Farrat is first to market with an A2 Fire Rated Structural Thermal Break material

Farrat has unveiled the markets first A2 Fire Rated Structural Thermal Break ‘Farrat TBF’ this week, following 12 months of research and development in consultation with Salford and Manchester Universities, material scientists and specialist raw material producers.

Farrat TBF is a very limited combustibility Structural Thermal Break material designed to maintain full structural integrity in the event of fire.

Alongside its limited combustibility, the new Farrat TBF material stands alongside the markets best performing thermal insulators, with very high compressive strength and low thermal conductivity – preventing thermal bridges from forming between structural connections and mitigating against the risk of condensation, mould or corrosion.

Farrat TBF

Farrat TBF has been independently tested and verified to the latest industry standards, with a limited combustible calorific rating achieved to EN 1716.

Farrat TBF is verified to maintain its very high structural performance and compressive strength to 500° under EN ISO 604 and is consequently compliant for use under Document B Building Regulations for buildings above 18m.

Chris Lister, Commercial Manager at Farrat

“The addition of Farrat TBF to our Structural Thermal break range is in response to several enquiries from our clients regarding a fire-safe thermal break product,” explains Chris Lister, Commercial Manager for Thermal Products.

“The intention is that Farrat TBF acts as a reliable, effective and readily-available material for fabricators and designers that are looking to meet multiple building regulations relating to fire, heat loss and energy performance with the one Structural Thermal Break product. We expected Farrat TBF to be favoured and especially suitable for thermally insulating structural connections on high-rise developments and buildings above 18m.”

Farrat TBF is available for procurement worldwide from November 1st 2019 and is already set to be used in products around the UK.

Farrat supply Structural Thermal Breaks to insulate connections across a 15,000t steelwork package, being erected at the new Edinburgh St James retail scheme

Edinburgh St James with egg shaped W Hotel

Edinburgh St James is one of the most significant construction and regeneration projects currently under way in the UK and the largest city centre development Edinburgh has seen for decades.

The £1bn project is replacing a 1960s shopping centre with 79,000m² of new retail space, alongside a new five-star W Hotel, an Aparthotel, 152 prime residential apartments, more than 30 restaurants and the city’s first Everyman Cinema.

Numerous column grid patterns requiring hundreds of tonnes of transfer structures, are helping to create the large retail-led mixed-use scheme, with a steelwork package totalling 15,000t of steel being fabricated by the appointed steelwork contractor BHC.

Following specification by the Architect, Farrat are set to supply over £90k of Farrat TBK Structural Thermal Breaks to thermally separate steel connections across buildings in the project.

Thermally insulating steelwork at the Centre for Environment, Fisheries and Aquaculture Science (Cefas)

CEFAS will incorporate an exposed steel frame that will insulated using farrat structural thermal breaks

Farrat are currently helping to deliver a cost-efficient and sustainable HQ building for the Centre for Environment, Fisheries and Aquaculture Science (Cefas) by thermally insulating the exposed steel frame using Farrat Structural Thermal Breaks.

Based in the Suffolk, the UK marine science agency Cefas (The Centre for Environment, Fisheries and Aquaculture Science) is constructing a new £18.3M contemporary headquarters building. The new headquarters will be a sustainable steel-framed landmark and form a central element of a much larger scheme that also includes the phased floor-by-floor refurbishment of an existing 1980s laboratory building.

The building has a composite design with steelwork supporting metal decking and a concrete topping. Most of the steel frame is based around a regular 6m column spacing, with internal spans of up to 12m.

This was deemed sufficient to provide the new building with modern open-plan office and meeting room spaces.

Farrat were recently contacted by the steelwork contractor to help minimise the risk of thermal bridges forming at several different penetrations and transitions in the building envelope.

Independent Review of Building Regulations and Fire Safety

INDEPENDENT REVIEW OF DEC 2018 AMENDMENT TO BUILDINGS REGULATIONS ‘SI 2018/1230’: USE OF NON COMBUSTIBLE MATERIALS

February 14, 2019
Author: Chris Lister, Commercial Manager

Synopsis of amendment

Following the recent amendment to the Building Regulations for Fire (England & Wales) SI 2018/1230 Farrat have been looking at the implications for Structural Thermal Break materials in the new legislation.

The statutory Instrument, issued in Dec 2018 sets out the effective prohibition of combustible materials in the external walls of high rise residential buildings over 18 meters. The amendment implements these changes via explicit regulation rather than guidance, making it an effective ban on any materials not reaching the prescribed certified standard.

The standard for prescribing performance in this case is BS EN 13501-1:2007+A1:2009 entitled “Fire classification of construction products and building elements. Classification using test data from reaction to fire tests” The prescribed level of performance required under this standard for use over 18 meters is European Classification A2-s1, d0 or A1.

BS EN 13501-1 defines the classes A1 and A2 as follows:

  • Class A1 will not contribute in any stage of the fire, including the fully developed fire.
  • Class A2 Will not significantly contribute to the fire load and the fire growth in a fully developed fire

The characteristics “s” and “d” are defined as follows:

  • s1 Weak or no smoke
  • s2 Medium Smoke
  • s3 High Smoke
  • d0 No dripping at all
  • d1 Slow dripping recorded
  • d2 High dripping recorded

The amendment only recognises classifications from European Norm standard. The older British Standard classification, which was recognised in previous guidance, is not included in the new regulation.

The New regulation applies to the building external envelope or specified attachments such as, balconies, bris solei or solar panels on ‘relevant’ dwellings, residential or institutional buildings above 18 meters or 6 storeys. Where the building is a hotel or hostel, boarding house or any other building type above 18 meters the regulations revert to the current Approved Document B requirements for fire of limited combustibility A2,-s3, d2 or better.

Within the new regulation for ‘relevant’ buildings above 18 meters, some building elements of the external envelope are exempt from the A1 & A2 fire performance rating.

This exemption includes door and window frames, glazing, fixings, gaskets and significantly for Farrat, thermal break materials.

Significance of the amendment to Building Regulations for Structural Thermal Breaks

Following their exemption from the recently amended standard for a fire classification, Structural Thermal Break materials, as currently supplied into the UK construction sector and deemed to be for the purpose of meeting the thermal bridging requirements of Approved Document L, can continue to be used under their existing limitations.

However, as with previous base line regulatory exemption, where building designers identify fire performance of construction materials as a higher significance factor, the testing and classification of all component’s planned for use will come under scrutiny.

To this end, alongside the continued development of new materials with Structural and Thermal properties, performance in respect of fire has become a main element in product manufacturers list of required characteristics.

As with all insulating materials there is generally a trade-off between insulation value and structural integrity. In the field of structural thermal breaks this balance is critical. Where structural performance is elevated to pole position, the goal is to achieve as good a thermal conductivity as possible without compromising structural properties.

With the introduction of fire into the equation the balance becomes three way, with Structural performance required to be maintained in the event of a fire whilst still functioning as a thermal break under everyday conditions.

The development of a new Structural Thermal Break material by Farrat has achieved this.

Farrat has utilised it’s full material R&D capabilities to develop the UK’s first Fire-Resistant Structural Thermal Break material: Farrat TBF.

Farrat Thermal Breaks reduce energy loss in London’s new ‘City Cluster’

Londons new City Cluster

22 Bishopsgate is one of 13 major build projects expected to change London’s skyline by 2026.

Designed by PLP Architecture, 22 or ‘Twentytwo’ Bishopsgate stands  278 metres tall as the City of London’s tallest tower within the financial districts new ‘City Cluster‘. The tower provides over 1.2 million sq ft of office space and can accommodate up to four tenants on each of the 62 floors.

Over 17,000 tonnes of superstructure structural steelwork and metal decking was designed and fabricated for construction by Severfieldwho approached Farrat during fabrication to supply a suitable solution to mitigate against thermal bridging between connections.

Superelevations, axial shortening and complex geometrical dilemmas presented challenges on this project, so Farrat worked closely with Severfield to manufacture a package of structural thermal breaks in various sizes, shapes and thicknesses to fit seamlessly into design details and meet specification.

Farrat’s load-bearing structural thermal break material with the highest levels of compressive strength and thermal insulation, was used between steel-to-steel connections to prevent thermal transfer from the exterior of the structure into the internal structure via the steel framework.

Farrat thermal break plates were also used in steel-to-concrete applications to greatly reduce heat loss into the concrete slab, providing better insulation for the structure overall.
