A pediment is an adorning gable used atop doors and windows on the front elevation of a building.
Pediments are often referred to as headers due to their nature of "topping" windows and doorways.
These architectural elements are intended to appear as an extension of the portal frame and produce a look of elegance.
Styles.
Pediments can be constructed in a classical triangular shape, as seen in Greek or Roman cultures, or in a more modern semi-circle or rectangular shape, and made from materials like wood, vinyl, cellular PVC and foam.
Pediments can be plain or have elaborate details like paneled, fluted, dentil or sunburst, and can be combined to increase your options.
Keystones can add another dimension to your crossheads and are sometimes used to hide seams if your headers were made using multiple pieces.
Try incorporating existing architecture elements with your headers to create a uniform look for your house.
Also, take into consideration the decorative gables of your house and whether they are using vents, moldings, gingerbread, brackets or corbels in the building design.
Door Pediments.
Door pediments are a great way to alter the look of the main entrance of your home.
The front door is the entry way where all of your guests arrive and a bold look can help set the tone for what is waiting on the inside.
Door surrounds that complement the use and appearance of door pediments are pilasters, pilaster capitals, ornamental friezes, door sidelight windows, door transom windows and mounting blocks for things like exterior lighting fixtures.
Other fixtures or objects that could be designed to maintain a parallel look are columns and freestanding planters located near your doors.
Window Pediments.
Installing window pediments is an easy way to give your house a makeover and give personality to your exterior.
By topping all the windows on the face of your house, you can create a look of architectural continuity.
It is generally acceptable for the pediment breastboard, or crosshatch, to be the same length or slightly wider than the window opening.
Combine with other balancing window accents like window trim, shutters and window boxes to give your windows a complete look.
They can also be used to fill empty space on a homes wall when detail, color, or accents are needed.
Adorning pediments above your windows and doors is an elegant way to transform the façade of your home.
The architectural detail added, by using pediments, is the perfect finishing touch to increase the value of your home and boost your aesthetic curb appeal.
