Catnic CG90/100 Cavity Wall Lintel 2100mm | Supreme Merchants

The Catnic CG90/100 Cavity Wall Lintel (2100mm) is a standard-duty structural steel lintel engineered to provide dependable support over wide masonry openings in cavity wall construction. Designed for use in walls with a cavity width between 90mm and 105mm, this lintel delivers strength, durability, and thermal performance for a variety of residential and light commercial building applications.

Manufactured from galvanised steel with a protective powder-coated finish, the Catnic CG90/100 lintel offers excellent resistance to corrosion and long-term performance in typical construction environments. Its integrated insulation core helps to reduce cold bridging across the wall cavity, improving the thermal efficiency of the building envelope and supporting compliance with modern UK energy standards.

The open-back profile allows continuous masonry construction of both the inner and outer leaf, ensuring consistent load distribution and simplifying installation. At 2100mm, this lintel is particularly suitable for large spans such as extended window openings, wide doorways, or bi-fold/patio door apertures that require robust structural support.

Incorporating a built-in damp proof course (DPC) and an integral plaster key, this lintel reduces the need for additional components and helps to streamline on-site installation. Supreme Merchants supplies Catnic lintels as part of a complete range of sizes to ensure consistent specification across multiple openings within a project.
