Less than half of the sun's energy is visible. Longer wavelengths beyond the red part of the visible spectrum are infrared, which is felt as heat. Shorter wavelengths, beyond purple, are ultraviolet (UV). When the sun's energy strikes a window, visible light, heat, and UV rays are reflected, absorbed, or…

Windows are thermal holes. An average home loses approximately 30 percent of its energy through them. So it goes without saying energy-efficient windows save money. The additional amount spent for a solid, energy-efficient window will pay for itself in two to four years. Long-lasting windows cost less in the long…

Low-e glass improves the insulating value of a window, roughly as much as adding an additional pane of glass. Low-e glass combined with argon gas boosts energy efficiency by nearly 100% over clear glass. Like all gases, argon gas will leak from the window over time. However, it is non-toxic…

The main advantages are: Reduced energy loss (heat and cold) Reduced harmful ultraviolet (UV) rays Improved environmental footprint

We often see condensation and frost on windows, usually around the edges of window glass. The edge is where the panes of the sealed units are held apart by spacer bars. Condensation is the primary reason for window-related call-backs. Non-conductive warm edge spacers reduce heat transmission of heat, limiting condensation.…

Argon is an odourless, colourless, tasteless, invisible, non-toxic gas used to replace the air inside sealed window units to reduce thermal transfer. It is six times heavier than air. Since argon gas is denser than air, and not in continuous motion like air, the transference of energy (heat and cold)…
