[Greenbuilding] Fiberglass manufacturing process.

[Bruce Donelson]

We've never claimed the fiberglass was a perfect material for windows.
In my view anyone who believes otherwise is delusional.

Hi Stephen:
What do you see are the major drawbacks to fiberglass, and is there much
chance that any of these can be lessened any time soon?
