Insulated, secret-fix, smooth faced wall panel that provides a high-end architectural appearance
Trimapanel® flat is an insulated, secret-fix, smooth faced wall cladding that is quick and easy to install for fast build times. Available in 70mm, 90mm and 120mm insulation thicknesses and bespoke lengths up to 12m to minimise waste and provide U-values down to 0.17W/m2K.
Trimapanel® flat is available in Colorcoat HPS200 Ultra® pre-finished steel in a range of sizes, shapes and colours, and the extensive fabrication options, offers a design flexibility that enables architects to create unique and modern design solutions. The panel can be laid vertically or horizontally. The unique secret-fix joint design allows primary fixings to be hidden from view, which combined with the panel’s flat surface provides outstanding smooth external aesthetics.

Our Platinum® Plus system guarantee offers coverage for up to 30 years. Simply fill in your project details using our easy-to-use online specification tool or contact us directly.
We understand that complex buildings need tailored solutions, so our online specification tool has been designed by our technical team to help you create the right specification to suit the needs of your project, making sure all roofing and cladding components listed and are compatible and perform as a system. It also stores all the specifications you create for ease of access in ‘my projects’.
Creating a Platinum® Plus specification give you free access to our technical team that will support you from design to completion – including those all-important final checks during installation.
Platinum® Plus incorporates only the highest quality components that are designed to do what they say but also provide you with unrivalled choice and flexibility in the specification of your building envelope. The many benefits and reassurance it provides is what sets it apart from all other guarantees, making it the number one choice for complete peace of mind to truly lower the cost of ownership throughout the life of the building.
The Platinum Plus system guarantee needs to be registered by the specifier prior to the tender package being distributed. To find out more click here, alternatively please contact our technical team so that we can help you to guarantee the longevity of your building on +44 (0) 1244 892199.
The Trimapanel® flat system complies with the minimum requirements of the Conservation of Fuel and Power sections of the Building Regulations, Approved Document Part L2, England and Wales and Technical Handbook – Scotland. The panel construction offers highly consistent insulation performance, and the site-formed junctions provide a practical and effective method of ensuring good thermal performance.
*Tata Steel figures computer modelled in accordance with EN ISO 10211, as stated in MCRMA Technical Note 14.
The Trimapanel® flat system has been tested to LPS1181-1 and is LPCB approved to both Grades EXT-B and EXT-A. Fire resistance performance of 15 mins insulation and 4 hours integrity is also achievable with enhance fixing and methods, contact the technical department for details. The internal surface of the panel complies with Class ‘O’ in accordance with the Building Regulations when tested to BS 476 Parts 6 & 7 and also achieves a Class B s2 rating in accordance with EN 13501-1.
Following rigorous structural and fire performance testing with FM Global, Trimapanel® flat panels have achieved FM Approvals certification to the following stringent standards:
4480: Class 1 Insulated wall and ceiling panels 4481: Class 1 Exterior wall systems (unlimited height)
Specifying and installing FM Approved products will provides assurance that the products have been objectively tested and confirm to the highest international standards. FM Approved roof and wall panel’s means you can be confident that your building envelope will withstand a broad range of fire and environmental risks, and be safe throughout its lifecycle.
The acoustic performance of the Trimapanel® flat system has been predicted using software developed by the Department of Applied Acoustics, University of Salford, under a research contract funded by the Metal Cladding and Roofing Manufacturers Association (MCRMA). The results below are based on a 70mm core.
