The GDO ROLL77 Somfy Edition combines premium French-engineered Somfy automation with precision UK manufacturing for the ideal balance of durability, convenience and everyday value.

Complete Somfy Remote & Wireless Control Package

Operating your garage door is effortless from both inside your vehicle and within the home. Each GDO ROLL77 Somfy door is supplied with a complete control package as standard:

Strong, Insulated 77mm Aluminium Slats

The door curtain is constructed from 77mm deep, double-skinned aluminium slats with a dense CFC-free insulating foam core. This creates a rigid barrier against forced entry while providing excellent thermal and acoustic insulation—reducing draughts and keeping the garage warmer, drier and more usable as a workshop, gym or utility room.

Made to Measure in 5 Signature Finished Colours

Every GDO ROLL77 is manufactured in the UK to your exact opening dimensions (up to 5200mm wide and 2900mm high) at no extra charge. Choose from five durable, low-maintenance finished curtain colours to suit your home:

Matching Guides & Hoods: Heavy-duty aluminium side guides (75mm or 90mm wide depending on door size) and optional half or full hood covers are supplied in the matching finished colour as standard for a seamless, coordinated look around the entire opening. Custom contrasting colour combinations are available on request.

Reliable Power Failure Manual Override

In the event of a power cut, the GDO ROLL77 includes an internal emergency manual override system as standard. The supplied winding handle attaches directly to the Somfy motor eye, allowing you to open or close the door smoothly by hand from inside the garage. For garages without a separate pedestrian side door, an optional low-level external manual release lock is available so you can access the override from outside.

Multi Door Installations & Additional Somfy RTS Controls

Because this model uses the proven Somfy RTS radio platform, you can easily integrate additional accessories.

Construction, Drive & Insulation

The GDO ROLL77 Somfy Edition is constructed from high quality 77mm deep, double-skinned aluminium slats with a dense CFC-free foam-filled core. Every door is made to measure as standard, manufactured to your exact millimetre measurements in both width and height for an airtight, precision fit.

Powered by a genuine Somfy tubular electric motor backed by a 5-year warranty, this model delivers ultra-smooth, whisper-quiet operation and outstanding long-term reliability. The drive mechanism includes an internal emergency manual override as standard, operated via a supplied winding handle that hooks into the motor eye. You can specify left or right-hand motor handing when ordering to best suit your power supply.

Included Somfy RTS Automation & Optical Safety Edge

This door is supplied as a complete, ready-to-install automated package:

Barrel, Endplates and Headroom

The insulated curtain rolls neatly around an engineered steel barrel supported on both sides by 300mm x 300mm steel endplates. This 300mm measurement is the headroom required if you wish to fully conceal the roll inside the garage behind a lintel or hood cover. Always allow for approximately 50mm to 110mm of curtain hang-down into the guides when the door is fully raised if clear drive-through height is critical.

Guides, Sizes and Clear Openings

Ordering size: Over Guide Width (OGW) x Guide Height (GH).

Doors over 3000mm wide (supplied with 90mm wide guides):
• Clear opening width = Ordering width (OGW) less 180mm (90mm each side)

Installing a GDO ROLL 77 insulated electric roller garage door is a straightforward process for a competent DIY enthusiast or tradesperson. Because every door is made to measure, it will arrive ready to fit your exact required dimensions.

Safety Note: A minimum of two people are required to safely lift the door curtain and motor assembly into place.

The GDO ROLL 77 is highly versatile and can be installed in three main ways depending on your garage structure:

• Internal Face Fit (Recommended): Fitting behind the brickwork piers. This is the most common installation method, keeping the guides, curtain roll, and motor fully concealed inside the garage while maximizing the drive-through width and height.
• Inbetween Fit (Reveal Fit): Fitting directly between the brickwork under the lintel. The guides and endplates will be visible from the outside, so choosing a half or full hood cover is recommended to tidy the exposed roll and protect it from the elements.
• External Face Fit: Fitting on the outside face of the garage. Ideal if you lack internal headroom. Note: A full hood cover must be ordered for external fitting to protect the curtain, guides, and motor from weather. The motor handing and curtain orientation will also be reversed.

The installation process generally follows these main stages (please refer to the full PDF instruction manual provided with your door for complete details):

1. Pre-Installation Check: Ensure all components are present, including the guides, barrel assembly, curtain, Somfy control panel, and accessories. Verify the opening is square and clear of obstructions.
2. Prepare the Guides: Pre-drill the 75mm or 90mm aluminium guide rails for fixing.
3. Fix the Guides and Endplates: Secure the guide rails and the 300mm steel endplates (or complete box assembly if a full hood is ordered) to the masonry or timber frame. Ensure everything is perfectly level and plumb.
4. Install the Axle and Motor: Secure the steel barrel and Somfy motor assembly between the endplates.
5. Fit the Emergency Override: Install the manual winding eyelet so it is accessible in the event of a power failure.
6. Insert the Curtain: Carefully guide the insulated aluminium curtain into the guide rails and attach the top locking straps to the barrel.
7. Wire the Control Panel: Mount the Somfy wall control panel internally (ensure a suitable 13-amp socket is nearby) and connect the motor and optical safety edge system.
8. Set Motor Limits: Use the supplied limits tool or control board to set the exact open and close stopping points for the door.

The Somfy wall-mounted control panel contains the radio receiver for the remote controls and wireless wall switch. Please note: The control box and its components are not waterproof and must always be installed internally or in a suitably rated waterproof casing if fitting the door externally.
