Design Engineering 050133 Boom Mat Grey Sound Deadening Headliner Compatible with 4-Door Jeep Wrangler (2007-2010)

I believe it prevents, or inhibits the transfer of temperature. I was leery when I pulled it out of the box wondering why couldn't I have just cut my own high density foam and save the money??? The foam I was going to choose was $100 a sheet. My time cutting it is worth more than the $100 difference! Prior to installing it in my 4-door Rubicon, the interior temps would be in excess of 130 degrees on an extremely hot day and wouldn't cool off for miles. When I would arrive home, the roof would still be extremely hot to the touch. Though it was later in the season when I installed it and the daytime temps were running a bit cooler, it seemed that the interior temps were running close to 15 degrees cooler when I opened the jeep after work. I wrote this off to the cooler days though they were running in the 90's. During intallation I was pressing it with my hands, I felt it getting warm almost immediately. I thought it was my imagination or maybe the sun. I just blew it off and was happy with the looks, and besides, it couldn't hurt with the road noise. Well now it's getting cold and dropping below freezing. In the morning when I get in I will put the back of my hand on the liner and you can feel it warm up and hold the heat immediately! Move your hand to another part and it will do the same, while the rest of the interior is cold. Just a few miles down the road, the roof (liner) is warm just from the defroster! If you install it in a 4-door, GET AN EXTRA SET OF HANDS TO HELP, you will need them!

The headliner cuts down on noise/echos dramatically. I only have to turn the stock radio to 10 or so to listen now. Before the headliner it was at least 18-20. My kids can talk to us from the back seat without yelling. On chilly days we don't need to use heat after a few minutes because our body heat keeps the cab warm. The ac works better in the desert heat too. Installation was a bit time consuming because of the dozens of little foam strips of different sizes to fill the corrugations in the roof. Once those were all sorted out it didn't take long to get everything installed.

Update: This insulation works so well that I installed it in my second JK. However, based on my experience with the first install (below) I recommend using 3M 77 Super Adhesive spray https://www.amazon.com/3M-Super-Multi-Purpose-Adhesive-Aerosol/ on the surfaces before installing the insulation, because I found that the factory peel-and-stick adhesive began to fail in the extreme heat of a southern summer. Using the 3M product solved the problem. Original Post - This insulation is nearly 1" thick and effectively eliminates the heat radiating from the top here in the deep south. Before installing it A/C had to be on high and heat still radiated from the top on your head. After installation, A/C can now run on low all day. Pros * cutouts accurately conform to the roof contours and installation is easy. * the package contains filler strips for the contours of the top, so the main mat will install smooth and not contoured. Minor gripe - the front sunroof pieces have cutouts for some of the rotating locks and not others. While this doesn't impair their operation (rotation), it's inconsistent to provide cutouts for some and not others. Note that the top must be removed to install the center panel, as the insulation extends between the top and sound bar. It is impossible to slide the mat into this confined space when the adhesive backing is exposed. It's also VERY IMPORTANT to position the mat correctly before allowing it to touch the surface because the adhesive is very aggressive, like duct tape, in grabbing and holding. Once it grabs, it's there. It's a recent install, so no data on long term performance of the adhesive in the heat. I'll update if it fails.

this is a must do , first the heat is gone inside the jeep , ice cold air now in 93 degree florida sun and the look is great , the factory should be installing in the factory. you will have no regrets , the install took under an hour

The Design Engineering 050133 Grey Sound Deadening Headliner fits perfectly in our 2010 Jeep Wrangler Unlimited Rubicon. Just follow their instructions and clean the surface thoroughly and then wipe it down with alcohol. The adhesive is very sticky so once it’s on it will not come off. It does make a remarkable difference in Temperature and Sound.

This did not fit my 2010 Jk 4 door wrangler and I was not willing to cut on it like other customers stated they had to do for install. That is ridiculous to have to do. I am hoping it was a one off mistake and will try ordering again. If it is wrong again, I will call the company.

I originally ordered the wrong (number) mat for my 2014 wrangler 4 dr, due to ambiguous advertising by amazon and DE. I contacted DE and told them about the bad ad in amazon and told them i had cut the mat i purchased to fit my Jeep and they said they did not want me to have a mat that was wrong for my Jeep. They then sent me a new mat to fit my Jeep for free, Now that Is SERVICE. Thank You DE. The mat works wonderfully for the sound and heat in the southwest desert!

I want to give this a 5 star but a few little things are preventing me from doing so. First the box came all beat up. (I know, it’s most likely from the mail carrier, not them) second the 2 bigger pieces were folded so there was a crease In The middle. But I was able to get it out with some bending and such. Then I was 2 or 3 strips short for the little foam strips that you put down before the bigger pieces. So we’ll see how that goes...the I structions we’re pretty basic and not very helpful. The video online was a little more helpful. Overall this looks cool but I do have some worries about how well the adhesive will hold up. Only time will tell. I’ll defiantly keep this up to date as we enter summer here soon.

Un indispensable para cualquier jeep wrangler, son caros a comparacion de otros como dd gele/algodon pero estos lucen mil veces mejor, y ademas dd brinda proteccion termica y acuatica mejora mucho la estetitca del interior.

Headliner is easy to install but need 2 people to do it. Not only is it sound deadening, it also provides some insulation from the heat in summer and cold in winter.

Easy to install, perfectly designed and works better than expected.
