Insulating the ceiling? HELP!

[grantgoold]

I have an MCI 9,without roof raise, and the original ceiling panels still in place. I want to add a decorative tin panel ceiling directly to the original panels. I was first thinking about a thin insulation between the two panels. I know there is insulation already between the panels and the roof is pretty cool during hot days. Should I add more or will the r value be so low as not to be worth it? I only want to go 1/4 inch thick or less. I have 3 inches of insulation on both inside walls of the bus and five single pane windows not covered. The bus is dry as a bone inside all winter.

Any ideas or thoughts would be greatly appreciated.

Thanks

The MCI 8 I had only A VERY COMPRESSED AND NOT VERY EFFICIENT fiberglass insulation in the roof..I would suggest removing the panels using foam board insulation sealed with canned spray foam ....reinstall panels and do as you will...it is a good easy investment now,would be difficult later...

Hi Grant,

Our ceiling was removed, then we used a layer of reflectix on each side of the styrofoam to double the r value and reduce sound and thermal transfer, works excellent!  The prior insulation in the ceiling wasn't as efficient as I would like to keep your bus comfortable from cold spots...etc.  It's actually not too much more work to remove the panels and address the insulation now, as later would be quite difficult.  Also, then you can see if there are any areas of concern, address any rust just starting....etc.  If you remain with the existing ceiling, you can use this reflectix in one layer for in-between.

Hope this helps,

Chad

Thanks, unfortunately the ceiling panels cannot come down at this point. So I am looking only to add something between the tin panel and the original equipment.

Thanks

Grant,

Abandon the tin and go with the foam (tin look) ceiling.

You will get a little insulation and the look, also no squeaks.

I used this product with superb results and now, time tested.

Cliff,

Interesting. Were the panels flexible enough to install on the curved surface of your GM?

If so, I'm going to look at these for mine.

Got any photos you could post?

Thanks,

Bob,

They are very flexible, to be 100% sure for your need I would order one to test.

Here is a picture of them in the rear bedroom in our 4905:



I used tile mastic to adhere them.  Which was the recommendation of the vendor.
