Catnic CG90/100 Cavity Wall Lintel 1350mm | Supreme Merchants

The Catnic CG90/100 Cavity Wall Lintel 1350mmis a standard duty structural steel lintel designed to provide reliable support over door and window openings in cavity wall construction. Suitable for residential and light commercial applications, this lintel offers a combination of strength, durability, and thermal efficiency to meet modern building requirements.

Manufactured from galvanised steel and finished with a protective powder coating, the Catnic CG90/100 lintel provides excellent resistance to corrosion and site conditions. Its integrated insulation core helps to reduce cold bridging and improve the overall thermal performance of the building envelope, supporting compliance with current UK Building Regulations and energy efficiency standards.

The CG90/100 profile is engineered for cavity widths between 90mm and 105mm, making it ideal for many common UK construction specifications. The open-back design allows continuous construction of both the inner and outer masonry leaves, ensuring consistent load distribution while simplifying installation on site.

This lintel incorporates a built-in damp proof course (DPC) and plaster key, reducing the need for additional components and helping to improve installation efficiency. It is suitable for use with brickwork, blockwork, and rendered finishes, providing versatility across a wide range of building projects.

Supplied by Supreme Merchants, this Catnic cavity wall lintel forms part of a complete range of sizes, enabling consistent specification across multiple openings within the same development.
