If your prime concern about purchasing a garage door is security then a sectional garage door is your door. What makes sectional garage doors so secure? Sectional garage doors are comprised of several lengthy panels. Each of these panels is made of two steel walls/sheets which are reinforced with large amounts of dense insulation. The manner in which each of these panels combines with interleaving edges further reinforces the door. Those who purchase a sectional door usually purchase an accompanying automatic garage door opener. Due to a sectional door’s construction and purpose, these doors are slightly heavier and can be more difficult to open.

These draught-proof doors not only keep out draughts, leaves, and dust but burglars too. While Up & Over doors are penetrable with merely a crowbar, such is not the case with a sectional counterpart. Sectional doors are usually mounted against the garage door opening wall as well as the ceiling. In addition, the door sits flush against the wall and floor when in the closed position making it difficult to leverage any tools upon the door.
