Spectrally selective glazing: More daylight, less heat gain

Post Time:Feb 17,2009Classify:Industry NewsView:129

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 heat-generating infrared light, while allowing most visible light to pass through. The discovery led to the development of thin-film-coated spectrally selective low-e glasses that offered Building Teams a near-crystal-clear glazing alternative to traditional multi-pane insulating glass units that use tinted or mirrored glass to control solar heat gain, according to a Feb. 17 BDC Network report.
