Catnic CG90/100 Cavity Wall Lintel 2400mm | Supreme Merchants

The Catnic CG90/100 Cavity Wall Lintel 2400mm is a standard duty structural steel lintel engineered to provide dependable support over large 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 efficiency for a wide range of residential and light commercial building applications.

Manufactured from galvanised steel with a protective powder-coated finish, the Catnic CG90/100 lintel offers excellent corrosion resistance and long-term performance on site. Its integrated insulation core helps to reduce cold bridging across the cavity wall, improving the thermal performance of the structure and supporting compliance with modern UK building regulations.

The lintel’s open-back profile allows for continuous masonry build-up of both the inner and outer leaves, ensuring even load distribution and simplifying installation. With an extended span of 2400mm, this lintel is well suited to larger openings such as wide patio doors, expansive window assemblies, or multi-bay apertures commonly specified in modern domestic and commercial builds.

This Catnic lintel also incorporates a built-in damp proof course (DPC) and an integral plaster key, reducing the need for additional materials and helping streamline the installation process. Supplied by Supreme Merchants, this lintel is part of a comprehensive range of sizes, ensuring reliable specification across multiple openings within the same project.
