1950mm Catnic CG90/100 Cavity Wall Lintel

Catnic CG90/100 Cavity Wall Lintel 1950mm

The Catnic CG90/100 Cavity Wall Lintel 1950mm is a standard duty structural steel lintel designed to provide dependable support over wider masonry openings in cavity wall construction. Engineered for cavity widths 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 high-quality galvanised steel with a durable powder-coated finish, the Catnic CG90/100 lintel offers excellent resistance to corrosion and long-term performance in demanding site conditions. Its integrated insulation core helps to reduce cold bridging across the cavity, improving the thermal performance of the wall system and supporting compliance with current UK building regulations.

The lintel’s open-back profile allows continuous masonry construction of both the inner and outer leaves, ensuring consistent load distribution and simplifying installation. At 1950mm , this lintel is particularly well suited for larger spans such as wide window openings, patio doors or extended apertures that require robust structural support without compromising on thermal performance.

This Catnic lintel also incorporates a built-in damp proof course (DPC) and integral plaster key, reducing the need for additional components and helping streamline the construction process on site.
