Window Lintels

Choosing the right window lintel starts with understanding the wall type and the width of the opening. For most modern external walls, cavity lintels are used to support both the inner and outer leaf while maintaining insulation across the cavity. In solid wall construction, box lintels or concrete lintels are typically specified, depending on the load and span.

For smaller openings or internal walls, lighter-duty lintels such as single leaf or angle lintels may be sufficient. Larger window openings, or those supporting floor loads or roof structures, will require heavier-duty solutions and careful consideration of bearing length and load conditions.

We stock a wide range of window lintels from leading UK manufacturers, covering common domestic and light commercial applications. Whether you’re working with brick, block, or a combination of both, selecting the correct lintel ensures structural stability and long-term performance.

If you’re unsure which type is suitable, it’s worth reviewing the wall build-up and load requirements before selecting. For more detailed guidance, see our Window Lintel Guide or explore related categories such as cavity lintels and solid wall lintels.
