What Does Jamb Liner Mean In Construction?
A Jamb liner is a small strip of wood applied to the edge of a window jamb to increase its width for use in thicker materials.
It spans the distance and covers the space between the window frame and finished interior wall, and can be installed at the factory or on-site. Universal fit, vinyl compression jamb liners fit most major brands, while tilt-takeout sashes can be assembled without tilting outwardly.
How To Measure Jamb Liners?
To measure jamb liners, start by measuring the width between the side jambs (wood surface to wood surface) in three places: top, middle, and bottom. Temporarily remove any jamb liners before taking measurements.
Make sure to measure directly from the head jamb, avoiding any stops, weatherstrip, and liners. At the sill, measure to the top of the sloped sill on the exterior side of the lower sash.
Next, measure the height at the left side, middle and right side. Ensure that a minimum 3 3/8″ wide jamb depth (“opening”) exists for replacement jamb liners.
Finally, note down all measurements on a worksheet for reference. It is important to remember that not all windows are exactly the same size and to measure accurately to the nearest 1/8″.
What Is A Concealed Jamb Liner?
A concealed jamb liner is a type of window frame that is covered with a matching interior wood species and finish. It is designed to provide a modern look with slimmer lines and more visible glass, while still maintaining a traditional style.
The concealed jamb liner overlays all mechanical balance systems, such as the tilt latch which allows the window to be opened and closed without having to remove the sash. It also provides improved DP ratings due to its structural changes.
The wood removable grilles feature a frame design that offers superior strength compared to stick grilles offered by other window manufacturers.

What Is A Jamb Size?
The standard size for a door jamb for interior doors is 4 ⅝-inches in-depth. This depth provides an extra ⅛-inch to accommodate walls that may be slightly thicker than the standard.
Other typical sizes for door jambs include 4 9/16-inches if you have a 2×4 frame and ½-inch drywall, 5 ½-inches if you have a 2×4 frame and thick drywall, and 6 9/16-inches if you have a 2×6 frame or a block wall.
The thickness of the door jamb is typically determined by the framing lumber in the wall. Standard interior door jamb thickness on prehung doors is 4 9/16 inches, while an alternate jamb thickness is 6 9/16 inches designed to fit 2×6 wood stud walls constructed by studs that are 1 ½ inches by 5½ inches with drywall and exterior sheathing.
What Is The Difference Between Sill And Jamb?
The difference between a sill and a jamb is that a jamb is the main vertical part forming the sides of a window frame, while a sill is the main horizontal part forming the bottom of the window frame.
The sill and jamb are two of the main components of a window frame, along with the head, which forms the top of the frame. Other parts of a window include rails, check rails, mullions, locks, hinges, and cladding.
