Sound Seal's Industrial Acoustical Curtain Enclosures
are available as complete, partial, or portable enclosures. Industrial sound enclosure
options include sliding door panels, view windows, strip doors, air intake and
exhaust ventilation baffles, partial or full roof panel systems, and corner strips
among many others. Industrial sound proofing enclosures and sound proofing screens
are available in models BBC or
BSC composites panels and may be supported from our standard track and hardware
systems or our heavy duty structural steel systems. 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
