Sectional ­ Robust, secure and convenient

∙ Sectional doors are usually constructed of three to eight panels and slide up and

overhead.

∙ Sectional doors occupy exactly the same amount of internal garage space as a up and

over door.

∙ Sectional doors do not require any space outside the garage to open. A vehicle may park

very close to the garage before opening the door.

∙ Each panel of a sectional door has its own connection to the door track. This increases

reliability and robustness compared to monolithic doors, which have only a few track

connections for the whole panel.

∙ Garage doors can be made out of many materials, but steel, aluminum, wood, copper,

glass and vinyl (polyethylene) are the most popular materials. Some manufacturers

incorporate foamed­in­place polyurethane insulation within the sectional garage doors.
