Options that Increase Window Efficiency

Part 2 of Advances in Glazing Materials for Windows. Manufacturers usually represent the energy efficiency of windows in terms of their U-values (conductance of heat) or their R-values (resistance to heat flow). If a window’s R-value is high, it will lose less heat than one with a lower R-value. Conversely, if a window’s U-value is […]

Reflecting the Heat Away

Part 2 of Cool Your Home Naturally. Dull, dark-colored home exteriors absorb 70% to 90% of the radiant energy from the sun that strikes the home’s surfaces. Some of this absorbed energy is then transferred into your home by way of conduction, resulting in heat gain. In contrast, lightcolored surfaces effectively reflect most of the […]
