EXTERIOR INSULATED IN-FILL PANELS
The Endurex 530 is a fire-resistant, sound-reducing panel that can be glazed into acoustical window or curtain wall systems. The panel is fabricated with sound resistant substrates and a fire-resistant insulating core. It is most often used when maximum fire-resistance is desired. Often used for schools and hospitals, the Endurex 530 is Class "A" Fire-Rated and carries a limited 5-year warranty with the standard Polyester Paint Finish in either smooth or embossed aluminum. Endurex 530 panels are manufactured to meet the requirements of a standard 1" insulated glazing panel. Panels can be up to 4 1/2" in thickness with an STC rating up to 55. We presently have two STC rated panels tested in accordance with ASTM E-413: 3 1/4" thick with a tested STC rating of 42 and 4" thick with a tested STC rating of 45. Panels can be tested in other thicknesses and other panel make-ups to meet STC ratings up to 55.
