We supply and fit Roller Garage Doors, So what Are Roller Garage Doors?
To put it simply – they are one of the most common styles of garage doors sold in the United Kingdom right now, and it’s easy to see why:
- Vertical opening and closing saving space on your driveway
- Very little internal intrusion into your garage
- All doors made to order maximising width and height
- Quiet when in operation
- Massive choice of finished colours and wood grain finishes
- May be fitted inside, in between or outside the garage opening.
- Very stable (with the necessary specification)
- Universally attractive with a crisp, unmistakable style
- Broad choice of access control methods for electrically controlled models
What Are The Main Differences Between Steel & Aluminium Roller Shutter Doors?
Do some research, and you will soon discover that roller shutters in the UK are only available in steel and aluminium (referred to as single skinned, double-skinned or insulated roller shutters by most manufacturers) so what are the key differences?
Steel Roller Garage Doors (Continuous Curtain Roller Doors)
The steel roller garage doors are made of large sections of single sheet steel, which are joined together approximately every 750 mm to create a complete continuous curtain, which is then connected to and rolled around a skeleton drum to produce a roller garage door.
Inside the skeleton drum, there is a part of a steel tube which has a spring wrapped around it and both are linked together so that the stress can be added to the spring to serve as a door balance adjustable depending on the size and weight of the door curtain. The steel tube stretches out each end of the roller and is used to secure the entire roller door to the steel brackets that are mounted to the inside of the garage frame.
The entire roller door is simple in nature and relatively light to operate, and when the door is required to be electrically powered, the simple motor device is easily bolted to one end of the roller door and controlled by the control box and remote control handsets as required. There are a few variations in the electric motors used, but all of them match externally at one end of the roll are often 24V and use the same form of sensing used in regular garage door operators where the motor unit can feel a voltage surge if the door is blocked and instantly stops and reverses. A wall-mounted control panel with built-in light, push-button control and radio control signal received from the transmitters is all fairly standard.
Aluminium Roller Doors (Insulated Roller Doors)
Almost all aluminium roller garage doors in the UK are made of single, double-skinned slats, typically with a foam-filled core, with an average thickness of about 19mm. Every aluminium slat is typically around 77mm deep, and all of them differ slightly in the front-facing design, some of which have a fully smooth surface, some of which have a thin line or two features in the design. The slat often has a curved form, allowing the curtain to roll efficiently.
The distinctions between this door and the steel roller garage door are very clear, but there are so many manufacturers in the UK that it is difficult to generalise. One of the main differences is that aluminium roller doors almost always use a tube motor system for electrical operation, and almost all doors are electrical, as it is difficult to manufacture a satisfactory manual version. There are two exceptions, and these are the Hormann Rollmatic, and Garador Gararoll, which are essentially almost the same door and both use an external motor mechanism. With a barrel-style motor system on any roller door, a minimum degree of protection is required, as the engines simply drive up or down under power and require other external equipment to control the movement.
The door curtain guides are normally between 60 and 100 mm wide and provide greater resistance to forced entry attempts and high winds.
The roller curtain size is smaller than the steel roller door as the individual rollers roll up tighter – a significant consideration for optimising the drive-through height when opened when the internal headroom is limited.
The curtain is thicker as the slats are double-skinned and foam-filled.
The process is smoother as the motor is worked within the roller and the tolerances between the curtain and the guides is smaller, minimising the risk of rattling in windy conditions.
The electric motor is operated as standard by means of a wall-mounted control box with built-in lighting, push-button controls and a receiver for hand-held radio transmitters with roll-code technology used in higher specification models.
The sealing at the bottom is often easier as aluminium roller doors have a higher degree of versatility in closing gaps on outer floor surfaces, as the slats have a slight movement between each one and an average height of 21 slats, which allows a lot of movement.
Generally, the strength, stability and protection of aluminium double-skinned roller doors are higher than any single skin-built door providing extra benefits all round.
Which Roller Doors Should You Consider Buying?
This is simple; just make sure that you only consider roller garage doors produced by reputable, well-established manufacturers complying with all applicable CE specifications for the UK market.
Most of the rates are very similar at the front end, and the discounts you will get can differ greatly, but the one thing you need to be sure is that the size, quality and installation is right.
Roller doors can seem easy but incorrectly mounted they will fail quickly as there are a lot of tension and moving parts and some doors can be more than 5 metres wide, a big moving object by any norm!
Beware of the recent influx of much cheaper aluminium roller doors into the UK market. All made with little regard to standards and regulations. The general rule of thumb to use is to be very careful of any single-width roller door insulated aluminium with an installed price of less than £900 inc. VAT.
Also, if there is a power supply failure, there is an internal manual override winding system that allows the door to be opened and closed manually. If you don’t have a side door into the garage, this can be expanded to work from outside the garage. Improvements in technology and pricing allow the use of a battery backup system to ensure multiple operations after mains power has failed, and this is a good system to consider.
