What Is A Window Head Jamb?
What Is A Window Head Jamb?
Window head jamb, is the vertical component at the very top of the window frame. The window sash is pressed up against it. As a result, the head has to be strong enough to bear the force of the sash. It must also have a certain level of rigidity, as it is the point at which the window is locked.
The width of the head jamb should be just slightly less than the width of the sash to ensure that it can bear pressure and stay in place. If you install a window with an undersized head jamb, you will end up with sagging sashes and possibly loose fasteners that will need to be replaced.
Access panels are used to cover any wiring or plumbing which may have been previously installed within your walls or roofing. Although they serve multiple purposes, one main reason for using them is to protect these systems from exposure from rain, snow and sun.
Heads are usually made of pine or poplar lumber; however, vinyl windows sometimes come with a synthetic material called plastic laminate. Plastic laminate is easier to install than wood but it is not as durable and it is not as attractive as wood.
If you are replacing an existing window head with a new one, you should measure it before purchasing a new one. You can place some low-tack masking tape on the inside of your window and mark off the measurements directly on your existing head jamb. If the existing head is not the correct size, you may want to make the necessary adjustments to fit a new one.
Be sure that your roof truss or rafter line up with the bottom corner of your window so that you don’t cut any sheet metal into your window frame. There should be no gaps so that any ice, rain or snow that may buildup will be pushed against the wall.
The best way to install a new head and sash on wood windows is to use high-quality caulking. The caulking will eliminate all kinds of gaps between the different pieces of wood and keep them together tightly so they won’t move in any direction during an earthquake or windstorm.
How Are Window Jamb Extensions Measured?
To find these measurements quickly, use a layout square to bridge between adjacent wall surfaces and then measure to the square’s edge. At this time, I also measure and record the inside dimensions of the window, including width and height.
Now, with the measurements record, you can easily order the correct window jambs to fit your needs. Before installing your window jamb extensions, make sure to install the existing window first. This way you will know how many extensions you need to install on the outermost corners of your home.
It is recommended that you mount or bracket every piece of wood so each extension is held firmly in place before installing any panels. The window face jamb is the horizontal between the sash and its backing. It is usually sized to fit the width of the window, but it can be trimmed down slightly to allow for increased visibility of the area.
To help keep your wall tidy, use a level while marking off every corner of your windows (including top and bottom) as well as 45-degree angles at each corner. With your measurements recorded, you can easily order new jamb extensions from your local home improvement store or online.
Window jamb extensions are such an important part of any window installation that it is essential you choose the right one for the job. If you purchase windows from different places; make sure to choose these extensions from a company that makes sure all their work meets with your satisfaction.
If you can’t do this, it will be very frustrating and costly for you to have to replace them later on when something goes wrong with your window installation. Be sure to clean off any dust or dirt from all parts before installing your window extension in its correct place on the window opening.
