Floor Insulation

Anyone have any ideas or suggestions about how to insulate the floor of my TJ? I am getting a ton of heat up through it after I have driven around a little bit. I noticed there is a strip of insulation under the jeep , above the muffler, but I am wondering if anyone knows of something that might go under the carpet?

thicker carpet, or an additional layer of carpet padding...you may be fighting an uphill battle.

I find it strange that you're having this issue with carpet installed...

Mine gets very hot also. I plan to replace the carpet soon, and will likely use either brush-in bedliner, reflectrix insulation, or both.

If you guys have manual transmission check your shift boots for tears...sounds silly but that made a difference on my 01...Mine was in two pieces.

Oh that's another idea, Rhino line or similar then put the carpet back.

A small body lift could help. Idk for sure but it's a thought anyhow.

It doesn't and neither does the rhino lining. It sounds like the op currently has carpet. If so pull the carpet out and drive a few days without it. When you put the carpet back in it will be a huge improvement. I have heard bedrug has better insulation than factory but have no personal experience with it.

I used HushMat sold by Summit Racing, it is used for sound but also great thermal insulation and reduces engine heat on the trans hump. Two sheets 12.1x23'' peel and stick application.

I wrapped my exhaust with heatwrap from the collector back to the rear axle and built a heat shield for my muffler. I also have my header wrapped, and since i run without carpet i put 3 heavy coats of bedliner on the interior of my tub and with my molded floor mats in I ca drive around all day in flip flops with no problems. Even in the summer with the hardtop on and no a/c its not bad.

Get a new shift boot that bolts to the floorboard. Also, I bought some light insulation from Lowe's. It came in a roll, metallic looking. it was very inexpensive. I put the insulation next to the floorboard under the carpet. No more heat issues for me.

Adding insulation, thicker carpet, etc., is fine but depending on how you use your Jeep, could become a problem if it gets wet. Aside from the eventual smell, it could cause rust problems. And, taking it out to dry it could become a PITA too.

I would be concerned that it gets so hot. I have no carpet and dont notice the heat other than the trans hump, which is only noticeable if I touch it.
