Did you know that clear glass transmits up to 90% of solar radiation. It either absorbs or reflects only 10% of solar radiation.You would think since clear glass can transmit solar radiation in, it can also transmit it back. The beauty is that, it doesn’t, after solar radiation is transmitted through the glass and absorbed [...]

Insulated Window Glazing or Glass
Insulated window glazing refers to windows with two or more panes of glass. They are also called double-glazed, triple-glazed, and—sometimes more generally—storm windows. To insulate the window, the glass panes are spaced apart and hermetically sealed to form a single-glazed unit with an air space between each pane of glass. The glass layers and the [...]
Low-Emissivity Window Glazing or Glass
Low-emissivity (Low-E) coatings on glazing or glass control heat transfer through windows with insulated glazing. Windows manufactured with Low-E coatings typically cost about 10%–15% more than regular windows, but they reduce energy loss by as much as 30%–50%. A Low-E coating is a microscopically thin, virtually invisible, metal or metallic oxide layer deposited directly on [...]
