Installing new sash runner or spring bronze could be required in the event that a gap blocks windows from opening and shutting smoothly. These are a type of bronze that are stapled or nailed into the edges of the lower sash to prevent sideways rattle. They are available at DIY stores. Tubular weatherstripping also can be used, but it is more likely to tear and can alter the appearance of your Double Glaze Window repair.
