Reducing noise at its source is the most desirable approach to noise control. A sheet metal or plywood enclosure lined with an acoustic composite is a cost effective way to solve industrial and OEM noise problems. AcoustiGuard BTMM -14C and BV-14C are versatile composites that can be incorporated into a wide variety of enclosure applications.

BTMM-14C

Metallized mylar facing provides high contamination resistance and light reflectivity. It is suitable for very dirty, wet or oily environments and can be exposed to direct spray.

BV-14C

Perforated vinyl cover enhances acoustic properties resulting in superior absorption. Suitable for moderately dirty environments where it is not exposed to contaminants such as direct oil or water spray.

HIGH PERFORMANCE 20 to 40 dBA Reductions

The use of AcousticGuard composites in enclosures can reduce noise levels anywhere from 20 to 40 dBA. Careful preparation of all openings, seals and joints will eliminate noise leakage paths and maintain maximum performance.

COMPOSITE CROSS SECTION

1. Protective Cover Metallized Mylar Film - BTMM-14C or Perforated   Vinyl Cover - BV-14C faces in towards the noise source and protects   the absorption layer from contamination.

2. 1.0 in. Acoustic Foam absorbs noise and prevents is from reflecting out of the enclosure.

3. 1.6 lb/sq.ft. Barrier Layer provides transmission loss, keeping the sound within the enclosure.

4. 0.25 in. Foam Decoupler enhances the performance of the barrier - glued directly to the inside of the enclosure.
