Benefits of Sectional Garage Door

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.

How Does a Sectional Garage Door Work

The operation of a sectional garage door is rather simple. When the door is closed, the panels sit one on top of the other, forming a tight seal. When the garage door is opened, the panels slide up and back along the tracks to the ceiling of the garage.

The door is operated by a motor that is connected to a chain or belt that pulls the door open and closed. Most sectional garage doors will come with remote control, which allows the user to operate the door from inside their vehicle.

Materials Used for Sectional Garage Door

Sectional garage doors are available in a wide variety of materials, including steel, aluminium, wood, and vinyl. Here at JDUK, we use high-quality galvanised steel for extra durability. Our doors are available in a wide variety of colours and finishes, ensuring there is an option for any project.

Components of Sectional Garage Door

01/

Panels
The panels are the most visible part of the door and can be made from various materials, including steel, aluminium, wood, and composite materials. Each panel is connected to the next by hinges, allowing them to bend and follow the tracks.

02/

Tracks
Sectional garage doors operate on a system of vertical and horizontal tracks. The vertical tracks guide the door upwards, while the horizontal tracks help the door move along the ceiling. This track system enables smooth and efficient operation.

03/

Hinges
Hinges are crucial components that connect the individual panels. They allow the panels to pivot and follow the curvature of the tracks, ensuring the door can open and close seamlessly.

04/

Rollers
Rollers are attached to the sides of each panel and run along the tracks. They facilitate the smooth movement of the door, reducing friction and wear on the tracks and panels.

05/

Springs
Springs are essential for counterbalancing the weight of the door, making it easier to open and close. There are two main types of springs used in sectional garage doors: torsion springs and extension springs. Torsion springs are mounted above the door and provide a controlled lifting force, while extension springs are located on either side of the door and stretch to provide lifting power.

06/

Cables and Drums
Cables and drums work in conjunction with the springs to lift and lower the door. Cables are attached to the bottom of the door and wind around drums when the door is opened, helping to distribute the door's weight evenly.

How Do Sectional Garage Door Operate

Initiating Movement
When you press the remote control or wall switch, the garage door opener activates, triggering the movement of the door. The opener is connected to the door via a motorised mechanism that pulls or pushes the door along the tracks.

Lifting the Door
As the door starts to lift, the rollers move along the vertical tracks. The hinges between the panels allow them to bend and follow the curve of the tracks smoothly. The springs provide the necessary counterbalance to the door’s weight, reducing the effort needed to lift it.

Transition to Horizontal Movement

Once the door reaches the top of the vertical tracks, it transitions to the horizontal tracks along the ceiling. The rollers continue to guide the door, and the panels straighten out, laying flat against the ceiling.

Full Open Position

In the fully open position, the door lies parallel to the ceiling, leaving the garage entrance unobstructed. This space-saving design is especially beneficial for garages with limited headroom or short driveways.

Closing the Door

When closing the door, the process is reversed. The motorised mechanism guides the door back along the horizontal tracks and down the vertical tracks. The springs and cables work together to control the descent, ensuring a smooth and safe operation.

FAQ

Q: What is a Sectional Garage Door?

A: Sectional garage doors consist of between four to six separate horizontal panels, which rise vertically before sliding horizontally back into the garage along ceiling runners. When the door is open, the panels sit within the garage roof space. The panels are typically made from galvanised steel and filled with insulating foam to keep the garage warm and dry.

Q: Which Sectional Garage Door is Best?

A: For those on a budget, single-skinned sectional panels are generally more affordable, as they don’t have added insulation. Meanwhile, premium designs tend to feature double-skinned panels which are filled with foam insulation. These are a good choice when the garage is in regular use as a workshop or additional room, or when the contents of the garage need to be protected from varying temperatures.

Q: How Long Does It Take to Install a Sectional Garage Door?

A: The installation of a sectional garage door takes between four and six hours. This can vary depending on the type of existing door that is being removed and whether the new door is being automated.

Q: How Much Headroom Do You Need for a Sectional Garage Door?

A: When installing a sectional garage door, between 100 and 220mm of headroom is generally required to accommodate the ceiling runners which hold the retracted panels when the door is open. In comparison, a roller door typically requires around 300mm of headroom, so a sectional door is a good choice where ceiling height is limited, or you need to maximise drive-through height.

Q: Can You Put a Door in a Sectional Garage Door?

A: Some sectional garage door designs feature a wicket door, or pedestrian door, which is a doorway in the garage door that can be opened independently. Offering easy access to and from the garage without opening the full door, this is handy if you enter your home through the garage or it is used as a passageway between the rear and front of the house. This smaller doorway is also useful when bringing out bikes or lawnmowers.
