Sound deadening Hack!

For years I have thought about this. The cost and time has really thrown me off. Being in the construction trade and dealing with water proofing materials often I thought a lot about using grace ice and water as sound deadening. The draw back is the smell.

For the good part. I couple years ago I was doing a rubber roof that lead to asphalt shingles. Supposedly ice and water being petroleum based can deteriorate the rubber so the alternative was a butyll based product. I recently searched and some folks are doing a similar install. Some went with ice and water which smells horrible in a warmer vehicle. (((Protector-wrap))) makes a 75’ x3’ roll and also multiple sized smaller rolls. Ranging from 4-12” wide and is butyl based. If it performs half as good which I doubt there is any difference id say it’s a winner. The cost would be pennies in comparison and there is almost no smell at all.

 

I am, by no means, a tree hugger. But there is a lot of recycled shit that goes into rubber and asphalt roofing products. I would not want to be exposed to an enclosed space with the chemicals that may be seeping out. Formaldehyde being one of the biggest that would come to mind.

Why not just buy something made for soundproofing. There are several members on here that have done it. A roll of ice and water barrier is going to run you $60-70.

If you are he'll bent on using roofing products get some EPDM. It is solid rubber designed to withstand to elements. But is going to be recycled shit probably.

 

I’ve used the ‘Peel and Stick’ window and door butyl rubber membrane all throughout my 2002 Tundra with great success. Its coupled up with HVAC Aluminum Foil tape and works great. I also save and re-use food delivery (think Hello Fresh and others etc) fiber insulation (very similar to the OEM). Check my build page for pics.

Not many around here believe me or have followed my advice on this. They are very inexpensive at less than half the price compared to buying outright labeled ‘sound proofer stuff’. The recycled food insulation is free. No smells and everything is safe and performs as the high dollar branded stuff. A no brainer win win.

If you think that butyl based protecto wrap is any different than butyl based dynamat or that dynamat is some healthy green product compared to protecto wrap my reply is a waste of time. I’m not suggesting someone buys a whole roll or ice and water. I’m suggesting a similar butyl wrap that cost 1/10th of dynamat. It’s one thing if you stick a 1x1’ square behind a door speaker but it’s another to spend hundreds on doing a whole car or truck. To think there is the chance of recycled material in this but not the others is just absurd.

 

I also, spent my life in construction. I’d suggest salvaging some of the closed cell insulation that is used everywhere and cutting it to fit the areas, using tape and acoustical caulking to fit and fill any gaps.
Probably about a tenth the cost ( unless free), and also, probably more effective.

 

Yes there is recycled materials in the other products. It is what is allowed in the manufacturing process. Products that are not designed to be in enclosed spaces are allowed to put really bad shit in there. Whereas products that humans will come in contact with are held to a much higher standard.

I am serious. I am involved in the manufacturing process and the stringent testing involved. There is no telling what is in it especially if it comes from China. I deal with a national retailer that tests every product for hazardous chemicals. Products getting failed because levels of toxic substances are too high even though the raw materials supposedly passed before the manufacturing process.

Look for prop 65 labels. Yes many are overblown, but when you have a little here, then a little there it begins to add up.

Look at the trailers that were slapped together after Hurricane Katrina. They were filled with formaldehyde from many products that were used. Not just the particle board. Couple that it is being used in an enclosed living space makes it bad. If the products were used outside, they would be harmless.

I really don't care either way. I'm just letting you know the products you are interested in using can have some pretty bad shit in them.

Take garden hose that has a prop 65 label. (Known to contain cancer causing chemicals) I m sure it is fine to drink from one if you are running water through it. But to drink from it while water has been sitting in it for hours, that is bad. Flush all of the water from the hose before you take a sip.

 

i think the food insulation is genius. I had a ton of that stuff at one point but pitched it. Should have used it under the headliner and in the doors. Oh well.

 

I wouldn’t use the food insulation in the doors as it might be exposed to water intrusion unless you encapsulated it in the butyl rubber peel and stick. In those places I’ve used water proof foam with peel and sick on the walls.

Back of cab and under all carpeted areas is where I use the insulation. Headliner is pretty well OEM insulated already in my understanding from a Toy tech member here.

 

I always wondered how a spray can of Linex or similar may work if spayed where needed. Not sure about drying time but inside the doors, backside of the outer panel, has to be somewhat effective.

 

Good point about the doors. There actually isn't much insulation under the headliner, at least in my 07. Lot of space between the roof and backside of the liner with a thin section of insulation.
