Hey guys, I was at the new Lowes tonight (5 minutes from my house and I found this roofing stuff that might be useful for sound deadening:



Any thoughts?

 

That just might work. I think the biggest worry would be the smell. Some roofing products have a strong tar smell.

 

just to let you know there is also something else that works great and is cheaper that store bought audio deading material it is just like all of the other deading material it also can be bought at any great hardware strore. it is used for sealing sliding glass doors and windows I cant remimber what it was called ill post that as soon as I find out the name. I did almost my hole car for around 50.00 and and it little to no differnts. its tar like on one side and fiol like on the other side. the roofing stuff might work to but the wait time and the smeel might just make you sick..

 

That stuff is asphalt based. It will run in hot weather. It also remains tacky after it "cures." The stuff onionescion mentioned is asphalt based as well and will eventually peel away in hot weather (not to mention it is extremely thin and will not deaden that well).

Stick to something butyl based, Like E-dead, B-quiet, etc.

 

Thats it I believe this is butan basded this is not asphalt based aslo I have had this in my car for a few years this does not peal off at all this is no differnt than most if not all deadening material.

 

The guys in DIYmobileaudio.com are very much NOT in favor of that stuff, so I asked what else they might know of... we'll see in the next 24 hours

 

Rubberized undercoating does well. Just make sure that you get the one that dries and not the one that stays tacky (unless you want it like that). It is also paintable once it cures.

 

Unless they've changed it recently, I remember it being asphalt based. I used to work at Home Depot in the Building Materials section (where you'll find all of this stuff). The gutter liner is also extreeeeeeemely thin, so you would need a whole lot of layers to deaden effectively.

The rubberized roof patch will remain sticky (we had to clean that crap up a number of times after someone hit it with a fork-lift). It also never cures hard so it will still be able to move/drip if you put it on any slope.

 

What about spray expanding foam and then cutting away any excess???

 

Works yes, but has no where near the sound abatement capabilities of a good sheet type product like Raamat.

 

Works also, sloppy to work with tho, and you must be very carefull where you put it depending on the product. Is also not that easy to cut away the excess. Home store expanding foams used in house construction if applied between 2 layers of sheet metal might cause buckeling of the sheet metal as it expands. There are specialty expanding fooms made for automotive use 3M has a few different ones in fact. They have a soft foam that wont buckle panels if applied between them...it is expensive as hell tho....it is usually used to stop noise and air infiltration in roof pillars and door posts.
If you want good sound deadening and easy installation without a bunch of fuss and mess you can't go wrong with a pruduct designed specifically for this purpose. Dynamat, RaaMat, Edead and others are good choices. Reseach I did indicates that Butyl based materials are better than asphalt based.

 

OK I found the name of the company that make this stuff is called polyken and can be bought at any great hardware store it is butyl based and is used for window flashing in houses water proof and on there web site comes in up 33 mils thick material also 1/10 th the cost. But the best thing about this is the procedure of installing it. all you have to do is wipe area cut and stick easy not cemicails no rollers this stuff is so sticky you might not get it off after installing. dont have to heat it either this is the best stuff out their that I ever used...

 

so is it a peel and stick onionescion?

 

Has anybody sucessfully use this stuff

 

Yes it is peal stick move to the next area that quick!!!! Well Ill have to say alot of people every day the use it for house flashing also ive seen upohlstery shops use it for the same thing.

 

Well, I wanted to get some spray foam for the hatch to spray between the sheet metal. I can't see how else one would sound proof the hatch.

 

I have it in my car for 2 years now too.

 

I used the pink stuff. That's right, the pink home insulation. It's made to insulate, reduce noise, and is flame retardent. I just cut it in small enough pieces to get it in the openings and stuffed the whole door. I have NO rear hatch rattles when I crank up my system now.

 

Hmm... I remember looking at this stuff in the store a while ago and it was Asphalt based. This could be used areas that just need a little deadening, however it is no where near thicker than other sound deadener products.

Wow Now I could have read the material sheet wrong on there website but ill check again nope did not think so it is a butyl base unless the make asphalt with butyl it is not aspalt base. but I could be wrong. who realy knows what the put in asphalt. just to let you know that the price is a lot cheaper like less than .60 cents a square foot and weighs less too. So even if the first layer is not the second layer still only csot you less than .60 cents.
