Rolling Steel Doors

Installing Brush Weatherseal for Rolling Steel Doors

Rolling Steel Door
  1. Header Seal: Measure between the lintel and the door when the door is closed. Be sure to account for surface irregularities and wind deflection. (You’ll want to know the largest gap size.) Note that rolling steel doors may have a larger gap in the center due to door sag. For large commercial-type doors with gaps up to 3 inches, use larger brushes. For residential or smaller doors, use smaller brushes.
  2. Jamb Seal: Measure between the jamb and the door, taking into account surface irregularities and wind deflection. Rolling steel doors ride between two sections of angled steel. Angled holders mounted on inside jambs allow brush to seal edges of the door while preventing potential impact damage. Heavy-duty double-backed tape can be used for easy mounting. Our brush seals ship with screws for installation. (We do not provide double backed tape.)
  3. Bottom Seal: Measure the distance between door bottom and floor, taking into account floor irregularities- you want to use a brush that will cover the largest gap. For commercial-type doors with a 1 to 3 inch gap, use longer brushes. For residential or smaller doors, use smaller brushes.
