I could never deal with Florian again, Ursula. After numerous contacts over a two-month period, by me, my installer, and my contractor, Florian would not communicate whatsoever. No returned phone calls and no email responses. Once the solarium was built, the company had absolutely no interest in answering questions or replying to concerns. They had their money (plenty) and that was that.
I am sure, if I find it necessary, I can purchase a motorized shade-cover and have my installer put it up. I assume Aluminet has something available in that regard, though I have never used that product.
