be kept open often or have heavy use because they're made from thick material. They are also good for rooms where soundproofing is important such as recording studios or music practice spaces. Slab doors tend to look most impressive when painted or stained dark colors. They also work well in modern and contemporary homes as opposed to traditional styles which prefer framed doors.
Pre-hung doors are used for exterior doors that will be opened and closed frequently. They include glass for transparancy and security. Pre-hung doors are also good for high traffic areas such as entrance ways or staircases. They require less maintenance than slab doors and can be bought already assembled.
Pre-hung doors can be any size but standard sizes range from 36 inches to 42 inches wide and 72 inches to 76 inches tall. Smaller sizes are useful for decorating small spaces while larger ones can fit through large openings like doorsways or windows.
A slab door is a simple, unadorned door that lacks a frame. It is the obligation of the do-it-yourselfers or installers to attach the slab door to an existing door frame or to build a new door frame. The word "slab" comes from the fact that these doors are made out of flat pieces of wood or metal that are glued together.
There are two types of slab doors: full and partial. Full slab doors are whole units that include the lintel over the opening. Partial slab doors only cover the actual door frame and leave the lintel over the opening exposed. Because full slab doors cannot be divided into sections, they are more difficult to install and take up more space when closed than partial doors. However, they are more secure because there is no way for anyone to see what's on the other side of the door if they try to break in.
Partial slab doors can be divided into three main categories: flush-mounted, embedded-mounted, and framed-out. In all cases, the lintel over the opening is left exposed. Flush-mounted partial slabs look like ordinary doors but instead of having a frame around them, they have a channel where a piece of molding can be fitted. These can be installed with the molding attached to the wall or detached and placed on a shelf or bracket.
