Cool roof technology is increasingly popular as more contractors increase roof insulation to reduce HVAC capital expense and year-round operating cost.
While skylights are desirable for their ability to bring light into otherwise dark interiors, they also can function as roof-top solar collectors and hinder the ability of cool roof technology to help reduce air conditioning operating costs. If the daylighting benefit is to outweigh the negative impact on the overall energy performance of a cool roof, skylights need to maximize visible light transmission while minimizing solar heat gain.

This means that in the evening and winter, more heat in a home or building escapes through a sloped skylight than it does through a vertical window using comparable insulating glass. And during the day, more outdoor ambient heat passes into a structure through the glass in a skylight than through similar glass in a window.

In addition, the suspended film practically eliminates ultraviolet radiation that can cause fading, and because the film is clear and colorless, it maintains visual clarity and normal color rendition. Film-based multi-cavity insulating glass has been saving energy in thousands of homes and in such landmark buildings as the Hoover Dam Visitor Center, the Boulder, Colorado, Municipal Library and in the National Gallery of Art in Washington, D.C.
