3. An in-depth review of the advantages and
disadvantages of each door type
Retractable Doors
A large proportion of the door swings outwards as it opens and then
slides away into the ceiling of your garage, pivot points are located at
the top of the door, consequently you are unable to park too close to
the garage door.
These doors are fairly easy to install with spring assemblies being
fitted to the side frames and tracks to the top which support the top of
the door, the latter being secured a couple of meters into your
garage. They are however the easiest type of door to automate with
any electric opener being suitable.
Security is generally pretty good with manufacturers often fitting
four latches, but when automated these latches are disabled and the door
could possibly be forced open at the base depending on set-up, however, an
automatic de-latching system is available to counter this problem.
Retractable doors are generally available in all materials: Steel,
Timber, GRP and ABS. Pre-framed versions are available.
With this door type fitted you will have a fairly drafty garage and
drive-though width will be reduced because of the side spring
assemblies, although some manufacturers have an optional mechanism which
avoids this.
Some prices can be found on our Retractable and
Canopy Door pages.
Canopy Doors
The door swings outwards as it opens (but not so much as a retractable
door) it then slides upwards into the ceiling of your garage
leaving one-third of the door protruding outside the garage and taking
up less room inside. You are unable to park too close to the
garage door.
Pivot points are located two-thirds of the way down the door, which
helps improve the security of the door. Pre-framed versions are
available.
Canopy doors are the easy to install as the entire door mounts to the
door frame and no tracks are required inside the garage. The down
side is that automating a canopy door is not recommended - with the
exception of Cardale canopy doors which can be automated very well with
a specially designed Autoglide opener but it is a little more expensive
than normal electric openers.
Canopy doors are generally available in all materials: Steel, Timber,
GRP and ABS. With this door type fitted you will have a fairly drafty garage
although the drive though width will not be reduced beyond the door
frame.
Some prices can be found on our Retractable and
Canopy
Door pages.
Sectional Doors
Sectional doors (made up of several separate horizontally hinged panels) fit to the rear surface of the front brickwork of your
garage, and as such need a small amount of clear brickwork to the sides and top
of your opening. The entire door rises vertically upwards and then
backwards into the ceiling space. No door frame is required which
increases the available drive-through width.
Good security and good protection against the weather with sealing all around the door, doors
with or without insulation are available. Sectional doors are generally manufactured in steel although some specialist
timber versions are available.
Easy to automate as any motor is suitable - a soft start/soft stop opener
gives a real touch of class. Easy to fit as the doors come in kit form and
are assembled in approximately 4 hours.
More information can be found on our Sectional
Door pages.
Roller Doors
Roller doors are a single curtain that rolls up into your garage ceiling. They fit to the rear surface of the front brickwork of your garage, and as such need a small amount of clear brickwork to the sides and
between 450 and 205mm ceiling clearance above the underside of the lintel. The entire door rises vertically upwards and then rolls up on a spindle in the ceiling space.
No door frame is required which increases the available drive-through width.
Good security and good protection against the weather with sealing all around the door, doors with or without insulation are available.
Roller doors are either manufactured in Steel or Aluminium and are either single
sheet or hinged slat. Manual and electric versions are available.
Installation is straight-forward but two people may be required to lift the curtain onto
the support brackets in the ceiling of your garage.
More information can be found on our Roller Door pages.
Side Hinge Doors
A very traditional looking style of door that is
manufactured in timber, GRP or steel. Side hinge doors open outwards and
therefore need good clearance when being opened so not great if you have
a short driveway, a driveway that rises or a door that opens directly onto a public area. A good
choice if there is no clearance inside your garage to allow for an up
and over door.
Security is good if you have overlapping leaves and use bolts at the
top and bottom of the door. Automating this door is possible with the use of a Side Hinge
Converter that attaches each wing to the electric operator but security
is poor.
