Technical Data Sheet

STC (Sound Transmission Class), is a numerical rating of how effective a material is at blocking the transmission of sound through itself. This rating generally applies to hard materials like rubberized sound barriers, concrete, brick and drywall but also applies to a much lesser degree to softer materials like mineral fiber (although it isn’t tested by itself; it’s tested as part of a wall system to verify its effectiveness).

Step 3: Mark & Resize the Acoustic Foam To Best Fit

Measure the designated areas that need to be field cut on the foam and make the appropriate cuts (examples would be around beams, doorways, or if a short piece is needed). After all the pieces have been field cut, put the material back in the appropriate position on the wall or ceiling and lightly mark the bottom and side of where each piece will be lightly with a pencil to ensure straight application.

Step 4: Apply Arrowzoom Tape or Glue the Acoustic Foam with Adhesive Spray

There are two ways to put the acoustic foams on the designated wall.

Method 1: Use Arrowzoom Sticky Double Sided Tape. Each foam should use 4 tapes. One for each corner. Once you peel off the sticker, the Acoustic Foams should easily sticky to the surface of your choice.

Method 2: Glue each piece individually with PL Polyurethane Construction Adhesive. Create a perimeter around the outside of the material staying 1 1/2" away from the edge. Create an X pattern across the center of the material.

(Note: Due to Shipping Reason, we do not sell Glue)

Step 5: Hang the Acoustic Foam With The Marked Line

Line up the materials on marked lines from Step 3 and press firmly against the material compressing the foam. Repeat step for remaining pieces of foam.
