Birtley Cavity Lintel 50mm CB50
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.
Lintel Features:
- Extended Service Life: Supergalv coating greatly extends the service life of the Birtley CB50 lintel, providing a robust solution for your construction needs.
- Comprehensive Paint Protection: Post-fabrication galvanisation ensures thorough paint protection, increasing its aesthetic appeal and durability.
- Reduced Thermal Bridging: Elimination of baseplate and factory insulation reduces thermal bridging contributing towards energy efficiency gains, contributing towards green building performance.
- Tailored Design: These frames are tailored specifically for cavities ranging between 50mm and 65mm in depth.
- Available in span lengths from 750mm to 4800mm.
Installation Requirements:
- Bed fully on bricklaying mortar
- Must be used with a cavity tray - External walls only
- Not suitable for point loads or concrete floors
- 150mm Minimum end bearing
