Two panes of glass with a thin layer of separation allows space for an insulating gas between them. Low E, or Low Emittance, is a razor-thin, colorless, non-toxic coating applied to window glass to block infrared light from penetrating the glass from the outside. This means:
During seasonal hot and cold temperature swings, it’s important to produce an air-tight building envelope. Spray foam insulation outperforms other types of insulation because it can expand and tightly fill crevices that might otherwise have been left exposed.
