Farrat supply facade thermal breaks for new flagship Adidas store

Farrat thermal breaks used to thermally isolate the facade retention steelwork at new Adidas store

A joint venture between Grosvenor Britain & Ireland and Stow Capital Partners, the 425 Oxford Street retail scheme involves the reconfiguration and extension of the lower five floors of a 10-storey building in the West End shopping district, to create a 45,000 sq. ft flagship unit for Adidas.

The redevelopment features new double-height windows on the ground floor and an extensive glass frontage.

To prevent heat loss through the building facade, Farrat have supplied Structural Thermal Breaks for use within the facade retention steelwork. The facade thermal breaks will act as a thermal insulator and avert thermal or cold bridging.

This is a simple, economical and extremely effective solution to meeting Building Regulations by way of reducing the risk of internal condensation.

Farrat Structural Thermal Breaks can be used in a wide variety of applications where there is a structural requirement of thermal insulation, including:

  • Steel to steel
  • Steel to concrete / masonry
  • Steel to timber
  • Concrete to concrete


A full list of typical applications can be found here.

Handover of the bespoke scheme to Adidas is targeted for Spring 2019.

The Post Building is a mixed-use redevelopment of the former Royal Mail Sorting Office, located in London’s vibrant Knowledge Quarter.

A combination of carefully curated office, retail and food & beverage amenities, the redevelopment was designed by AHMM Architects and is currently being delivered by Laing O’Rourke. The lower half of the existing frame is retained and a new core and series of intermediate mezzanine levels will be inserted into the centre of its plan. Key structural features include floor to ceiling heights of up to six metres, natural light from all sides and private roof terraces to every floor.

The project targets sustainability ratings of BREEAM Excellent, LEED® Gold and EPC B by incorporating specialist materials and technologies into the design that promote the health and comfort of building occupants and improve building performance.

Farrat were approached early in the construction by the steelwork fabricator to supply structural thermal breaks for use between several connections within the structural frame.

Farrat Structural Thermal Breaks are incorporated into connections to reduce energy loss and the risk of condensation. They are frequently used as thermal insulators within many building applications to improve the energy performance of buildings.

We recommended our high-strength TBK Structural Thermal Break material, as this offers the lowest thermal conductivity and is certificated by the British Board of Agrément (BBA). Farrat is also a member of BRE’s Certified Thermal Product Scheme. Plates of various sizes were precision cut at our UK manufacturing facility and dispatched to site.

The Post Building is due for completion in 2018.

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.

Steel frame complete on the latest King’s Cross commercial block ‘Building S2’

Severfield plc have erected 1,700t of steelwork, integrating Farrat TBK 25 Structural Thermal Breaks, for the latest steel-framed building to top-out at the King’s Cross development ‘Building S2’.

The 12-storey building will offer 23,000m2 of commercial space on Handyside Street and is set to achieve a BREEAM ‘Outstanding’ environmental rating.

Steel-framed buildings increasingly achieve high ratings after being assessed under BREEAM. Steel offers sustainability credentials through the whole life-cycle of a building, and is an excellent choice of framing material – a recent survey by Building magazine, sponsored by Steel for Life, identified that over 66% of multi-storey, non-domestic buildings are framed in structural steel, making it the preferred framing solution for many of the UK’s structures.

Farrat Structural Thermal Breaks are high-performance thermal insulators,  used between steel-to-steel and steel-to-concrete connections. Manufactured from materials specifically developed for use within the building envelope, both our Farrat TBK and Farrat TBL Structural Thermal Break materials have British Board of Agrement Certification (BBA), to ensure that designers and engineers have complete confidence in the product when used in structural connections.

Steel connections that include structural thermal break plates should be designed in accordance with the relevant design standards (e.g. BS EN 1993-1-8) or industry guidance (e.g. SCI publications). Under the SCI Assessed Product Scheme, the technical data and structural design methodology for Farrat Structural Thermal Breaks has been independently verified by the SCI.
