Seceuroglide LT with Full Hood Woodgrain Finish (7 Colour Options) Insulated Roller door garage door Aluminium Seceuroglide

SeceuroGlide LT Insulated Electric Roller Garage Door (Woodgrain Foil)

The SeceuroGlide LT (Woodgrain Foil) is an electric, insulated aluminium roller garage door engineered to combine the architectural appearance of natural timber with genuine SWS UK manufacturing quality and certified safety compliance. It serves as a lighter specification alternative to the flagship SeceuroGlide Original, removing secondary acoustic webbing and specialist security attachments while retaining the same robust, double-skinned insulated aluminium curtain.

Many low-cost roller doors on the UK market compromise on basic safety, often relying on illegal single infra-red beams across the opening. The SeceuroGlide LT complies fully with UK safety regulations, using an active optical bottom edge safety sensor that stops and reverses immediately if an obstruction is met.

Supplied made to measure down to the exact millimetre up to 5200mm wide at no extra cost, this model rolls vertically overhead into an enclosed full hood box, preserving your clear drive-through clearance and driveway parking space.

The Advantage of Renolit Grained Foil Laminates

Standard painted roller doors use a flat liquid or powder coating that can show surface marks over time and requires periodic care. The SeceuroGlide LT Woodgrain model uses high-grade Renolit multi-layer exterior foil laminates bonded directly to the aluminium slats, delivering distinct practical benefits:

• Authentic Timber Grain Texture: The exterior foil features an embossed woodgrain texture that replicates real sawn timber, eliminating the flat plastic look of budget painted finishes.
• Seamless uPVC Window Matching: Specifically engineered to match Renolit-foiled uPVC window frames, fascias, and composite front doors across traditional oak, mahogany, and contemporary architectural greys.
• Superior Scratch and UV Resistance: The hard-wearing acrylic surface layer resists scratching, stone chips, and long-term sun bleaching, meaning no sanding, staining, or repainting is ever needed.
• Extended 10-Year Finish Warranty: Because foil laminate technology offers superior durability over standard paint coatings, SWS UK backs the woodgrain finish with an extended 10-year manufacturer warranty.

Full Hood Enclosure Included as Standard

This model comes complete with a powder-coated aluminium top box enclosure, providing practical and structural advantages:

• Mechanism Protection: Fully encloses the motor drive, axle barrel, and coiled slats, shielding them from dust, dirt, and accidental contact with ladders or stored items inside the garage.
• Ideal for Reveal Fitting: If installing between the opening brickwork rather than behind, the full hood boxes in the curtain roll completely from both the inside and outside, avoiding the need for separate on-site timber or plastic fascias.
• Draught Reduction: Enclosing the top coil helps minimise top-edge draughts and weather ingress, working alongside the dense guide brush pile and bottom rubber weather seal.

Certified Safety and Remote Automation as Standard

Unlike uncertified budget alternatives, the SeceuroGlide LT prioritises legal domestic safety, convenience, and reliable daily operation:

• Fully Compliant Optical Safety Edge: Fitted inside the bottom rubber seal, optical sensors detect any contact with an obstruction, stopping and reversing the curtain immediately.
• Two Remote Transmitters Included: Supplied with 2 x rolling-code handheld transmitters, using encrypted transmission frequencies to prevent code grabbing.
• Internal Emergency Manual Release: Direct winding eyelet and manual crank handle come standard on the motor side, ensuring you can open or close the door during a power failure.
• Anti-Drop Protection: Doors weighing over 26.5kg are fitted with an automatic wireless safety brake to prevent curtain drop in the event of mechanical motor failure. Lighter doors under 26.5kg are supplied with an adjustable LT dummy end axle shaft.

SeceuroSense Plus Wall-Mounted Control Unit

The standard automation package is powered by the intelligent SeceuroSense Plus receiver board, designed for straightforward installation and daily convenience:

• Built In LED Courtesy Light: Automatically illuminates your garage interior when the door opens, staying on for several minutes before turning off automatically.
• Front Cover Push Controls: Integrated open and close push buttons allow simple internal operation without hunting for a handheld keyfob.
• External Lighting Feed: Includes an integral relay connection supporting up to 300W of external garage or driveway lighting.
• Visual Fault Diagnosis: Clear external LED indicator lights provide instant operational feedback and simple fault diagnosis without removing the cover.
• Simplified Limit Setting: Limit positions can be set directly from the board using an integrated test lead for fast, accurate commissioning.
• No Floor Magnets Required: Built-in ground exclusion circuitry ensures clean floor contact without needing messy floor-mounted magnets.
• Optional Plug-In Alarm: Compatible with an optional acoustic alarm card housed neatly within the control enclosure to deter forced entry attempts.

Drive Upgrades & Smart Home Connectivity

For smart home automation and enhanced security feedback, the SeceuroGlide LT can be upgraded to the Somfy Rollixo Premium IO platform:

• Integrated 100dB Tamper Alarm: Housed directly inside the Rollixo panel, sounding immediately if the curtain is forced upward from outside.
• Two-Way Real-Time Feedback: Confirms whether your garage door is fully closed, open, or stopped directly on your smartphone screen or multi-channel remote handset.
• Somfy Smart App & TaHoma Hub Integration: Seamlessly pairs with Somfy TaHoma switch hubs for smartphone access, scheduled opening routines, and voice assistant control via Alexa or Google Assistant.
• Keygo Transmitters: Supplied with 2 x Somfy Keygo 4-channel IO keyfob transmitters as standard.

Practical Installation and Sizing Advice

• Inside Face Fit vs Reveal Fit: Internal face fixing behind the piers is recommended to maximise drive-through width and clearance height. For reveal-fixed installations, the full hood encloses the curtain roll completely, protecting the mechanism and creating a neat appearance from both sides.
• External Manual Release Requirement: If your garage has no secondary pedestrian side door or connecting house door, an optional external low-level keyed manual release must be ordered to allow entry during a power failure.
• LT Dummy End Adjustment: Because the LT does not use an internal counterbalance spring, SWS fits an LT dummy end on the non-motor side of the barrel. This features an adjustable internal shaft to set the axle to the exact bracket width. The shaft is intentionally stiff to pull on initial adjustment; once shifted, it moves freely into position before slotting into the endplate bracket.

* Always allow proper fitting tolerance when measuring your garage opening. A level floor across the opening gives the best bottom weather seal and the most reliable safety edge operation.

How to Order Your SeceuroGlide LT (Full Hood) Woodgrain – Options Guide

Every SeceuroGlide LT Woodgrain roller door is custom-manufactured down to the exact millimetre to suit your garage opening, supplied with an exterior Renolit woodgrain foil finish and a fully enclosed aluminium hood box as standard. When configuring your door online, work through the ordering steps below to select your sizes, woodgrain finishes, handing, fitting position, and automation upgrades.

1. Sizing: Selecting Your 'Up to' Pricing Bracket and Exact Dimensions

Our ordering menus use 'Up to' size brackets for online pricing, based on the Overall Door Width (including side guides) and the Guide Height (height from the floor to the underside of the full hood box, excluding the 300mm box itself above):

• Select Your 'Up to' Size: Choose the nearest 'up to' width and height bands from the drop-down menus that cover your overall dimensions. For example, if your required overall width is 2450mm and guide height is 2150mm, select 'Up to 2600mm' for width and 'Up to 2200mm' for height.
• Provide Your Exact Sizes: Enter your exact required overall width and guide height into the dimension boxes when proceeding to checkout. SWS will fabricate your door to these precise measurements at no extra cost (available up to 5200mm wide).

2. Door Curtain Woodgrain Foil Finish (Extended 10-Year Warranty)

Unlike standard painted finishes, these doors use high-grade Renolit exterior woodgrain foil laminates bonded directly to the aluminium slats. This durable, multi-layer coating provides superior resistance against UV fading, weathering, and surface scratches, carrying an extended 10-year manufacturer finish warranty compared to the 5-year term on standard paint finishes.

Choose from our 7 standard architectural woodgrain foil options to coordinate with your home:

• Golden Oak: Warm, classic mid-oak grain. The ideal match for traditional Golden Oak / Light Oak uPVC windows and composite entrance doors.
• Rosewood: Deep, rich reddish-brown timber tone suited to darker uPVC window profiles and red brick or stone properties.
• Mahogany: Distinctive dark reddish-brown hue designed for heritage properties and established dark timber joinery.
• Irish Oak: Subtle, lighter natural oak grain with a contemporary Scandinavian feel, matching modern Irish Oak window frames.
• Anthracite Woodgrain: Deep charcoal grey with an authentic embossed woodgrain texture, perfect for modern homes with textured RAL 7016 uPVC windows.
• Black Woodgrain: Bold, striking black with a tactile timber grain pattern, coordinating with contemporary black architectural cladding and entrance doors.
• White Woodgrain: Clean white finish featuring a subtle embossed grain, offering texture and depth over flat white paint.

3. Side Guide Channel Finish

The extruded aluminium guide rails are supplied in either White or Dark Brown as standard to complement your brickwork and foil selection. Alternatively, you can select the option to have the side guides factory powder-coated in a complementary colour to match your chosen woodgrain curtain.

4. Full Hood Cover Colour

Because this model comes complete with an aluminium top box enclosure to fully conceal the mechanism and protect the coiled slats, you can choose how it is finished:

• Standard Hood Finishes: Supplied in satin White or Dark Brown as standard to blend with traditional soffits, fascias, or brickwork.
• Colour-Coordinated Hood: Have your full hood box factory powder-coated to complement your chosen woodgrain finish (such as RAL 7016 Anthracite or RAL 9005 Black) for a uniform external appearance.

5. Electric Motor and Manual Override Handing

Choose which side you require the electric tubular barrel motor to be positioned on, selected as either Left-Hand Drive or Right-Hand Drive (viewed from inside the garage looking out).

The internal emergency manual release winding eyelet and crank handle are always situated on the same side as the motor unit, so ensure this side provides practical, unobstructed access inside your garage.

6. Door Installation Position & Hood Box Supports

Specify how the door will be fixed relative to your garage opening piers and lintel. On wider openings, intermediary hood support brackets are included to prevent lid deflection and ensure long-term stability of the enclosure:

• Inside Face Fit: Fitted to the internal brickwork face behind the opening. Keeps the guides and top box concealed behind the reveals to maximise clear drive-through width and height.
• Inbetween the Opening (Reveal Fit): Fitted between the structural opening piers and directly under the lintel. The full hood neatly encloses the roll from both inside and outside.
• Inside Face Fit with Centre Hood Support: For wider openings installed behind the piers, an intermediate upper support bracket is supplied to anchor the full hood box firmly to the lintel, eliminating cover flex.
• Inbetween Opening with Centre Hood Support: For wider reveal-fixed installations, an overhead intermediate bracket secures the box directly to the underside of the lintel for complete cover rigidity.

* As a rule of thumb, wider doors spanning over 3000mm benefit from intermediate hood supports to brace the box profile across the span.

7. Optional External Low-Level Manual Override System

Every door comes with an internal manual crank handle for power failures. However, if your garage has no separate pedestrian access door or connecting integral house door, you must order an external manual release system:

• This heavy-duty, lockable low-level keyed disconnect allows you to disengage the motor and wind the door open from the outside using a crank handle if the power fails.
• The external release is installed on the same side as your motor selection.
• Supplied as standard to pass through brickwork walls up to 500mm thick (the 7mm hex drive shaft can be extended on site if passing through deeper reveals).

8. Optional Alarm Kit for the SeceuroSense Plus Control Panel

For standard SeceuroSense Plus systems, you can add an optional plug-in acoustic alarm card. Housed directly inside the internal wall control panel, this sensor triggers an ear-piercing siren if forced lifting or tampering is detected at the bottom of the door when closed.

9. Upgrade to Somfy Electric Motor Drive & Somfy Rollixo Premium IO Control Panel

Upgrade your complete drive package to Somfy’s flagship IO-homecontrol platform:

• Built-In 100dB Tamper Alarm: Housed directly inside the Rollixo panel, sounding immediately if the curtain is forced upward.
• Real-Time Door Status Feedback: Two-way communication confirms whether the garage door is fully open, closed, or partially positioned directly on your smartphone app or multi-channel remote.
• Smart Home Ready: Seamlessly pairs with the Somfy TaHoma switch hub and Somfy smart apps for automated routines, voice assistant control, and remote access from anywhere.

Ordering and Sizing Guidelines

Pricing for the SeceuroGlide LT is based on overall door width including side guides and guide height (the height to the underside of the 300mm full hood box, excluding the box itself above):

• Example Calculation: For a clear daylight opening 2300mm wide x 2200mm high installed on the inside face of the brickwork piers, you need 75mm guides on each side (2300mm + 150mm = 2450mm over-guide width) and a 2200mm guide height. For pricing, select the Up to 2600mm width bracket and the Up to 2200mm height bracket.
• Headroom Requirement: Allow 300mm of clear headroom above the guide channels to accommodate the 300mm x 300mm full hood enclosure.
• Drive Handing: Motor drive side (left or right, viewed from inside looking out) must be specified when ordering. The manual override eyelet and crank handle exit on the same side as the motor.
• Between-Fix Advantages: Because this door includes a full hood box as standard, it is completely self-contained and suitable for fitting between the opening without needing on-site timber or PVC fascias to cover the back of the roll.

SeceuroGlide LT (Full Hood) Installation Guidance

Fitting a SeceuroGlide LT roller garage door with a full hood enclosure is straightforward for a tradesperson or competent DIYer. Because this model includes a self-contained 300mm x 300mm aluminium box, assembling the frame square and securing the top enclosure firmly ensures a smooth, quiet roll and trouble-free safety edge operation.

1. Pre-Installation Checks and Tolerances

Before unpacking the door components, verify the opening structure and dimensions:

• Floor Levelness: Check the garage threshold with a long spirit level. The floor must be reasonably level across the opening width. An uneven threshold prevents the bottom rubber seal and optical safety edge from seating squarely, which can trigger nuisance safety reversals when closing.
• Structural Soundness: Ensure the brickwork piers and lintel are flat, plumb, and free of obstructions (such as conduit, alarm sensors, or gas meters). The fixing face must support the weight of the assembly and the operating motor torque.
• Headroom and Pier Clearances: Confirm you have a minimum of 300mm clear headroom above the guide height for the full hood enclosure, along with at least 75mm (or 90mm for doors over 3000mm wide) on each internal pier to mount the guide channels.

2. Assembling the Frame and Securing the Hood Enclosure

Building the structural frame square is the most critical stage of the installation:

• Attach Guides to Hood Endplates: Lay the extruded guide channels flat on clean cardboard or dust sheets. Slot the legs of the cast aluminium endplates (already mounted to the backbox panel) directly into the tops of the side guides.
• Check Diagonals for Squareness: Lift the assembled guide and hood frame into position against the garage opening. Use a tape measure to check diagonally from the top corner of one endplate to the opposite bottom corner of the guide. Both diagonal measurements must match exactly.
• Fixing into Masonry: Plumb both guides vertically with a spirit level and clamp them into place. Drill and plug through the pre-drilled fixing holes into solid masonry using suitable heavy-duty fixings.
• Intermediate Hood Supports (Wider Doors): If intermediate hood support brackets are supplied for wider spans, secure them firmly into the lintel overhead to brace the box profile and prevent cover flex.

3. Mounting the Axle Barrel and Adjusting the LT Dummy End

The axle assembly carries the motor at one end and the anti-drop assembly or dummy shaft at the other:

• Lift Axle into the Hood: Secure the motor head into its dedicated mounting bracket on your chosen drive side endplate, ensuring the manual override eyelet faces forward or downward for easy hook engagement through the hood fascia.
• Adjust the LT Dummy Shaft: Unlike standard spring-assisted doors, the LT relies on a direct-drive dummy end on the non-motor side. The internal shaft allows width adjustment to seat the axle accurately between the endplates. This shaft is intentionally stiff to pull on initial adjustment; once shifted, it moves freely into position and drops into the support bracket bearing.
• Safety Brake Alignment (Doors over 26.5kg): If your door is supplied with a wireless safety brake, ensure it is seated level and locked correctly onto the dummy endplate bearing before hanging the curtain.

4. Hanging the Insulated Curtain and Setting Autolocks

Take care when unwrapping the curtain to avoid scratching the powder-coated or woodgrain finish on the floor:

• Feeding into Guides: With the axle secured and motor limits roughly positioned, carefully feed the top edge of the curtain over the barrel and guide the side edges down into the brush-lined channels.
• Attaching Locking Straps: Connect the heavy-duty auto-locking straps evenly spaced across the top slat into the axle collar slots.
• Setting the Down-Locking Position: When the door is fully closed, the locking straps should form a slight downward 'knuckle' angle against the barrel. This mechanical angle clamps the curtain firmly down, preventing anyone from levering the door open from outside.
• Fitting the Front Hood Cover: Once the curtain is running smoothly and limits are set, hook the front curved aluminium cover into position on the endplates and secure it with the provided rivets or self-tapping screws.

5. Commissioning the Motor, Safety Edge, and Controls

Once mechanically hung, wire the control panel and complete the final safety setup:

• Mounting the Control Unit: Fix the SeceuroSense or Somfy Rollixo receiver panel to an internal wall at approximately chest height, within reach of a standard 13-amp domestic power socket.
• Setting Limit Stops: Set the mechanical or digital motor limits so the curtain stops neatly at the top (leaving the bottom slat resting just below the top of the guides inside the hood) and seals firmly against the floor at the bottom without over-compressing the locking straps.
• Optical Safety Edge Testing: Pair the wireless transmitter in the bottom rubber seal with the receiver board. Test the safety system by placing a 50mm timber block on the floor beneath the door path. On making contact, the door must immediately stop and reverse upward.
• Emergency Override Test: Disconnect the mains power and test the manual crank handle to confirm the door can be wound open smoothly by hand in the event of a power failure.

* If you fitted an optional external low-level manual release, test key operation from the outside to confirm the hex bar turns the motor gearbox freely before leaving the site.

Details on the SeceuroDrive Motor Limit Setting Instructions can be watched here.

Please Note: Important Information when installing the Seceuroglide LT Roller Doors.

In the absence of the spring we apply an LT dummy end. This has an adjustable shaft in it. This is designed to be moved so the axle becomes the right size. This is stiff to pull but once its moved it moves freely. This then slots in to the bracket as normal.

For  doors which have been supplied with a dummy end, the bearing will no longer be welded to the end.   Instead, the bearing will now be located within the accessory box and will need to be installed manually.

To install the bearing, simply slide the bearing ontl the end of the dummy end shaft.

Straightforward Maintenance Requirements

To keep your SeceuroGlide warranty fully valid, your door simply requires basic, sensible care:

• Keep Guide Channels Clear: Periodically wipe out the aluminium side guides and brush pile strips with a damp cloth to clear away grit, salt deposits, and debris. Do not apply heavy grease or oil to the brush strips.
• Wash the Curtain and Hood Finish: Clean the outside face of the aluminium slats and full hood cover every few months with warm soapy water (car shampoo works well) and a soft cloth, especially in coastal areas where airborne salt can accumulate.
• Maintain Threshold Clearance: Ensure the floor beneath the door remains free of stones, ice build-up, and leaf litter so the optical safety edge and rubber seal seat flat and true on every closure cycle.

* Always register your door serial number with SWS UK following installation to activate your extended manufacturer warranty records.

How to Measure for Your SeceuroGlide LT Roller Door

When ordering a SeceuroGlide LT roller garage door with a full hood, getting your measurements right from the start avoids delays and guarantees a clean fit. Use this guide alongside our 3D dimension drawing to identify exactly what to measure and how to specify your ordering sizes.

* SWS manufacture your door to the exact millimetre sizes you enter at checkout. The online ordering sizes always refer to the Overall Width (including side guide channels) and the Guide Height (floor to underside of the 300mm full hood box), not the opening hole size.

Understanding the Key Ordering Dimensions

Option A: Installing Behind the Opening (Inside Face Fit – Recommended)

Fitting behind the brickwork piers gives you the greatest drive-through width and clearance height:

• Measure the Daylight Width: Measure the clear distance between the internal faces of your brick piers at top, middle, and bottom. Use the narrowest measurement.
• Calculate Over-Guide Width: Add the two guide widths to your daylight opening width. For doors up to 3000mm wide using 75mm guides, add 150mm (e.g., 2300mm opening + 150mm = 2450mm Ordering Width). Ensure you have at least 75mm of flat pier face on each side inside the garage.
• Measure Daylight Height (Guide Height): Measure from the finished floor to the underside of your lintel at both sides. If the floor is level, this measurement is your Guide Ordering Height.
• Check Your Headroom: Confirm you have a minimum of 300mm of unobstructed headroom above the underside of the lintel inside the garage to accommodate the 300mm x 300mm full hood enclosure.

Option B: Installing Inbetween the Opening (Reveal Fit)

Used when internal headroom or side pier space is limited, fixing directly between the reveals. The full hood neatly finishes the door from both inside and outside:

• Measure the Width Between Reveals: Measure between the brickwork opening at three heights (top, middle, bottom). Take the smallest figure and subtract a 10mm fitting tolerance (5mm per side) to arrive at your Over-Guide Ordering Width. This ensures the frame fits cleanly between rough or out-of-plumb brickwork.
• Calculate Guide Ordering Height: Measure from the finished floor to the underside of the lintel. Deduct 300mm (the height of the full hood box) to calculate your Guide Ordering Height. The remaining space below the box becomes your clear drive-through height.

Essential Measuring Tips Before Finalising Your Order

• Check the Floor Level: Place a long spirit level across the threshold. The optical safety edge and bottom weather seal need a reasonably level floor across the entire opening to bed down correctly without triggering false safety reversals.
• Inspect the Lintel and Ceiling Depth: Check back into the garage for at least 350mm behind the lintel to ensure no ceiling joists, light fittings, gas pipes, or roof trusses clash with the 300mm x 300mm full hood enclosure.
• Double-Check Sideroom Obstructions: Confirm the internal pier surfaces are clear of consumer units, surface-mounted conduit, or shelving where the guide channels and fixing angles will mount.

* If your opening is out of square or you are unsure which dimensions apply to your 3D drawing, contact our team with your measurements before ordering and we will gladly verify your ordering sizes.
