Today's residential solar control window films offer the homeowner an impressive array of technologies, which improve window efficiency by blocking 99.9% of the Sun's ultraviolet rays, rejecting up to 79% of the heat gain from sunlight, and eliminating glare. These films are designed to increase the "usability" of your home's natural lighting. By eliminating the negative features of natural light, your windows can be left uncovered; free of window treatments that interfere with your view, without the worries of outrageous cooling costs and faded furniture and carpeting. Our previous residential customers report saving as much as 32% on their electric bill after we treated their windows-certainly a dramatic example of savings, but representative of payback projections.
