What is solar radiation and ultraviolet (UV) rays?

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…

What are warm edge spacers?

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.…

What is argon gas?

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)…
