Secured by Design Options

Multi-point locking as standard on all opening sashes. Internally beaded—glass cannot be removed from outside. Upgrade to Secured by Design certification for insurance-preferred installations.

Multi-Point Locking

Shoot-bolt locking engages at multiple points around the frame. Far more secure than traditional single-point locks.

Internal Beading

Glass units are secured from inside the property. Cannot be removed from the exterior, preventing break-in attempts.

Secured by Design

Police-backed security standard available on request. Recognised by insurance companies for reduced premiums.

Key-Locking Handles

Optional key-locking handles for enhanced security. Child safety restrictors available for upper floor windows.
