2.4m High AcoustiGuard® SR1 (A1) LPS 1175 Acoustic Fencing Kit

2.4m High AcoustiGuard® SR1 (A1) LPS 1175 Acoustic Fencing Kit

The 2.4m High AcoustiGuard® SR1 (A1) LPS 1175 Acoustic Fencing Kit is an elite perimeter solution designed for high-security environments where noise control is a critical operational requirement. With its substantial 2.4-metre height, this system provides an imposing physical deterrent and a highly effective acoustic screen, making it the ideal choice for safeguarding critical infrastructure, industrial facilities, distribution hubs, and protecting residential communities from significant noise sources. It uniquely combines LPCB-certified intrusion resistance with proven acoustic performance compliant with European standards. Each kit is built with premium, long-lasting materials, including UC4-treated timber and galvanised steel, to ensure maximum durability. To aid in project efficiency, the panels are supplied fully assembled, ready for lifting and installation by professional teams.

Understanding LPS 1175 SR1 (A1)

Independent, third-party certification is the ultimate measure of a security product's reliability. The AcoustiGuard® system has earned the LPS 1175 SR1 (A1) certification from the Loss Prevention Certification Board (LPCB), a world-leading authority on security testing. LPS 1175 is the definitive standard for assessing the resistance of security products to determined attempts at forced entry. The SR1 (A1) rating certifies that this fencing system can withstand a continuous attack for a minimum of 60 seconds from an assailant using a range of small, concealable hand tools, such as screwdrivers, pliers, and knives, which are typically used in opportunistic attacks. The test rigorously simulates a real-world scenario to ensure the product's effectiveness. By achieving this standard, the AcoustiGuard® fence guarantees a crucial delay factor, impeding intruders and allowing vital time for a security response. Its resilience is significantly bolstered by a 358 security mesh panel that is integrated deep within the panel's core, forming a barrier that is exceptionally tough to breach. This certified protection offers tangible assurance that your perimeter is defended by a system tested to the highest industry benchmarks.

Understanding BS EN 1793 and BS EN 1794 Compliance

Beyond its formidable security features, the AcoustiGuard® system excels as an acoustic barrier, fully compliant with stringent European standards. It is also designed in accordance with the specification for Highways Works Clause 2504 and uses timber treated under Sector Scheme 4, confirming its suitability for deployment on the UK's most critical infrastructure projects. The system is tested and complies with BS EN 1793 Road Traffic Noise Reducing Devices, BS EN 1794-1 and BS EN 1794-2. This is the benchmark standard for measuring a barrier's effectiveness in controlling unwanted noise, assessing its ability to both insulate from and absorb sound. The system’s remarkable sound insulation capability stems from its high-mass design, featuring an average panel density of 71kg/m² (excluding posts). The intricate, layered construction, combining dense timber boards, a specialised EchoAbsorb insulation core, and the integrated security mesh, creates a formidable barrier to airborne sound. The standards also confirm that the barrier is structurally robust, safe for public areas, and environmentally durable by testing for mechanical strength, wind pressures, and potential impacts. The system's integrity is ensured by the use of heavy-gauge steel posts embedded in solid concrete foundations. This complete standards compliance affirms the AcoustiGuard® system's status as a top-tier, dependable solution for comprehensive perimeter control.

Features and Benefits

The 2.4m AcoustiGuard® SR1 fencing kit is loaded with features designed for superior performance, durability, and adaptability.

• Unmatched Dual Certification: Offers a single, elegant solution that is both LPCB-certified for SR1 (A1) security and compliant with BS EN 1793 for acoustic performance. This integrated design is more efficient and cost-effective than installing separate systems.
• Premium, Long-Life Materials: The timber components are all Class UC4 Tanalised, a superior pressure treatment that conforms to BS 8417 and allows for permanent ground contact without risk of rot or insect damage. The steel components are protected from the elements by galvanisation to ISO 1461 or zinc plating to ISO 4042/ISO 2081.
• State-of-the-Art Panel Engineering: The 2.42m wide panels are built using an advanced multi-layer method. They consist of dense 150x22mm EchoAbsorb Straight Boards, a central layer of 475x75mm EchoAbsorb Insulation protected by a waterproof nylon sheet, and a core 358 security mesh panel. A 125x38mm Capping Rail and a 150x75mm Gravel Board complete the assembly, with the gravel board providing a 100mm ground clearance to protect the timber integrity.
• Robust Structural Framework: The 2.4m high fence is supported by formidable 127 x 76mm steel RSJ posts, supplied at a 3300mm length to ensure adequate embedding. These posts are installed via the "Dig In" method into a C20/25 minimum grade concrete foundation with a dig-in depth of 900mm for ultimate stability.
• Optimised for Performance: With a total kit weight of 238.15kg, its substantial mass and a panel density of 71kg/m² are fundamental to its exceptional sound-blocking ability. Panels are firmly secured to the posts with flange hex head wood screws to create a solid, immovable barrier and prevent panel lifting.
• Adaptable Design: The system is perfectly designed for creating long, continuous fence lines and can be configured to accommodate corners of any angle. To ensure the SR1 rating is maintained throughout, corner posts are simply installed adjacent to one another as shown in the system drawings.
• Matching Gates: For consistent protection, we provide 2.4m High AcoustiGuard® SR1 (A1) LPS 1175 Acoustic Gates that integrate effortlessly with the fencing system.
