ROOF INSULATION

[48ply1stcar]

I wanted to insulate the roof of the car and have been thinking about it for along time.  Today I used a Frost King water heater blanket 48x75 to accomplish the task.  So far I have glued it in place with adhesive and that is being held up by the bow.  Hopefully  it will stay in place when I remove the bows to put them in the headliner.  I sprayed the insulation and then used the bows to it stretch out and hold it in place.  

Wish me luck.

That's a great idea.  Curious to see how big of a difference it makes on hot days.

Too, much insulation, didn't stay up, too thick.  Starting over.

Also trying to come up with effective grommet replacement. Any suggestions for grommets.

I saw a nice selection of grommets at Lowe's last week.

[Young Ed]

I think someone way back on the forum used tire valve stems

[bobostski]

I got grommets from the plumbing dept at the hardware store.

Guess you'll have to pop for the proper light weight insulation.

I didn't say so, but was hoping it would work for you.  I replaced the headliner in my 72 Dodge Coronet years ago (previous owner chain smoker damage), and the insulation was deteriorated, so I glued that stiff type of fiberglass furnace insulation up there.  It stuck until after I had the headliner up, then began to sag.  I never took the headliner back down to fix it, but it always bugged me that it had done that.  It might have done better if it had been all in one piece, but I had used scraps.

When I removed the headliner there was a paper backed wool insulation glued to the roof.  I'm going to try again with something thinner.  Also I didn't clean or prep the bare roof.  i might try a thin foam for insulation.

I'm working on my 53 suburban roof. At ACE I found a harsh Brillo pad grille cleaner with a handle attached. I cleaned the underside with that by using soap and water by reaching through the windows. Then I sprayed on. LPS 3  rust inhibitor from LPS Labs on to neutralize what rust remained. Next, an adhesive backed product similar to Dura Max type product. fWIW.

 

in my opinion, that underside needs to be clean.

   Whatever you do you, don’t used anything styrofoam-based. Deadly fumes in case of fire.

Now you tell me!  Where were you four years ago, i may have been able to catch the cat! 

[DrDoctor]

pflaming,

   Sorry, but you lost me there, friend . . .  what cat???

Tonight I lined the roof with 80/20 Cotton/Poly quilt batting.  The batting is for Queen size quilts 90x108.( Wish I had gotten King size.  Glued and and folded lengthwise. After I scrapped and vacuumed the roof I glued in the batting again using the bows to keep the batting in place.  Also, I used more glue and smoothed out the batting with my hands.

Also went to Fastenal and ordered grommets.

What about foil-backed bubble insulation?  Surely that's light enough to hold up there using the bows & some adhesive.  Might even be able to do two layers.

3M 90 spray adhesive available at HD. I think the foil backed bubble insulation will deteriorate over a short time. It is used for pool covers to heat the water and will burst if  left in the sun w/o being cooled by the water. I used it to insulate the inside of my swamp cooler and after a season it was two layers of foil with shredded plastic in between.

[48ply1stcar]

Thanks for that info Soup.  I forgot about that product or I might have used it.

I used synthetic jute type carpet padding and adhered it using spray contact cement on one of my darts. It stuck and has not fallen in over 16 years. I was mainly interested in sound deadening and not insulation.  If I were to do this again I would probably use the stuff like you found...

[Hubler13f]

Here is what I did today. I had a 4'x6' piece of 3/8" thick Stainmaster carpet padding that I picked up from the flooring scraps at Lowes. After lightly sanding the ceiling I used the 3M 90 adhesive and sprayed the ceiling and let it tack up. I then cut strips and sections of the carpet padding and sprayed them with the adhesive on the plastic label side and allowed it to tack up. Then I cut and pieced and stuck the padding to the ceiling as needed. I had tried spraying the padding on the foam side but it didn't adhere as well. I also tried sticking it as one large piece but again no luck so I cut it into smaller sections.

13F was my MOS designator or job description in the army, a 13F is a Fire Support Specialist or Forward Observer also known as a Fister, In the end my full identifier was 13F4OL7

[48ply1stcar]

I thought it was something like that.  I retired as a MP First Sergeant in 1990.

[Hubler13f]

Thank You for your service, I didn't make it that far, I made the list for Sergeant First Class in 7.5 years and got pinned at a little over 8 years. When I got home from my 3rd deployment I ended up having 4 seizures and a bunch of other issues and they diagnosed me with a Traumatic Brain Injury so they permanently retired me at 11 years 4 months in 2011.

I used some of the bubble wrap on the roof, along with the roof insulation I saved from a Mustang, and a Mercury.      I attached these with windshield urethane.

I used a quality blanked for my headliner.     The blanked has two layers back to back, with seams about every two or three inches, easy for installing the bows...
