Things may have changed since then, but with all these "green" building materials coming out over the past few years, (i.e. wheatboard, sucrose-based insulation, etc.)I wonder if anyone has researched if they are indeed resistant to vermin and other animals or insects.

So in keeping with my new year's resolution, I will try my best to avoid specifying it.

We had a project many years ago where sea gulls had a liking for the multi-component polyurethane sealant used in paving joints. Whether or not it had food value, the gulls had a grand time pecking at the sealant.

Also - I had a senior partner in the firm I worked with back East observe birds pecking at the brick mortar joints on our office building. Nothing's safe.

I wonder if it melts when it gets wet? George A.

It seems the former is more probable, since sucrose would grow mold and be eaten by lots of things. If they want the product to be used, they should make this quite a bit clearer. Seems like another unfortunate way to divert agriculture from food production. We saw what happened with ethanol.
