The installation went smoothly. The workers showed up early and got to work immediately. They took out a window, cleaned the site, installed the new window. The windows in the three bathrooms, the kitchen, the den, the enclosed porch, the study, and, the master bedroom were replaced by the end of the first day. The windows in the living room, dining room, sewing room, and one bedroom were replaced the second day. The bathroom window are frosted, so they let in light, but provide privacy. The windows were made according to the specific measurements for each area and group of windows. My home has so much more natural light in all the rooms. It is also quieter inside. My daughter and I are pleased with the look of the new windows, and the improved visibility. We are curious about changes to our utility bill. We are very happy with outcome.
