Acoustic Barrier Composites Insulation
Soundown offers a range of barrier composite insulation materials that increase the transmission loss of panels or walls. These composites feature a mass barrier floated in a composite of foam, fiberglass, or mineral wool and finished with a range of durable vapor barrier facings.
 Soundown’s Vinyl/Foam composite insulation (IVF) is designed to reduce airborne noise that radiates from engines, and other machinery. The standard composite consists of a layer of TuffMass loaded vinyl sandwiched between two layers of fire retardant, polyether foam and protected by a vapor barrier facing. Soundown composites are produced specifically for attenuation of sounds from machines such as engines, generators, pumps, and other equipment which may have significant base and mid-range frequency components. Our standard construction centers the acoustic vinyl between equal thicknesses of foam, front and back to optimizes the mid and bass frequency sound isolation. Where high frequency noises are of concern Soundown can fabricate specialized composites.
 Soundown’s QuietLag, acoustic pipe and duct wrap material consists of a fiberglass decoupling layer and TuffMass barrier with reinforced facing. This product is used in wrapping of pipe and ducts to reduce breakthrough noise from the fluid, gas or media travelling through the system. Common applications include plumbing, HVAC, and material handling systems.

Soundown offers the highest quality acoustical foam products available today. Our Acoustic Absorption Foam is an open cell acoustical grade polyether designed to have excellent acoustic properties. Our Acoustic Foam is available as thick as 3” with options for a number of different facings as well as pressure sensitive adhesive. 
Soundown TuffMass is a specially developed mass layer product offering superior acoustic transmission loss combined with good vibration damping properties. TuffMass is available in surface densities from 0.5lb/ft2 to 2lb/ft2. TuffMass offers STC ratings as high as 33.
This an extensional damping sheet based on out formulation for Mil PRF 63563D Type II that is ideal for achieving critical damping on steel and aluminum structures. This product is available in thicknesses of 1/16”, 1/8” and ¼” as a sheet material or as 3/8” and 5/8” thick tiles for use on substrates of varying gauge.
Ecodamp is a highly flexible self adhesive damping compound with a light constraining aluminum cover. These materials can be used for applications on light panels or pipes to reduce ringing and breakthrough noise. 
Soundown type BRB anti vibration mounts are easily installed mounts that utilized rubber in shear and compression. Their ratio of height to width is optimized for high deflections, low natural frequencies, and excellent vibration isolation results. 
The Soundown Ring/Bushing Kits are two component mounts that are used in conjunction with a hold down bolt for the effective isolation of equipment or panels. These mounts combine rubber stiffness and form factor to produce high deflections at light loadings.
