Farrat Structural Thermal Breaks used to isolate eight-storey steel-framed office block targeting ‘WELL Building Gold Standard’

‘Duke Street’ is an eight-storey office development, which forms part of the much wider St James’s redevelopment – a major 10-year investment programme that will revitalise the renowned central London area with a new public square, offices, retail outlets and high quality residences.

The building will provide 3,234m² of office accommodation, spread over six upper floors with two levels of retail offering 1,034m² of space. The project aims to achieve BREEAM ‘Outstanding’ for its commercial floors, BREEAM ‘Very Good’ for its retail zone, and as a whole, is targeting a WELL Building Gold Standard rating for its shell and core. The latter certification recognises the building has been designed as a healthy and productive space for its future occupants.

Farrat were approached by the Steelwork Contractor to supply thermal breaks to sit between steel connections within the structure. The building’s substructure is formed with concrete, and the main steel frame begins at basement level one, with the majority of the steel frame’s connections via fin plates. The thermal breaks were required to act as thermal insulators within the frame, to reduce the risk of thermal bridging and internal condensation.

Our high-strength Structural Thermal Break material was selected, offering the optimum combination of Compressive Strength and Thermal Conductivity. The plates were then precision-cut to the bespoke length, width and hole configurations required.
