Industrial Acoustics Company's Moduline® System
features modular Noishield® and Noise-Lock®
components with high sound-transmission-loss and sound-absorption
ratings providing excellent noise reduction characteristics.
Components include wall, roof, and floor panels, doors,
windows, ventilation units end silencers, panel joiners,
trim and hardware; all part of an acoustically and structurally
rated "building block" system for a multitude
of applications.

Roll formed from a single length of steel,
the IAC H-Joiner is strong enough to give
Moduline® structures loading strength
of more than 50 psf (2394 N/m2), which permits
roof storage and provides high wind load
resistance.

Fire-Noise-Lock Panels are shipped with UL
labels certifying 1-hour (solid side) and 1.5-hour
(absorptive side) ratings. Doors are certified
and shipped with 1-hour, 1.5-hour or 3-hour
rating as required. Trackwall® available
with 1.5-hour rating. Ask for Data Sheet MDS
1113 for further details.
Moduline Structures and Components can be designed
to withstand 1 psi (6895 N/m2) blast
load. All doors remain operable after blast.
Moduline Noise-Lock Acoustic/Ballistic Panels
are Underwriters Laboratory listed for bullet
resistance in accordance with UL Standard 752.
System is rated for High Power Rifle (HPR),
Super Power Small Arms (SPSA), High Power Small
Arms (HPSA), and Medium Power Small Arms (MPSA)
Moduline Structures qualify in many applications
for tax savings associated with accelerated
depreciation. Other construction components
such as dry wall or concrete block do not qualify.
Savings with Moduline can amount to 25% of purchase
price. Industrial Acoustics Company recommends
consultation with tax or financial advisors
on the specifics of each application. Ask for
Moduline Data Sheet, MDS 1020 for further details.
Each Moduline Component is fully described
in over 50 detailed engineering and application
data sheets which make up a new expanded edition
of the Moduline Application' Manual. It provides
engineering data including sound transmission
loss, sound absorption, sizes, weights, materials
of construction, and application information
utilized in the design and installation of noise-control
structures. Request IAC Moduline Application
Manual Bulletin 6.0502.
Since 1949 Industrial Acoustics Company has
pioneered exclusively in noise-control products
and systems for industry, architecture, research,
aerospace, power generation, and air conditioning.
IAC possesses a unique reservoir of practical
noise-control engineering know-how as applied
in thousands of installations. IAC will be pleased
to make recommendations to meet any acoustical
criteria and requirement. For unusual problems
let IAC's engineers and research facilities
go to work for you.
