headroom - Vertical clear space required inside above the door opening, and below the lowest ceiling obstruction, required for proper operation of the garage door system. See backroom for additional information.

horizontal track - The portion of the track which is typically reinforced with angle iron to support the garage door when in the open position and is fastenened to the ceiling.
insulation - A material used to reduce or prevent the transmission of heat or cold or sound.
jamb seal - Weather-strip attached to the door jambs to help keep out wind and rain.
jambs - The upright piece or post that forms the side of the opening, which is usually wood, but can also be steel or block.
