Spectrally selective glazing: More daylight, less heat gain New
developments in spectrally selective low-e glazing offer
unprecedented levels of daylight with minimal solar heat gain.

handful of projects in the U.S. that feature the latest in
spectrally selective low-e glazing: triple-silver-coated glass.

The nanomaterials revolution has brought many innovations to the
building sector in recent years—concrete that cleans itself,
glass that switches from transparent to opaque with the push of
a button, and solar panels as thin as paper. One of the more
notable nanomaterial successes in the building industry dates
back to the late 1970s. That's when scientists discovered that
by applying nanometer-thick films—for the record, a nanometer is
a billionth of a meter—of metal and metal oxide to glass, they
could block high levels of h
