Advantages to Double-hung windows with Pulley Systems.

•  It opens vertically so no one walking past will have to worry about whacking their head on it. 
•  It stays open without the need for locks or clasps.

Disadvantages to Double-hung windows with Pulley Systems.

• They brake. i.e. ropes snap, wheels can get brittle and fall apart.
• The windows aren’t sealed so cold draughts can get in which is not good during the winter months.
• In todays age they are difficult and expensive to fix and maintain.
• The window frame has to be pulled apart to fix pulley wheels and attach ropes back onto the counter weights. So would possibly need new wood for the frame and paint when putting it back together.
• Repainting windows has to be done carefully if doing it without pulling the frame apart to make sure they don’t get painted shut.
