Technical diagram demonstrating the use of jamb extensions.

Jamb Extensions allow your window to fit the depth of your opening.

Jamb extensions are an interior window feature which allows your frame to fit window openings of varying depths. By extending the window jambs to the precise length required, your window is able to sit flush with your interior wall. So, if you have a window frame that isn’t quite as deep as your wall opening, jamb extensions can be used to make it fit. Once the appropriate jamb length is applied, your window is ready to finish with interior trim to match your décor. Our extensions can be factory applied in your choice of jamb widths and colours.
