Catnic CG90/100 Cavity Wall Lintel 1650mm | Supreme Merchants

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.
