STRUKTRA™ TBF

A Structural Thermal Break material designed to maintain structural integrity in the event of fire

STRUKTRA™ TBF

Structural Thermal Breaks

STRUKTRA™ TBF is proven to have high compressive strength at a high temperature and low thermal conductivity, allowing designers to meet multiple building regulations relating to fire, heat loss and energy performance with the one structural thermal break product.

STRUKTRA™ TBF has been independently fire tested and verified to the following industry standards:

  • A2,s1,d0 Fire-rated classification to EN 13501-1.
  • Maintains very high structural performance and compressive strength to 500°C under EN ISO 604.
  • Compliant for use under Document B Building Regulations for buildings above 11m.

Structural applications

Farrat Structural Thermal Breaks are high performance thermal insolators used between horizontal and vertical connections of internal and external elements to prevent thermal or cold bridging.

Variety of application

STRUKTRA™ TBF can be used in a wide variety of applications where there is a structural requirement for thermal insolation:

Common interface details

STRUKTRA™ TBF is capable of transferring load in moment and shear connections without creating significant rotation.

STRUKTRA™ TBF can be used in anywhere a penetration or transition exists in a building envelope to improve building performance. Examples include:

  • Structural frames
  • Facade system connections to primary frames
  • Connection of external to internal primary building elements
  • Balconies
  • Staircases
  • Isolation of sub-structure and basement elements
  • Man-safe systems
  • Connections to existing structures
  • Roof plant enclosures - columns
  • Roof parapets
Steel to steel structural frames
Steel to concrete balcony connections
Steel to concrete column bases
Steel to concrete façade systems

Testing

Independent material testing was undertaken in Germany by an Institute with DAkks Certification.

Orders & manufacturing

STRUKTRA™ Farrat’s structural thermal breaks are manufactured to your specific requirements. You send us your drawings and we manufacture them under strict BBA quality control. Depending on quantity, delivery can be next day or usually within 3 working days of order placement.

A fully dimensioned drawing for each plate with a clear project reference is usually required prior to manufacture.

Ensuring that you receive the correct product in time for your installation is an integral part of our service offering and is embedded in our BBA mark as well as ISO 9001:2015 and ISO14001:2015 certifications. This includes:

  1. Checking the drawings against the quotation and customer order
  2. 4-eyes check of the CNC programme
  3. Visual and dimensional inspection of the manufactured products
  4. Each item is then labelled individually so that it can be easily identified on site and traceability back to the manufacturer of the raw material is guaranteed.
