What Is Window?

A window is defined as a vented barrier secured in a wall opening. A window’s main function is to allow the entry of air and light into the building and give a view of the building’s outside. Other purposes of windows are to provide sufficient insulation against heat and cold, and in some cases, sound too. In this article, we will briefly discuss different types of windows used in homes and buildings.

A window is divided into two parts.

  1. Window frame

The major drawback of the fixed window is that it does not allow air movement through it. So, fixed windows are used where ventilation is not required.

2. Pivoted Windows

In this type of window, the shutter is fixed with a pivot on two opposite sides. With the help of pivots, the movement of the shutter is possible, either horizontally or vertically.

The movement of such windows ranges from 90 degrees to 180 degrees. The frame of pivoted windows has no rebates present on it.

The pivoted allows the air to ventilate through it, as can swing from a fixed pivot on either side of the frame. The pivoted windows are mostly used for the purposes like cleaning, maintenance, and emergency ventilation.

3. Double Hung Windows

The double-hung window consists of a frame and pair of shutters which are arranged one above the other. Double-hung windows can only move vertically within the grooves provided in the window frame.

Both the shutters of the windows are movable so ventilation is possible from the top as well as the bottom part of the window.

It is easier to control ventilation in this type of window as it can be opened at the top and bottom to any desired extent. Cleaning the double-hung window is a lot easier. The double-hung windows are ideally seen in the patios and walkways as it remains flush with the wall.

They can move in either a horizontal direction or a vertical direction. Suitable-sized openings are left on the walls to accommodate the shutters of the window.

Sliding windows are usually seen in homes, offices, bank counters, trains, buses, shops, etc. The major disadvantage of the sliding window is that its bearings can be damaged due to the dust particles in its frame.
