Model 3 Road Noise

The product page says it doesn't hold water, but maybe @enemji can test it a piece in the tub and find out?

Will do and let you know. But I will tell you it is slick. It is Plastic/Rubber foam. Additionally I am not even sticking it. It it is vertically placed so everything just slides off.

and as expected the water just beads away

@enemji my roll is on order! Thank you so much for all the work you’ve shared with us.

Note: The 4mm roll has an adhesive back covered with paper. Because I did not want the paper to be part of the solution (gets wet, etc), I took off the paper and folded the foam on itself ie stuck itself using it's own adhesive. This actually benefited from doubling the insulation.

Gonna buy 1 roll, where do you think I should stick/put the rest of the roll other than in front of the front doors for the most effective results?

The trunk well. If not, you will see an imbalance in the road noise. The front will be quieter than the rear seats.

How is the material staying in place with the door opening and closing frequently?

Stays there as it is a press fit and the doors actually pushes it back if it even tries to come out

It is a press fit as you can see here

I bought this which is cheaper and just the right size to cover both sides. I will try to put it over the weekend. The biggest problem seems to be making it the correct size, since the whole area is obscured by the door and difficult to measure.

But it is thicker. You may definitely have a hard time getting it in there.

I won't double fold mine like OP, so it should still work. I will report the results here....

Would you be sticking it to the panel? I would be interested in seeing how well a mat whose intended use it to add weight and stop vibrations performs as a sound transmission blocker. In this case we are attempting to block the sound created by the tires from traveling across. Keep us posted.

OK so here is what I did: I first roughly cut some packing paper to a little larger size and pushed it into the opening to take the imprinted shape of that space, I marked the edges with a pen, then took it out and cut with scissors, creating a paper template, which I used to cut the mat to size. If I then just put it in there, it stays, but it's not stable and tends to move around after the door opens a few times. I then removed the adhesive cover and tried to attach it that way, but it is hard, since it can't be put cleanly over the spot, it has to slide into place, and with the adhesive it's impossible. I had to cut it into several sections to make it doable, and it's still not perfect. I will just redo it more carefully later, but for now I will drive around like this to see if it makes a difference.

Cut it couple of millimeters oversize making it a snug fit. This will hold it in place. That is how I did it.

Do report back! Also, does your foam cover/block the panel gap at the bottom of the A pillar area?

that is where the PE foam is more manageable as it folds and springs back to the shape and gets a snug fit.

enemji was there a reason you folded it over on itself instead of just putting the adhesive down with a single layer? I got my roll in today and am about to start the project.

 

[galimpic]

I actually chickened out and after some 30 mins went back to the car and removed the whole thing, as it was not put in place to my satisfaction and I was afraid that it would become sticky and impossible to cleanly remove later. I will try to do it differently.

That's the new plan!

I tried to, but the area is not flat there so it's tricky. I will certainly try with the new cut.

Yeah, this one is easily bent and won't stay in place by itself. However the important thing is to deaden the sound, and this one looks like it would do a good job in that respect.
