Unique Metal Works is working on the third and final phase of their sheet metal scope for Lincoln High School. Shown here is insulated rooftop ductwork which will supply air to classrooms and labs. The white protective covering is an added level of protection for the insulation. This phase of the ductwork feeds the area from two dedicated outdoor air systems (DOAS) units by conditioning the outdoor air and recirculating it independently. The units then separate the sensible and latent loads removing humidity and adjusting air temperature.
