Shortcommings of our products
I would like to challange us to discuss the shortcommings of our products. Not because any one manufacturer is any better than any other...but because if we don't know, recognize and address the shortcommings...some else will, and that's what is happening to fiberglass now.

So....lets grab something and hash it out.

Just for a teaser lets start with this one.

We accept Closed cell foam as a vapor barrier. Rightfully, when the perm test is below one, by code definition, it is a vapor barrier.

But as time passes, 245 leaks from the cells and is replaced by what? And does the perm rasting remain the same? and what does this mean?
