Different types and styles of windows are usually available in a wide range of sizes. The most common types are:

o Standard bonded windows, which are the most used today. They are available ready-to-use in a wide range of shapes and sizes, from leading flexible window manufacturers and builder dealers. Due to the versatility of the design, a variety of formats can be created using fixed, top-opening, and side-opening windows. Some modern sashes have “ easy clean ” projecting hinges, allowing both sides of the window to be cleaned from the inside

o Vertical sliding sash windows, with a very sophisticated design that combines a large glass surface with thin wooden profiles. An arrangement of ropes, weights and pulleys is used to counteract the weight of the sash and thus facilitate the opening and closing of the windows. Sash sliding sash windows have proven their reliability over the years. The main causes of the complaints were due to the window designer taking into account the thickness of the paint film. If the paint is applied excessively, the windows tend to stick. On the other hand, if the designer leaves a large space around the window for the paint film, the window may rattle. Modern exterior stain finishes overcome this problem by not building up on the window, so modern sash windows can be built to much tighter tolerances without sticking or rattling. This type of window is still very popular today, provides excellent control over ventilation, and can be double-glazed. In a modern version, the weights and pulleys are replaced by a pair of spiral blade scales. These balances eliminate the need for the jambs to be constructed to form the pockets for the weights instead of using smaller solid jambs ESWDA.

o Horizontal pivoting windows. This type of window is useful for situations where a large clear sheet is desired, but provisions must be made for cleaning both sides of the window from inside a roof window, for example.

o Lower sash windows generally open into the room. The tilt and swivel type, mainly available in uPVC, can also be opened from the side.

The most common variations are:

or arched windows, which are Georgian in style and are curved, hence their name. This type of window generally contains many small glass panes formed by using glazing bars to produce flat glazing areas rather than curved ones. The window can curve within the thickness of the wall or, as is more common, protrude from the facade of the house. Bay windows have a small flat roof that is usually covered with lead.

or windows, which vary greatly in plan and elevation. The most commonly encountered types are semicircular, segmental, extended, and square in plan. The bay can provide a window for the ground floor only, or it can extend to the top of the house. The shape of any roof over the bay ranges from flat roofs to some type of sloping roof that is similar in style to the main roof.

o Leaded windows, in which small crystals are placed between square or diagonal pen holders. The scaled units, used in replacement windows, can be fitted with slippery cables to simulate leaded lights.
