Typically, an IGU consists of two or more panes of glass that are hermetically sealed around their edges. The space between these panes is filled with air or an inert gas, such as argon or krypton, which has a lower thermal conductivity than air. This gas-filled cavity reduces heat transfer between the indoors and outdoors, significantly enhancing energy efficiency. Moreover, the external and internal surfaces of the glass may be treated with low-emissivity (Low-E) coatings. These coatings reflect infrared energy, further improving the thermal performance by keeping heat inside during the winter months and blocking it during the summer.

Around the first year of the AD, due to the promotion of the Romans and their strict production process, glass achieved great success. Glassblowing (a technique brought to Rome from Syria) enabled artisans (often slaves) to make glass cups and bowls much faster than before. Cheap glasses began to appear on the market. Soon, the popularity of glass among ordinary Romans rivaled that of ceramics. Artists began experimenting with richer forms of art with glass, creating Rose Janus face vases and wine bottles decorated with scenes of nativity. Builders began to use glass for Windows, but because the glass was cloudy and heavy, the purpose was not so much for lighting as for safety and insulation. We find traces of glass Windows throughout Rome and surrounding cities, including luxurious tiles and well-preserved bathhouses in Pompeii.
