1650mm Catnic CG90/100 Cavity Wall Lintel

Catnic CG90/100 Cavity Wall Lintel 1650mm

The Catnic CG90/100 Cavity Wall Lintel (1650mm) is a standard-duty structural steel lintel engineered to provide dependable support for masonry loads across wider openings in cavity wall construction. Built specifically for cavity walls with widths of 90 mm–105 mm , this lintel delivers strength, durability, and thermal performance suitable for residential and light commercial building projects.

Manufactured from galvanised steel with a powder-coated protective finish, the Catnic CG90/100 lintel resists corrosion and performs reliably in a range of site conditions. Its integrated insulation core helps to minimise cold bridging, improving the thermal performance of the wall system and supporting compliance with modern insulation standards. The open-back profile allows continuous construction of both the inner and outer masonry leaves, simplifying installation while ensuring even load distribution.

This 1650mm lintel is well-suited to larger window spans, patio door openings, and other medium-to-wide aperture applications where extended structural support is required. It also incorporates a built-in damp proof course (DPC) and plaster key, reducing the need for additional materials and helping to streamline the installation process.
