Windows by Design : Casement Window Cross-Section

1. Internal beads (to BS7950 security standard) ensure glass cannot be removed from the outside
2. Weatherproof Gasket
3. Reinforcement to manufacturing guidelines
4. Multichamber profile for strength and rigidity
5. Outer frame
6. Victorian shaped profile to all
7. Clearline gasket as standard (gasket below sightline of frame)
8. K Glass to 28 mm sealed unit to conform with Document "L"

All frames available in white, rosewood or oak finishes.

All have shoot bolt locking mechanisms for high security and high security friction hinges.

All windows have external cills and concealed drainage unless otherwise specified. If there are no cills, then face drainage is required.

Additionally, forming a clear line of escape in the event of a fire or other hazard, the wide 90 degree opening hinge is the practical answer to safety concerns. The hinge opens the window to its full extent, allowing a clear and speedy exit from any room.

It is recommended that there is at least one of these somewhere in any dwelling.

Finally, front door closure advanced security features include 2 Point Top Hook Lock, Top Roller Cam, Deadlock and Lockable Centre Latch, Bottom Roller Cam and 2 Point Bottom Hook Bolt - plus 2 point Dog Bolt Hinge Side Locking giving a total of 10 Locking Points.

Standards & Testing

The standards listed here are those currently identified by the Association of Chief Police Officers, Crime Prevention Initiative for Secured by Design "Police Preferred Specification" licenses.

Secured by Design is the UK Police flagship initiative supporting the principles of 'designing out crime' by use of effective crime prevention and security standards for a range of applications.

Secured by Design supports one of the Government’s key planning objectives - the creation of secure, quality places where people wish to live and work.

Windows and doors offered by betterdiy.com
are approved under the Secured by Design scheme
and carry the Secured by Design logo

In addition, some security products that do not have the benefit of a suitable public test standard may have been subjected to and passed a rigorous evaluation by a technical authority acceptable to ACPO CPI. (e.g. HOSDB - Home Office Scientific Development Branch and Thatcham – Motor Insurance Repair Research Centre)

Current Standards:

DOORS & LOCKS
BS 3621:2004 Thief resistant locks. Key egress. The minimum standard for locks on external or entrance doors to be acceptable to the Association of British Insurers (ABI) and the police service. The effectiveness of the lock also depends on the quality of the door, frame and other hardware which is not tested by this standard and which may fail before the lock.
BS 8621:2004 Thief resistant locks. Keyless egress. As above but accommodating locks that offer egress without the use of a key.
BS:EN 1303:2005 Building Hardware Cylinder for locks requirements & specified test methods. The minimum standard for the cylinder on locks for multi-point locking on external or entrance doors. The effectiveness of the lock depends on the quality of the door, frame and other hardware which is not tested by this standard and which may fail before the lock cylinder.
LPS 1242: Issue 1, 2003 Requirements for testing procedures for the approval and listing of cylinders for locks. Based on EN 1303 this standard incorporates additional requirements to address critical issues relating to the security provided by cylinders and associated keys.
BS: PAS 23-1: 1999 General performance requirements for door assemblies. Part 1, single leaf, external door assemblies (including all material relevant annexes). A performance standard for door sets, which certifies that a particular door set, is fit for purpose. The security rating is not sufficient for police/insurance purposes and products must also have PAS24.
BS: PAS 24-1: 1999 Enhanced security performance requirements for door assemblies. Part 1 single leaf, external door assemblies. An attack test standard for door sets which certifies that a particular door, frame, lock and hardware set has withstood a series of physical tests based on common methods of burglary. This is the minimum police requirement for Secured by Design dwellings.
LPS 1175: Issue 5.1, 2004: Specification for testing and classifying the burglary resistance of building components, strong-points and security enclosures. This includes doors, shutters and grilles for commercial premises and higher risk domestic premises and is acceptable to the ABI and the Police. The standard has 6 levels, 6 being the highest and levels 1 and 2 equivalent in many respects to BS:PAS24 in relation to doors.
LPS 1268 (Draft) Specification for testing and classification of hotel doorsets. This test takes elements from both BS: PAS 24 and LPS 1175. Doorsets are subjected to a number of additional tests, e.g. Fire/smoke resistance, Acoustic performance, etc.
LPS 1270 (Draft) Specification for testing and classifying the burglary resistance of security glazing and glazing films. Based on LPS 1175 this standard enables specifiers to select glazing films that offer resistance to manual attack equivalent to the building products in which the glass or film is to be used.
