Q: I need two 18". Do you have more?

Update: At the time this question was asked, I had decided to stop selling the 18" domes because of the cost involved in shipping and storage. However, due to customer demand, I have decided to relist, taking those costs into account. If I am able to sell at a decent rate, then I will continue to have the 18" domes available.

Q: Hi Looking for a dome that is 10 inches in depth and 10 inches in width. Do you have any like that?

I'm afraid I do not. All of my domes are half as deep as they are wide.

Q: I'm thinking of using a dome for a door window in the trailer camper that I'm building. What do you think?

I think it could possibly work, but there are plenty of things you would want to take into account. One of the main things you want to make sure of is that you had a nice tight seal. Another thing is that it would not provide as good of insulation as a double-pane window, but it may provide better insulation than a single pane window. You'll also want to take into account that acrylic can get small scratches fairly easily, although these may be able to be buffed out with the right equipment. There are most likely other things to be taken into account, but those are at least some quick things to think about. The one time I used these domes myself was for 3 windows in a play fort, and it worked nicely for that.

Q: Can i stack two inside each other to within an 1/8 inch to crest a thermal break?

You would get a thermal edge with inside the dome, since they are the exact same size and do not stack flat against each other. However the outer flat mounting ridges, would have some separation.
