I thought this was an interesting question. IÂll post some thoughts in the hopes it will spark comments from others. I found one thread that mentions frosted glass being used in a conservatory: Opinions on Frosted Glass? Frosted glass does diffuse the light, and diffused light is beneficial. In spite of that, I couldnÂt find much information on the Internet regarding the use of frosted or etched glass in greenhouses. So, my guess (just a guess) is that frosted or etched glass is not widely discussed as an option for glass greenhouses because it doesnÂt negate the need for shadecloth or whitewash in sunny situations. If it provided a definite advantage over clear glass, it seems like it would be easier to find more references to its use. I donÂt see why it would be too opaque. Maybe itÂs not discussed much because the people who choose glass greenhouses also enjoy seeing in or out; if they didnÂt care about that, they might as well choose polycarbonate. That being said, I think you have a good reason to work with this idea. If it helps you transform recycled windows into something that pleases you when you look up at themÂinstead of being annoyed by streaksÂthen why not? The only downside I can see is you might find you still have to do something additional to diffuse the sun coming into your structure. (I wish I had the experience to wager a guess about that, but I sure donÂt.) IÂd be tempted to try one window (or a scrap piece of glass) to see if I liked the results. Now, if itÂs a double paned window, and you frosted both pieces of glassÂwould that diffuse the light even more? I donÂt know... Maybe someone that knows more about light diffusion than I do will pipe in here.

Hi guys...thanks for your answers... I guess it will be hard to predict the outcome because the tree has not been without it's problems The tree was spaded in 6 years ago with 6 other large trees which have all done very well. They were large caliper...maybe 8" +..they used the largest spade they had. The tree started to lose branches after the first year it was spaded in. I read up on it noticed that it looked alot like chlorosis (leaves looked sparse, small, yellow). We have very hard water here and pin oaks are really prone to this. So, we bought some iron injectable capsules from an arborist supply company and have had to drill the tree every 3 years...a PITA but worth it as the leaves get nice and green. We have not lost a branch on 2 years. The tree grows slowly though. It is probably 15 years old. This tree is usually the last to leaf out...man I hate unpredictacle weather :( I guess I will have to wait and see. I would sure hate to lose it though...

There is no need nor desire to seal glass tile of any sort. Do use a NON sanded grout if using a cement based grout. Better yet, use Fusion Pro or Flexcolor CQ. While both are sanded, they are painted sand and not the scratchy angular sand found in cement based grouts. Do not use Spectralock with frosted glass as you can't wipe the residue away on frosted glass.

Well... we have the 36" two door uppers. LOVE THEM! We've only been in here with them a few months and just moved our stuff in so right now they are holding a boatload of crap till we get shelves elsewhere and can organize. They are somewhat translucent but all you can really see are some shapes. You can see some muted color on things like my wine glasses which have colbalt blue glass stems. I'm thinking that when things are spread out and as they should be in there; that'll it'll look pretty. OH... we were going to get the horizontals (I wanted them) but DH REALLY felt the others would hold so much more for us. I went with him on this one since I otherwise got everything I wanted... and he ended up being right for us.
