Insulation for noise, heat and cold

I had my cab reinsulated a while ago I used rod pickett husmat for the insulation. It's about 200 for 25 sq. ft. I got charged I believe 150 labor at a small shop and labor was 65/hour that's on a pete I don't know what it would be for a freightliner but isulation alone you're looking a pretty penny. I ordered mine from 4 state trucks I don't know if anybody else sells it cheaper but I know it's available from more than just 4 states. Good luck that stuff is pretty amazing though makes hellactious sound proofing too I've got 8 inch straights and yes you can hear them in the cab with the windows up but faintly roll the windows down and you can't carry on a conversation so that clearly says something from the product. matter of fact I was on the phone Friday and had the window down while I was waiting for the stoplight by the yard to change when I took off my friend said "jesus Christ can you get yourself a louder truck?" rolled the window up and no complaints.

 

When I was into car audio I tore my navigator apart and sprayed the floors doors roof with a product "secondskin" sludge then over that I put their second skin damplifire deadener all over then for the floor I bought their luxury liner pro to put underneath the carpet softer floor and Road noise was #### near not there anymore no vibrations and with 4 18" speakers over 155 decibels kept all the beautiful bass in. But also kept cooler during summer warmer during winter. Because it was sealed up really good.


When I got my first freightliner it was a 07 during winter I always froze to death and probably died a few times and I was going to insulate the whole truck but I got rid of it before that happened. I highly recommend the second skin if you have the extra money for dampening.

There is other companies like dynamat,hushmat, peeled and seal(cheap at Home Depot) you can use that on the floor but not roof and walls

Yup it's easy it's just the labor of taking everything apart and putting it back together. But well worth it

 

I ordered my last 3 peterbilts with factory insulated cab and sleeper..it does make a big difference when cooling or heating the interior of the truck , In cold weather it stays warm inside for hours and cool in the summer.
I compared my truck to a friends in Denver one winter,we were in the truck stop eating for a couple hours, When we came out his truck was cold inside and mine was still warm , it was 15 degrees at the time
In the summer I would run the sleeper A/C during the day and once the sun went down and I parked the sleeper stayed cool for a few hours..It does make a big difference

 

I did my Marmon myself . I took out all the panels and the cheap factory insulation and replaced it with the pink rigid insulation. It is quieter and stays warmer and cooler too . I went from about a 1 R factor to about 7

I did it over a weekend so it isn't that big of a job . Do it in the spring or fall so it wont be so miserable inside that cab !!!
