We recently got our first cargo van for our company. The road noise is so loud when driving. What do you use to insulate the noise? They sell insulation packages for the cargo area. Does anyone just insulate the cargo partition?

I traded my factory steel partition for a nice conduit rack and built my own. I used plywood and contoured the partition to the back of the seat. I covered it with an auto grade carpet. Not to much noise coming through that, and it looks real good.

NAPA sells tar-paper like adhesive sound deadening insulation, although this might be the most expensive route you can go considering the cost/vs size of adhesive sheets. Another option is go to home depot and get some heavy rubber mats cut to cover the floor area. sound deadening is a tricky art- there is a reason that a lexus and a mercedes are quiet, which has to do with how the car is engineered from the ground up to deaden sound and be quiet, something that is not even added into the cost equation for something as utilitarian and realtively "cheap" as a service van. There is only a certain amount of deadening that will even be possible due to the design of the vehicle. Not to discourage you, but just something to keep in mind. Sound waves transfer best through substances that are dense and uniform, and transfer worst though substances that are amorphous, which is why I sugest heavy rubber mats. Sound deadening materials used in car wheel wells etc. are tar or asphalt like for this reason- on top of being cheap they are molecularlly amorphous substances that tend to absorb and dissipate sound waves rather than transmit them. Same is true of rubber mats..

20 mil pipe wrap, how many rolls is up to you.

And seeing that you just got it. This means it relitively empty. In a month or so when its 3' deep all the way across, it will silence itself subtantialy.

Thank you for the good info, it should really help us make some decisions. This is the first time I have used this forum or any forum. I think it is great.

If it is road noise you can try undercaoting. Also carpet padding under the ruber floor mat (assuming it came with a ruber floor mat).

Inside steel shelves are solid but things can rattle. If you have them you might try putting somthing on the shelves like thin wood, ruber, carpet. I like wood shelving to keep the rattling down.

Sometimes you have to figure what makes the most noise. What ever is rattling try experimenting. Sometimes it is a little loose and needs another somthing to hold it solid. Other times to parts are rubbing tugether. Try insulating with a piece of rubber (old cut hose, floormat, weatherstriping).

You did not say what type of truck you have.

Buck, if as e57 said, the van is empty, don't even give it a second thought. The difference between an empty van and a full one is amazing. Of course, it still won't be like a pickup but the difference is substantial.

It is a new 2005 Dodge Sprinter. The thing is, it doesn't even have a cargo partition installed yet. We were looking at insulation kits at sprinteraccessories.com, after all the advise, I think it is better to just wait until we get the partition installed and outfitted with our gear. If it is still noisy, we were advised to put plexiglass over the holes in the partition. I also like the ideas posted about rubber mats and all the other ideas.

Hi,
One fo the best cargo partitions I have run across is the plexiglass one. It keeps cold air in in the summer and hot in the winter.

An empty van will make a lot of noise..just use it for a week or two I am sure it will go dissipate.

But really, you can make a plexiglass one easily. I have seen them with sliding trap door so you can get some small stuff through.

A little less helpful, but you will get used to it. It's funny when I give someone a ride, like a nephew or aquaintance, the looks of disbelief I get. "Man it's loud in here. Is it always this loud? How can stand all that noise all the time?" Then I have to conciously (sp? again. no spell check on the wife's mac) listen to hear what they are talking about. I just tune it out after a while. I'll hear it again after some time off or a long weekend. One suggestion not given is to turn up the radio.

But I think the most difficult noise to try to drive through is when a big box of small parts has tipped, but is lodged from fully spilling, but every little bump you hit, a few more parts hit the floor. After about 10 minutes it was worse than nails on chaulkboard and i had to pull over.

I bought rubber mat from Americanvan for over $200. I remember after-the-fact seeing something similar at home Depot for less than half the cost. If you can try avoid buying something made especially for this purpose. Try to see what the material and technique is and find something comprable. You'll save.

Jps1006, i hear you about the bumps spilling stuff. my wiggins got bumped around one day and was reading continuity on something...after about 5 minutes i had to pull over.

At All costs buy a metal divider. from americian van
or who ever. with or without a door.
I was in a bad crash once and remember watching a tool box fly by my head and blowing out the windsheild
after that i never drove another without at least a partial one in back of the driver seat

Wieght is a big factor. If you have a van with not enough weight for the suspension it will ride hard and it wil feel like you crashing into every bump in the road. If it's too light load it down with more weight and it will ride much smother. When it rides smoother there are less bumps to make noise.

Also check your tire pressure. Some auto manufactures put way too much pressure in the tires. I can't say if it is to help the new tire seat, to compensate if it does have a slow leak, or a tempiture thing. The dealer should have checked that with a new vehicle inspection but you never know. It should say in the door jamb recomended tire pressure. If you go on the lower side of those numbers it will ride smother.

I just got a new van for work about four months ago, Ford E350 with metal divider and plastic shelves. They have the normal metal sides but plastic shelves with two aluminum bars under them for strength, they are speced at 200 lbs per shelf. There is almost no rattle from them and now I can finally keep the radio at a normal level. It also helps if you have to make a phone call from the road, don't have to deal with all the background noise asking people to repeat themselves. Not sure who makes them but they came from the dealer with the truck.

When I am ready for a new van I was thinking of having the inside sprayed with the bed liner spray they use on pick up beds.
