In the sixties aluminium framed windows became popular and supplanted the old wooden types in popular architecture. Presently the latest technique is to use vinyl frames. These frames are specially designed to hold insulating double paned glass for saving energy. Of course these new technologies can be used in older homes with the wooden frame glass assemblies. When used though, the look and feel of the home is changed into a half historic half modern look. To preserve that older look many owners are doing sash window refurbishment rather than vinyl replacement and updating.
Inside these wood framed panes, and inside the casing are two iron counter weights. These weights are attached to a rope that runs through a pulley which you should see at the top of the casement in the channel the framework runs up and down in. If it is a working window you should see the rope in the middle of the channel.
Over time this rope breaks as it wears through with use. When that happens the weight drops inside the casement and the window is immovable. If the other weight is still attached the frame will jam when you try to open it. Frequently both ropes are missing on these types of assembly, presumably because the user wants to open the window and hopes if the odd weight out is cut off as well the frame will not jam.
After the ropes break the window is only opened with great difficulty. Sometimes they are painted over and over and eventually welded shut with all the paint.
Fixing a sash can be easy provided it has not been painted shut. These type of glass frames are enclosed in a outer frame or casing. On either side is a access port of sorts that can be opened to allow you to find the old weight and hopefully reattach the rope to the weight. If you look closely on either side you should be able to see the place where this access panel meets the casing. This can only be done with an open window.
If you replace the rope, which is a great idea, nylon will be a good choice as it doesn't wear. All rope stretches over time so be sure the length is right. The weight of a open frame should be about the bottom frame of the window opening. It should swing freely when the unit is all the way open.
The rope connects the weight to the moving wooden frame. This will mean the movable frame will need to be removed from its casing to reattach the rope. After you have pulled it free from the casing, check the side stile of the frame. Fittings suitable for tying the free end of the rope should be available.
Old fashioned windows with the proper materials and installation can be as efficient as the modern ubiquitous vinyl ones. Sash window refurbishment can retain the historic charm you home had in the past. With proper care some maintenance there is no reason these windows can not last as long as the newer models. This can be quite a job so working or consulting with a knowledgeable construction contractor with experience in older homes is recommended.
