STRUKTRA™ TBF
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 18m.
Why choose STRUKTRA™
Structural Thermal Breaks?
Constantly driven by Engineering Excellence,
we continue to lead the way in the development
of the Structural Thermal Break Plate market.
Changes in Legislation in response to climate change and energy saving, has meant that reducing energy loss and the risk of condensation has grown in importance - as has the construction industries' preference for Farrat Structural Thermal Breaks.
Accreditations & Certifications:
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

Quotations
Orders & manufacturing
Farrat Structural Thermal Breaks are bespoke products so early procurement is recommended. We aim to start manufacturing within 3 working days from an order being placed.
Prior to fabrication a fully dimensioned drawing is normally required for each type of plate with a unique project reference.
Prior to delivery all Farrat Structural Thermal Breaks are labelled with the fabricator’s drawing reference. Fabrication is undertaken in accordance with our ISO 9001 and ISO14001 accreditations.
