I appreciate all the work you've done to bring us along as you have created this labor of love. Someone asked about your windows a while back. Just for reference I have them in my home here. In Canada they are made by
EuroLine - Home and are amazing. Also by the way you hit the slutty out of the park they fit right in. Solid enough that they may pass as iso doors.
All the best as you sort out your problems. Bummer the designer hasn't stepped up. Doesn't speak well for their pride in performance. How does the tracking room sound in comparison?
