Thanks for the responses guys. As of yet they haven't called for an actual quote, although we did msg back and forth a bit to determine exactly what they were made of, the plexi type hard stuff or the saran wrap. They are saran type vinyl, which honestly I agree with you Samuel, not something I'm too keen on.
I now remember having those on my patio, back when I had a condo about 15 years ago and they were always trying to split apart along the edges. I've done a lot of research about various restoration of marine/airplane/auto vinyl and plexi type windows though from this and gained some good information Always learning!
