Depending upon how big your cave is you might want to go with a spray foam insulation company. If you are doing a cave of any size its the only way to go. We have a 50 foot cave and have had it sprayed and re-sprayed several times. Just make sure that you get the foam that cures with a hard shell verses some of the foam that stays soft. The hard shell will help protect it and makes it feel like a cave. The fist time we sprayed we were only 25 feet long and we spent about $2200 bucks spraying it. If we had used the foampacks we would have been well over that. I do use the foam packs now just to fill in cracks and that type of stuff. Once sprayed and painted it looks cool!

There is a kit that runs about $650- that is the one that I get.
It covers a pretty good sized area.

You'll have to excuse Allen, he's probably out finding more monsters for his museum.

I'll post the video here for him (lol)


The kit I was thinking about trying (this is the 2nd place for me, I lost the original link / store that someone mentioned in another thread that I can't find in 2 minutes and gave up)


I believe this is his kit he's speaking about. He's not the only one to say to use this kit either! I WILL be trying this in the future.

The fire rating is on the data PDF. Middle left of the second page.
