The 5500 fixed windows are designed with performance in mind. These windows perform so well in NFRC thermal tests that they have been used in 5-Star Green Building projects, Net Zero housing and numerous LEED certified projects.
Our primary focus has been to manufacture energy-saving window and door products. Throughout our history, we have established ourselves as an innovator in the design and manufacturing capability of insulated windows and doors.
