Catnic’s Thermally Broken Lintel (TBL) range has achieved British Board of Agrément (BBA) Approval.
The independent testing and certification also confirms the lintels’ structural and fire performance as well as durability of at least 60 years. The lintels included in the BBA Approval are suitable for cavities between 90 and 165mm and are available in lengths of 750 to 4,800mm.
Catnic TBLs provide a full thermal break to reduce the thermal bridging between the inside and outside of the building. The Catnic TBL range achieves Building Research Establishment (BRE) certified energy transmittance psi values of 0.02 to 0.05 W/mK, surpassing the requirements of SAP 2012 Appendix Q.
Featuring a composite design, Catnic TBLs provide a complete thermal break between the inner and outer leaf of a cavity wall. The lintels are manufactured from powder coated galvanised steel bonded to a high-density insulating core. In addition, they can be installed in exactly the same way as a traditional lintel, with the same safe working loads as the equivalent Catnic cavity wall lintel.
Richard Price, Technical Director at Catnic said: “Catnic has always recognised the value that independent testing and certification has for customers, being the first steel lintel manufacturer to achieve both BBA approval and the British Standards Kitemark to BS 5977. The BBA Approval of our complete range of TBLs ensures customers have all the information needed, and the assurance that they are indeed making a robust specification.”
