Windows are doors that have glass installations in the openings to let light and air in and let people see outside. For ventilation, there often have openings. They consist of a frame that slides into the wall opening and shutters made of glass or wood in connection to the frame with hinges.

Functional Requirements of a window
- A window’s primary function is to allow for daylight and a view.
Besides, other performance requirements include:
- Providing ventilation – providing adequate controlled air exchange while minimizing infiltration and exfiltration brought on by uncontrolled air exchange requires careful design.
- A barrier to the flow of heat – can help a home’s insulation and temperature control, giving its occupants a more comfortable indoor climate.
- Blocking the transmission of sound – additionally, increase outside noise insulation to give residents more peace.
- Outside views – give property owners the chance to portray their home’s charm and beauty.
- Privacy – enhancing a home’s privacy, providing owners with times of serenity when they desire, and securing their interests
- Aesthetics – There is a wide variety of window styles, shapes, and sizes available to homeowners, allowing them to improve aesthetics without sacrificing functionality.

- Frame – the precise opening created by the head, jambs, and sill through which a sash of window fits.
- Pane – a piece of glass with a frame inside a window frame.
- Sash – a single styles and rails assembly that has been transformed into a glass-holding frame.
- Sill – the main horizontal component that makes up the bottom of a window frame.
- Mullion – a vertical bar placed in a window’s space between the glass panes.
- Transom – a horizontal component placed between 2 window units.

Selection of a window
The following are a some of the factors you need to keep in mind while selecting a window for an appropriate location:
- Condition of the Climate – Frames and shutters made up of steel are not a good choice for areas that are closer to the sea, because they are susceptible to corrosion. Hence, it is necessary to use a material that is not susceptible to corrosion in these areas. In extreme climatic conditions (either hot or cold), the dimensions of the windows should be such that the external environment has the least effect on the environment within the house. Similarly, in a moderate climate, the amount of sunlight entering the house must be taken into account when choosing the location for glazing.
- Purpose and position – Open doors only when necessary and for the intended use. As an illustration. Interior doors are not the same as exterior doors, which may have two completely different sets of requirements. Always choose a durable material for exterior doors, and secure fastening is always preferred. Conversely, interior doors should be lightweight enough for all members of the family to handle without difficulty.
- Used material type – It is essential to choose the material with care. Heavy wood, steel, glass, or fiberglass construction are good materials that will last for many years.
- Architectural perspective – Finally, choose the style, including the color scheme, of the door or window, which depends on the individual’s preferences and taste.
