I am not certain to be honest. They have three versions, the top of the line, and then one just below it, and then a version that is similar to the windows you find at home depot. We got the just below top of the line (only difference is the locks aren’t quite as strong, and the lift bar isn’t as big)
Installation is certainly included. They did a really good job, and cleaned up everything so it was spotless before they left. I would highly recommend.
