Radiation is the movement of Overunity Generator Guideheat as infrared energy through the glass.Convection occurs when air gives up its heat to the cooler glass and sinks toward the floor - this movement sucks new, warmer air toward the glass that is in turn cooled, creating a draft.

Air leakage, more self-explanatory than the rest of the terms, is simply the passage of heated air through cracks and around weather-stripping.Reducing one or all four ways that windows can lose heat can help lessen the U value of your windows. The U value is scored on a scale A low U value, like.25, indicates good insulation.

Decrease the U Factor Increase Efficiency You can decrease a window's U factor by coating your windows with low-emitting (low-E) coatings. Low-E coatings are metal or metallic oxide layers on a window surface that reduces radiative heat flow. There are a variety of applications of low-E coatings that are dependent on geographical location and personal preferences regarding the temperature of your home. Three of the main applications of Low-E coatings are Double-Glazed with High-Solar-Gain Low-E Glass, Double-Glazed with Moderate-Solar-Gain Low-E Glass, Double-Glazed with Low-Solar-Gain Low-E Glass. Higher solar-gain glazing tends to perform better in winter, while lower solar-gain glazing tends to perform better in the summertime.
