900mm Catnic CG70/100 Cavity Wall Lintel

900mm Catnic Cougar Open Back Cavity Wall Standard Duty Lintel CG70/100

The Catnic Cougar Open Back Cavity Wall Standard Duty Lintel (CG70/100) is a high-quality structural steel lintel designed to provide dependable support over openings in cavity wall construction. Engineered with Catnic’s trusted Cougar profile, this lintel offers strength, durability, and thermal performance for use in brick and block cavity walls where standard duty structural support is required.

Manufactured from galvanised steel with a durable powder-coated finish, the Catnic Cougar lintel provides excellent resistance to corrosion and long-term performance in external environments. Its open-back design allows continued build-up of both inner and outer masonry leaves, ensuring even load distribution across door and window openings while simplifying on-site installation.

This lintel incorporates integrated insulation , a built-in damp proof course (DPC) , and an integral plaster key , helping to reduce cold bridging and streamline finishing work. These built-in features mean fewer additional materials are needed on site, improving build efficiency and overall thermal performance of the wall system.

Catnic Cougar lintels are designed to support uniform masonry loads as well as typical timber floor and roof loads in standard duty applications. They are suitable for both new build and renovation projects where reliable lintel performance and thermal efficiency are essential.
