Premier Security Ballistic & Blast Ltd
Security windows play a critical role in protecting buildings, occupants and assets within today’s built environment. As threat levels rise and regulations become more demanding, architects, contractors and security consultants require window systems that deliver certified protection without compromising natural light, design intent or day-to-day functionality.
Premier’s range of LPS 1175 security windows, blast resistant windows and specialist glazing systems are engineered to resist real-world threats including forced entry, blast pressure and impact. Tested to recognised UK standards, our security windows provide proven performance while remaining fully bespoke to suit commercial, retail, government and high-risk environments. By working with Premier, you gain confidence that your window systems meet compliance requirements, aesthetic expectations and long-term security objectives, all delivered by a trusted UK manufacturer.
LPS 1175 security windows are independently tested window systems designed to resist forced entry using real attack methods. Unlike standard windows, LPS 1175 security windows are assessed as a complete system including frame, glazing, fixings and locking hardware, providing proven protection against intrusion.
LPS 1175 is a UK Loss Prevention Standard developed by LPCB and BRE. For security windows, it measures how long the window can resist physical attack using specific tools. The higher the rating, the longer the window delays an intruder, giving valuable time for alarms or response.
LPS 1175 security windows are available in several Security Ratings:
SR1 offers protection against opportunistic attacks using basic hand tools
SR2 protects against more determined intruders using mechanical tools
SR3 provides enhanced resistance against heavier tools and longer attack times
Higher SR levels may be specified for critical or high-risk environments.
Yes. LPS 1175 security windows can be fully glazed while still achieving certified ratings. During testing, both the glazing and the framing system are attacked together, ensuring the entire window assembly performs as one secure unit rather than relying on glass alone.
LPS 1175 security windows are tested by LPCB or BRE approved laboratories. The windows are locked and attacked using defined tools for set durations. Frames, glazing, fixings and hardware must all remain secure for the rating to be achieved, ensuring real-world performance.
Yes. LPS 1175 security windows are increasingly used in high-value residential homes where enhanced protection is required. They are ideal for homeowners seeking higher security without changing the external appearance of the property.
LPS 1175 security windows can be integrated with blast resistant or ballistic glazing where required. This allows a single window system to deliver forced entry resistance alongside protection from explosion or ballistic threats, depending on the project specification.
The correct rating depends on the threat level, building type, location and asset value. Our team can assess your requirements and recommend the appropriate LPS 1175 security window specification to ensure proportionate and compliant protection.
