ADD-ONS Enhancements for Curbs and Curb Adapters Curbco offers various standalone enhancements to improve system performance and extend lifespan. Vib-Iso Rail System The VIB-ISO RAIL (VIR) system is designed to sit between an existing roof curb and curb mounted piece of equipment. The VIR is designed to reduce the vibration from a curb mounted piece of equipment to the building structure. Along with reducing the vibration from the roof-top-unit, the VIR also acts as a seismic and wind restraint to keep the unit attached to the roof curb. Each VIR system will be engineered to match the roof-top-unit and meet any customer requirements. The VIR system is available in either 1” or 2”deflection depending on the customer’s requirements. The VIR system is shipped nearly fully assembled with the springs and restraints installed at the factory to reduce onsite labor. On site, the VIR design allows for quick assembly requiring only basic tools to install it to the existing roof curb.

Prepackaged roof-top-units have a number of different components that can create mechanical vibration. Some of these can be individually isolated but most cannot. The simplest and most economical way to solve this issue is to place the entire unit on a vibration isolation rail. The VIR system uses coil spring as a resilient media to absorb the vast majority of the vibration energy emanating from the unit. The VIR system was designed using the latest in finite element analysis technology, more commonly known as FEA. The VIR seismic and wind restraints are integrated into the design allowing the rails to be shipped assembled with the restraints installed, thus ensuring proper installation of the restraints. Suggested Specifications Hurricane Clips Hurricane Clips serve as an extra measure of protection against hurricane force winds. These clips secure the RTU to the curb to avoid costly damage and repair were the unit to shift during a weather event. Hurricane clips also serve to protect the people and equipment inside a building should winds be sufficient to move the unit off of the curb, where it could fall through the roof structure. Gasket Material Gaskets serve to provide a water-tight seal at the bottom of the curb adapter where is connects to existing curb, and at the top where the HVAC unit rests. Extra gasket material for custom jobs or to replace weathered material is available. A LEGACY OF INNOVATION Our story begins in 1977, when Spring Branch Sheet Metal (SBSM) opened its doors as a Houston-based producer of all kinds of sheet metal products, from decorative awnings to kitchen hoods, before finally finding its true niche in roof curb space.
