Meet the Birtley Cavity Lintel 50mm CB50, an innovative standard 50mm cavity lintel that redefines durability and insulation. Tailored specifically for cavities between 50-65mm with outer leaves of 100mm and inner leaves of 100mm. This Birtley CB50 lintel is not designed for point loads or concrete floors but its performance in other crucial aspects stands out. It boasts a Supergalv coating for longevity and protection.

Post-fabrication galvanisation ensures that every inch of the steel lintel is protected from issues associated with inferior paint coverage. The absence of baseplate combined with factory-fitted insulation reduces problems such as thermal bridging, and this boosts energy efficiency.
