Roofs Curbs with Spring Isolation



Removable Lift Eyes


Adjustable Load
Vibration Isolation Springs

The Vibro-Curb® III incorporates adjustable spring isolators and a roof curb into a single unit. The vibration eliminating portion of the Vibro-Curb® III is constructed of structural steel and it's designed to match the bottom of the rooftop unit. Typical fabrication time is only 7 to 14 days.

The rooftop unit can be mounted immediately after the curb is installed and roofing can be completed at a later date without disturbing the unit. This reduces the additional crane or helicopter expenses.

New, flexible 8" counter flashing provides a weather seal and easy access to the spring isolators for adjustment or replacement. This eliminates having to roof around spring access ports. The isolators are custom sized and spaced to accommodate the roof-top's weight and center of gravity for a minimum 90% isolation efficiency.

Vibro-Curb® III features a wood nailer for attaching roofing felts. Standard height is 24", with options for different heights... and can be fabricated to match a specific roof pitch. The unit may be factory assembled and shipped in one piece... or shipped in a limited number of sub-assemblies.
