Purpose of lintel
Purpose of sill level
Lintel level and sill levels are parts of the wall.
Lintel Level
When a window or door is constructed, a load of bricks above it needs a base. And lintels are provided for the same. Above the window, a beam-like structure mostly made up of concrete (Structural wall) is constructed. the length of this beam can limit to slightly more than the length of the window or it can exceed to cover the whole wall and can act as a lintel beam. the height where the lintel beam is constructed is called lintel level
Sill level
The sill level are similar to the lintel level but it is constructed below the window and its length is the same as the length of the window only. the height at which this sill is constructed is called the sill level.
Sill is a horizontal bed of mortar usually as wide as the wall provided below windows or other openings. Sill supports the windows.
Lintel is a structural RCC beam spanning throughout the length of the building or above the openings alone. Lintel supports the wall above the openings.
Eg. The window starts from the sill below it and ends with the lintel above it. (Upwards)

Window sill level
The level which is exactly below the window frame it is a horizontal shelf at the bottom of the window frame. It protects the junction of the window and provides additional support and stability for the window. Having level around 0.6m to 0.9m from floor level. variety of window sill materials available.
Lintel level:
This is the just above the window and door frame to take load coming from wall which is above the window and door frame. It may be of concrete, wooden, R.C.C., stone, etc. The level of lintel is around 2.1m to 2.3m.
| SR.NO151. | PLINTH LEVEL | SILL LEVEL | LINTEL LEVEL |
|---|
| 1 | The plinth is the part of the superstructure between the top of the tie beam at the finished ground level | Sill level is the part of window . Window sill are provided between the bottom of window frame and wall below | Lintel beam the actual frame of door or window is not strong enough to support the weight of the wall above the opening and separate structural element has, therefore to be introduced. this known as lintel and similar to a beam |
| 2 | This level of below the floor fishing . This level constructed beam that beam called Tie beam. | This level between the base portion of the window and portion of the floor above ground level (upwards) is called the Sill level. A mortar bed or concrete bed is laid at the base of the window. | The level between the top portion of the window and the top slab is called the Lintel level. |
| 3 | The plinth is generally made up of Reinforced concrete or cement mortar. | The sill is generally made up of Reinforced concrete or cement mortar. | The lintel is generally made up of Reinforced concrete or cement mortar. |
Basically sill is known as the horizontal bed of the mortar which is usually as wide as the wall provided below windows or other openings. Therefore sill supports the windows.
And lintel is made up of reinforced concrete or cement mortar .Therefore lintel support the wall above the openings.
