Will my sash windows reliably open and close for years to come?
In older windows, the cords fitted to weights in the side jamb of sash windows can deteriorate and break, causing windows to stick. Timbertherm use a spring loaded contemporary balance mechanism in their designs that is concealed to the naked eye and far more durable than traditional balance tubes or weighted cords and pulleys.
