Acousti-Composite is a noise control material specifically
designed to achieve maximum attenuation over a broad
frequency range. Acousti-Composite combines dense, limp,
flexible, non-lead loaded barriers with Acousti-Foams
providing a total noise control system. Unlike other
composites available, these multilayer systems are
manufactured without costly adhesives, thus eliminating the
potential for failure between layers.
Designed by acoustical engineers, Acousti-Composite has been
optimized to economically provide:
High Transmission Loss - the barrier's ability to
impede airborne noise.
High Noise Reduction Coefficients - the foam's
ability to absorb airborne sound energy with minimum
reflections.
Damping - the composite's ability to attenuate
structure-borne vibration on metals and plastics.
Thereby reducing reradiated noise and material fatigue.
The diversity of constructions makes possible engineered
solutions for most OEM and in-plant applications. Acousti-Composite
is available with single and double layer septums, various
barrier weights, foam thicknesses and a variety of surface
treatments.
Composite is available in rolls, sheets, die cut or
fabricated to customer specifications or can be easily field
cut with a knife or scissors. These composites can be
adhered to the substrate with factory supplied, economical,
SBR pressure sensitive adhesive or an acrylic based pressure
sensitive adhesive for temperatures up to 250°F.
It is recommended that a contact adhesive or mechanical
fasteners be used for these heavily loaded composites in
overhead applications.
Acoustic Foams - Melamine Foam
Melamine is a lightweight, high temperature resistant, open
cell foam manufactured from melamine resin. It combines
excellent thermal properties with superior sound absorption
capabilities to create a versatile fiber free product which can
be applied in situations which may prohibit the use of urethane
foams or fiberglass insulations. This fire retardant foam meets
the flame spread, smoke density and fuel contribution
requirements necessary to comply with Class-l building code
regulations. The high performance thermal and acoustical
characteristics of this flexible, low density foam make it an
ideal product for in-plant and FDA approved applications.
In addition to being the solution to aircraft and architectural
noise problems, Acousti-Foam Melamine Foam is the material to
use in OEM products requiring a combination of thermal and
acoustical insulation capabilities. Optional facings can be
applied for more durability and chemical resistance as well as
pressure sensitive adhesive for ease of installation.

Many applications require these products to be subjected to
environments such as dirt, moisture, chemicals, and abrasion
that could be hostile to an unprotected foam. IES-2000 has developed various surface treatments to protect the
integrity of the foam from these elements. These facings will
increase the absorption properties at certain frequencies as
well as provide a cleanable, decorative and durable finish for a
wide variety of applications.

Acoustic Foams - Polyurethane Foam
Acousti-Foam acoustical foams are designed to provide
maximum absorption of airborne sound with minimum thickness
and weight. These flexible polyurethane open cell foam
products are manufactured to optimize pore size, air flow
resistance, and density.
Sound energy, passing through the cell structure, is
converted into minute quantities of low grade heat that is
easily dissipated. Since the uniformity of the cells are
carefully controlled the efficiency is constant and
predictable from one installation to another. Many
applications require these products to be subjected to
environments such as dirt, moisture, chemicals, and abrasion
that could be hostile to an unprotected foam. IES-2000, Inc.
has developed various surface treatments to protect the
integrity of the foam from these elements. These facings
will increase the absorption properties at certain
frequencies as well as provide a cleanable, decorative and
durable finish for a wide variety of applications.
Acousti-Foams can be purchased in rolls or sheets, and
can be die cut, or fabricated to customer specifications.
They are easily cut with a knife, saw or scissors. The
addition of pressure sensitive adhesive provides a
convenient method of fastening to most substrates
