Aluminum Windows History:

In historic preservation, aluminum windows are generally thought of as replacement windows, common since the 1970s. Many people are surprised to learn that aluminum windows in buildings have been around since the 1930s and that numerous landmark buildings in the 1930s and 1940s prominently featured them in their design. After World War II, aluminum windows gained more widespread use in the construction industry and soon surpassed steel window sales.

By the 1970s, they rivaled the dominant wood window industry, particularly in commercial and institutional construction. The historic significance of early aluminum windows is now being recognized and efforts are being taken to preserve and rehabilitate them.Aluminum windows actually appeared as early as 1912 for use in railroad cars,streetcars, and buses. The Union Pacific Railroad touted them in their modem streamlined trains for their "high efficiency as to weather tightness, great ease of operation, low up-keep costs,great strength and beauty."

It was the modern look and appeal of aluminum that helped generate a market in the 1930s for aluminum windows in buildings, particularly in signature buildings and high-end projects. By 1932, the Aluminum Company of America (ALCOA) was running separate full-page advertisements in Architectural Record proudly featuring buildings such as the Cities Services Building in New York City with its 2,652 double-hung aluminum windows and the Medical Center Building at Louisiana State University School of Medicine in New Orleans with its 570 windows (see Figure I).Leaving no opportunity to chance, manufacturers began offering aluminum windows that mimicked Colonial-style wood windows with true divided lights,and also casement, projecting, and accordion windows to compete against a
thriving steel window industry.

A 1932 advertisement for residential aluminum windows that appeared in the Architectural Record read: "It isn't a fad - it's just plain thrift to use building materials of Alcoa Aluminum ... Take casements for instance. Because windowframes,
sashes and sills made by Alcoa Aluminum are non-rusting, they won't drip stain and leave unsightly streaks on adjoining surfaces . . . " (see illustration above). Over time, aluminum windows even took on their own design, in contrast to the appearance of wood and steel windows.

Aluminum Windows Types:

Casement Window

The advantages of casement window are large opening area, good ventilation, good sealing, excellent sound insulation, heat preservation and impermeability. It is convenient to clean the windows with the inner open type, while the outer type does not take up space when opening. The disadvantage is that the window width is small and the vision is not wide. The opening of the external window needs to occupy a space outside the wall, which is easy to be damaged when the wind blows; and the inner window is to occupy part of the indoor space, so it is not convenient to use the screen window, curtain, etc. when opening the window, it is not convenient to use the screen window and curtain. If the quality is not up to standard, it may also seep rain.

Sliding Window

The advantages of sliding window are simple and beautiful, large window width, large glass block, wide field of vision, high lighting rate, easy to clean glass, flexible use, safe and reliable, long service life, opening in a plane, occupying less space, convenient installation of screen window, etc. The most commonly used by consumers is the sliding window. The disadvantage is that the two windows can not be opened at the same time, only half of them can be opened at most, the ventilation is relatively poor, and sometimes the sealing is also slightly poor. Sliding window: divided into left and right, up and down push-pull two kinds. Sliding window has the advantages of not occupying the interior space, beautiful appearance, economical price and good sealing performance. It adopts high-grade slide rail, which can be opened flexibly with a slight push. With large pieces of glass, not only increase the indoor lighting, but also improve the overall appearance of the building. The forced state of the window sash is good and not easy to be damaged, but the ventilation area is limited.
