For protecting roof top equipment and intake/exhaust shaft penetrations, our penthouse solutions are are designed the same benefits as our louvers. Our extruded aluminum penthouses offers the Architect and Mechanical Engineer an attractive fully functional alternative to unsightly roof mounted hoods or shop fabricated goosenecks. This is especially important when these items can be viewed from the ground or taller adjacent buildings. These low silhouette architecturally appealing housings are ideally suited as fresh air intakes, exhaust vents, pressure relief vents or as attractive enclosures for unsightly rooftop mounted equipment. Options include mitered corners (pictured), box corners and a drainable model.
