I tried to follow the thread posted about the window flashing material from Lowe's / Home Depot..

I went to both places yesterday, and what they had was foil backed(not a problem), but butyl-rubber based, and pretty darn thin. I wasn't sure that it would do the job, so I looked around more, and all I could find was actual roof material.

It's also self-stick, meant for flat or slightly sloping roofs, is asphalt/tar based, BUT... It's got that rough roof-like surface on it. It's certainly thicker than the other stuff, but I'm a bit nervous about it not conforming to the panels inside the truck.

I HAVE to do the truck TODAY, the temps will be getting too cold again, and I need to put the interior back in!

Try this stuff.

 

Needed it today, and there's no way I'm spending the hundreds of dollars for enough to do the whole truck..

I bit the bullet and exchanged the roof stuff for the thinner rubber stuff after reading that the butyl rubber is actually preferred.

It's quite a bit thinner than the premium sound deadening, but the price is even moreso. Hopefully it makes a little difference. I used 1 layer on the floor, and 2 layers on the back wall. it was 6" wide x 75', used 2 rolls to do this much, saved one more roll for the doors. $19.97 a roll.

Wow, nice work Eskimo, how did that work. Is it a lot quieter?

 

Looks good. How hard is it to get it off if you had too.

 

So Eskimo, it's been a few days, what's the verdic on the thin material? Sure looks like it should help out.

As a added benefit, you don't have to worry about the floor rusting if you get a leak.

Oh yeah, I meant to update this.. All in all, it works!

It's no lexus, BUT - my 1900-2000 rpm drone is MUUUCH quieter, now it's only a slight flare in the noise level, and all in all, things are a bit quieter. I noticed when looking at real dynamat, this is about 1/2 as thick or so... but geez, it's gotta be 1/4 of the price or better!

After it fully cures, I wouldn't even want to think about trying to get it off, but why would you?

Worth the $40 for the cab + $20 for the doors, yeah. Really let the stereo shine.

If I wasn't already tearing the interior apart, I don't know if I'd go through all the trouble, but since I was, why not.

 

I've been wanting rip my interior apart and install some sound deadening stuff to help the stereo shine better. Where'd you get your stuff? It's a heckuva lot cheaper than dynamat.

 

Home Depot / Lowes

 

What is it called again? Also you said about 1/4 the price and 1/2 as thick? Could this be double layered? Then it would be just as thick as the Dynamat but still only 1/2 the price.

 

It's window flashing... used during construction, to seal around window openings.

Don't quote me on the 1/2 and 1/4, just going off rough estimates. The stuff I bought (20mil thick) is not foil-backed, if anyone cares.

I can't remember the exact name, but it's 6" wide x 75' long. There were some others, I remember a 4" x 33' roll for under $10, but when I worked out the square footage, the 6" wide stuff was a better deal.

You certainly can stack it.. mine is overlapped in many areas, and the rear wall has 2 full layers on it.

temperature makes a HUGE difference. the 60* day, the stuff was ALOT easier to work with and stuck better than on a 35* day. I used a heat gun to help get into some of the compound curves. I also bought a small wooden roller in the flooring area (for linoleum flooring), but I found it to be only marginally useful.

I based my thickness estimates on eyeball, but for price, I saw a kit with 2 10" x 10" pieces of dynamat for $13. not even 2 square feet. For $20, I got 37.5 square feet, so if you double it up, you get about 19 square feet.. so it's maybe 10%-ish of the cost?

I'd love to see someone who does 2, 3, 4 layers on their whole truck.. it took me long enough to do 2 on the back wall, and 1 everywhere else that I didn't care anymore and just wanted it done.. LOL

 

nice job!
i am going to do that from lowes/home depot and use the foil backed as it will help with the summer heat and winter cold too. i will also double layer. again nice job and i know how time consuming it is to R/I an interior. do it all the time.

 

From the pictures, the product looks like a flashing called "fire and ice" or, and this is a word, "bitchathane". It is a rubber compound that sticks on, and once it is on, you will never get it off, a great product for flashing, don't know about soundproofing. It is definitely worth a try. Be great if it works! I bought 1" foam rubber from McMaster-Carr and glued it in, then put the floor rug on top of that. I also took spray foam and filled the interior of both doors with it, leaving enough room for the window to go down.

 

Cool Thanks for the info. Hmmm I wonder if doing a 2nd layer 90^ from the first it would help anything. When I tear into the interior again, to do the stereo for the hopefully last time, I will be doing something like this. What what about a bottom layer of non foil backed, under another layer of foil backed??

 

It's the same exact composition as the premium sound deadeners, just not as thick.
