Insulating mats

[yuhaze]

Has anyone looked into these? I know the Genesis is insulated, but I figure this couldn't hurt at all

Looks like they are difficult to install.

If you took off all those panels dynamat may be a better product to use.

Well, I've done a little more research in the meantime, and there is quite a bit out there.
AS the genesis already has pretty good sound insulation, I merely wish to improve on an already good thing.
I would like to better understand what is already in the Genesis, and what the best product is to complement what is already there.
I understand there's deadening material (mass loading), and the there's insulating material, like closed cell foam.

Without really knowing what is already in the car, I'm thinking closed cell foam for an extra barrier (strategically placed) would work best.

I wonder if the service manual describes how the Genesis is insulated.

My review of the service CD manual did not disclose where/how the Genesis is insulated. I think the Genesis is well insulated from the factory, but it can be improved. The extent of any factory sound insulation is dictated by cost, ease of installation and time to install. Dynamat makes excellent products, but they are not cheap. I have successfully used a comparatively cheap product that is designed to repair home rain gutters. It is available at Lowes for about $1.10/sq. ft. It is self sticking butyl rubber "tape" with an aluminomized coating on one side. I have installations on trunk lids that are over five years old that are holding up well. But, there has been some criticism of butyl rubber sound insulation holding up in very hot climates.
I have done a first stage - which was done by removing the rear seat and covering the entire area with this tape. It made a difference, but it was not dramatic.
My biggest noise complaint is tire noise, which is very bad here in Oregon where studded tires have ruined pavement. I think my next step will be to insulate the inner fenders.

Looks like you did enough research regarding the sound deadening materials.
The mass loading material is best used to kill the vibration of a hard material like sheet metals, and use the closed cell foam type barriers to insulate.

Some say that covering aprox. 30% of the sheet metal with the mass loading material is enough and that covering the whole thing with 2~3 layers of those is overkill.
I agree to some extent and think that one can get better results by using both materials.


I have removed the door panels to eliminate some annoying rattles from the door and noticed that the Genesis has decent sound insulating material inside.
It's not nice as the closed cell foams we see online, but it sure is beefy enough to cover most of the road noise, IMO.
I added some Dynamat onto inner door sheet metal and it did eliminate most of the rattle noise that's audible when playing loud music.

I've seen those insulating mats you posted and thought it was a neat product.
Of course it wouldn't hurt to add those, but the price is too steep for just an experiment. And I think it won't help that much.

Let us know if you decide to try those.

Here is what I think I'll look into for now:
I want to examine the trunk space and see what is under the battery/spare tire. I'll put some sound deadening material in there, but only cover the flat surfaces - no bends or anything like that.
America mat looks like a good closed cell foam to maybe put in other places as a barrier. I'll post more detail as I develop my plan.

Adding dynamat seems to be very hard, you have to remove all the carpets and seats to do that, im thinking of doing that under the car, i mean adding dynamat from below, it will be much easier and no need to remove interior stuff!
