SeceuroDoor 100 Insulated Steel Roller Door
Hardened Steel Insulated Door
The SeceuroDoor 100 sits at the top of the SeceuroDoor insulated roller shutter range, designed specifically for larger openings and more exposed locations where both wind performance and insulation are critical. It features a 100 mm deep, double-skinned hardened steel slat with a 23 mm thick lath construction, providing a much more substantial curtain than standard insulated shutters.
The twinwall steel makes this profile especially resistant to damage and reduces deflection on wide or tall doorways up to 7000 mm x 7000 mm. This is a great roller door for large openings in exposed locations or where higher levels of insulation are required.
Why insulated roller doors matter
In many modern industrial and commercial buildings, external doors are part of the thermal envelope and have a direct impact on energy use, working conditions, and product quality. Insulated roller doors help reduce heat loss from heated warehouses, production areas, and distribution hubs while limiting cold draughts and condensation around loading bays. Compared with basic single skin shutters, double-skinned insulated curtains greatly improve temperature stability and cut down on noise transfer.
Unlike sectional doors, insulated roller shutters achieve high levels of thermal and acoustic performance without needing deep horizontal tracks running back into the building. The SeceuroDoor 100 combines these insulation benefits with the compact footprint and straightforward fixing of a roller shutter.
Why choose SeceuroDoor 100?
The SeceuroDoor 100 is intended for larger, more demanding openings. Its highly rigid curtain holds its shape and remains stable across spans up to 49 m². This extra stiffness, combined with appropriate guides and fixings, delivers a wind class rating of up to Class 5, making it particularly suitable for coastal sites, exposed yards, and tall openings.
For buildings that must stay warm and operational in poor weather, this higher wind performance means less curtain movement, less rattling, and a reduced risk of wind driven damage over time. The SeceuroDoor 100 serves as a direct alternative to large sectional or sliding doors, offering high insulation, strength, and weather resistance with a neat, compact roll.
Thermal and Acoustic Insulation

Minimal thermal bridges and the use of CFC-free insulation infill ensure good thermal insulation, helping to keep internal temperatures more stable and reduce heating demand. The curtain and sealing technology used around the entire shutter reduce noise from both inside and outside.

SeceuroDoor Installation Options
We are able to offer four standard variations of guide angle arrangement. The appropriate solution depends on whether the door is being fitted internally or within the opening, and on the available fixing points available within the aperture.

Guide angle inset or outset |
Universal,-Laser-cut,-Folded-End-Plate |
| Flag outset | Outset |  |
| Flag Inset | Inset | |
| Reveal | Outset | |
| Mixed | Inset/Outset |
All arrangements use universal, laser-cut, folded endplates for strength and accurate alignment. Guide angles can be inset or outset relative to the opening, allowing the door to be installed neatly and securely to steelwork or masonry.

Typical applications
- Large industrial warehouses and logistics hubs in exposed or coastal locations.
- High bay production buildings and distribution centres where wind loading on large doors is a concern.
- Agricultural, biomass and recycling plants with tall and wide openings that must remain secure and weather-tight.
- Refurbishment projects replacing older sectional, sliding or basic roller shutters where higher insulation and wind performance are required.
Where the SeceuroDoor 95 will meet the needs of most large insulated openings, the SeceuroDoor 100 offers an extra margin of strength and wind resistance for the most demanding sites, while still providing the compact footprint and day to day practicality of a high quality industrial roller shutter door.
Frequently Asked Questions
When should I choose SeceuroDoor 100 instead of SeceuroDoor 95?
Choose the SeceuroDoor 100 when the opening is particularly large or exposed and you need the highest wind performance and curtain rigidity in the range. It is the better option for coastal sites, tall doors, and situations where engineers are concerned about wind load, deflection, and long-term stability. The SeceuroDoor 95 is still a great option in the same size ranges for less extreme environments.
How wind-resistant is the SeceuroDoor 100 and where is it suitable?
The SeceuroDoor 100 can achieve a wind class rating of up to Class 5 (depending on size, guide configuration, and specification), which is significantly higher than many standard roller doors. This makes it ideal for exposed industrial yards, coastal locations, high-bay warehouses, and large openings where strong winds are a regular issue.
What insulation performance can I expect from SeceuroDoor 100?
The double-skinned steel curtain with foam infill and minimal thermal bridges provides excellent thermal insulation and improved acoustic performance compared to single-skin shutters. In practice, this helps reduce heat loss, cut draughts, and lower noise transmission around large external openings.
Can the SeceuroDoor 100 replace a sectional or sliding door?
Yes, in many cases the SeceuroDoor 100 can be used as an alternative to large insulated sectional or sliding doors, especially where you prefer a compact vertical roll rather than horizontal tracks or sliding gear. It offers comparable insulation and strength, with a simpler overhead footprint and fewer moving parts.
What maintenance is required for a SeceuroDoor 100 insulated roller door?
Like any industrial roller door, the SeceuroDoor 100 should be inspected and serviced regularly in line with its usage and standard health and safety requirements. Routine maintenance typically includes checking fixings and guides, inspecting the curtain and seals, verifying the correct operation of motors and safety devices, and lubricating moving components where specified in the maintenance instructions.
