Vibration Control and Isolation requires the use of various methods and materials to interrupt the movement of a structural sound wave. These products may be made of rubber, neoprene and other compounds or may contain mechanical methods of isolation. Applying metal damping products like Antivibe® or Vibstop will keep metal machinery or housings from ringing from impact of vibrations. Using combinations of the below materials will help break the transmission of sound through the structure or other solid material.

Floor Underlayments

Iso-Step® Floor UnderlaymentFloor underlayments are installed underneath finished floor systems to reduce impact noise, footfall and the physical transmission of sound. Acoustic floor underlayments help structurally isolate the top finish layer from the rest of the components. These types of assemblies are commonly known as a ‘floating floor.’  This essentially ‘short circuits’ the sound and breaks the connection between materials in the completed assembly. Our Iso-Step® Floor Underlayment is manufactured from recycled rubber and may be used in a wide range of flooring assemblies. Rubber is a resilient material that absorbs and disperses impact energy very well. For use in gypcrete and other concrete flooring applications, the Enkasonic® Floor Underlayment is the popular choice. The mesh mat creates an airspace with minimal surface contact to the underlying subfloor. Both of these materials are installed under flooring finishes to generate a higher IIC (Impact Insulation Class) rating for a construction assembly.

 

Machine Mounts and Hangers

Vibration control for machinery typically requires isolation pads, mounts, washer bushings, and hangers to short circuit sound at their contact points. Consisting of high-grade neoprene, prevent sound from transmitting to the floor from machinery legs by placing our AlphaIsolation™ Cup Mount or attaching the Mason Industries Isolation Mount underneath. Vibration Isolation Pads can be place under machinery to do not have specific leg mounts. Mason Industries Isolation Washer Bushings are useful when installing isolation pads and when creating other assemblies. To isolate items that hang from the ceiling like grid systems, pipes, duct work, look to the Mason Industries Isolation Mount.

Room Isolation

When creating wall, floor and ceiling assemblies, various methods of attachment may be deployed to reduce sound transmission. Studs and floor joists may be friction fit using our Stud Isolator. Resilient Sound Isolation Clip (RSIC-1) and the Green Glue Whisper™ Clip install in conjunction with a resilient channel to isolate the initial wall layer from the underlying structure of the building. Once a single layer of drywall has been installed, to isolate subsequent layers of drywall use Green Glue Damping Compound between the layers. 

Metal Damping

Manufacturing lines, conveyors, bins, chutes, hoppers or other types of metal panels require vibration control by damping. Lightweight metal parts or housings are subject to sympathetic vibrations or ringing. This generates noise that is either irritating or may not pass safety or noise regulations.  Antivibe® DL-10 Metal Damping Compound applies direct to the metal ringing surface either by spraying or troweling the compound. If you want a completely DIY material, our VibStop Vibration Damping Sheet is a self-sticking rubber sheet that is simply ‘Peel-and-Stick’.
