Building Systems has expanded its renowned Trimapanel® family of steel insulated secret-fix architectural wall panels with the launch of Trimapanel® FW (Firewall) – a product designed to meet tomorrow’s standards, today.
UK building regulation fire testing historically references British Standards (BS 476 Part 22), however EN standards represent the harmonised European benchmark, providing a unified, robust framework recognised across international markets. EN 1364-1 resistance to fire testing standard is required to be adopted in the UK market by 2029. In addition the EN 1364-1 standard is more demanding than BS 476 Part 22 with a wider range of conditions providing confidence in real-world performance.
Comprehensive Testing Programme
Trimapanel® FW insulated secret-fix architectural wall panels have been through a robust and extensive testing programme. The EN 1364-1 certification covers:
✓ Both vertical and horizontal panel orientations, ensuring maximum design flexibility.
✓ All module widths, meaning there are no limitations on project scale or geometry.
✓ Large spanning capabilities, offering architects and engineers the opportunity to design open, versatile spaces without compromise.
✓ A variety of unexposed and external paint finishes, proving the panel’s performance is unaffected by different coatings and ensuring confidence across the full aesthetic spectrum.
This breadth of testing sets Trimapanel® FW apart, giving specifiers assurance that performance is consistent regardless of project configuration or finish choice.
Why EN Standards Matter
From 2029, building products and building elements will also need to demonstrate classification to EN 13501-2, which specifies the fire resistance performance of such products. Trimapanel® FW is already geared towards these requirements, ensuring that your specification is future proofed.
Peace of Mind with SPECGEN and Technical Support
To support architects, contractors, and specifiers, Building Systems UK offers SPECGEN, an online specification tool that makes it simple to select Trimapanel® FW, and other products, from Building Systems UK’s range. SPECGEN ensures that the correct performance parameters are incorporated into your specification from the outset, streamlining the design and tendering process.
Our Technical Department are here to offer expert support across a range of design criteria from acoustics to thermal performance and air permeability to carbon performance. We are able to provide bespoke calculation services and an extensive test library. This allows us to collaborate directly with your supply chain including the delivery of efficient boundary wall designs that align with the recommendations of the British Constructional Steelwork Association (BCSA), ensuring both safety and full regulatory compliance.
Future readiness for complete peace of mind
Trimapanel® FW is more than just a new addition to the Trimapanel® range – it’s a statement of future-readiness. By combining architectural appeal with excellent fire performance, the product gives designers, contractors, and building owners complete peace of mind. With EN 1364-1 testing already secured and alignment to EN 13501-2 in place, Trimapanel® FW stands as the clear choice for anyone looking to design with confidence in a changing regulatory environment.
