VibroCurbIIIvibro

General Information

Vibro-Curb III ™ incorporate adjustable spring isolators and can ship as a single piece unit. RTU can be mounted immediately after the Vibro-Curb III ™ is installed and roofing can be completed at a later date without disturbing the RTU. This process will reduce installation costs and expedites the installation process. Flexible counter flashing provides a weather tight seal and easy access to the isolation springs. Isolators are sized and spaced to accommodate the rooftop weight and center of gravity for a minimum of 90% isolation efficiency.
