FAQs

What is the purpose of the open-back design?

The open-back design allows for continuous masonry bonding, making the construction process easier and more robust.

What is the purpose of the DPC?

The DPC (Damp Proof Course) prevents moisture from penetrating the wall, protecting the structure from water damage.

What cavity sizes is this lintel suitable for?

The Catnic CG150/100 is designed for 150-165mm cavity walls.

What inner leaf thicknesses does this lintel support?

It supports inner leaf thicknesses of 100–115mm.

How do I determine the correct lintel length?

Consult the manufacturer's datasheet and building plans to determine the required span and load calculations. Make sure to allow for sufficient end bearing on each side of the opening.

Can I cut the lintel to a specific size?

While it is possible to cut the lintel, it is recommended to consult with the manufacturer's guidelines as it may affect its structural integrity.

Where can I find the safe working load for the lintel?

The safe working load can be found on the datasheet, the safe working load is up to 26kN using 150mm end bearings.

Troubleshooting

Lintel is not level after installation.

Check the supporting structure for levelness. Adjust shims as necessary to achieve a level installation.

Cracks appearing in the masonry above the lintel.

Ensure correct end bearing is provided, check for overloading or settlement.

Moisture penetration in the wall.

Verify the DPC is correctly positioned and that there are no gaps or damage to the lintel.

Setup, Compatibility & Care

Preparation: Ensure the cavity wall opening is the correct size for the lintel. Check the datasheet for the appropriate end bearing for the lintel length used.
Installation: Place the lintel on the supporting structure, ensuring it is level. The open-back should face the inner leaf. Ensure sufficient end bearing is provided.
Positioning: Ensure the DPC is correctly positioned to prevent moisture penetration.
Masonry: Build the masonry on top of the lintel, ensuring the load is evenly distributed.
Compatibility: This lintel is compatible with standard cavity wall construction and masonry materials.
Care: Inspect the lintel for any damage before installation. Handle with care to avoid bending or damaging the protective coatings. Store in a dry place before use. Follow the manufacturer's guidelines for cutting or modifying the lintel.
