The heavy fixed lite (picture) windows incorporate a heavier 4 inch deep frame and offer 3/4-hour Underwriter’s Laboratory rated protection. They are ideal for inclusion in rated corridors or exterior walls where it is essential to provide natural light or viewing capabilities but ventilation is not required. These fixed lites may be mulled with H925 operable Fyre-Tec window to provide a larger opening with greater daylight area as well as ventilation.
