PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
Vaulted or cathedral ceilings introduce unique challenges and opportunities when integrating aluminum ceiling panels, as the angled slopes and high peaks demand customized suspension layouts to achieve a seamless appearance. Unlike flat ceilings, these geometries require tapered or stepped aluminum main runners that follow the roofline, ensuring that panel joints remain flush and linear over the entire span. Precision laser cutting of aluminum channels is often necessary to accommodate varying slopes, particularly at the ridge where panels from opposite sides converge. In addition, custom transition mouldings help maintain clean sightlines and consistent reveals, visually unifying the panel pattern from the lowest soffit to the ceiling apex.
Structural support is another crucial consideration: the aluminum rigidness must compensate for gravity loads on angled planes. Installers typically use heavier gauge suspension wires, spaced closer together at higher elevations to prevent panel deflection. Perforated aluminum panels can be incorporated for ventilation or acoustic treatment, but the slope must be angled correctly to avoid trapping condensation or creating uneven acoustic reflections. Attachment to the underlying structure must also account for thermal expansion—aluminum’s coefficient of thermal expansion can cause slight dimensional shifts in vaulted spaces, and expansion joints should be placed at calculated intervals. By leveraging aluminum’s lightweight nature and strength, designers can create dramatic cathedral ceilings that maintain uniform lighting distribution, ease HVAC integration, and deliver a polished, contemporary finish aligned with both functional and aesthetic goals.
