    What are you guys using to insulate the roof?

    I took off the headliner and did remove the original cardboard stuff insulation...it fell to pieces and it was a mess...I got it all out...seems like the put it on the roof and then welded the braces in place...weird..

    Anyway...I was thinking about some aluminum backed butyl (you US guys use dynamat for that).

    But I am afraid that it may come loose in the heat...especially with that black vinyl top

    Here’s mine before I installed the headliner. Couple ideas of what different things look like. First picture is the inside cleaned and painted with POR15. second picture has black Noico sound deadener stuck to the roof. If you look close you can see a waffle pattern. Third picture I put a layer of 1/8” thick dynamat dynaliner foam instead of the jute material before putting the headliner back up.

    I use regular house insulation. You can usually get it for free where they are remodeling a house from the dumpster. IF it's wet let it sit in the sun a few days until it dries out. Fit in place as nec. then glue the insulation & stick it to the roof. Once installed the headliner will hold it in place permanently.

    Thanks for the pics...just realised mine is missing those white plastic clips. Guess they hold the bows in place.

    I thought about house insulation as well...but those air bubble insulation you can get..they are backed with aluminum as well

    Got more thinking on your post, I would go with the 1/2" on the roof and 1/8" on the doors. Tha material is not that expensive.

    Thanks! I've used three rolls of the 1/4" and one of the 1/8" in the car....If memory serves me correct, I used the 1/4" on the roof and then put some on the cardboard trunk divider instead of the jute and patched the remainder around on the floor under the seat area. I used the 1/8" thinner stuff on top of the rear package tray area instead of the jute and then put the remainder around on top of they dynamat on the floor where you put your feet.

    Bought the Dynamat and Dynaliner from Amazon not too bad in price

    The Dynamat 1/8" I think would be a better option on my 68 Corvette project for the doors. I never cared for the thin plastic and paper used as vapor barrier.
