Security you can trust
Unlike ordinary doors, Rockdoor isn’t made from timber. It’s a fully engineered composite system, reinforced with aluminium and uPVC profiles combined with high-density Polyurethane foam (PU) foam to stand up to forced entry.
Rockdoors are 60% stronger than standard composite doors — robust, reliable, and built to keep your home and family safe and secure.
With a Rockdoor, you can just lock and leave your home, placing your trust in our security.
Key features
- Aluminium Reinforced Frame: Prevents warping and adds unrivalled 360° strength.
- Multi-point Locking System: Engages multiple bolts into the frame with a turn of the key or thumb turn.
- S-Glaze Technology: Glass is locked into the door itself, not beaded out, eliminating a common break-in point.
- Anti-Snap, Anti-Bump Cylinders: Protects against common lock-picking and snapping techniques.
A Rockdoor doesn’t just protect your home — it adds value, efficiency, and peace of mind.
Engineered for strength
Every Rockdoor features a continuous aluminium box section around the entire door sash. These box sections, with a 10 mm-thick leading edge, are mitred at each corner to form a full loop of reinforcement, preventing bowing, bending, or deflection over time. This allows us to offer a No Bow Guarantee on all doors.
Aluminium resists moisture and won’t warp like timber, providing a solid foundation. Hinges, glazing units, and locking straps are all fixed directly into the aluminium frame, enhancing durability and overall security.
The German-engineered multi-point locking system is fully integrated into the frame. Steel hooks engage multiple points along the door, with full-length keeps providing stronger engagement than standard pocket-style keeps. This design distributes locking points evenly, offering superior resistance against forced entry.
Police approved design
Every Rockdoor is available with Secured by Design (SBD) accreditation — the official UK Police initiative that recognises the very best in home security.
That means our doors are tested, proven, and trusted to stand up to real-world break-in attempts. From drilling and crowbar attacks to forced entry, Rockdoors are built to keep intruders out and give you complete peace of mind.
We’re proud to have been the first in the industry to achieve Secured by Design accreditation for French and double doors, setting the benchmark for the entire composite door market.
Deluxe hinges
Rockdoor hinges are fixed directly into the aluminium frame, carrying the door’s weight rather than relying solely on screws. Teflon bushes reduce friction for smooth operation over time. This design improves durability and ensures the hinge side of the door is as secure as the lock side.
S-Glaze technology
Rockdoor’s exclusive S-Glaze integrates the glass unit between the door’s skins, making it part of the structure rather than a separate add-on. This eliminates weak points where panels can be removed and improves thermal performance by removing draught paths common with the cassette.
Keys & cylinders
Rockdoors feature AP V3 TS007 3-star cylinders, meeting the highest security rating for euro-profile cylinders. The cylinder is independently tested to the latest security requirements of PAS 24. Each Rockdoor comes with five Snake-rail dimple keys as standard, featuring a 30% larger grip for easier handling.
For extra protection, optional galvanised steel rods are embedded inside the foam core. This gives the inner core an extra level of security, in a similar way to reinforced concrete.
Rockdoor offers optional features such as key-wind locks, switch-latches or thumb-turns on the inside to accommodate different user needs.
Made to measure
Manufactured at our Lancashire plant, every Rockdoor is made to measure — never cut to fit, which can weaken the door and compromise the unique security and strength that define Rockdoor.
