VIBRO BARRIER ACOUSTIC BARRIER

VIBRO Barrier is a high-performance, mass-loaded flexible acoustic barrier engineered for superior sound isolation. Designed to minimize noise breakout from pipes, valves, fan housings, and ductwork, it is ideal for both pipe and duct lagging applications across commercial, industrial, and residential environments. Also known as a Mass Loaded Vinyl (MLV) Barrier, this limp-mass material effectively blocks unwanted noise and reduces sound transmission without compromising space. It is purpose-built to meet the acoustic demands of domestic, commercial, industrial, and automotive sectors. The dense core mass layer reflects and absorbs sound transmission through walls, ceilings, and floors particularly effective against critical frequencies generated by mechanical equipment, engines, and electronic audio systems. Prevents resonance issues commonly associated with thin, rigid materials, ensuring consistent acoustic performance. The foil-faced variant enhances fire-retardant properties, making it suitable for applications with elevated safety requirements. Easily cut and fabricated around pipe penetrations, ducting, and cabling. Its high tensile strength and tear resistance allow for long vertical installations, even in space-constrained environments.

VIBRO BASE INERTIA VRCB

When paired with appropriate VIBRO ISOLATORS, they deliver superior performance in equipment isolation, structural support, secure anchorage, and effective control of vibration amplitude. These frames feature a distinctive structural configuration that combines perimeter channels, isolator mounting brackets, reinforcing steel rods, anchor bolts, and concrete fill into a unified load transfer system. This design strategically employs steel under tension and concrete under compression, achieving exceptional strength and rigidity with minimal steel usage. Inertia bases constructed with VIBRO BASE frames demonstrate greater stiffness and durability compared to conventional designs that rely on heavier steel components.

VIBRO CLIP RESILIENT SOUND ISOLATION CLIP

VIBRO CLIP is a resilient sound isolation clip used to isolate acoustic floating wall & ceiling from main structure walls and ceilings. VIBRO CLIP creates a high STC (sound transmission classification) rating for your wall or ceiling assembly and offers an economical method to “float” your walls or ceilings. These isolation clips are used for vibration control of structure-borne noise and help build assemblies that will more effectively block airborne noise transmission To complete an envelope, secondary walls must be introduced with the same consideration given to mass and air gap as covered in the floor discussion. The best approach is resting these walls on the perimeter of the floating floor so the floor isolation system serves the walls as well. If this is not possible, the second choice is supporting the isolated wall on the structural slab with continuous rubber strip. With its durable design, ease of installation, and proven acoustic benefits, VIBRO CLIP provides an advanced, reliable, and cost-effective solution for modern soundproofing needs.

VIBRO CONNECTORS VRSF

VIBRO FLEX VBS

VIBRO FLEX Braided Stainless Steel Flexible Connectors are designed to effectively absorb and relieve stresses that occur due to piping misalignment, thermal expansion, or minor installation inaccuracies. Each connector consists of a corrugated stainless-steel tube that provides flexibility, while the surrounding stainless-steel wire braid offers reinforcement, strength, and pressure resistance. By combining these features, the connectors not only enhance the durability of the piping system but also help in reducing transmission of mechanical noise and vibration. This makes them highly effective when installed in systems connected to pumps, compressors, and other types of pulsating or rotating equipment, where vibration isolation and noise control are critical for maintaining system performance and extending equipment life.

VIBRO FLEX VSEJ

VIBRO FLEX St.Steel expansion joints are primarily designed to absorb dimensional changes in pipelines caused by thermal movement. They are made of bellows formed from thin-walled stainless-steel tubing. Compared to other methods of accommodating pipe movement, such as pipe loops or slip-type joints, bellows expansion joints are more efficient. Pipe loops occupy excessive space, while slip joints demand frequent maintenance. Moreover, both loops and slip joints can only accommodate movement along the pipe axis. In contrast, bellows expansion joints are compact, maintenance-free, and capable of absorbing multiple types of movement. VIBRO FLEX bellows expansion joints are offered with flanged, welded, grooved, or threaded ends. Internal liners are available to protect the bellows’ inner surface from erosion and to reduce vibrations caused by fluid flow. Additional options include tie rods for movement control and shrouds that shield the bellows from damage in buried installations. For proper anchoring and guiding of pipelines with expansion joints and to avoid joint extension or buckling due to pressure thrusts consult Akinco for expert guidance.

VIBRO HANGER NEOPRENE

VIBRO HANGER Model VCHN Vibration Isolation Hangers are specifically engineered to effectively mitigate the transmission of vibration and structure-borne noise generated by suspended light mechanical systems, including piping networks, ductwork, and associated equipment. These hangers play a critical role in maintaining acoustic comfort and structural integrity by isolating dynamic loads and preventing vibration propagation through building elements. Each Model VCHN Hanger integrates a color-coded elastomer insert operating in shear, paired with a high-strength steel load washer, all securely assembled into a precision-formed or welded steel hanger bracket. The use of elastomer in a shear-loaded configuration, rather than the conventional compression mode, provides significant technical advantages. Shear loading increases the permissible deflection range of the elastomer, thereby enhancing strain capacity while simultaneously minimizing material fatigue and long-term degradation. This results in improved service life and consistent vibration isolation performance over extended operational periods. The color-coded elastomer system ensures accurate load identification and selection, allowing engineers to match hanger capacity to the specific weight and vibration characteristics of the suspended system. Furthermore, the combination of stamped or welded steel bracket construction ensures both mechanical robustness and flexibility of application across a wide range of installation environments. From a cost-performance perspective, the VCHN Hanger represents a highly economical vibration control solution. Its optimized elastomer utilization, reduced wear rate, and simplified installation requirements contribute to lower lifecycle costs while delivering superior vibration attenuation compared to traditional compression-based isolation hangers. In summary, the Model VCHN Hangers embody a unique and efficient application of elastomeric technology in vibration isolation systems—providing durability, reliability, and acoustic performance in HVAC, piping, and ductwork installations.
