Thinsulate insulation thickness?

Looking for some help full experience with Thinsulate insulation thickness?
Getting ready to start the interior build, looking at the options for Thinsulate, bit confusing with the amount of thickness choices.
All help is greatly appreciated.

Thank you very much. Joe

PS. is thicker better, or if it is compressed does it reduce the value?

If you compress the insulation, you end up reducing its effectiveness. In that case you may be better off using the thinner one which should be less expensive.



I used 3M SM400L. I chose that over the thicker SM600L and am glad I did. For me, the 600 would have been too thick to work with on my fixed top. Not sure about the sides yet. I know some members really liked the 600 though.

I just installed the 600. 1.5” thick. You can compress it if needed to fit somewhere but yes it will be less effective.

I used the SM600l as well.

Side question for you have used the Thinsulate on Econolines...

I stuffed the Thinsulate into as many spots as I could on the walls but on the driver's side wall, there are not many places. Did any of you add a layer against the interior wall to act as another barrier?

Thinsulate insulation thickness?

^^^yes, I cut pieces and used spray adhesive to fit them into as many places I could into the smaller cavities on the exterior skin and then came in with a large sheet of it over the interior and cut the windows and contours before the wall skins went in. I also put in a layer of sound proofing before the thinsulate insulation.
I looked back at my interior rebuild thread, and it looks like I thought it was the thinner 21mm SM300L I used. The 600 is 42mm or 1.65”, I’ll see if I can confirm....
