Three sisters: single, double, and one-and-a-half doors.

Interior doors differ not only in the material from which they are made, but also in the number of canvases. Most often, single - floor and double-floor doors are installed in the premises, a little less often-one-and-a-half doors.

Single-panel doors, which are also called single-leaf doors. Their design follows from the name: single-leaf doors consist of one single door leaf-sash. Doors of this type are installed as entrance and interior doors. Most often, they are installed in a standard, small-sized opening. As a rule, the width of a single-leaf door is 85-95 cm, the height is 2 meters (if the doors are made according to the Western model, then 2 meters, 10 cm). However, today there is no need to adhere to strict standards, so if your doorway is wider, it is not difficult to install a door that is suitable for it.

Double doors (or double doors) consist of two door panels, which are made the same size. Doors consisting of two flaps are placed in a wide doorway. This is the main advantage of double-leaf doors - their high throughput. In addition, the doors are distinguished by a chic view, they can be beautifully opened in front of guests. High, double-leaf doors can make your home a real palace. 

One-and-a-half doors they are one-and-a-half doors and have no other name. 

The younger sister of double-and single-floor doors consists of one single sheet and one half sheet. In fact, one-and-a-half doors can be called a kind of double-leaf doors. They are also installed in a wide doorway, however, due to the fact that the second half is narrower than the other, they have a slightly lower capacity.
