Soundproofing under carpet?

[Mambeaux]

Beings that we are not going to Miami this weekend we decided to spend that money on new carpet for the boat. Does anyone have a line on the marine sound insulation to go under the carpet?

Soundown caprpet underlayment http://www.soundown.com/AI.htm. Great products and great company to deal with

You might consider mass loaded vinyl as a sound blocker. The soundown underlay is good but it's more of an absorber than a blocker so if your above the noise (upper deck) this might be better http://www.acoustiblok.com/

Call Steve or some of the guys at Sams Marine they have some sound deading material on sale right now.

We are just getting ready to carpet the salon and master and VIP staterooms. In doing a search, I see that some of you have used something called acoustiblok and someone else used some other type of sound deadening underlayment under the carpet. One post also said that Sam's has some material for this. Does everyone do this or do most just use a good pad? It is noisy right now but will probably be getting a sound shield for generator soon. What kind of price are we looking at and can a regular carpet person work with this stuff? We have a '72 53MY.

Do you think this is overkill or do many people do it?

It can make a big difference.

Sound proofing is always a multi point attack. Most of the noise in our boats is structure born vibration that radiates thru the structure. Acoustic carpet liner or mass loaded vinyl will probably do very little if they are all that is done.

today i'm replacing the carpet on the 70 footer i run and found sound insulation under the saloon carpet (above the ER)

it's a black foam, about 5mm thick, glued on to some heavy rubber about 1.5mm thick. the foam is kind of like hatch seal material, very dense, is face down on the floor. no markings or manufacturer info on it.

pretty heavy and effective...

Hi All,

We recently replaced the entire carpet in our 1974 48 Yachtfish. Assuming the trade of carpeting is just carpeting really made an ass out of me. Just fyi the carpet has a noise reduction pad under it that make a tremendous difference. It was there when we bought the boat and we had new regular carpet pad put over it.

1. I went with commercial grade carpet (not a bad choice but really limited my selection)

2. I assumed if they could carpet a house they could carpet a boat. Wrong again. Everywhere in the boat that resembled a house ie staterooms and hallways and closets look great, the engine hatches were a horse of a very different color. When the job was completed they had bound around the hatches and bound around the hatch covers, the two shall never meet and it left a gap around the hatch covers for noise and dust and dirt etc to come through.

I haggled with the guy, threatened not to pay the balance yatta yatta you all know the routine. In the end I had them make me three bound pads (out of the new rug) to completely cover the salon area (engines are directly below). They actually enhanced the noise reduction aspect and thankfully look well.

3. Don't be a pushover like me. Insist they redo the job correctly if there's a problem.

4. Be sure you tell them up front that if they scratch the teak taking the carpet out or installing the new one you will not pay them their whole fee. The first carpet guy began to rip the carpet out and scratched the recently varnished teak with the carpet staples (way below the surface) and he couldn't understand why I was upset (idiot). I threw him off the boat hat in hand.

5. Use resources to locate specific folks with knowledge in marine applications. Both of the installers i used came very highly regarded but had never done a boat, and I didn't ask, which makes me an ass again.
