Catnic Cougar Open Back Cavity Wall Standard Duty Lintel – 1800mm (CG70/100) | Supreme Merchants

The Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel – 1800mm (CG70/100) is a high-quality structural steel lintel designed to provide dependable support over door and window openings in cavity wall construction. Engineered for standard duty applications, this lintel is suitable for cavity widths between 70mm and 100mm, making it ideal for many common UK residential and light commercial building projects.

Manufactured from galvanised steel with a durable powder-coated finish, the Catnic Cougar lintel offers excellent resistance to corrosion and long service life in demanding site conditions. Its open-back profile allows continuous construction of both the inner and outer masonry leaves, ensuring even load distribution while simplifying installation on site.

An integrated insulation core helps to reduce cold bridging across the cavity wall, improving the overall thermal efficiency of the building envelope and supporting compliance with modern energy efficiency standards. This lintel also incorporates a built-in damp proof course (DPC) and an integral plaster key, reducing the need for additional components and helping streamline finishing work.

With a span of 1800mm, this Catnic Cougar lintel is particularly suited to wider window openings, larger doorways, and patio door apertures where reliable structural performance and thermal efficiency are both required. It is designed to support typical masonry loads as well as standard timber floor and roof loads in cavity wall construction.

Supplied by Supreme Merchants, this lintel forms part of the Catnic Cougar CG70/100 range, allowing consistent specification across multiple opening sizes within the same project.
