External trapezoidal insulated roof and wall panel system

Trisomet® is an insulated panel system suitable for both roof and wall cladding applications. A factory engineered one-fix component ensures consistant thermal and air tightness performance, and speed of installation. The wide spaced trapezoidal steel external skin provides optimum performance for water drainage, strength and walkability.

Manufactured in factory conditions operating to quality management standard BS EN ISO 9001:2015, environmental management standard BS EN ISO 14001: 2015 and occupational health and safety management standard BS EN ISO 45001:2018. Full traceability of all component materials and certified ‘very good’ to BRE’s responsible sourcing standard BES 6001.
 

Platinum® Plus 25 year system guarantee.

Trisomet® FW and a range of system components including fixings, wall lights, sealants and fillers are available with our Platinum® Plus system guarantee providing a complete building envelope solution guarantee for 25 years. Colorcoat Prisma® pre-finished steel is used as standard, offering long-term performance with the Confidex® Guarantee and providing peace of mind for up to 40 years.

Fire Resistance

Building Systems UK have a library of test evidence in accordance with BS 476 part 22 and BS EN 1364-1. Design options for the application of Trisomet® panel system are considerable therefore to obtain the correct specification to meet your project needs, please contact our technical department or obtain a specification through the SPECGEN tool.

Reaction to fire

Trisomet® panels are classified B-s2,d0 according to the European Reaction to Fire classification system (Euroclasses) BS EN 13501–1: 2018 when tested on the standard internal face of the product.

Roof exposure to fire

The Trisomet® roof system meets BROOF(t4) in accordance with BS EN 1187.

Third party accreditations

• LPCB (Loss Prevention Certification Board) approval to LPS 1181 Part 1.2 certified to EXT-B for all thicknesses.
• Approved to FM Class 4880, 4881 and 4471 to an unlimited wall height.
• Specification is critical for compliance. Our Technical Team can help you with your specification drafting - or you can use our SPECGEN tool.

Thermal performance

Trisomet® complies with the minimum requirements of the conservation of fuel and power sections of the Building Regulations for England and Wales (Part L2) and Scotland (Technical Handbook Section 6 Energy). The panel construction offers highly consistent insulation performance, and the site-formed junctions provide a practical and effective method of ensuring good thermal performance. Thermal performance is calculated in accordance with BS EN 14509 with U-values computer modelled in accordance with EN ISO 10211 and assessed using the methods and conventions set out in the Building Research Establishment’s BR 443.

Air-tightness

In accordance with product standard BS EN 14509, the air tightness of a system should be tested to BS EN 12114. In line with these testing requirements our laboratory tests evidenced that the Trisomet® system has an air leakage as low as 0.43 m3/h/m2.

Weatherability and water penetration

In accordance with product standard BS EN 14509, the watertightness of the Trisomet® system is tested to EN 12865. The standard advises that the system should achieve watertightness to a pressure of 600 Pa for normal conditions. In accordance with such testing requirements our laboratory testing shows evidence that the Trisomet® system is water-tight up to a pressure of 1200 Pa which far surpasses this requirement.

Acoustic performance

The sound reduction performance of the Trisomet® system has been predicted using software developed by Building Systems UK. The results below are based on a 120mm panel thickness.
