When it comes to potential storm damage, the bigger the window or exterior door, the greater the risk it poses.  Should a large pane shatter, personal injury, water intrusion and, worst of all, roof failure may occur as a result of dramatically increased wind loads.  Broad glazed areas are difficult to protect with shutters and boards.  For these reasons, Bildau & Bussmann, have concentrated their efforts on designing and testing large and vulnerable units like double entry doors, French doors, sliding doors and fixed and operable window systems to the largest spans possible.  Approved size ranges are impressive:

  • Entry and French doors to 86″ x 120″
  • Lift & Slide (XOX) to 220″ x 120″
  • French Windows to 78″ x 96″
  • Single Windows to 41″ x 96″
  • Fixed Sash and Direct Set Picture Windows to a huge 90″ x 120″
