It is an opening that is engraved in a wall or roof that stands for a window. The basic purpose to have a window is to work as a natural ventilation system for air, an opening for incoming light, and give a spectrum view of the outside.

Like the doors, windows are a crucial part of the house. It is considered one of the most important elements of house making as well as the aesthetics of the house. Special windows make the house look special and eye-catching. So the profuse relevance of windows in the exterior and the interior design can not be disregarded.

Selection Criteria for a Window

Selection Criteria for a Window

Before making a window one must be careful as the uses of windows differ. Various types of windows are there and each type of window has its different use. Some such criteria are given below which must not be overlooked.

  1. Purpose- It is crucial to select the purpose of a window as the purposes differ so do the type of windows. For different purposes, different types of windows are made. And the places of the windows differ too. If the purpose of the window is to let in sunlight for the day then the window must be situated on the southeastern side of the house. If the purpose is to get a look at the rising sun then it should be placed at the ease of the house from where the sun can be seen in the morning. If the purpose is to get a cold or warm breeze then it should be placed on the side from which direction the air usually blows. And some would prefer their window in the southwest of their house as it will enable the homeowner to take a view of the setting sun.
  2. Climate– Climate plays a vital role in all over making the house. From the design to choosing the used material, climate conditions must be considered. So as with windows. The place, dimensions, and material of the window should be used according to the climate. If you live in a house that is situated in a hot prone area then you must not consider your window to be in the southeast or on the southwest side as it is going to let in a lot of sunshine throughout the day and thus making the environment inside your house impossible to live in. On the other hand, if you live in a colder region then you always should go for a window placed in the southeast and the southwest. For the materials, climate also needs to be looked at. If the climate is humid or moist like the places that are situated near the sea, materials that are not theatrical to corrosion should be used.
  3. Location- similar todoors, windows are also needed to be placed in the places which are best for the desired purpose for which the window is made. The windows make the appearance of the house look good and also unknowingly catch the visitor’s eyes. If placed wrongly, the exterior looks and the desired aesthetics of the house could be ruined. So it is necessary to place the windows in the right places. Also, the location of the windows must not be inaccessible as cleaning the windows is a mess and takes a lot of care. So windows must be made in places that are easily accessible.
  4. Noise Isolation- noise isolation is a crucial matter of fact as disturbing noises can ruin your mood as well as health. Also, noises from outside can spoil your concentration while performing important tasks such as reading. So windows must not be placed at a side in which there is a continuous source of the noise. If any religious place is noisy like a temple, church, mosque, or other sources like a railway line, railway track, or even a high road, a market is near your house then you should not consider making windows on that side of your house. Noisy places need thick glassed windows as glass is a good insulator of sound.
  5. Air Infiltration – a window is the best way to get air ventilation to your room so it is important to consider a window on the side of the airflow.
  6. Water Penetration – windows must resist the unwanted airflow and water intrusions during the time of a cyclone or thunderstorm or even rain. Water can damage the floor and unwanted airflow can harm the inside of the room as during cyclones winds usually bring a lot of dust with them.

So a window must be largely sturdy to resist the water penetration and provide perfect insulation from the outside calamity. Also, precautions need to be taken in case the window glass does not bump into the wall and break( if the window is openable)

Modulating the Façade of the House- windows can alter the perception of a house or building depending upon its type, placement, material, glass color, number, and articulation. It plays a heavy role in modulating the façade of the house.
