We are an Andersen Windows reseller for the simple reason we believe Andersen manufactures the best windows and patio doors in the business.
A classic window style and very popular in the Milwaukee area and throughout Southeastern Wisconsin, a double-hung window has two sashes (a top and bottom) that both slide up/down to open and close, and tilt in for easy cleaning. A single-hung window is very similar in design and appearance to the double-hung, but only the bottom sash opens while the top sash is stationary.
