Gordon, Plexiglass is an acrylic plastic. Plastics yellow when exposed to ultraviolet light unless protected by using a UV inhibitor in the manufactue of the product, however not all acrylics contain UV protection. You can't tell just from looking at it, you need information from the manufacturer. Even with protection, plastics may evntually visually degrade when exposed to weathering because they scrath easier than glass and even simple cleaning may eventually cause the material to become hazy due to scratches from windborne sand and dust as well as cleaning them. Personally, I would use glass.

@windowswashington - thanks for pointing out that keeping them open will decrease the risk. While obvious, I'd not thought of that. THANK YOU! @toddinmn - cannot "take the money." Need to either get them installed now or lose the opportunity for the insurance company to pay for their replacement. They will only pay - if they see them actually installed. The Jeld-Wen are double hung, so I can flip them inward to clean.

Valley, where DD lives, is still without power. She helped evacuate all the elderly people in the assisted living place she works, that's 1/2 blk from her house. Her and the kids had gone to Omaha to get something to eat for supper because she'd lost power. She came back, about 7:30 or 8:00 and saw the fire trucks and rescue squads there at Orchard Gardens and went to see what was up. Then she volunteered to help. She called me about 10:15 last night to come get the kids, and bring them here. They were so tired, and no lights at home. When she got done, about 12:30AM she came here too and crashed. Can you believe that assisted living place doesn't have a back up generator? I can't. They had lights for 2 hours, until the batteries went out. Those poor people had to go to relatives homes, if they had anyone that could come get them. They brought 8 of them up here to Fremont's care center. What really torks my jaws is the way people act like it's the staffs fault this happened, and beotch at the care takers because they had to "come get their parent when they have a house full of company".

I was rushing around earlier and didn't read all the comments. Heck and double heck on missing out on registering it as VS. Can you just add an "s" somewhere to the name? As in Valentine Sweethearts or Valentine's Sweetheart or maybe Valentine Day Sweetheart? ....... Please don't start it with an "s". My data base is overloaded with daylilies that start with an S, not many with a V though....I will continue to call it VS until further notice...........Maryl
