I decided to upgrade 16 of my two-pane windows to triple-pane with tint for the sunny-facing windows. I also replaced one door, and the difference has been remarkable. It's quieter in the house, and best of all, the door fits perfectlyI can no longer see daylight around the edges. Although I was a bit indecisive about the type of frames for inside of the house, I ultimately chose the thick, flat wood frames over the plastic-all-in-never-have-to-paint. While the project wasn't dust-free, the sales agent, installation crew, and office staff were all fantastic. These windows are excellent, and with a 25-year transferable guarantee for the house, you can't go wrong.
