Colt Firelight glazed, natural ventilator installs in a glass atrium or directly onto a roof. The dual-purpose product provides buildings with day-to-day ventilation and smoke control to aid building evacuation in the event of a fire. Available in single-or double-leaf design and with control options for automated climate control, the product provides fresh air and natural daylight. Designed for high aerodynamic, acoustic, and thermal performance, the ventilator is available in a range of standard designs. Powder-coat finish can be specified. A thermally broken design minimizes heat loss for maximum energy efficiency. The ventilator uses standard manual operation and can be specified for electric or pneumatic operation.
