Window glazing a hardened putty that holds a pane glass in the frame. There are various types of window glazing. Based on window orientation, your building design, climate conditions you can select any of the following methods of window glazing.

Gas Fills:
To improve the thermal performance of windows with insulated glazing, some manufacturers fill the space between the glass panes with gas.

Heat absorbing tints:
Heat-absorbing window glazing contains special tints that change the color of the glass. Tinted glass absorbs a large fraction of the incoming solar radiation through a window

Insulated Window Glazing:
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.

Reflective coating:
Reflective coatings on window glazing or glass reduce the transmission of solar radiation, blocking more light than heat. Therefore, they greatly reduce a window's visible transmittance (VT) and glare, but they also reduce a window's solar heat gain coefficient (SHGC).

Low emissivity coating:
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%.
