sound deadening material
I spent the afternoon searching through the site looking for recommendations for sound deadening material for my Suburban. Since it's a Suburban I'm going to need a lot of it and some of the stuff is wicked expensive and I'm cheap. Lots of the old threads are 5-6 years old and I'm not sure the comparisons are up to date. So, what are you guys using?

Re: sound deadening material
For the DIY'er...Jute padding is a good option for the floors along with a thin, flexible rubber matting (or not). This all depends on your application. Peal-N-Seal roofing is a very good substitute for sound deadener (dynamat). I do not advise putting peal-n-seal on the underside of a roof or on vertical surfaces like inside doors. It is a tar-like substance and can get hot enough to let go and gum up the works (dynamat is a butal rubber with adhesive). Peal-N-Seal works very well for floors and works well for firewalls and such given that there is a firewall pad or the like over it in case it does let go...it won't go far. Many hardware stores carry it in narrow strips...you just have to shop around and find it in 3 foot wide rolls.
I have done two vehicles and have learned to cover the wide open flat spots with peal-n-seal, cover that with thin jute padding, then thin rubber, then carpet.

Re: sound deadening material
I like Kilmat. It’s made from butyl rubber with an aluminum skin. It very similar to that expensive Dynamat but the price is fairly affordable. The cheap solutions like Peel-n-seal are made from asphalt which can cause issues.

Re: sound deadening material
An important thing to note. You do not have to cover an entire panel with material to deaden it. Strips or patches will give good results. Making a panel "dead" and restricting sound from getting through from the outside are two different things to deal with.

Re: sound deadening material
I used Noico from Amazon. It's 80mil versus 50mil thickness for the Kilmat, at about the same price. It's a Russian company with the product being made in Russia and I have noticed the price fluctuates quite a bit, FYI. I found it after researching online. It was good quality. It makes a huge difference, it's not a modern car but it also doesn't sound like a tin can rolling down the road.
I would not recommend installing any of the Home Depot noise control items in one of these old trucks on the cab floor. These trucks all leak, and I can confirm that jute padding, tar pads, etc. All absorb and hold moisture against the sheet metal. They will also grow mold on the jute or the paper backing. Tar paper, jute, cardboard, and vinyl are what these trucks came with, but it's 2022 and technology has changed. |

Re: sound deadening material
Has anyone tried the roofing membrane that is used on houses as ice dam sealer. It stands up to the summer temperatures of a hot roof.

Re: sound deadening material
Has anyone tried removing these products and are there ones that remove easier then others? I want to add some to my cab, but in a few years I'll be repainting the cab and don't want to be in a position where it is impossible to get the sound-deading off.

Re: sound deadening material
I bought lizard skin. For 2 reasons.
1. Building a step side and I want to put a barrier inside the rear fenders so it doesn’t get a star in the paint from stones. 2. The stick down mats really look like a pain to apply with air pockets and rollers. So the only bad review I read on the lizard skin is that it is expensive. It’s a 3 part system that looks like it would take almost a week to get it all applied with proper drying. So we’ll see.

Re: sound deadening material
I used Kilmat from amazon. Easy to cut and put down. Pretty inexpensive, 36 sq ft about 60 for the 80mil. Good reviews on Amazon

Re: sound deadening material
Being a cheapskate myself, I intend to try off-the-shelf duct insulation for my next project, particularly in the doors and anywhere I think that the thickness of the material will not be a problem.
I have dynamatted a cab before and although it wasn't really that expensive, I like the idea of using something that doubles as a heat shield while being more affordable too. For something with the square footage of a suburban, maybe worth a look. The below product would need a little contact cement, they also sell this stuff with a built in adhesive. https://www.amazon.ca/Reflective-Ins.../dp/B01BDWY8ZG

We used Kilmat throughout... a bit cheaper alternative to the dynomat..

Re: sound deadening material
I will second/third/fourth on kilmat, i have used it on 2 different vehicles now and been happy with the results. I have used the Summit brand heatshield/sound deadening combo on my 72, from what i can tell its basically the same stuff as kilmat but you can buy it in huge sheets for pretty cheap. I wouldnt hesitate to recommend both.

Re: sound deadening material
5x Kilmat. Used it on my '89 Toyota pickup and it works great. Killed a lot of the road noise and helps keep the interior temp down. I have also installed it in my '67 also but it is not on the road yet.

Re: sound deadening material
OK all you ah-hem 'THRIFTY' gentlemen, here's the cheap ticket.
Gaps and cracks spray foam and some chip brushes!! Yep, everywhere inside you can reach in and won't matter if it's smooth. Just shoot some spray foam on the panel and brush it to spread it some. Works excellent for sound deadening and adds some insulating value as well. Works just as good on the backsides of plastic panels where there is space too! Less than $20 to do a whole vehicle!! Removal down the road......simply scrape it off with a putty knife! |

Re: sound deadening material
I liked the FatMat I used - purchased a roll from Amazon - seemed pretty reasonably priced

Re: sound deadening material
I used KILMAT from Amazon. 1 box covered the firewall, floor and back of the cab where my gas tank is. I have one more box to do the inside of my doors and the ceiling under the oem material. I also covered my KILMAT with 3 coats o Herculiner. Turned out awesome and between this and the Gear vendors unit should be nice and quiet. Good luck.

Re: sound deadening material
Thank you for all the input! Since I'm doing a suburban I'll look into the kilmat and start off with one order and see how far it goes.
Is it worth it to use the 80mil over the 50?

Re: sound deadening material
Yes, go 80mil. There isn't a lot of difference in thickness. I would advise 80 ml. Price is pretty the same also. Good luck!

Re: sound deadening material
I sprayed the Lizardskin Sound Deadener and Lizardskin Heat Barrier then topped it off with a layer of Flatline Barrier. With the jutted carpet it made a world of difference in noise and temp. The Flatline Barrier kit also came with pieces that stick to the back of the cab (behind the seat area), inside the doors and between the door panel and door shell. I did not save any of the pics with the Flatline Barrier but I do have some pics showing the Lizardskin. You can look at them on post "My 72 Cheyenne Super C20".
