1500mm Catnic CG90/100 Cavity Wall Lintel

Catnic CG90/100 Cavity Wall Lintel 1500mm

The Catnic CG90/100 Cavity Wall Lintel 1500mm is a standard-duty structural steel lintel engineered to provide reliable support over medium-span door and window openings in cavity wall construction. Designed for use in cavity walls with a width of 90mm to 105mm , this lintel combines strength, corrosion resistance, and thermal efficiency to meet the demands of modern UK construction projects.

Manufactured from galvanised steel and finished with a protective powder coat, the Catnic CG90/100 lintel offers excellent resistance to corrosion and long-term durability. Its integrated insulation core minimises cold bridging across the cavity, improving overall thermal performance. The open-back profile allows for continuous masonry build-up on both the inner and outer leaves, ensuring consistent load distribution and simplifying installation.

This 1500mm lintel is suitable for wider domestic openings such as patio doors or large window spans and is commonly specified in both residential and light commercial building projects. It incorporates a built-in damp proof course (DPC) and an integral plaster key, reducing the need for additional components and helping to streamline on-site construction.
