Technical Specifications, LPCB / LPS 1175

LPCB-Approved Roofing and Cladding Systems (LPS 1175)

Discover the CA Group selection of LPCB-approved cladding panels in compliance with LPS 1175.

Published in January 2019, LPS 1175 Issue 8 offers some substantial updates to the LPS 1175 security standard, and has been devised to improve the testing guidelines for security products. LPS 1175 Security Ratings are derived by the ability of the system to withstand sustained attack by experts, utilising a specific range of tools and accessories. This enables a far more realistic scope for security ratings, and considers both the delay (amount of time an intruder is able to attempt entry) and the risk (opportunist or planned).

The combination of factors determines the scope of the test conducted and provides a comprehensive approach to security ratings.
