ACOUSTIC BLANKET SOLUTIONS

ACOUSTIC SHIELDS & BLANKET INSULATION FOR SOUND ATTENUATION

Acoustic Blanket Solutions are pre-engineered thermal acoustical insulation systems designed to reduce harmful noise levels and improve the surrounding work environment.

Custom-fit, through CAD technology allowing versatility in equipment coverage. Virtually any irregular surface can be insulated and multipiece designs are typical for most equipment applications.

Top quality design construction. The recommended design LT450A-TT features an inner and outer chemical resistant Teflon® fiberglass cloth, with high density fiberglass mat and barium sulfate loaded vinyl.

Removable and reusable. Removable acoustic insulation blanket pieces can be installed with minimal effort and fastened with a stainless steel wiretwist, metal spring tensioner, or metal D-ring strap with Velcro® tab. Installation requires no tools or materials.

TEST RESULTS FOR ACOUSTIC BLANKETS

With the following measured in the A-Weighting, the total noise reduction from the 107 dBA loudspeaker level over a 100-5000 Hz frequency band would be: 20.8 dBA for design LT450A-TT-1″ Thickness and 29.5 dBA for design LT450ATT- 2″ Thickness.

This data represent (ASTM) Test Procedure E-1222-87 for the laboratory measurement of the insertion loss of pipe lagging systems. Shannon will not be warranted for performance results of Blanket Insulation expressed or implied.
