What is a sectional garage door?

A sectional garage door is a type of garage door where the door panel is split into sections horizontally, and opens by rising vertically, sliding in tracks which then curve and then travel horizontally into the garage. This then leaves the entire door resting parallel with the ceiling, usually higher up than the door ordering height.


Space saving

Sectional doors open vertically and are suspended under the ceiling, meaning that the space outside and inside of the garage can be utilised.

Variable fitting

The shape of the opening is not important when the door itself does not pass through the opening, meaning sectional doors are ideal for arched, angled or odd shaped openings.

Wider passage

The design of the sectional door gives maximum drive through width and height when open unlike other garage doors.

Sealed All Round

Flexible, weather resistant seals on all 4 sides keep out the wind, rain and dust.

The thread of images below show how the sectional door simply rises horizontally, slides along the tracking and sits just below the ceiling for ease of operation, as well as optimising space.

How Operation Works & Sealing

In comparison to the Up & Over door, traditionally popular in the UK, sectional doors are generally easier to open as the operating function is quite different as the spring mechanisms give assistance nearly all the way through the opening cycle.

The sectional door is assisted in operation by using either torsion or tension springs situated either at the sides or above the door. Hormann offer both types and the use is dependant upon the overall weight of the door panels used.Sectional door benefits short driveways

On most standard height domestic sectional garage doors, the overall door is split into 4 panels and they are available up to 5500mm wide. On heights over 2250mm the door will have 5 panels and so on up to 3000mm.

Due to the operation of sectional doors, they can be fitted into garage openings that may be slightly too small in width or height for a standard size door. This also means that all the standard rubber weatherseals fitted around the perimeter of the frame work very effectively when the door is closed. The bottom edge seal is quite large and is very effective on a smooth concrete floor for sealing against dust, leaves, mice, etc.

Most sectional garage doors sold are double skinned steel with an insulating foam infill inbetween the steel sections creating a tough, insulated panel. This provides excellent thermal insulating values as well as great security and resistance to knocks and bangs, quite unlike single skinned doors.

Each door section also has a patented anti finger trap protection with a further rubber seal built into the section at the top of the panel, ensuring a good seal between the horizontal sections.

Sectionals with Pedestrian Doors

Sectional garage doors can also be supplied with a seperate pedestrian door built into the main door for garages where frequent access is required on foot.

This pedestrian door option is available in doors up to 4000mm wide and 3000mm high.
