Windows are made up of several components, each of which plays a crucial role in their function and performance. Here is a guide to the different parts of a window:

Frame: The frame is the outermost part of the window and supports the entire structure. It can be made of various materials, such as wood, vinyl, aluminum, or fiberglass.

Sash: The sash is the moveable part of the window that holds the glass. It can slide up and down, swing in and out, or tilt and turn depending on the type of window.

Glass: The glass is the most important part of the window as it allows light to enter and provides a view to the outside. It can be made of single or double-pane glass and can have various coatings and tints to enhance energy efficiency and privacy.

Glazing: The glazing is the process of securing the glass in the sash or frame with various materials such as putty, clips, or gaskets.

Pane: The pane is the individual sheet of glass that makes up the window. Double-pane windows have two panes of glass with a space in between to enhance energy efficiency.

Spacer: The spacer is the material that separates the two panes of glass in double-pane windows. It can be made of metal or plastic and is filled with insulating gas to enhance energy efficiency.

Weatherstripping: The weatherstripping is the material used to seal gaps between the sash and frame, preventing air infiltration and improving energy efficiency.

Hardware: The hardware refers to the various components used to open, close, and lock the window, such as handles, latches, hinges, and locks.

Understanding the different parts of a window can help you make informed decisions when choosing replacement windows or evaluating the performance of your existing windows.
