Isolated Curbs
Vibro-Acoustics Vibration Isolation Curbs (VCR) series come with integral and adjustable spring vibration isolators. Galvanized steel construction with a wood nailing strip for attaching field supplied and applied flashing is standard. VCR curbs can be constructed with a sloped bottom to match the roof pitch. As airborne noise and vibration are usually a simultaneous concern, complete systems are available incorporating vibration isolation, duct-borne noise control, radiated noise control and flexible connections. Noise control elements are aerodynamically matched to the connections between the rooftop equipment and the ducting system to afford the lowest possible installed pressure drop and energy usage.
