Hard Top Foam Insulation

[m15256]

Awhile ago someone commented on replacing the original insulation with foam. I've done a fair amount of foam in building construction. I imagined drilling a number of holes in the liner and spraying through those. Then plugging the holes. But I wonder if someone has come up with a better method.
Thanks for any input.

This is the material used in CDN hardtops. A couple of sheets of this, painted to match your choice of colour...

Some CDN hardtops have the sheet metal interior like US trucks and many have the foam sheeting on the ceiling and rear walls around the sliding window. I have some of each on my trucks...

I am a long way from putting my hard top back together, but I have thought that since the "headliner" is steel why not put just the foam insulation boarding that you can get at Home Despot or Lowers and adhere them to the outer body and then put the "headliner" back in. But as I said I'm a long long way from that.

Depending how you want to finish it, as long as what you use won't collect and retain moisture it will be better than the original fibreglass type. I have a couple of trucks with the sheet metal liner and find they are noisy compared to the original dense foam material. Having said that, its not that an M37 is really quiet anyway but more so than original. The stick on stuff that I posted the link for looks like it would give the acoustic decoupling similar to other commercially available products. I have used 'Ensolite' type dense foam for sound deadening material on a marine project. I found that it did not absorb and retain moisture. A nice durable headliner material could go over whatever you choose. For me, the price is always a consideration. If not for you, the aerospace industry has some amazing insulation materials available. I wondered about a closed cell spray foam but getting the thickness uniform would be difficult. I may try that yet and put the sheet metal back after shaving it down.
