Insulate Floor of JK

When driving on the highway the floorboard didn’t get too hot; but when driving off road it got very warm, so I decided to insulate the floor of my JK.

I used 4 rolls of Thermo-Tec #14620 which is 60 square feet of material to insulate the floor of my 2008 Jeep Wrangler Unlimited Rubicon. This material appears to have very good specifications when compared to similar products.





Last year I insulated the inside of the hard top. Here is that write-up:
http://www.jeepforum.com/forum/f96/d...ardtop-809376/

Take the recovery gear, seats & carpet out of Jeep. Then clean the metal from all mud & stuff.



I measured then cut the insulation into small pieces for easy installation. I used small pieces about 6” & 12”. The stuff is easy to cut w/ razor blade tool. Then peal the backing on and stick it on the metal surface.





Then use a roller to smash the insulation onto the metal. Then cut out the seat & other holes in the insulation.







Then put the carpet back in. Notice the slight ridge in middle picture; that is where the front drive shaft broke and banged against the floor of the Jeep; but that is another story.







Total cost $200.00. I got this from Auto Barn. I don’t work for, nor get any remuneration from, Auto Barn or Thermo-Tec.

I tested this 3 weeks ago in Death Valley (only 92F – so not that good of a test); but it really helped keep the heat on the feet down to a manageable level.

An added bonus is that the Jeep is now very quiet, I can even hear the stock stereo while on the highway; even over the whine of the tires.

If you remember, report back this summer when the temp is around 110 degrees. Maybe Iíll do something similar like yours.
Nice right up too.

I love what you did and it looks great, but I never have any carpet in my Jeep, so it would end up looking like the inside of a space ship if I did that.

How much did it cut down on the road noise? Humming tires?

I think you may need to go back and cut holes over the floor drains. Just in case you need them in the future. Nice job there!

Very cool!

I am looking at doing not only the floor but the Inside of the Hard Top too... Last summer when it hit 117 It felt like I was riding in a Microwave oven even with the A/C on Full blast.

Love my Black Jeep but wow it gets toasty. I was even considering buying a Roof rack and painting the floor of the basket Silver. I'll Just leave it on all summer.

Thanks for all of the positive comments. I know a lot of Jeep folks take the doors & roof off to go wheeling. I wheel mostly in the deserts of the southwest and I like the doors & roof on with A/C running. Last year I did the insulated the roof and that helped a lot. Now, I'm hoping this floor insulation will continue to improve my wheeling comfort.

... I thought about cutting out around the drain holes; but in the 2 years I've had this beast, I haven't needed to drain the water out.

... Between the insulation on the roof and the floor, it is surprisingly quiet in my Jeep.

... "cool" ha ha - I hope so.

That is a really good looking job, but

I live in the desert to and I've done my entire top with Acoustic-Thermal insulation, but

The instructions were to make sure the foil side, is on the heat generating surface--so it helps reflect the heat, so mines against the inside of the top--

My JK is very comfy at 115 deg in the Nevada desert and I guess any insulation you add to the insides of these bricks---Helps !!!

good job

JIMBO

So, did you glue the foil side to the inside of the top?

When you did your "new headliner" did you wipe down the surface with brakeclean or rough it up ........ or just cleaned it well ? Is it still completely intact after the year ? I am thinking of getting insulation in there for the -40 days LOL ! And am wondering about the longevity of the adhesive , if it stays stuck in your heat it should stay stuck in our cold ..........Thanks

I actually had some mud and stuff on the inside of the roof. I just cleaned it really well with just soap and water. I used quite a bit of the headliner glue installing the headliner. It's still stuck.
