Window technology has evolved over the years to the point where windows can be selected not only for their aesthetic qualities, but also for their performance abilities. For example, windows can be made from laminated glass that resists impact from flying debris in hurricanes, have special coatings that control the amount of heat gain and loss, or prevent water spots and dirt accumulation.
Insulating Glass Performance
Here are some terms you should know when shopping for high-efficiency thermal windows:
U-Value - A measure of efficiency. A lower number means the glass is more efficient.
Solar Heat Gain Coefficient - A measure of the heat added to your home via natural sunlight. A lower number means you will gain LESS heat.
UV Transmittance - UltraViolet light (UV) is what fades your carpet, drapes, and upholstery. The lower the % transmittance, the less UV light will get into your home.
Specialty Window Coatings
Low-E Coatings can be used to boost the energy efficiency of windows. Low-E double pane windows, most common in cold and moderate climates, are more energy efficient than clear windows because the low-E coating reduces heat loss through the window.
Solar control glass, also called Low E2, is a good glass for hot climates because, in addition to improving the insulating ability of windows, it also limits solar heat gain by blocking passage of infrared and some ultraviolet rays. Solar control glass allows a higher level of visible light to pass through a window with less solar heat gain reduction than tinted window coatings.
Hydrophilic Coatings
Lastly, a new glass coating is available that sheds water more quickly than standard glass and resists water spotting and dirt accumulation. A thin, invisible layer of silicon dioxide, applied to a window’s exterior, makes the surface smoother than conventional glass and hydrophilic.  Rainwater collects in sheets, slides off glass quickly, and actually cleans the surface more readily than conventional glass.
