Sound Insulation The Cheap Way

[Pilotman]

Ok you got me thinking here

Pilotman,



I did some research on the SBS materials based off of the www.branz.org website you posted. This particular type of material has a maximum operating temperature of 50*C or 122*F. The melting point is 160*C or 320*F. It is somewhat flame resistant and has a flamability rating of HB for horizontal burn. This is under UL 94 HB standard for slow horizontal burning on a 3mm thick specimen with a burning rate is less than 3"/min or stops burning before the 5" mark. H-B rated materials are considered "self-extinguishing". This is the lowest (least flame retardant) UL94 rating.



As far as the temperature rating, I think that we would need a minimum of 150*F for inside the cab due to the high heat that can develop inside of a parked vehicle on a hot day. I've had thermometers inside my truck before that pegged a 140*F gauge.



I haven't checked the ratings of the more expensive stuff yet, but will do so when I get time.

Ok you got me thinking... . Im going to set up a test rig here and see what the stuff will do in high heat. Ill start with a door install mock up. Ill put a high intensity light on it and a thermacouple to test the temps. Ill post it as soon as I have it going for a day or two. I also have some of the expensive stuff called HushMat too and will be testing that at the same time.

Home Depot sells a similar product called Protecto Wrap BT20XL for $10 for 4" x 50'. I just used a couple of rolls to install some new windows. Nice product. Has adhesive only on one side.

Might be the same or not. The stuff Im using has it on both sides which is nice for putting on the foil. Although it is $16. 50 for 50' x 6".

Ok..... Im set up for this test. I have a peice of sheet metal painted black on one side to simulate the outside of the truck which I am heating with a 150 Watt garage light. I have my temperature meter hooked up. On the exterior Im reading around 16o F surface temp. On the inside Im reading around 140 F. So far everything looks great. I tried to peel back one of the strips after about 3 hours of sitting at these temps and it felt like it was stuck even better that the begining. The HushMatt seems to be more gooey than the jiffey seal. Im going to leave it on for tonight and monitor the temps. We will ses what the effects of 24 hours at 160 F exterior will do to it. See if we can break it!!

Can't find it...

The people at Lowes looked at me like I had 2 heads when I tryed to order some Jiffy Seal and that was with the stock number. I found something that might be similar only 4" wide. My question is how thick is this stuff? The stuff I found was much thinner than I expected, maybe 1/16th to 1/8th inch. Thanks for any help.

Tell those fools to call the Burbank, CA store and give them that stock number. They shouldnt have a problem getting it in for you. The stuff thats 4" is no good! Dont use it. If its the same stuff that Home Depot sells that is!

Ok guys! After a 5 day test at the above listed temps all is great. no problems up to that point. I really think I got a winner here!



Enjoy Oo.

Interesting test, it's great to have real data that it holds up to that temp.



But how do I know if those temps are similar to the inside of the enclosed door space while the vehicle is parked in the sun?

Nice work Pilotman! Thanks for going through the effort, I think your test is pretty realistic and adequate for our summer sun.

If this is what you're talking about, here's there web site:

It comes in different sizes. Any roofing supply would probably carry larger the sizes.

Totaly diffrent animal! I know nothing of it. Its roofing stuff so chances are its not even close to the stuff Im using.

 

[Pilotman]

Left it in! Its a moisture barier and dont think you should remove it.

Wanted to post this for everyone that would love to have there truck as quiet as a lexus with out having to spend $3000 big ones to have someone at a stereo shop do it half ***. I found this stuff called Jiffy Seal at Lowes Hardware for $16. 00 per 50' x 6" role that is used for sealing the edge of windows in construction. It is made of a tar compound that has adhesive on both sides. I compared it to a popular sound deadening material called HushMatt. It was very close in thickness and was just as sticky. The difference was that the Hushmatt has one side that was foil painted black and cost about 300 times as much. I had my wife while on a weekly market trip pick me up the heaviest duty role of tin foil she could find. After pealing the first piece and adhering it to the tin foil and trimming a bit I found that I had made the same exact stuff as the HushMatt for the most part. A Hell of a lot cheaper. Oo.



I started with the inside of the doors and worked my way to sealing all the interior surfaces of the doors and the holes that they leave open from the factory. There is a source of a bunch if noise right there. If you tap on the exterior of the door before the matt is put on it sounds like a drum. The difference is astounding.



I took it for a test drive and found that the doors sounded great but I could hear a source of more noise in the back seat. After taking all the back seats and hardware out I saw what equated to a large drum back there. I covered the entire rear cab facing the bed and then pulled out the floor matting under the seats to find the same issue. The carpet is pretty good at killing the sound due to its foal underlayment but this stuff was 1/8" thick of nothing.



One really bad source of noise was the cabin pressure vents behind the rear seats. I did seal those up but I am not reconsidering opening one of them up due to the high cabin pressure when the A/C is on even the low setting. On high I felt like I was in an airline with pressurization problems. Figure I could always get in the truck if a have a diving accident and need a pressure vessel .



The difference is night and day :--) If your looking for a way to make your truck nice on long trips, This is the way. I will post before and after tests with a sound pressure level meter here soon. I will go for a test drive at the dealer with a stock unit on the same street, speed, and lane as I test mine. I can’t wait to see... or should I say hear the difference.



Enjoy,



Adam

Just an update for everyone! I have had the same test peice out in the sun sitting clean side up to simulate the roof. The Jiffey Seal is up there like GLUE!! Oo. This stuff is never comming off!

 

[Pilotman]

An update for everyone! I have had my test peices in the sun clean side up on the metal sheet I used in the inital tests and the stuff is never coming off. I was worried about ozzing over time but none of that here.

12 sqaure feet for @ 54. 99... ... Holy crap. I have put 4 roles of 6" x 50' in my truck. Your way thats $2. 29 for a 6 x 12 piece. Im paying . 33 cents per 6" x 1' plus the cost of the foil to put on the back. Doing it your way would have cost me $458. WOW... ... ... ... ..... NOT!!!!



The b-quiet also comes in 12"x50' rolls at 119. 99. So if you used 4 rolls of 6"x50' or 64 dollars plus adding foil for backing. . hmmm.

The same amount of b-quiet would cost 249. 97 shipped to your door. The b-quiet is also rated at -76 to 311 degrees fahrenheit.

It is still more expensive than jiffy seal (around 100 dollars or so with backing and taxes?) but not having to mess with the aluminum and has deadening characteristics close to dynamat makes it something to consider I think.

Interesting stuff that www.b-quiet.com

Only thing is, their site makes me confused on which of their 4 different products to use. They have this comparison page that you must study to learn the products.



Would be cool if the Engine Performance vendors did that but studying sound deadening material is boring to me.

 

[DSpencer]

If I get crazy and pull the interior of the new truck, the second roll will go in the new truck.

You're just like that little kid who gets a new toy and takes it apart instead of playing with it.

:-laf I think Ryan has that covered in this thread :-laf

No offense to Ryan at all, great stuff. I spent a considerable amount of time myself in figuring a way to turn on the vistronic fan without a check engine lamp.

Hey! Only way to figure out how things work is to take 'em apart. At this point I almost know how everything works. :-laf
