Since the advent of insulating glass, many new options in glazing have become available to the consumer. You have probably heard the terms Low E (Low Emissivity) and Low E2; these are the most frequently used options in glazing for residential buildings. These glazes reflect heat energy back to its source. Low E windows reflect radiated heat and reduce solar heat gain in varying degrees, depending on the type and angle of the sun’s rays—low in wintertime and high in summertime. Thus these windows keep you cool in the summer and warm in the winter.
Low E2 coatings also reduce the level of UV rays that pass through your windows so your interior furnishings are less likely to fade.
Other types of glazing that are available include Laminated Glass, Sun 145, etched glass, and leaded glass. If you have questions about glazing on specific elevations, contact us and we can discuss the various options with you.
