    Grills & muntins

    A grill or muntin is a piece of wood or various other materials such as metal or vinyl that are inserted between panels or used to divide a window.

According to the style of the window, the customer’s requirements, and the type of glass, window companies offer a variety of standard and custom window options.


    Sashes are the movable parts of windows, which include windowpanes and the mechanical structure of a window. Sashes can be customized and crafted to meet your unique needs.

    Sash Locks

    Window jambs provide structural support for the window. Jambs are located on the sides of windows, while top jambs are located on the top. It is possible to open and close a window with tracks or rails placed inside jambs, depending on the type of window.


    On either side of the sash, there is a stile that serves as the main vertical section of the window. Stiles are present in all windows, and the length of a stile depends on the size of the window itself.


    Rails allow windows to open and close and are generally found on double hung windows. In most cases, a two-piece rail is used to open and close a window. It is the check rail that closes the window and locks it.


    Sills, also known as windowsills, are located at the bottom of window frames. Water and debris are directed downward by sills, away from buildings. A windowsill is an excellent place to place potted plants and décor that will survive direct sunlight.

    Window Styles

    The right window style design can be found regardless of whether you want a traditional look or a design that brings in airflow during the summer. We have compiled a directory of window styles that we have seen in the industry and that we love for any home.

    Single-hung windows

    A single-hung window has an operable bottom sash that tilts inward for easier cleaning as well as greater airflow.

    Double-hung windows

    A double-hung window has both a bottom and top operable sash, making it one of the most popular windows on the market today. Due to their open design, they allow controlled airflow and are often coupled with window screens, so they can be used regardless of the weather.

    Casement windows

    These windows are hinged on one side and open horizontally. They have become a mainstay in larger homes. In addition to being able to operate as stand-alone windows, the windows can also be used as a set of windows for larger spaces. Window seals and locking mechanisms are relatively easy to operate and the windows are quite energy efficient.

    Awning windows

    Due to their superior ventilation and smaller structure, awning replacement windows Pleasanton CA are often found in basements and upper floors. Both new builds and replacement windows use these windows since they can be opened in virtually any weather condition.

    Slider windows

    Most suburban homes use slider windows for bedrooms and bathrooms because of their low profile and ease of use. You can customize the sliding sashes, so they open to the left or to the right. Some homeowners have opted for double sliding windows that open from both sides, perfect for an entertaining area over a patio.

    Bay windows

    Adding a bay window to your home can increase its value and also increase its square footage. They are among the most beautiful windows you can buy.
