Homemade Sound Deadening Panels - A.K.A. Pinche Mat

[pincheweddo]

I did the following in the roof of my F'er today. I am absolutely stunned at how well it worked to stop the roof from sounding like a tin can. I did a ton of reading and though I thought my idea might work, I must admit, I didn't think it would work this good! Wish I had done this to the back wall of my cab instead of the peel and seal. It will be what I do to the doors!

Expanded foam PVC yoga mats come in many colors. To do this right and really knock the sound down, pink works best.

Materials needed

1. small paint roller
2. razor knife
3. 10" x 10' Aluminum Flashing ($9) (100% Silicon in a chalk tub works better and is cheaper)
4. 1 cheap PVC Yoga mat (My wife hasn't missed it yet)
5. Contact cement use for counter tops. ($9)
6. Glove
7. Rolling pin

Process:

1. Lay out flashing on yoga mat to mark area to be glued.
2. Apply glue to the Aluminum and the yoga mat and let dry for 15 min.
3. CAREFULLY lay the aluminum on the yoga mat and roll with rolling pin.
4. Trim excess and repeat until all flashing is covered.
5. Cut into 26" lengths
6. Using one of the pieces to be glued, mark the roof for the glue areas needed.
7. Apply glue (glue failed so used silicon in chalk tube instead) to the yoga mat side of the panel and the roof, dry for 15 mins then smooth the panel on with pressure of a gloved hand.

Way to show some creativity and initiative!

I don't come up with original ideas often, but when I do, I will gladly take the credit for it! Thank you sir!

very cool, i was thinking along the same lines after reading that other thread. having removed tons of asphalt sound deadener from cars over the years, i couldn't bear to apply it willingly.

This stuff would probably come off with a wire wheel in about a second!

I've got some laminate floor underlayment, basically a 1/8" closed cell foam with a 6 mil poly sheet backing... i think i'll try that and see how far it goes.

the biggest fear i have is somehow trapping moisture and condensation between layers.

are you planning a headliner? I'm curious to see what you do for that. my perforated masonite is totally shot. Nice blog btw.

Thanks for the blog kudos! I was staring to wonder if any you good folks were looking at it.

Stuff sealed pretty tight. I am not concerned about moister.

For headliner I have a line on a piece of Kydex. The stuff ain't cheap but neither is a new headliner. I intend to take the kydex and stick down some Frost King duct insulation so the foil side is facing up towards the roof. Kydex doesn't start softening until 250 degrees and it is flexible, fade and stain resistant, and best of all it was made to be headliner for the airliner.

Addition to the yoga mat panels!

The contact cement for the mat to the Aluminum held up really well. However it did not do so well in the Texas heat in between the panel and the roof. The panels dropped off this week. So I am going to give 3m Spray 90 adhesive a try. If that don't work its liquid nails! Stay tuned I will keep you posted as to the performance of the glue saga.

I think you need some sheet metal screws and a bunch of trolls

Might look like this though.

Hey, with the trolls you don't notice the rust as much!

[Heirloom]

Bwaaaahahahaha!

[pincheweddo]

Damn it! I wish I had seen the troll idea before finding the tube of black silicon. I can't imagine how quiet my ride would be with 50 Troll asses on the roof. Oh well maybe on the next project I can press troll butt to something. I bet that dude has to keep a lot of change for the "troll bridge" and "troll roads"

In the mean time, Black Silicone works well:

Looks good, I'm not this far along on mine but have spent a lot of time wondering what I'm going to put up there to quiet it down. I did the microscopic glass beads in white roofing paint and that really cut down on the heat transfer but it's still pretty loud without the stacks.

The Silicon worked well. So well in fact that I think it is better than before. Absolutely no trash can sound. I can't wait to get it on the road. No reason to go buy expensive materials.

Kudos for the ingenuity!

How thick is the aluminum flashing? Any concern of it coming unglued from the mat?
