Read full description

The 8000 Series is a thermally broken operable vent intended for coordination with compatible storefront and curtain-wall subframes. Equal-leg and unequal-leg subframes address the documented integration conditions, using 1 inch glazing infill. The available air/water report records 0.133 L/s·m² air infiltration at 75 Pa, no water penetration observed at 720 Pa and no structural breakage at 3360 Pa for its tested specimen and conditions. A separate NFRC report models U-values as low as 2.320 W/m²·K for the documented configuration. These results do not establish every size or installed condition. Confirm size, glass, hardware, interfaces and project requirements against current documentation.
