One of several new technologies appropriate to residential applications is the high R-value and Low E windows. High R and Low E is an abbreviated way of referring to windows that have high resistance to conductive heat transfer (high R value) and low radiant emissivity (Low E). Some of these windows are very expensive and may not be cost effective for south Florida applications but more suited for harsh. Several manufacturers are developing intriguing glazing systems for windows that reduce solar heat gain without significantly reducing visible light transmission. These manufacturers claim that windows can be tuned to block solar gain in the summertime to reduce cooling loads and maximize solar gain in the wintertime to take advantage of solar heating.
