A high-strength, low thermal conductivity Structural Thermal Break material
STRUKTRA™ TBK
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?
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.
STRUKTRA™ TBK can be used in a wide variety of applications where there is a structural requirement for thermal insolation:
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.

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.
