Lintel

Definition

A horizontal beam placed over an opening.

Purpose

Lintels are used to support the weight of the structure above openings such as doors, windows, and fireplaces. They distribute the load to the adjacent wall sections, preventing sagging or collapse of the opening.

Examples of Use

• Doorways: Supporting the wall above door frames in both residential and commercial buildings.
• Windows: Providing structural support above window openings.
• Fireplaces: Supporting the masonry above fireplace openings.

Related Terms

• Header: A beam that spans an opening in a wall and transfers load from above to the adjacent studs.
• Transom: A horizontal crosspiece over a window or door.
• Sill: A horizontal member at the bottom of a window or door opening.

Notes

• Lintels can be made from various materials, including wood, steel, concrete, or stone.
• The choice of material and size depends on the load requirements and span of the opening.
• Proper installation is essential to ensure the lintel provides adequate support and distributes loads correctly.
