 Posted: Mon Mar 02, 2015 8:45 am Post subject: Interior Thermal Insulation behind door panels? |
 |
|
Good morning all.
Forever the de facto standard for interior insulation in our buses has been the foil backed bubble insulation.
Has anyone uncovered any insulation that works better than this, and won't hold moisture and rust out our buses?

I'm sure this would work to some degree although probably more useful in a heated interior/cold exterior. I know some people who used it inside their boat and it eliminated condensation.

That stuff looks like it probably works great, but I wonder if it retains moisture like other types of insulation?
The last thing I want to do is rust out my bus due to insulation.

lizardskin is a coating, no rust here. It also can do both Thermal and Sound insulation

Mr. Electric Wizard,
You're getting replies for both acoustic and thermal insulation. Was there one type you're interested in... or both. If one... maybe adjust thread title to be more specific.
I used a spray on Noxudol 3100 series product for acoustic insulation.. + foil backed bubble wrap.

Good point (I modified title).
I've already got Fat Mat on the interior metal throughout the vehicle.
I'm getting ready to install wood paneling and would like to get some additional thermal insulation installed before doing so.
Do you feel like the foil backed bubble wrap provides adequate thermal insulation? ie. Can you feel a difference?

My bus is not done yet, so I can't say how it feels. I'm using the foil bubble after a fair amount of reading on this site & reports of favorable results, relative cost, low tech & easy install.

Yes, I can feel a temp difference with the reflectix type foil bubble wrap insulation.

Clara, do you place it loose behind the panels or use some type of adhesive or double-sided tape to hold it in place?

I've gone the solid insulation route on my solid walls. Time will tell if it was smart or dumb, but I can remove it easy enough if I am unhappy with it. I am torn whether I need to put a moisture barrier between the insulation and the wood panel.

It does not. It was designed initially for boats. It is hydrophobic and you have a choice of foil backed for more heat retention. Hey, they make ski jackets out of it, so it must be warm and water resistant. Plus, even the new Mercedes have it in them, so it will not be a rust creating source.
Gordo.

I don't like the smell of most adhesives. I just put the pieces under the panel and leave them loose. I have used loops of masking tape for large pieces under (above really) the big roof panels, to hold them in place until I get the roof panels in place.
This DC has loops of tape holding the larger pieces in place, at the front the insulation stays in place just tucked into the roof
I've used this stuff because it is easy to use, not messy, no off gassing smells. It does not hold moisture. You can remove it easily. Not expensive.
I am sure there are other forms of insulation that are good as well.
The DC truck did not have heat, but the guy whose truck it was said it was much quieter after the panels were in. No sound deadening was used, just the reflectix and the interior panels.
Funny, that 61 kombi I put the interior in is back up for sale.
I use 1" hard foam in the back corners, which I find just wedges in place w/o adhesive.

 Which route did you take on your tile grout? Sand or Non-Sanded?
J/K bro...wish my bus was half that clean inside!
