bit, thanks so much for that great information! My head hurts from trying to cram it in there, but I'll be fine in a day or two! I've read up on it before, but never quite figured the whole thing out. What you wrote made more sense than anything I've read in the past, so I appreciate you taking the time to explain it to me!
I do know that mine block 100%. One benefit is that the furniture doesn't fade, which is nice. Maybe the plant that I had, and that my neighbor had, required some UV. I'm not worried about it now since the next owner can worry about it instead. I do have a prism to check the spectrum with, but it's already packed away. It will be interesting to see what happens at the other house though!
