What is the primary function of a lintel?

• A. To Protect Against Moisture
• B. To Support Weight Over An Opening
• C. To Seal Joints
• D. To Anchor The Wall To The Foundation

Answer: (B)

Lintels act like a small beam over openings to carry the weight of the structure above and transfer that load to the sides of the opening. By spanning the opening, they resist bending and keep the masonry above a door or window from sagging or cracking, ensuring the wall remains stable. Moisture protection, sealing joints, and anchoring the wall to the foundation are handled by other elements and methods—flashing and drainage for moisture, mortar or sealants for joints, and footings or wall reinforcement for foundation anchoring. So the primary function is to support weight over an opening.
