Thybar Corp.: Rooftop HVAC Unit Curb

July 30, 2007


Vibro-Curb is a curb that provides mounting for rooftop HVAC units. The device has integral, vibration-dampening spring isolators that can be easily accessed. Roofing may be completed at a later date without disturbing the unit, which eliminates extra crane or helicopter expenses. A 2 by 2 wood nailer is provided for attaching roofing felts. The flexible 9-inch counter-flashing provides a weather seal while permitting easy access to the isolators. The isolators are custom sized and spaced to accommodate the rooftop unit’s weight and center of gravity for optimum vibration dampening. Deflections of 1, 2, or 3 inches may be provided. Standard 1-inch deflection curb height is 21 inches, with optional heights available. Vertical limit stops eliminate excessive movement caused by wind loads and seismic activity.
