Enhances security windows & doors:
The Secured by Design (SBD) scheme was introduced in 1989 by the Association of Chief Police Officers to help them stem the rising tide of burglaries.   The SBD document requires that all windows and door assemblies are covered by Kitemark or equivalent certification to BS 7950 for domestic windows and PAS 24 for residential doors.

Windows are tested by replicating the forces that would be applied by an adult male intruder using implements such as a screwdriver and crowbar.   All hardware and potential access points on the window are tested in an attempt to create a hole through which an average adult male could enter.   The test for enhanced security is purely against intruder attack rather than a test of an individual hardware component.

  • Manipulation of hardware
  • Assessment of glazing security
  • Mechanical loading test
  • Manual check test
