Birtley Standard Duty Steel Cavity Wall Lintel 3300mm x 177mm - CB150

The CB150 is a standard duty cavity wall lintel designed for cavity sizes between 150mm and 170mm. This lintel is engineered to provide reliable support for load-bearing walls while improving thermal efficiency with factory-fitted insulation. Key Features: Cavity Size: Suitable for cavity widths of 150mm to 170mm. Insulation: Includes expanded polystyrene insulation, helping to reduce thermal bridging and improve the energy efficiency of the structure. Baseplate-Free Design: The absence of a baseplate enhances structural flexibility and performance. Galvanization: Features Supergalv coating, offering superior protection against corrosion and enhancing the life expectancy of the product. Post-Fabrication Galvanizing: Ensures complete coverage and eliminates surfaces with inferior paint protection, resulting in enhanced durability. Propping: Lintels over 1500mm in length must be propped until masonry is fully loaded and cured for safety and structural integrity. This lintel is ideal for standard duty applications requiring robust thermal performance and structural support in larger cavity walls.
