Glass remains the pivotal material that bridges our exterior and interior environments. But it also continues to play a significant role in shaping the efficiency, safety, and aesthetic appeal of residential and commercial windows.

In this article, we’re offering a few insights into the common types of glass used for windows, encompassing historical variants and contemporary innovations, with the hope that we’ll be equipping homeowners, architects, and contractors alike with an in-depth understanding of the diverse range of glass available. As experienced window manufacturers, we’ll also delve into some of our signature offerings for maximizing energy efficiency and visual elegance.

The Evolution of Window Glass

The story of window glass is a testament to human innovation and technological advancements. Early windows were predominantly crafted from simplistic materials like paper, cloth, and wood, serving as precursors to the evolution of sophisticated glass-making techniques. As the demand for natural light, thermal insulation, and enhanced safety grew, the industry witnessed the emergence of historical types of glass, including:

  • Quarry Glass: Among the earliest forms of glass, quarry glass was opaque and uneven, made by combining sand, lime, and soda and heating it up at high temperatures.
  • Crown Glass: Originating in the 17th century, crown glass was crafted by creating a large glass bubble that was then spun rapidly to form a flat disk. The outer portion was cut into window panes.
  • Cylinder Glass: A more efficient method than crown glass, cylinder glass involved blowing a long cylinder, which was later flattened into a sheet, offering improved clarity and consistency.
  • Float Glass: Representing a modern glass-making technique, float glass involves floating a thin layer of molten glass on a bath of molten tin. This method leads to a uniform, smooth surface, setting the standard for contemporary window glass.

Surveying Modern Innovations in Window Glass

As advancements in glass technology continue to redefine the realm of window design, we now embrace diverse contemporary types of glass to optimize functionality and elegance in our offerings (after all, we wouldn’t be one of the leading awning, bay, specialty, and casement window manufacturers in the GTA if we didn’t!). The current spectrum boasts a myriad of glass options, with each type offering unique characteristics and applications. A few notable examples include:

  • Low E Glass: Acclaimed for its energy-efficient properties, Low E (Low Emissivity) Glass integrates a microscopic coating that reflects heat, facilitating superior energy conservation and indoor climate control.
  • Insulated Glass: Comprising multiple glass layers separated by an air or gas layer, insulated glass mitigates heat transfer, making it an optimal choice for enhancing thermal efficiency in diverse climate conditions.
  • Tempered Glass: Community-certified for its sturdiness and resistance to breakage, tempered glass is formed by heating glass to high temperatures and then rapidly cooling it, making it ideal for applications requiring enhanced safety (i.e., where durability and break-resistance are paramount).
  • Laminated Glass: Positioned as a hallmark of safety and security, laminated glass combines multiple layers of glass with a durable interlayer of plastic or resin, fortifying windows against impacts, breakages, UV rays, and external noise infiltration, making it a versatile choice for modern windows.
