Thermopane Lives!
My first thermopane birth - click to enlarge
I got my first thermopane window done. My technique needs work. It’s been so long since I’ve done any glass cutting I wasted a bit of glass getting my skills back.
I don’t think the vinyl is going to be ideal as a divider. The butyl rubber mastic doesn’t appear to stick to it well enough. The end result certainly LOOKS like a thermopane window. To be on the safe side I’m going to make sure I’ve got good pressure on both sides at all the strategic points.
