Insulation discussion

Post by kstills »

Are you putting the same kind of insulation back in or going with something else? I'm reading that wool is a good choice for van builds because it doesn't hold moisture or some such.

Huh, I've heard that wool is good for keeping you warm even when it's wet. I haven't really thought much about it yet, but I was probably just going to use regular fiberglass insulation.

Interesting. It's somewhat more expensive - this stuff works out to just under $100 for the same 100 sq ft that is $150 of the wool. But the difference might be worth it.

The unfaced fiberglass is a good bet, but the wool will have better sound insulating qualities at the same thickness. I wouldn't use it in a house because of the cost, but for the amount I'll be putting in the van I think it's a bit better and worth the extra cost. But I also may be talking my self into using it, lol, because there really isn't that much difference between the two.

Just came across this bit. Fiberglass insulation loses R value dramatically as the humidity increases, which if I'm reading the specs on the wool insulation correctly, it does not (up to 65%). I think that is why the wool would be a significantly better insulator than the fiberglass for these builds.

This website DOES NOT recommend using fiberglass batting for insulation. Reading their rationale for the use/non use of other products, they do seem to know what they're talking about wrt insulation methods (IE not using reflectix attached to the van walls etc), so I think they're correct in what they're saying.

Thanks. Maybe I will go with the wool. I hadn't even thought about using the expanding foam to fill in gaps, too, but I'll need to do that.

I've always been a little suspicious of the reflectix - and that article confirmed my thoughts. We have some that we use in the rear window of the trailer (for example) to provide extra insulation. But I would never use it in a wall.
