Secured by Design (SBD) specifications for UK composite doors require the entire door set (frame, leaf, hardware) to pass PAS 24:2016 testing, which simulates sustained physical attacks. Often called "Police Preferred Specification," these doors must feature 3-star TS007 cylinders, laminated glass, and multi-point locks to reduce burglary risk by 75%.
Key SBD Specification Requirements for Composite Doors
- PAS 24 Accreditation: The minimum standard, requiring doors to withstand rigorous, manual, tool-based attacks.
- 3-Star Cylinder: Cylinders must meet TS007:2014+A2:2018 (3-star) or Sold Secure Diamond standard, protecting against snapping and picking.
- Laminated Glass: Mandatory laminated safety glass (typically 6.8mm) ensures it stays intact if attacked, unlike standard toughened glass.
- Multi-Point Locking: A minimum of a three-point locking system is required.
- Reinforced Frame & Hinges: Hinge-side security must include dog bolts or anti-lift pins, and frames must be strengthened.
- Quality Control: Manufacturers must undergo annual audits to ensure consistent production standards.
Usage Examples
Usage: Commonly required for new-build housing, social housing, and high-security residential upgrades.
