Smoke & Vent Prismatic Skylights
Nucor Smoke & Heat Vent Skylights are designed to open automatically, releasing heat, smoke, and noxious fumes during a fire. Engineered to withstand severe weather conditions, Nucor’s Smoke & Heat Vent Prismatic Skylight features a double-glazed prismatic lens that achieves not only a Class 4 hail zone glazing rating, but also a CC1 fire rating.
Fully Assembled SMoke Vent Skylights, Ready for Installation
Available in two standard sizes, Nucor smoke vents are UL and/or Factory Mutual rated, fully glazed and ready for installation. The smoke vent frames are fabricated from 6061-T6 aluminum with a natural mill finish. Our frames have integral condensation as well as weepage gutters, which drain interior moisture to the outside.
High Performance Smoke & Vent Skylight Design
Nucor’s Smoke & Vent Prismatic Skylights operate by a fusible link with a minimum temperature rating of 165°. The fusible link mechanism, with gas shocks, includes an exterior manual release cable for testing. The vents open to a minimum angle greater than 90°. Our vents are double glazed, using SR40 100% Impact Modified Clear Prismatic or Polycarbonate over SR25 white prismatic lens. They are CC1 rated, glazed in a Signature Series Dome configuration.
