What is the Birtley CB90 Cavity Wall Lintel 1800mm?
Birtley CB90 Cavity Wall Lintel 1800mm is a standard-duty structural component designed for cavity walls ranging from 90mm to 105mm in width. It provides horizontal load-bearing support in wall openings such as windows and doors, efficiently transferring structural loads to adjacent vertical supports.
Enhanced with Supergalv hot-dip galvanisation, the lintel boasts a robust 65µm zinc coating, which offers 50% greater corrosion resistance compared to standard coatings, meeting the stringent requirements of BS EN ISO 1461:2009. This feature ensures exceptional durability and reduced maintenance, particularly in moisture-prone or corrosive environments.
Additionally, the integration of expanded polystyrene insulation improves the thermal performance of cavity walls, reducing heat transfer and achieving a remarkable 55% reduction in thermal bridging relative to SAP default values. SAP, or the Standard Assessment Procedure, is a government-endorsed methodology in the UK used to assess the energy performance of residential buildings by calculating heat losses, energy efficiency, and carbon emissions. By significantly surpassing these baseline values, the lintel contributes to superior energy efficiency and sustainability in modern building designs.
Birtley CB90 Cavity Wall Lintel's baseplate-free design further enhances adaptability and load distribution, while the integrated plaster key on the inner leaf simplifies finishing processes by improving plaster adherence, making it a versatile and efficient solution for residential construction.
Where is the Birtley CB90 Cavity Wall Lintel 1800mm Used?
- Residential, commercial, and industrial construction projects where cavity wall structures are utilised.
- Architectural designs that incorporate openings, such as windows and doorways.
- Energy-conscious building projects, where thermal efficiency and reduced thermal bridging are critical.
Please Note: This lintel is unsuitable for point loads and incompatible with concrete floors.
