Draughts and Cold Spots If cold air seeps in around the edges of the glass or through the window frame, the rubber gaskets or seals have degraded or diminished. 3. Sagging or Misaligned Openings Gradually, the weight of the glass can trigger the sash to drop, making the window tough to open, close, or lock appropriately. This is normally a concern with hinges, tracks, or the need for "toe-and-heel" re-glazing. 4. Broken or Cracked Glass Impact damage, thermal stress, or structural movement can break the glass. Unlike single-pane glass, a broken double-glazed pane jeopardizes the entire unit's thermal efficiency and safety. 5.
