When choosing window joinery, we may encounter the term "standard windows". How do they differ from non-standard windows and what are their sizes? It turns out that these problems are not so obvious nowadays, and typical windows may vary slightly depending on the manufacturer. Therefore, we offer the sizes of standard windows and what to look for when buying.Until the 1930s, the windows were wooden. Over time, plastic usage methods became popular and the first PVC windows appeared on the market. Based on the size of the wooden frames, manufacturers of plastic windows have determined the typical window sizes so that different types of frames can be installed interchangeably in the window openings. Currently, this division is somewhat anachronistic and can vary from manufacturer to manufacturer. Moreover, there are no precise standards that determine the size of typical windows. However, it is worth familiarizing yourself with the parameters of the window frames so that nothing surprises us when choosing them.Typical and atypical windows
The standard windows were designed in such a way as to facilitate the replacement of window frames. Each type of window was assigned certain dimensions, such as width and height, the division of the window quarters, the distance from the axis of the fixed post, the method and direction of opening the window sashes. Thus, a typical window marked, for example, with the symbol O1, i.e. a single-leaf hinged window, can be replaced with exactly the same one-to-one window. It was known that its dimensions would not differ and would be 565 mm wide and 535 mm high.There are as many as 50 types of standard windows – each window differs in size, number of sashes and opening method. Single-leaf windows range in size from 565 to 1165 mm wide and from 535 to 2295 mm high. Double-leaf windows from 1165 to 2065 mm wide and from 1135 to 1635 mm high. In this case, windows with one sash can be swing-out, and windows with two sashes can be swing-out. Similarly, the unusual windows did not correspond to any of the listed types of typical windows.Standard Windows and Window Joinery Manufacturers
The concept of a typical window is still used, although window manufacturers usually do not adhere to strictly designated types. Most windows produced today differ slightly from the sizes considered standard, which is why a typical window from two different manufacturers may differ in size by several centimeters. The dimensions are usually rounded to full centimeters. For this reason, when buying new window frames, it is worth paying attention not only to the type of window, but also to its dimensions. Manufacturers may also have single-leaf windows, and typical windows with asymmetrical splits may be symmetrical in shape.It's the same with the opening method. While in standard types, single-leaf O1xBetdows could only be hinged, nothing prevents such a window from being swing-out. Currently, the opening function is a matter of choice for the person buying window joinery. Changing the typical opening method will not make the window atypical.Standard sizes of standard windows
As we have already mentioned, typical windows can have different sizes depending on the manufacturer. However, these dimensions usually differ slightly and are close to the typical dimensions. The sizes of typical windows, divided into single and double windows, are shown below. Due to the fact that the opening method can be freely chosen by the customer, we do not provide standard window opening methods.
