  • Fire Resistance Ratings

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.

  • Blast Resistance

Moduline Structures and Components can be designed to withstand 1 psi (6895 N/m2) blast load. All doors remain operable after blast.

  • Bullet Resistance

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)

  • Tax Advantages Reduce Cost

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.

  • Detailed Moduline Application Manual

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.

  • Unequaled Engineering and Manufacturing Organizations

Since 1949 Industrial Acoustics Company has pioneered exclusively in noise-control products and systems for industry, architecture, research, aerospace, power generation, and air conditioning.
