Catnic CG90/100 Cavity Wall Lintel 1050mm

The Catnic CG90/100 Cavity Wall Lintel (1050mm) is a high-quality structural steel lintel designed to provide dependable support over door and window openings in standard cavity wall construction. Engineered for strength, durability, and thermal efficiency, this lintel is suitable for residential and light commercial building projects where consistent performance is required.

Manufactured from galvanised steel with a durable powder-coated finish, the Catnic CG90/100 lintel offers excellent resistance to corrosion and site conditions. Its integrated insulation core helps to reduce cold bridging and improve the thermal performance of the building envelope, supporting compliance with modern UK Building Regulations and energy-efficiency standards.

The CG90/100 profile is designed 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, simplifying installation and ensuring even load distribution above openings.

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