What is a Jamb Window? (with photos)

Window frames are common to many window installations.

A window frame is part of a window’s structural support. The jambs are located inside the window frame, along the top and sides, and in the case of windows that open, the jambs can house rails or rails used to manipulate the window, along with devices such as latches that are used. to lock the window when it is closed. Similar structural supports around a door are also known as “jambs” and more generally, a “jamb” is any type of vertical support around an opening.

Jambs are located inside the window frame, along the top and sides.

Technically, window sills are known as side sills when they run along the sides of the window and as head jambs when they run along the top of the window. Jambs are not necessarily necessary, but they are common to many window installations. Numerous companies that produce windows also make casements and casement extensions that can be used to help adjust their products; the frame can be a weak point in a window if not installed correctly, allowing for leaks or safety issues.

The material used to make a window frame can vary and can be wood, plastic, vinyl or metal. Window frames can be painted to match a structure’s finish or left unfinished, depending on the material and aesthetics of the structure. In cases where windows begin to move erratically or gaps appear around the window, replacing the window frame can sometimes solve the problem, at less cost than replacing an entire window or re-framing the entire window.

A contractor can determine whether or not a window frame needs replacing and get the job done relatively quickly. People who are skilled with basic construction tasks can also work on their own window shutters, ranging from fitting new ones to allowing a new window to fit into an existing opening to replacing old shutters that are starting to warp, rot or leak so that an original window can be left in place. It is important to take some time when working with window frames, as a failure to fit them well and properly can result in problems ranging from a window that won’t open to a window that is so loose it’s easy to pop out of the frame. .

People inspecting structures they are considering purchasing should also examine window jambs. If the windows are leaking, the jambs will betray signs in the form of stains and rot. In addition to indicating that the jambs need replacing, rot and stains around the window sill can suggest that there may be other water damage that is not visible, such as rotting as a result of water seeping into the frame of the structure.
