Catnic CG90/100 Cavity Wall Lintel 2700mm | Supreme Merchants

The Catnic CG90/100 Cavity Wall Lintel 2700mm is a standard duty structural steel lintel designed to provide strong and reliable support over very wide openings in cavity wall construction. Engineered for use in walls with a 90mm–105mm cavity, this lintel offers dependable structural performance with thermal efficiency, making it suitable for larger residential and light commercial applications.

Manufactured from galvanised steel with a durable powder-coated finish, the Catnic CG90/100 lintel provides excellent resistance to corrosion and long-term performance in external environments. The open-back design allows continuous build-up of both inner and outer masonry leaves, delivering consistent load distribution and efficient installation on site.

An integrated insulation core minimises cold bridging across the cavity wall, improving thermal performance and helping align with modern energy efficiency standards. The lintel also features a built-in damp proof course (DPC) and an integral plaster key, reducing the need for additional materials and improving installation efficiency.

With an extended length of 2700mm, this lintel is particularly well-suited to applications such as wide patio doors, expansive window runs, or large multi-bay openings where robust support and thermal performance are both required.
