Windows have been around for centuries, and they are one of the most important parts of any building. Not only do they let in light, but they also help regulate temperature and improve the aesthetics of a room. Windows come in all shapes, sizes, and materials, but all windows consist of several common parts that can be broken down into three basic categories: frame, sash, and hardware.


The frame is the perimeter of the window that holds it together and provides support to keep it securely in place. It typically consists of two vertical jambs on either side connected by a head at the top. Depending on the type of window, the frame may be made from vinyl, wood, metal or even fiberglass.


This is the movable part of the window which holds one or more lights (panes) of glass. It is mounted within the frame by pulleys or hinges and moves up and down or side to side depending on its design. Sashes often have locks to secure them shut when not in use.


This includes all components necessary to operate the window such as handles, locks, latches, pulleys and hinges. Most modern windows have handles that are easy to grip when opening or closing as well as locks for added security against intruders. Latches keep sashes closed tight while pulleys allow them to move freely up and down or sideways along their tracks. Hinges attach sashes to frames so that they can open outward for easy cleaning from outside your home.

Glazing Beads

Glazing beads are thin strips that attach to one side of each light (pane) inside a sash to hold it firmly in place within its frame. They come in different sizes depending on their application and may be made from plastic, aluminum or wood depending upon their purpose within an existing window design..

Glass Panels

A single pane window has just one sheet of glass while double-pane windows feature two sheets with a layer of air between them providing superior insulation properties against heat loss/gain through air leakage or conduction (the transfer of thermal energy). Triple-glazed windows use three layers with an insulating gas between them creating an even stronger barrier against extreme temperatures outside your home.

Weather Stripping

Weather stripping helps seal gaps between sashes and frames keeping airflow out while retaining valuable interior air quality inside your home thus reducing energy costs associated with controlling interior temperatures year round regardless if it’s the coldest winter day or hottest summer afternoon! Additionally, weather stripping works to reduce sound transmission from outdoors so you can enjoy your living space in peace and quiet when needed most!
