The south windows

This picture shows two of the three windows that face south. The crew had taken the outer air form off the middle window in order to get their scaffold out of the dome. We closed it up from the outside with greenhouse plastic that could be removed and resealed easily. From the inside, all three openings were insulated with two inches of foam insulation. The combination of insulating the doors and the windows plus the wood stove kept the inside of the come comfortable so we could work through the winter.
