A site assembled metal roof cladding system.
Trisobuild™ Systems comprise of a pre-finished steel trapezoidal liner profile, a Platinum Plus® approved spacer system, an insulation layer and a Colorcoat® pre-finished steel external weathering profile. A comprehensive range of internal and external profiles are available, all of which have been comprehensively tested, and third party assessed for structural capability by the Steel Construction Institute (SCI).
Tata Steel has created a range of Trisobuild™ System solutions that can achieve high levels of thermal, air-tightness, fire and acoustic performance, to meet the needs of any building envelope application. The systems ancillary components (i.e. fixings, sealants, roof lights, fall arrest, gutters and walkways) are specified from a range of approved Platinum Plus® System Guarantee suppliers who are selected on the basis of their ability to meet stringent technical criteria combined with 25 year product durability. Manufactured in factory conditions operating to BS EN ISO 9001.

Manufacturing tolerance (to BS EN 14509):
Trisobuild™ R and RWL Systems when used as a roof achieve a Grade AA rating in accordance with BS 476-3, which tests for external surface spread of flame and fire penetration or are “deemed to satisfy without the need for testing” in accordance with Commission Decision 200/553/EC. The Colorcoat® pre-finished steel products used within the Trisobuild™ System meet the requirements the Building Regulations Approved Document B for internal and external surfaces. Trisobuild™ Systems can also offer a Grade EXT-B approval by the LPCB.
All roof systems are capable of being laid at a 4° roof pitch (with the exception of the 13.5/3 profile which is limited to 10°).
In laboratory tests in accordance with BS EN 12114, the sealed panel shows evidence of air leakage as low as 0.30 m³/h/m². A practical expectation for a finished building, with effective sealing at all junctions would be 3–5 m³/h/m². However enhanced detailing practises on large shed buildings can realise air leakage performance figures of less than 3 m³/h/m².
The Trisobuild™ R and RWL Systems are a sustainable solution with responsible sourcing and traceability of all component materials. All steel elements are produced within the UK Tata Steel’s steel production, strip processing, galvanizing, coating and profiling facilities. In addition the system’s carbon footprint is further minimised by the manufacturing process being situated adjacent to Colorcoat® pre-finished steel production facility. All steel elements are 100% recyclable back into new steel products, without loss of quality.
