EN-Construction-Overview of Trimapanel® FTF

trimapanel ftf tata steel construction ford

Insulated, secret-fix, flat panel for a modern architectural appearance

Trimapanel® FTF (frame-to-frame) system is an enhanced panel with the ability to span up to 8m, enabling the product to run horizontally between main frame steelwork or alternatively vertically between base and eaves rails.

This not only removes the cost of a secondary steelwork support system but reduces the installation programme and removes dust traps, providing a clean and attractive finish to the inside of the building.

Trimapanel® FTF is an insulated, secret-fix architectural wall cladding system that is quick and easy to install for fast build times. The system comprises a pre-finished steel liner profile, a LPCB Approved PIR insulation core and a micro-rib pre-finished steel external weathering profile. Available in a range of colours, the panels come in 90mm and 120mm insulation thicknesses and provide U-values down to 0.17W/m2K.

EN-Construction-Benefits of Trimapanel® FTF


Provides modern, high-end aesthetics

  • The enhanced panel has the ability to span up to 8m, removing the need for secondary steelwork.
  • Unique secret-fix joint design allows primary fixings to be hidden from view and, together with the micro-rib profile, provides flat external aesthetics.
  • Flexible design allows vertical and horizontal panel installation.
  • Available with a wide range of flashing options, ancillaries, integrated window, and fabricated corner and curved panel options.
  • Available with Colorcoat® High Reflect finish to the internal face.

Independent product verification for risk free specification

Excellent sustainability credentials

  • Lower air permeability of the system reduces energy costs, carbon emission rates and facilitates compliance with Building Regulations (Part L2 & TH 6).
  • Full traceability of all component materials and certified ‘very good’ to BRE’s responsible sourcing standard BES 6001.

Performance guaranteed

EN-Construction-Thermal and fire information of Trimapanel® FTF

Thermal and fire information

The Trimapanel® FTF 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.  

Thickness (mm) U-value (W/m2K)*
90 0.24
120 0.17


*Tata Steel figures computer modelled in accordance with EN ISO 10211, as stated in MCRMA Technical Note 14.

Fire safety

The Trimapanel® FTF system has been tested to LPS1181-1 and is LPCB approved to Grade EXT-B.

The internal surface of the panel also complies with a Class B s2 d0 rating in accordance with BS EN 13501-1.

EN-Construction-Acoustic performance of Trimapanel® FTF

Acoustic performance

The acoustic performance of the Trimapanel® micro-rib 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 90mm core.

Frequency (Hz) SRI Values (dB)* Frequency (Hz) SRI Values (dB)*
100 12.9 800 28.1
125 14.5 1,000 29.8
160 16.2 1,250 31.6
