What type of insulation ?

[Airwave503]

Alis, Your Lizzard skin approach is probably pretty good. I didn't find a need for any adhesive because I cut my pieces to fit snug so they held each other in place, even in the rounded end cap. Then I went over the seams with foil tape for the full vapor barrier.

Depending on how thick the Lizzard Skin is you should probably be able to go with the 1" throughout.

lizard skin is 1 or 2mm when dried, I forgot its been 5 years since i used it. alot of people tried to mix latex paint with ceramic spheres, but sometimes ya just got to bite the bullet and go with the real deal.

I have a 1989 square stream, when A.S. bilt it they shot the inside of skin with ureathane.
The stuff is as good as the day it was guned on, look into haveing it shot by a pro Copany

Great thread: I'm at a similar junction with a '65 and there is something
about plastic bubbles in an area that might well get over 100 degrees
that just rubs me the wrong way. BIG fan of Prodex spacers for minimal outer
shell contact and air barrier.

Slightly off topic but I'm at the same stage in my restoration. Getting ready to do a combination of prodex and fiberglass. I've been concerned about applying a sealer to the inside of the exterior skin before putting the insulation in. Perhaps something similar to lizard skin. Is there a thread about sealers to use to replace the tar like substance that was originally used on mine?

Hi,

I've stopped my choice.

Many possibilities and each person thinks different, few insulate material are better than other and some different prices etc....

I choose rockwool in 45mm (the same as the beginning...), why ? Because :

It's easy to remove,
It isn't very expensive
it looks like the same as he original brand (fiberglass)

I begin this weekend by the door

I was just speaking with Roxil yesterday. They also have a commercial product called "Acoustic Fire Batt" which is the same product, but comes in a variety of thicknesses in 1/2" increments including 1.5, 2, and 2.5" priced comparatively to the regular batts. That way you don't have to split the regular batts to get the thickness you need.
Cheers,
Jack
