1200mm Catnic CG70/100 Cavity Wall Lintel

Catnic CG70 Cougar Open Back Cavity Wall Standard Duty Lintel – 1200mm

The Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel (1200mm) is a high-quality structural steel lintel designed to provide reliable support over door and window openings in standard cavity wall construction. Part of Catnic’s Cougar range, this lintel is engineered to combine strength, durability, and thermal performance to meet modern building requirements for residential and light commercial applications.

Manufactured from galvanised steel with a robust powder-coated finish, this lintel delivers excellent corrosion resistance and long-term performance, making it suitable for external masonry use. The open-back profile allows continuous build-up of both the inner and outer masonry leaves, ensuring even load distribution across the opening and simplifying on-site installation.

The Catnic Cougar lintel features integrated insulation to help reduce cold bridging and improve thermal efficiency throughout the wall system. It also incorporates a built-in damp proof course (DPC) and an integral plaster key , reducing the need for additional components and helping to streamline finishing work on site.

With a practical 1200mm span, this lintel is ideal for medium-sized residential window openings, smaller doorways, and a variety of typical cavity wall apertures, providing dependable structural support while enhancing energy performance.
