Sash Balancing Options
|
Balancing your windows is important if you intend for them to operate. Proper balancing enables the sash to stay where you place it, throughout it's vertical travel. With balanced sash, you can throw away the sticks you've been using to prop open the window. |
As with all other aspects of a repair/restore/preserve/improve project such as we're contemplating, there are pros and cons with every option. The advantages of the ropes and pulleys are that a) it's probably the easiest system to re-install after removing the sash and b) it's certainly the most original/historic. But, believe it or not, there are some downsides as well and it's debatable which are the most onerous. For one thing, many people who are undertaking a project of this scope do so with the intention of enhancing the thermal efficiency of the units and they feel the hollow balance cavity is a significant factor in heat loss and drafts (feel the wind blow through the pulley mortises?). That premise is itself is under debate amongst the professionals. |

This style of balance has been used successfully for at least one hundred years. It is exactly like a tape measure in its function. We have found these still operational in a few window projects we've encountered. |
These are our favorite balance method for several reasons. |
