Glass is no longer merely a window to the world in contemporary architecture and design—it's an integral element for energy efficiency, beauty, and occupant comfort. Glazing units, in homes and businesses alike, have come a long way from mere transparent slabs. From basic double glazing to sophisticated innovative technologies, these units are the perfect example of how innovation can turn both form and function into works of art.
From Old-Fashioned Double Glazing to Smarter Alternatives
Traditional double glazing—two pieces of glass with a spacer in between—has been the benchmark for insulation for many years. Though effective, its performance criteria have been bested by more recent technologies. One of the most important test criteria for thermal performance is the U-value: the smaller the number, the smaller the amount of heat lost. While uncoated double glazing typically has a U-value of about 2.7 W/m²K, newer options can reach much lower values.
Enter next-generation glazing that inserts an invisible suspended film between the panes to serve as a third insulating layer. This technology significantly reduces the U-value to around 0.4 W/m²K. The homeowner can thus look forward to much lower energy consumption, lesser CO₂ emissions, quieter rooms, and reduced dependence on heavy or thick frames—without the compromise on looks.
Beyond Insulation: Heating and Climate Comfort
Thermal performance is not the sole territory in glazing innovation. Heated glass, for example, combines conductive coatings that produce heat when electrified. This enables the glazing itself to be used as a heating element—perfect for airy conservatories, glass-intensive modern extensions, or areas where traditional radiators could clutter up the space.
The advantages extend to increased comfort and climate management. Heated glass eliminates the condensation accumulation that leads to foggy surfaces where there is high humidity, such as in kitchens, bathrooms, or spa spaces. Heated glass can also serve as an anti-chill layer, reducing cold spots around large glazed spaces, and can even function as an ice- or snow-defrosting system in cold climates.
