Best bang for the buck sound deadening location!
Check out the video about sound deadening our Buick if you wanna see more.

We're decibel testing the installation of butyl rubber mat and foam on the floor pan of our Volvo 240 project car. I went with Siless 120 mil thick peel and stick mat and their Siless Liner closed cell foam.

Great video! Thanks for measuring the decibels so I don't have to. 😂

[@timelordnoah5179]

It’s definitely worth it for the insulation alone in my opinion. Thanks for all these videos!

[@MatthewFinlay]

It was impressive buddy! I knew it was doing something but a 20+ degree difference after 30 min drive is nothing to ignore.

[@timelordnoah5179]

@@MatthewFinlay you definitely have the most in depth videos on it. Have a 95 bronco I plan on doing it with.

@timelordnoah5179 Awesome - we have a 1995 F150 so I completely understand your world haha

[@ernestochamorro1]

so kilmat 100mil vs siless 120mil? which on would you go or ? vibration and heat. Thank you

[@sas8403]

how thick was the foam, is closed cell foam very soft, did you use mass loaded vinyl ontop of this

[@MatthewFinlay]

Ya'll are great! Hope you enjoyed the video and let me know what you think.

It was weird to watch a video with my pants off.

Hey I already have the butyl stiless installed in the floor and roof, and the closed foam you installed here looks extremely interesting!
Q: How well does the closed cell foam stick/ stay stuck on top of the butyl? Especially on the roof, you think it will stay stuck??
Thanks! Great videos! I learned about 4 way stretch vinyl from your previous video.

[@MatthewFinlay]

Hey thanks buddy - I’m glad you learned some tricks! It sticks darn good unless you stretch it I’ve found. If you pull the crap out of it, it likes to shrink back. I’ve had it installed for over a month with no issues on the firewall vertical surface! Pretty stout adhesive
