You can think of Awning Windows as an alternative to other windows, swinging outwards from the bottom, hinged at the top to allow for motion to the outside. At one point in time, they were very common and popular in schools, manufacturing plans and some home designs. Still, you sometimes find these older style designs in some newer homes and condominiums. Mainly, you will find such designs placed in homes with temperate climates. Depending on the design, you will find some that can be opened manually with a hand crank, or some that are operated with pull chains.
In the early decades of the previous century, Awning Windows were very common in schools and manufacturing plants due to their ability in cooling down the interior, increasing and improving air flow within the space. I school environments, they needed to maintain a good flow of air in order to maintain the health of the children in schools and provide a comfortable learning environment. Conversely, this was the reason they were used in production environments, requiring an improvement of airflow to maintain a comfortable work setting for employees.
In some cases, you could find a set of Awning Windows in a larger space reaching the height of the ceiling, which was operated by pull chains or some sort of pulley system. This was done in order to provide for greater ventilation for larger space, and offering a better flow of heat and cold, depending on the desired result. With such designs, homeowners can take advantage of this design at times of rain, where you can retract a window far enough to still leave a breeze coming through with a whiff of fresh air at any time of the day. With the advancements of technology, windows have become less popular and less in favour than others.
However, there are many benefits to using Awning Windows in place of air conditioning and ventilation technologies. The fresh air you can acquire from the natural breeze is advantageous to many living conditions, and many prefer the fresh smell of nature rather than the circulated air you get with mechanical systems. Think about the look of your home, the natural breeze and the advantage a natural flow of air can add to the atmosphere within your home.
