The Use of Double Glazing in Industrial Buildings During the 1930s


Origins and Early Development

The concept of double glazing has been around for centuries. However, it was not until the 1930s that this method of insulating windows became more widely known and adopted. Double glazing technology was developed in the United States by C.D. Haven, who patented an invention called “Thermopane” in 1930. Thermopane was developed as a means to insulate windows by trapping air between two layers of glass, thereby reducing heat transfer between the interior and exterior of a building.

The early development of double glazing technology involved two sheets of glass separated by a spacer bar and a layer of desiccant to prevent condensation. The innovation in the 1930s involved creating a vacuum or gas-filled space between the glass layers, which further enhanced the insulating properties of the window. In the early stages, krypton and argon were the main gases used, while today, argon continues to be the most widely used gas.

During these early years, the double glazing industry was relatively small, with only a few companies producing these specialized windows. As the technology advanced and became more accessible, an increasing number of manufacturers entered the market and started offering double-glazed products at more attractive prices.

Double Glazing Technologies in the 1930s

The use of double glazing can be traced back to the 1930s. Double glazing refers to the technique of using two panes of glass separated by a spacer, with the space between them filled with air or an insulating gas. This space creates a barrier, reducing the transfer of heat and noise between the interior and exterior of a building. This section will discuss the advancements in glass technology, sealing techniques, and spacer bars and gas fillings that were prevalent during the 1930s.

Types of Glass Used

During the 1930s, the most commonly used glass in double glazing systems was annealed glass. Annealed glass is created by a slow cooling process, which allows the glass to be cut and shaped more easily. This made it a popular choice for use in windows as it could be easily customized for different building designs.

Another type of glass used during the 1930s was wired glass. Wired glass featured a grid of wire mesh embedded within the glass, providing added strength and durability. This type of glass was mainly used in commercial and industrial buildings where safety and durability were a priority. However, it was not a suitable option for residential double glazing due to the reduction in clarity caused by the wire mesh.

Additionally, there was the use of obscure or patterned glass. This type of glass featured a pattern, texture, or design on the surface of the glass, providing privacy while still allowing natural light to filter through. While this glass was mostly used to provide privacy, it also added a decorative element to the double glazing.

Sealing Techniques

The sealing techniques used during the 1930s differed significantly from the methods used today. In the early days of double glazing, the two panes of glass were typically held together by wooden muntin bars or metal glazing bars. The space between the panes was not hermetically sealed, and as such, humidity and air permeation were common issues.

To combat this, lead came or putty was used as a sealant to create a weather-tight seal between the glass and the window frame. However, this method was prone to deterioration over time, resulting in the need for regular maintenance and eventual replacement.

Another sealing method used during this time involved a metal or rubber gasket set into a groove in the window frame. This gasket was then compressed by tightening screws or clamping the glazing units in place. While more effective than lead came or putty, this method still had issues with maintaining an air-tight seal over time.

Spacer Bars and Gas Fillings

Spacer bars in the 1930s were typically made of wood or metal and were used to maintain a consistent distance between the two panes of glass. The space created between the panes played a crucial role in providing the insulating benefits of double glazing, as it acted as a barrier to heat and noise transfer.

The 1930s did not yet see the introduction of the insulating gas fillings commonly used in modern double glazing systems, such as argon or krypton gas. Instead, the space between the panes was filled with air. While this still provided some insulation, it was not as effective in reducing heat transfer as the inert, heavy gas fillings used today.

In summary, double glazing technologies in the 1930s marked the beginning of a significant advancement in the construction industry. Though the types of glass, sealing techniques, and spacer bars and gas fillings were less advanced than those utilized today, they laid the foundation for future developments in double glazing technology. Over time, these developments have led to the high-performance, energy-efficient double glazing systems we see in modern buildings today.
