Great Look for Study Room ! Thanks Arrowzoom!

I've struggled with noise issue for a long time when I wanted a quite work room. Since my apartment is near the train station, I could always hear train coming by. Since Covid, I had to work from home. I could hardly concentrate with all the disturbance from outside. So I had decided to research a quick fix to resolve the train noise issue.

After researching, I found out that Arrowzoom sells great quality products with the color bundle that I like. Go Yellow! So I ordered 100 pieces yellow and 100 pieces of black along with some tapes. The foams came in compressed so my husband and I needed to lay them out and dampen it for about 24 hours. The entire living room was compiled with foam. The whole project took about 2 days. We couldn't be happier with the outlook and the sound blocking effect!

Love the Makeover with second floor

After researching on how to renovate my second floor. I decided to soundproof the room before turning it into my music studio. I ordered 100 pcs of gray and 100 pcs of blue along with 34 sets of 24 pcs of tape. The delivery was within two weeks, Somehow it was delivered into 2 parcels. The foam came in sealed. It took me 24 hours to decompress it. Luckily there was a tutorial video of showing how to decompress and install it.

The whole room took about 3 days in total to complete. 24 hours to depress, and two days to install. I am so excited about the finished result! Absolutely looking forward to putting my drum set and keyboard in here.

Well made product

Pictures can be manipulated, but when you have the product in your hand you can tell whether it is a cheap product or a well made product. This is a well made product.
Additionally it is a very responsive company to any issues....great customer service !
Would definitely buy from again.

Perfect for musicians

For my purposes which was to convert an existing closet in my music studio into a semi soundproof practice area, acoustic foam was the perfect choice. My wife cannot almost hear me practice in any part of the house. If she stands right outside my studio door it sounds like a TV or radio with the sound turned down low. Very happy with the output of my purchase.

Perfect and inexpensive

To install: I'm experienced with these products as I have a studio.
You DON'T have or need to apply any spray adhesive MUCH LESS on your WALL. To remove them, you'll destroy your wall, the paint plus the drywall coating will rip apart.

INSTEAD, use a Surtape brand double sided adhesive roll (see pictures) by applying the tape on a black cardboard (found in most department stores in the school supply session). It also does not need to be the exact size of the acoustic foam. Note that 2' of each foam on ↕️ orientation will stay a tad outside the cardboard foam area since the cardboard is not 2' tall which is no problem, and on the ↔️ orientation, in a sequence of 2 x 6 foams signed, you can cut the 3rd piece cardboard and tape them with each other to exactly 6' wide. BUT before you stick the foam on the tape, apply 5 dots of hot glue to all 4 sides of each foam plus 1 dot in the center. As soon as you apply the glue, you MUST bond the foam immediately! Otherwise it will cool off in seconds.

How Many Acoustic Foams & Soundproof Panels Do You Need?
