Some windows combine three functions in one. That is, they perform as ordinary glazed windows but they also have permanent storm and screen sections that can be slid into place in season. Typically framed in aluminum, combination windows have three channels running along each side of the frame to hold two glass sashes and one screen sash. The three channels are staggered to make three openings of slightly different sizes, each of the three sashes thus fits in one and only one of the channels.

When working on any part of a combination window, it is generally most convenient to remove it from the frame. Examine the mechanism carefully to remove a sash. There are usually tabs located along the channels or on the horizontal sashes that can be pulled out to release the sashes from the slides that hold them. Squirt window cleaner around the tabs if they prove difficult to release and scrub with a toothbrush to loosen and remove the grit. Pry the tabs gently with a screwdriver if needed but don’t bang on the frame because old aluminum can be brittle. Once the tabs are free, raise the sash a few inches and pull the bottom of the sash toward you. Carefully twist the window until one of the guides at the top of the sash is disengages from its channel. Now lift the sash out of the window to work on it.
