Better Rooftop HVAC
The Vibro-Curb, available from Thybar Corporation (Addison, IL) has integral, vibration-dampening spring isolators that can be easily accessed. The curbs provide mounting for rooftop HVAC units, and they allow roofing to be completed at a later date. The flexible 9” counter-flashing provides a weather seal while permitting easy access to the isolators. A minimum 90 percent efficiency can be achieved when using the isolators, and they can be custom-sized and spaced to accommodate the rooftop unit’s weight and center of gravity. Other benefits include:
- The possibility of deflections of 1”, 2”, or 3”, along with vertical limit stops that eliminate excessive movement caused by wind loads and seismic activity.
- The ability to fabricate the units to match a specific roof pitch or configuration.
