db Engineering flexible noise barrier materials are limp and tough.  They are resistant to the passage of sound waves and reduce noise transmission.

dB Engineering Flexible Noise Barriers are available in a number of styles to meet a variety of applications.  For example, the non-reinforced barriers can be used to reduce noise between rooms when incorporated in standard wall or ceiling construction.  Reinforced barrier materials are used where high-strength, high tear-resistant materials are required.  The foil-faced lagging material is used to wrap noisy piping and duct work (see dB-105).  Additional high-temperature and other specialty barriers are available including a Class A Flammability rated barrier.

accoustical data for Flexible Noise Barriers

Barricade Noise Barrier is perfect for applications that require high sound transmission classification (STC).  Barricade Noise Barrier is a mass loaded flexible noise barrier that reduces sound transmission through walls, floors and ceilings

APPLICATIONS

Barricade Noise Barriers are ideal for hotels, classrooms, homes, home theaters and any areas where reduction of noise transmission is necessary.   Barricade Noise Barrier is available in rolls 54" wide by 60' long.

CONSTRUCTION

Barricade Noise Barrier may be installed in conventional wall construction or in a staggered stud assemble for higher STC results.

ADVANTAGES
Barricade Noise Barrier is easily installed on walls, floors and ceilings.   Complicated construction is unnecessary.  Low cost solution for noise transmission problems.

AVAILABILITY
Barricade Noise Barrier is available in rolls 54" x 60' long, 270 sq. ft. per roll, with custom lengths available.
