Soundown Barrier Composite Insulation is the most commonly used material due to its wide range of applications and excellent acoustic properties. These composites are typically a fire retardant polyether foam absorber and decoupler type, with a mass loaded PVC barrier in one of several different weights. They also have a rip stop Mylar vapor barrier. Other absorber and decoupler materials include several types of fiberglass, mineral wool, and polyimide foam. Lead barrier is also available. Barrier composite materials are available in 1/2 - 4" thicknesses, depending upon the material configuration.

Soundown Acoustic Carpet Underlay is a composite material using Soundown Tuff-Mass® as a barrier in weights of 1 or 2 lb., and acoustic foam decoupler. There is an option for a soft or firm acoustic foam layer that provides a comfortable feel. Soundown Carpet Underlay reduces noise radiating from carpeted surfaces. It may be used alone or to supplement insulation applied in engine spaces. Soundown Carpet Underlay is manufactured in 54" width at 1/4" and 1/2" thickness.

Soundown Acoustic Absorption Materials are used in applications where barrier treatments are not required. These treatments are manufactured from a wide range of base materials such as polyether foam, acoustic fiberglass, coast guard approved fiberglass, polyimide foam, and mineral wool. Soundown Acoustic Head and Hull liners also provide good absorption performance in occupied spaces. This family of products is delivered in various sizes and configurations ranging from 1/4 - 4" depending on the material specification.

Soundown LCF Polyimide Foam is an engineered flexible foam insulation for acoustical and thermal applications. The extreme light weight and highly fire resistant nature of Polyimide foam makes it ideal for a range of applications. As a flexible foam product Soundown LCF can be installed far more easily than fibrous board alternatives such as fiberglass and mineral wool.

Soundown’s Quilted 2” x 1lb/ft 2 Pipe and Duct Wrap is a composite material manufactured and sold as 4’ x 25’ rolls. This product features a flexible 1lb/ft 2 mass loaded vinyl with a reinforced mylar protective finish. Typical uses of this product are to wrap noisy pipes, ducts, valves and fan housings.

  • Standard roll size is 4’ x 25’
  • Accepts Soundown Mylar Tape, 2” -6” wide for easy installs (parts HTA20SC, 40 & 60)
  • Class A (or 1) flammability rating per ASTM E-84

Use Quilted 2” x 1lb/ft 2 Pipe and Duct Wrap to wrap noisy pipes and ducts to prevent break through noise from transmitting through the wall of the pipe or duct. The use of the 2” fiberglass creates a decoupling effect, which yields increased low frequency attenuation. The 2” thick quilted fiberglass absorber also provides improved thermal insulation around the pipe or ductwork.

Product Data:
