The last and largest window was installed on the River House today. It is 13 feet wide by 8 feet tall with a 4-foot sliding section. If I had to guess, I would say the triple pane unit weighs close to 800 pounds. Much of the morning was spent repairing a corner that was damaged in the last attempt at installation. I was skeptical that it would be done to my satisfaction but was pleasantly surprised by the quality of workmanship. The house is now fully enclosed. The front door assembly is the last opening to fill and will remain boarded until we finalize a decision and await delivery.
