TECO Metal Products’ Stealth vibration isolation roof curb incorporates adjustable spring isolators and a roof curb into a single unit. To adjust for weight and center of gravity, the isolators are custom sized and spaced to achieve a minimum 90 percent isolation efficiency. The curb’s formed steel counterflashing provides a weather seal with easy access to the spring isolators for adjustment or replacement. Factory assembled in five to seven working days and shipped in one piece, it features a 2-inch by 6-inch treated wood nailer for attaching roofing felts. With a standard height of 21 inches, the curb can be fabricated to match height and roof pitch requirements. For more information, call 214-221-5020 or visit www.tecometal.com.

Kinetics Noise Control KSR isolation roof curb rails are designed and engineered to isolate packaged rooftop equipment from the roof structure. They feature accessible springs and are easily installed with minimum interference from equipment overhang.

Their positive elastomeric air and weather seal permits the inside of the unit to be used as a return air plenum. The curb rails are available with aluminum weather seal flashing, seismic restraint, an airborne noise control package and duct block-offs.
