STRUKTRA™ TBK
Structural Thermal Breaks
STRUKTRA™ TBK is our premium grade material with very high compressive strength characteristics combined with a very low thermal conductivity.
- STRUKTRA™ only use Structural Thermal Break materials specifically developed for use within the building envelope.
- STRUKTRA™ TBK is fully certified to ensure that designers and clients have confidence in the product when used in structural connections.
- STRUKTRA™ TBK can be supplied as cut to size pads or strips, with a bespoke number of holes precision waterjet cut, according to the customer’s requirements or specification.
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.
Structural applications
Farrat Structural Thermal Breaks are high-performance thermal insulators used between horizontal and vertical connections of internal and external elements to prevent thermal or cold bridging.
Variety of application
STRUKTRA™ TBK can be used in a wide variety of applications where there is a structural requirement for thermal insolation:
New build and refurbishment projects
STRUKTRA™ TBK can be used in new build and refurbishment projects within the following building element examples:
- Facade system connections to primary frames
- Brise soleil and signage
- Roof parapets
- Connection of external to internal primary building elements
- Balconies
- Staircases
- Isolation of sub-structure and basement elements
- Connections to existing structures
Testing
Independent material testing was undertaken in Germany by an Institute with DAkks Certification.

Quotations
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/CE-marked 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/CE mark as well as ISO 9001:2015 and ISO14001:2015 certifications. This includes:
- Checking the drawings against the quotation and customer order
- 4-eyes check of the CNC programme
- Visual and dimensional inspection of the manufactured products
- 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.
