When it comes to protecting your home, not all security standards are created equal.
PAS 24 is a minimum standard for enhanced security performance. It’s widely used in the UK for residential windows and doors, but it only simulates basic attack methods used by opportunistic intruders.
LPS 1175, on the other hand, goes much further.
PAS 24 tests resistance to limited force over a short duration.
LPS 1175 SR2 requires products to withstand sustained, deliberate attacks using a broader range of tools, like chisels, screwdrivers, and pliers, for up to 3 minutes.
LPS 1175 is recognised by the police (Secured by Design) and major insurers, offering far stronger real-world protection.
By choosing products tested to LPS 1175 SR2, you’re investing in a higher level of security, proven under intense, realistic conditions.
