Has anyone ever installed dynamat and 1/4” dynaliner on the interior floor of there car? If so, did you have any issues or problems with thickness? I was planning on covering the entire floor and hump. I thought I’d ask before I got started. It’s an automatic console car.
 
I installed dynamat extreme and some 1/4" closed-cell foam and on top of that I also got the insulation-backed carpet. I probably overdid it. No issues for me, but I don't have a console.

Keep in mind Dynamat is designed for sound deadening, not insulation. You don't need 100% coverage for it to be effective, especially if you use a foam insulation. Reason I mention this is if you think you're going to have spots where you want less thickness, you don't have to install Dynamat there.
 
Have you heard the stories of people using the tar roof adhesive on cars. They have a definite aroma when the temperature starts increasing.
 
The Dynamat is pretty thin and didn’t think that would be problem but adding the 1/4”dynaliner might be.
 
bought X mat from East wood. After much research it seemed to be the best. The foil will cut you if not care full. LOL. Got the roof liner made for roof and hood application's. No problem with covering the tunnel. Every thing fit fine with the console. I was afraid of the thickness also. But left it off where the floor shifter came through. So the boot would seat well.

Drove the car yesterday and it is quiet.

That's a good point. Some are tar-based, some are butyl-based. The butyl ones have no scent. The tar ones also may not adhere as well in high heat areas.
 
I used this instead of dynamat. About 1/2 the price. No smell. Then used this insulation over it and then the carpet.

The X mat has no smell. Think it is butyl also. It sticks well. No issue with fitting console after installing carpet. That was my biggest concern was it going to inter fear with fitment.
 
I installed dynomat and used adhesive duct insulation inside the doors and quarters. I had more than enough dynomat covering more of the floor than planned; figured that was enough...being a vert I can hear more of the wind noise from the top, lol.

I have Dynamat on my 31" coupe and even on such a same car it gets stupid expensive if you do everywhere. I used a product called Siless that i got from Amazon and it is the same stuff but way easier on the wallet.
 
I used Dynamat on the floors then a layer of 1/2” jute padding. No problems, quiet and cool.
 
I need to tear Fred apart and put something down on the floors because of the big heat eminating
from the headers and 3" duals underneath; it turns the interior into a bit of an oven in summer.
Forget sound, which of these are good at standing up to and holding back heat?

For the interior, closed-cell foam is your best bet. Get something that isn't bubble-wrap style, because that will collapse once compressed.

I used this stuff, they have a thicker version as well. It should go over dynamat if you use that.

Comes in self-adhesive rectangles, easy to work with and contours pretty well. The adhesive is pretty strong, so try to make sure you have it cut to size and in the right spot before you stick it down.

There are also types that are made from recycled denim, but it seems like those would hold water and cause problems.

If it's primarily heat from the exhaust, heat wrapping the collectors and exhaust under the passenger compartment will do the most good and is not that expensive. Some reflective tape on the underside of the body near the exhaust works well too.

Interesting timing for this subject to pop up.

Wife and I were just talking last nite to add some kind of heat blocker material to the floors of the car .
With high ambient temps it can get pretty warm inside , black car doesn't help I'm sure

Ive used FatMat rattle trap before. But that was more for sound deadening . Im thinking here the next few weeks pull the seats and carpet and do it in this car. But ,,, I would like to add some additional heat barrier as well
 
Just wonder if any one has installed those blank out's in the trunk. Like where it blocks the drop down area and the trunk from the front where the wheel well is. Looking into doing that would like to stop heat from traveling from the trunk to the passenger part of the car.

You don't know what heat is like until you've driven something like my A100 with the engine and headers only inches away from the driver seat. :lol:

I'm getting a special zip-up blanket cover made soon. :rolleyes:
 
I bought self adhesive butyl backed material from our Rona store, like Home Depot. Used in the heating and plumbing trade. About $80.00. US. Had some left over that I will put on the roof.
 
East wood has a special mat for roof and under hood. It will withstand the heat in the summer. I did my roof before putting the head liner in. But did not do the hood. Just ordered the fiber glass hood insulation. They sell the x mat.
